Harness · Evals · MaintenanceRunning live agents in production today

Your voice agent works in the demo. We make it work in production.

Anyone can build a voice agent now. Almost nobody can keep one reliable on real calls — interruptions, accents, background noise, mid-call topic switches, and the silent regressions every prompt change ships. That’s the part we do: we build the eval harness, run it continuously, and maintain your agent in production.

Demos are easy now — the platforms build one from a prompt. Production is where voice agents die, and it’s an engineering problem, not a model problem.

Start free: we’ll break your agent before your callers do

Send us your agent’s number or demo. We run 15–20 scripted test calls against it — interruptions, accents, background noise, mid-call topic switches, edge intents — and send you the top 3 failures we found, with timestamps and transcripts. No call required, nothing to install. If nothing breaks, you’ll know that too.

The Production Readiness Audit

A fixed-price eval pass over your agent’s real scenarios. You get the numbers, the causes, and the shortest path to production-grade. $1,500–$3,000, credited toward the build if we do the fixes.

A scored eval report

50–100 test calls across your real scenarios, scored on task completion, latency, interruption recovery, and transcription accuracy. Numbers, not vibes.

A failure taxonomy

Every failure classified by root cause — speech recognition, prompt logic, tool calls, latency, context loss — so fixes target causes, not symptoms.

A fix plan ranked by impact

The shortest path from your current pass rate to production-grade, ordered by how many failures each fix eliminates.

A regression baseline you keep

The eval suite is yours. Every future prompt, model, or tool change gets tested against it — no more silent regressions shipped to callers.

A fixed-price quote for the fixes

A number, not a range. Take it — or keep the report and fix it with your own team.

Then we build it right — and keep it right

Build · $5–20K fixed

Production-grade from day one

The agent ships WITH its harness: eval suite, call-data capture, observability dashboard, and alerting. Not a demo with a phone number — a system you can trust and measure.

Run · from $2K/mo

We operate the eval layer

  • Continuous evals on live traffic — pass rates tracked call over call
  • Every prompt or model change regression-tested before it ships
  • Monitoring and alerting — we know it broke before your callers tell you
  • Fixes included, plus new eval scenarios added every month

A real production call, not a demo reel

From a system we build and operate — note the mid-call repair at 0:30 when the lead asks the agent to repeat itself. That recovery is harness work, not luck.

We run these systems ourselves

Our agents answer real customers and dial real leads every day. The ~9/10 execution accuracy isn’t a promise — it’s a measurement from our live production agent, published in AssemblyAI’s customer story about our work.

Who this is for

Good fit

  • Teams with a voice agent in pilot or production that isn't reliable yet
  • Funded voice-AI startups that need an eval layer, not more demos
  • Product teams adding voice to an existing product
  • Companies building on AssemblyAI, Retell, Vapi, or ElevenLabs

Not for

  • Looking for your first throwaway demo bot
  • Weekend experiments without a production target
  • Shopping for a website chatbot
