About Cynsta
Cynsta is LLM CI for AI features: a control layer that adds tests, guardrails, logging, and a Flight Recorder view on top of any model.

Cynsta grew out of our work on stress-testing AI systems and building compliance tooling like CAIRA. After watching teams ship LLM features with almost no tests, we decided to build the runtime that makes AI changes safe by default.
We're a small, product-focused team based in Prague with remote colleagues across the EU and US. We ship fast, talk directly to customers, and keep the company simple – no legacy stack, no giant org chart, just a tight loop between product, infra, and real deployments.
If you're excited about making AI features boringly reliable – with tests, guardrails, and governance built in – take a look at our open roles or email us at hello@cynsta.com.
Our mission is to make AI features as testable and observable as any other part of the stack. That means CI for prompts and flows, runtime guardrails where calls actually run, and a Flight Recorder view whenever something behaves unexpectedly.
We're pragmatic about AI in production: tests before tuning, evidence over vibes, provider-agnostic by design, and compliance you can switch on when regulators start asking. We work with support, fintech, and SaaS teams to make sure Cynsta solves real reliability and governance problems – not just add dashboards.
