Voice Agent Testing Pricing: What QA, A/B Testing, and Conversation Validation Actually Cost in 2026
Real 2026 pricing for voice agent testing — conversation QA, A/B variant testing, shadow testing, red-team validation, and ongoing regression monitoring. Pilot ($1.5k–$4k), pre-launch ($3k–$9k), and ongoing QA ($600–$2,800/mo) cost breakdowns by use case.

Most buyers shopping voice agent platforms ask the wrong pricing question. They ask "what does it cost per minute to run?" — when the question that actually decides whether the agent ships is "what does it cost to validate that it should ship?" Those are two different budgets. The platforms know this and conflate them on purpose. "Testing" gets quoted as 50 free trial minutes at the same per-minute rate as production, which is not testing — it's a tasting menu. Real pre-launch validation has five distinct cost components, and at least four of them never show up on a platform pricing page.
This post separates the two budgets cleanly. Below, we break down what voice agent testing actually costs in 2026 across pilot validation, pre-launch validation, and the ongoing QA program once the agent is live — for inbound receptionists, outbound SDR agents, multi-language deployments, and HIPAA-regulated workflows. For what it costs to run a voice agent once it's validated, see the AI voice agent costs compared breakdown and the voice agent pricing guide.
TL;DR: Voice agent testing has 5 distinct cost components: conversation QA ($500–$2,500), A/B variant testing ($400–$1,800 per test), live shadow testing ($800–$3,200), red-team / adversarial testing ($600–$2,400), and ongoing regression monitoring ($200–$1,400/mo). For a first pilot, plan $1,500–$4,000 all-in. For full pre-launch validation before going live to real customers, plan $3,000–$9,000. Once live, ongoing QA is $600–$2,800/month. A reasonable Year-1 testing budget for an enterprise voice agent — pilot + pre-launch + 12 months of ongoing QA — lands at $9,000–$28,000. That budget is rounding error against the revenue impact of an unvalidated agent mishandling 36–84 calls per month.
Key Takeaways
- Voice agent testing breaks into 5 cost components: QA, A/B testing, shadow testing, red-team, and ongoing regression monitoring
- A first pilot validation lands at $1,500–$4,000 all-in for a low-complexity inbound use case
- Full pre-launch validation before going live runs $3,000–$9,000 for a standard deployment
- Ongoing QA programs cost $600–$2,800/month depending on call volume and regulatory profile
- Total Year-1 testing budget for an enterprise agent: $9,000–$28,000
- HIPAA-regulated voice agents require $6,000–$12,000 pre-launch testing alone — 2–3x a standard deployment
- A poorly validated agent mishandles 3–7% of calls at launch; on 1,200 calls/month that is 5–12 lost bookings worth $2,500–$18,000/month
- "Per-minute" testing pricing from DIY platforms hides 40–120 hours of QA engineering at $80–$200/hour — the real test cost isn't the minutes, it's the labor
- Shadow testing (AI running alongside a human handler for 1–4 weeks) is the single highest-ROI test component and the one most platforms skip
The 5 Components of Voice Agent Testing Cost
Voice agent testing is not one line item. It is five distinct workstreams that each produce a different kind of evidence about whether the agent is ready to handle real callers. Buyers who treat testing as a single budget category consistently underspend on the components that catch the most expensive failures.
Component 1: Conversation QA / Script Coverage Testing — $500–$2,500
The baseline. Conversation QA is the structured run-through of every documented intent, escalation path, and edge case in the agent's playbook. For an inbound receptionist that means coverage of new-customer inquiries, existing-customer lookups, scheduling, rescheduling, cancellations, after-hours handling, transfer-to-human triggers, and the 10–25 most common questions specific to the business.
What's in the budget:
- Scenario inventory (15–40 documented intents)
- 3–5 scripted calls per intent (45–200 test calls total)
- Pass/fail grading against a rubric
- Failure-mode log and remediation list
Cost range: $500–$2,500 depending on intent count and how much of the work is automated vs human-graded. Automated QA against transcripts is cheap; human-graded conversation quality is not. Most teams that do QA at all spend $1,200–$1,800 here for a first deployment.
What gets skipped at the low end: Tone grading, hold-music handling, mid-conversation interruption recovery, and the "long tail" intents that account for ~15% of calls but ~40% of complaints.
Component 2: A/B Testing Voice/Script Variants — $400–$1,800 per Test
The most underspent component. Voice agents have at least six independently testable variables: voice model, opening greeting, escalation threshold, hold behavior, qualification script, and post-call wrap-up. Most deployments ship one configuration of all six and call it done. A real A/B program tests 2–4 variants per variable against live (or shadowed) call volume and picks the winner.
What's in the budget per test:
- 2–4 variants designed and configured
- Allocation logic (call routing or shadow-only)
- 200–600 calls per variant minimum for readable signal
- Statistical analysis and recommendation
Cost range: $400–$1,800 per test. A full pre-launch A/B program typically runs 3–5 tests in sequence (voice + greeting + escalation threshold are the high-leverage three), so total A/B spend at pre-launch is $1,200–$5,400.
Why it matters: The lift between a median voice model and the best-fit voice model for a specific vertical is typically 8–14% in conversion-to-booking. On 1,000 monthly bookings that's 80–140 bookings of pure A/B-attributable lift, which dwarfs the test cost in the first month it ships.
Component 3: Live Shadow Testing — $800–$3,200
Shadow testing runs the AI agent on real calls in parallel with the human handler — the customer talks to the human, but the AI receives the same audio and produces its response in the background. The two outputs are compared without the customer ever experiencing a buggy AI response. This is the single highest-fidelity validation method available and the one most DIY platforms quietly omit because it requires real telephony plumbing on the customer's side.
What's in the budget:
- Telephony fork / sidecar configuration
- 1–4 weeks of parallel running (typically 2 weeks)
- 400–2,000 shadow calls compared against human handling
- Divergence log: where the AI said something the human did not
- Severity grading of divergences (acceptable / coachable / blocker)
Cost range: $800–$3,200 depending on call volume during the shadow window and how much of the divergence analysis is human-graded. At the low end, $800 buys an automated transcript-diff against ~500 shadow calls. At the high end, $3,200 buys human grading of every divergence with a labeled severity rubric.
Why it matters: Shadow testing catches the failure modes that QA scripts cannot — the calls nobody knew to script for. A typical 2-week shadow surface 8–25 "unknown unknown" intents that weren't in the original scenario inventory. Catching those before launch versus after launch is the difference between a quiet rollout and a public-facing rollback.
Component 4: Red-Team / Adversarial Testing — $600–$2,400
Pen-testing for voice agents. The red-team workstream deliberately tries to break the agent: jailbreak attempts ("ignore your instructions and..."), abusive callers, prompt injection through customer-supplied data (names, addresses, dictation fields), accent and dialect stress tests, hearing-impaired caller simulation, non-native-speaker scenarios, and edge cases like callers who hand the phone off mid-conversation.
What's in the budget:
- 8–20 documented attack categories
- 3–10 attempts per category
- Pass/fail grading with severity tagging
- Mitigation playbook for any blocker-tier finding
Cost range: $600–$2,400 depending on attack surface and how much regulated-data exposure the agent has. A consumer-facing inbound receptionist with no payment data sits at the low end. An outbound healthcare scheduler with PHI exposure sits at the top.
What this catches: Most voice agent platforms have at least one model-level vulnerability that did not exist three months prior — because the underlying LLM provider shipped a model update. Red-teaming is the only test that surfaces these regressions before a customer does.
Component 5: Ongoing Monitoring / Regression Testing — $200–$1,400/month
Continuous validation after launch. The underlying LLM provider ships model updates on a roughly quarterly cadence; voice and STT providers ship updates more often than that. Each update can silently shift agent behavior — sometimes for the better, sometimes for the worse. Without ongoing regression testing, those shifts only surface through complaints.
What's in the monthly budget:
- 50–200 automated regression calls per week against a fixed golden-set
- Drift detection on key intents (escalation rate, average handle time, transfer rate)
- Sampled human grading on 1–3% of live calls
- Alert thresholds and weekly drift report
Cost range: $200–$1,400/month depending on call volume. Low-volume deployments (under 1,000 calls/month) sit at $200–$500. Mid-volume (1,000–10,000 calls/month) sit at $500–$1,200. High-volume or regulated deployments sit at $1,000–$1,400.
Why it matters: Without it, the 3–7% mishandle rate that pre-launch testing reduced to 0.5–1.5% drifts back upward over 4–9 months. Ongoing QA is what holds the gain.
Pilot Testing Pricing — $1,500–$4,000 All-In
A pilot is the first validation pass on a brand-new agent before any real customer touches it. Pilot testing is deliberately light — the agent is new, the scenarios aren't all known yet, and the goal is to find showstoppers, not to certify production-readiness.
| Component | Pilot Budget | What's Included |
|---|---|---|
| Conversation QA | $500–$1,200 | 10–20 documented intents, 3 calls per intent |
| A/B testing | $400–$800 | 1 test (typically voice model or greeting) |
| Shadow testing | $0–$800 | Optional at pilot; full version at pre-launch |
| Red-team | $300–$700 | Light pass — 6–10 attack categories |
| Setup / configuration time | $300–$500 | Test environment, scenario inventory, scripts |
| Pilot total | $1,500–$4,000 | Validates "should we keep going" decision |
What you get out of pilot testing: a clear go/no-go on the agent's baseline behavior, a documented gap list (intents not covered, edge cases not handled), and the inputs needed to scope full pre-launch validation. Pilot is not a launch certification. A passed pilot means the agent is ready for pre-launch testing — not ready for real customers.
Pre-Launch Validation Pricing — $3,000–$9,000
Pre-launch is what you do once the agent has cleared pilot and is being prepared for real customer traffic. The goal here is to reduce the launch-day mishandle rate from the unvalidated baseline of 3–7% down to the post-validation target of 0.5–1.5%.
| Component | Pre-Launch Budget | What's Included |
|---|---|---|
| Conversation QA | $1,200–$2,500 | Full intent coverage (25–40 intents, 5 calls per intent) |
| A/B testing | $1,200–$2,800 | 3 tests in sequence (voice, greeting, escalation) |
| Shadow testing | $800–$2,400 | 2-week parallel run, 400–1,500 shadow calls |
| Red-team | $600–$1,800 | Full attack surface, 12–20 categories |
| Documentation | $200–$500 | Failure-mode runbook, escalation playbook |
| Pre-launch total | $3,000–$9,000 | Validates "ready for real customers" decision |
What pre-launch validation produces:
- A documented baseline mishandle rate for the agent at launch
- A coverage matrix mapping every supported intent to a tested scenario
- A divergence log from shadow testing with closed remediations
- A red-team report with severity-tagged findings, all blocker-tier resolved
- A monitoring runbook for the ongoing QA program
The single biggest predictor of whether a voice agent launch goes smoothly is whether the team did real shadow testing during pre-launch. Teams that skip it report 2–4x higher escalation rates in the first 60 days post-launch.
Ongoing QA Program Pricing — $600–$2,800/Month
Once the agent is live, the testing budget shifts from one-time validation spend to a recurring monitoring program. This is where most deployments under-invest — the pre-launch numbers look pristine on day one and quietly drift over the next 6–9 months without continuous validation.
| Volume Tier | Monthly QA Budget | What's Included |
|---|---|---|
| Low (< 1,000 calls/mo) | $200–$600 | Weekly golden-set regression, 1% live sample grading |
| Medium (1,000–5,000 calls/mo) | $600–$1,400 | Daily regression, 2% live grading, monthly drift report |
| High (5,000–15,000 calls/mo) | $1,200–$2,000 | Real-time drift alerts, 3% live grading, A/B refresh quarterly |
| Enterprise (> 15,000 calls/mo) | $1,800–$2,800 | Full continuous validation, dedicated QA analyst time |
What ongoing QA buys you that you can't buy with pre-launch alone:
- Drift detection — catches model-update regressions before customers complain
- New-intent discovery — surfaces the call patterns that weren't in the original scenario inventory
- Refresh A/B testing — re-tests voice/greeting/escalation quarterly as audience evolves
- Compliance evidence — for regulated verticals, the audit log that proves the agent is being validated continuously
A team running $1,000/month ongoing QA on a $4,000/month voice agent deployment is spending 25% of run-cost on validation. That ratio sounds high until you compare it to the QA budget of any other production system handling 5,000+ customer interactions per month.
Testing Cost by Platform: What's Included vs Charged Separately
The cleanest way to compare platforms isn't the headline per-minute rate — it's what each one bundles into the platform fee versus what gets billed separately or punted to the customer's engineering team.
| Platform | Conversation QA | A/B Testing | Shadow Testing | Red-Team | Ongoing Monitoring |
|---|---|---|---|---|---|
| Prestyj | Included pre-launch | Included (3 tests) | Included (2 weeks) | Included | Included in plan |
| Bland AI | DIY / customer | DIY | Not offered | DIY | Per-minute usage |
| Air.ai | Light included | Customer-driven | Available add-on | DIY | Basic dashboards |
| Synthflow | DIY | DIY | Not natively offered | DIY | Basic call logs |
| Retell AI | DIY | DIY | DIY (you build it) | DIY | Webhook logs only |
Reading this table: "DIY" means the platform does not provide it — your team builds, runs, and pays for it. For DIY platforms, the real test budget isn't zero; it's the 40–120 hours of QA engineering time at $80–$200/hour that the customer absorbs. That's $3,200–$24,000 in engineering labor before the agent is validated, on top of any per-minute usage charges during testing.
For a deeper platform-by-platform cost breakdown on the production side, see AI voice agent costs compared.
What's Hidden in "Per-Minute" Testing Pricing
Many voice AI platforms quote testing the same way they quote production: a per-minute usage rate, typically $0.15–$0.31 fully loaded. By that logic, "testing" a voice agent costs ~$0.20/min × 800 test minutes = $160. That number is wildly misleading and it's the single biggest source of under-budgeted voice agent projects.
What the $160 number leaves out:
- The QA engineer's time designing scenarios, grading transcripts, and remediating findings: 40–120 hours at $80–$200/hour = $3,200–$24,000
- The telephony reconfiguration required to fork calls for shadow testing
- The A/B testing harness — variant routing, allocation logic, statistical analysis tooling
- The red-team contractor if you don't have one in-house: $1,500–$5,000 for a focused engagement
- The regression infrastructure to keep monitoring the agent after launch
The per-minute rate measures one of the smallest cost components in real testing. Treating it as the testing budget is like treating the cost of paper as the budget for printing a magazine. Everything that matters happens around it.
This is why managed platforms that bundle testing into the plan price (Prestyj, certain Air.ai tiers) often come in cheaper on actual testing-out-the-door cost than DIY platforms whose per-minute rate is lower but whose hidden QA labor is higher.
Testing Pricing by Use Case
Testing cost is not flat across deployments. The complexity of the conversation, the regulatory profile, and the linguistic surface area drive 3–5x cost differences for the same component.
Inbound Receptionist (Low Complexity) — Pilot $1.5k–$3k
The simplest case. Documented intent set is small (15–25 intents typical), regulatory exposure is low, conversations are short (60–180 seconds average). Pilot validation lands at $1,500–$3,000 all-in. Pre-launch validation lands at $3,000–$5,500. Ongoing QA runs $400–$1,000/month.
This is the use case most home services operators are running. For a deeper view of how voice agents stack against humans in this category, see AI receptionist vs human receptionist.
Outbound SDR / Sales (Medium Complexity, Regulated) — Pre-Launch $3k–$6k
Outbound voice agents carry TCPA, state-level dialing law, and call-recording disclosure obligations. The conversation surface is also wider — discovery, objection handling, qualification, and disposition. Pre-launch validation lands at $3,000–$6,000. Red-team testing is meaningfully more expensive here ($1,200–$2,400) because regulatory edge cases double the attack surface. Ongoing QA runs $1,000–$1,800/month.
Multi-Language / Accent-Heavy (High Complexity) — Pre-Launch $5k–$9k
Multi-language deployments multiply the QA matrix. A bilingual EN/ES agent isn't 2x the QA work — it's closer to 2.5x, because language-switching mid-call (code-switching) adds a third test surface beyond either language alone. Heavy-accent markets (Caribbean English, Southern US, regional Spanish) require additional shadow testing with native-speaker grading. Pre-launch validation lands at $5,000–$9,000. Ongoing QA runs $1,500–$2,400/month.
Healthcare / Regulated (HIPAA, Scripted Compliance) — Pre-Launch $6k–$12k
The most expensive category. HIPAA-regulated voice agents require documented compliance evidence at every test layer: PHI handling in transcripts, scripted disclosures, audit-grade call logging, BAA-covered vendors across the stack, and red-team coverage that includes prompt-injection scenarios attempting to extract PHI. Pre-launch validation lands at $6,000–$12,000. The premium over a standard deployment is almost entirely red-team and compliance documentation. Ongoing QA runs $1,800–$2,800/month because audit-grade evidence has to be continuously generated, not just produced once.
For a deeper view of what HIPAA voice agent setup actually requires, see the HIPAA-compliant AI receptionist guide.
ROI of the Testing Investment
The single best way to size a testing budget is to compare it against the cost of not doing the testing. The math is unkind to deployments that try to skip pre-launch validation.
Baseline failure rate of an unvalidated voice agent: 3–7% mishandled calls (escalations that didn't need to escalate, dropped intents, wrong-answer events, abandoned callers).
Failure rate after full pre-launch validation: 0.5–1.5%.
Net mishandle reduction from $5,000 of pre-launch testing: ~4 percentage points on average.
Now plug that into call volume:
| Monthly Call Volume | Mishandled Calls Saved | Lost Bookings Prevented | Revenue Impact (at $500 avg job) |
|---|---|---|---|
| 500 calls/mo | 20 calls | 2–5 bookings | $1,000–$2,500 |
| 1,200 calls/mo | 48 calls | 5–12 bookings | $2,500–$6,000 |
| 5,000 calls/mo | 200 calls | 20–50 bookings | $10,000–$25,000 |
| 15,000 calls/mo | 600 calls | 60–150 bookings | $30,000–$75,000 |
Payback math: A $5,000 pre-launch investment on a 1,200 calls/month deployment pays back in 0.8–2.0 months. At 5,000 calls/month, payback is under a month. At enterprise volume, payback is measured in days. Anyone touching 15,000+ calls/month who skips pre-launch validation is leaving $30,000–$75,000/month on the table to save $5,000 once.
For a fuller view of the integration and ongoing-cost surface, see the voice agent integration guide and the setup cost breakdown.
Prestyj Testing Pricing Structure
Prestyj bundles testing into the deployment plan rather than billing it as a separate line item. The tier you pick determines what testing depth comes included.
| Prestyj Tier | Pilot Testing | Pre-Launch Validation | Ongoing QA | Use Case |
|---|---|---|---|---|
| Pilot | $1,800 flat | Not included | Not included | Validate before plan commit |
| Solo / Team | Included | $3,500 included | $500/mo included | Inbound receptionist, low volume |
| Brokerage / Mid-Market | Included | $6,000 included | $1,200/mo included | Outbound SDR, multi-channel |
| Enterprise / Regulated | Included | $9,000–$12,000 included | $2,000–$2,800/mo included | HIPAA, multi-language, high-vol |
What's structurally different about bundled testing:
- The QA workstream is owned end-to-end by the platform — not split between platform fees and customer engineering hours
- Shadow testing infrastructure is preconfigured, not built per-customer
- Red-team coverage is run against a shared library that updates as new attack categories emerge
- Ongoing regression testing runs continuously without the customer scoping monthly QA hours
The TCO comparison: a DIY platform at $0.18/min plus 80 hours of QA engineering at $150/hour is $12,000 of testing labor in year one on top of usage. Bundled testing folds that labor into the platform plan and eliminates the line item.
Frequently Asked Questions
How much does it cost to test a voice agent before going live?
For a standard inbound or outbound deployment, full pre-launch validation costs $3,000–$9,000. That budget covers conversation QA across 25–40 documented intents, 3 sequential A/B tests on voice/greeting/escalation variables, a 2-week live shadow test against the existing human handler, red-team adversarial testing across 12–20 attack categories, and the documentation needed for a clean launch handoff. Pilot validation (a lighter pass to decide whether to keep going) is $1,500–$4,000. The difference between the two budgets is the depth of shadow testing and red-team coverage — pilot has light coverage, pre-launch has full coverage.
What's the difference between voice agent QA and voice agent A/B testing pricing?
Conversation QA tests whether the agent handles documented scenarios — pass/fail against the playbook — at $500–$2,500 depending on intent count. A/B testing tests which of two or more variants performs better on live (or shadowed) call volume at $400–$1,800 per test; a full pre-launch program runs 3–5 tests. QA validates that the agent is correct; A/B testing validates that it's optimized. Skipping A/B testing leaves an 8–14% conversion lift on the table. Skipping QA leaves a 3–7% mishandle rate at launch.
Do voice AI platforms charge separately for shadow testing?
Most DIY platforms (Bland, Synthflow, Retell) don't natively offer shadow testing — the customer builds the telephony fork and divergence analysis themselves, an engineering project worth $2,000–$5,000 in customer labor. Managed platforms (Prestyj, certain Air.ai tiers) bundle shadow testing into pre-launch validation. The question to ask isn't "what does shadow testing cost?" but "is shadow testing included or am I building it?" That single answer drives a $0–$5,000 swing in the testing budget.
What does ongoing voice agent QA cost monthly?
$200–$2,800/month depending on call volume and regulatory profile. Under 1,000 calls/month: $200–$600. 1,000–5,000 calls/month: $600–$1,400. 5,000–15,000 calls/month: $1,200–$2,000. Enterprise or HIPAA-regulated: $1,800–$2,800/month, because audit-grade evidence has to be produced continuously. Ongoing QA is typically 15–25% of voice agent run cost; teams budgeting less than 10% are under-investing on regression coverage.
Is testing budget worth it for a small voice agent deployment?
Yes, but the budget scales with volume. Under 500 calls/month, a $1,500 pilot validation plus $200–$400/month ongoing QA is sufficient. The ROI math still works at low volume — a 4-percentage-point mishandle-rate reduction on 500 calls saves 20 calls or 2–5 bookings worth $1,000–$2,500/month, which pays back a $1,500 pilot in 0.6–1.5 months. The only deployments where testing is overkill are internal POCs that won't see real callers.
How much testing should I budget for a HIPAA-regulated voice agent?
Pre-launch validation for a HIPAA-regulated voice agent lands at $6,000–$12,000, and ongoing QA at $1,800–$2,800/month. The premium over a standard deployment goes almost entirely into two places: red-team testing for PHI-extraction attack vectors ($1,500–$3,000 vs $600–$1,800 for non-regulated agents) and compliance documentation that has to be regenerated continuously rather than once at launch. HIPAA voice agents also require BAA-covered vendors across the full stack (LLM, STT, TTS, telephony, transcription, storage), which constrains platform choice and indirectly affects testing cost because some test components have to be re-run when a vendor changes. See the HIPAA-compliant AI receptionist guide for the full compliance surface.
Why do voice agents need ongoing testing after they're live?
Three reasons. Model drift — the underlying LLM provider ships updates roughly quarterly and each one can silently shift behavior. Audience evolution — the mix of caller intents shifts over 3–9 months as channels and seasons change; an intent that was 2% of volume at launch can become 15% within a year. Stack updates — STT and TTS providers ship updates more often than LLM providers. Without ongoing regression testing, the 0.5–1.5% mishandle rate at launch typically drifts back to 2–4% within 6–9 months. Ongoing QA holds the gain.
What's the cheapest defensible voice agent testing budget?
For a deployment that will see real customer traffic, the floor is $1,500 pilot + $3,000 pre-launch + $200/month ongoing = $7,000 in year one. Below that, you are either skipping a workstream (typically shadow testing or red-team) or running it at insufficient depth to catch failures. The teams that report the worst launch experiences uniformly come in below this floor. Anything cheaper than $7,000/year is not a testing budget — it's hoping the agent works.
Quick Reference: Testing Tier → Use Case → Cost → Expected Mishandle Rate
| Testing Tier | Use Case | All-In Year-1 Cost | Mishandle Rate Post-Testing |
|---|---|---|---|
| Pilot only | Internal POC, no real callers | $1,500–$4,000 | Not measured |
| Pilot + light pre-launch | Low-volume inbound receptionist | $5,000–$8,000 | 1.5–2.5% |
| Full pre-launch + ongoing | Standard mid-market deployment | $9,000–$16,000 | 0.8–1.5% |
| Regulated full stack | HIPAA, multi-language, enterprise | $18,000–$28,000 | 0.3–0.8% |
| No testing | "We'll fix it after launch" | $0 | 3–7% |

Ready to Scope a Defensible Testing Budget?
The teams shipping voice agents successfully in 2026 are spending 15–25% of voice agent run cost on testing and ongoing QA. The teams shipping voice agents that quietly get rolled back are spending under 5%. The difference between those two outcomes is not the platform — it's whether shadow testing and red-team validation happened before the first real customer hit the line.
Prestyj bundles all five testing components — conversation QA, A/B variant testing, live shadow testing, red-team adversarial testing, and ongoing regression monitoring — into the deployment plan. No DIY engineering hours, no separate testing line items, no per-minute "testing budget" that under-counts the labor.
In 30 minutes, we'll show you:
- The right pilot vs pre-launch budget for your specific use case
- Where your current agent is most likely to fail without shadow testing
- A red-team scoping appropriate for your regulatory profile
- The ongoing QA cadence sized to your call volume
