Your support agent survived the demo. We make sure it survives the outage, the launch day and the invoice.

The problem
The vendors sell the agent and the dashboard that grades it. When traffic spikes — an outage, a product launch, a billing run — rate limits and capacity errors do the damage, and the vendor's own dashboard never runs against itself. Rainkernel does not build another support agent; we make the one you bought measurably reliable, and we report cost per resolution the way your CFO wants it.
26.5%
of agent deployments are customer service — the most common use case among 1,340 teams surveyed.
~5%
of production AI requests fail, and about 60% of those failures are rate-limit or capacity errors — a systems problem, not a model problem.
69%
of input tokens in production are system prompts; only 28% of cache-capable calls use caching — the cheapest reliability win there is.
The place nobody else holds
Independent measurement of a purchased support agent. The vendors sell the agent and the dashboard that grades it; the open work the market review found is set-up, integration and independent QA for mid-size companies — exactly the layer this package occupies, with cost per resolution reported under the Governor.
From the Lab's October 2026 review of the market — the six open places, and how we earn them.
What it does
We replay your busiest hour at 3×, 5× and 10×, inject provider rate limits and timeouts, and record what the customer saw — before a real outage runs the test for you.
A second provider or a smaller model behind a circuit breaker, with the hand-off tested, so the queue degrades to slower answers rather than silence.
System-prompt weight, caching coverage, retrieval payload size — the three places where support agents waste most of their budget and most of their latency.
An independent evaluation set of your real conversations scored for correct resolution, safe escalation and policy adherence — run by us, against the vendor's agent, every week.
Per-conversation budgets and model locks from the Agent Cost Governor, so peak traffic cannot become peak spend.
Works on Intercom Fin, Sierra, Decagon, Parloa, ElevenLabs voice agents or a custom stack. We do not sell an agent, so we have no reason to grade one kindly.

FAQ
They handle their platform's uptime. Your rate limits, your retrieval sources, your escalation policy and your bill are yours — and the vendor's dashboard grades the vendor's agent. An independent harness is how you know.
If you have none yet, that is an ordinary Build to Production engagement — six to ten weeks, $35,000–60,000, with the evaluation suite included. Most clients already have one; this package is for them.
