Ship AI features & agents that actually work in production.

Automated, deterministic evals for AI teams that ship. Stop guessing, start shipping.

Agents can't work without deterministic evals

Teams stuck in beta are still tweaking spreadsheets and hoping LLM-as-judge catches issues. Teams shipping to production run deterministic evals on everything.

The evaluation layer designed for the agentic era

Purpose-built for agents, tool calling, and RAG. Not another LLM-as-judge wrapper - actual deterministic evaluation models trained specifically for the complexities of production AI.

Ship 10x faster than teams running manual evals & LLM as Judges

While they're on week 3 of tweaking rubrics, you've already shipped 5 releases.

Actually catch issues before customers

Teams using Composo find problems in minutes. Everyone else finds out from support tickets.

The difference between 'coming soon' and 'live with Fortune 500s

Why teams that ship choose Composo

Instant set up - 3 lines of code

Teams using Composo ship their first release today. Teams building LLM as a Judge rubrics are still 'preparing to evaluate' 3 months later.

Enterprise-ready from day one

Built for enterprise-scale teams, with robust compliance and secure integration into your stack.

>95% accuracy not 70% guesswork

The difference between shipping with confidence and hoping customers don't notice the bugs.

Agents can't work without this

Teams with >95% accurate evals ship agents daily. Teams with 70% accuracy are still in beta.

Proven on millions of production traces

Not academic theory. Battle-tested on real agent failures from teams actually shipping.

Any criteria in one sentence

Write what good looks like. Ship in minutes. No PhD in prompt engineering required.

We're trusted by the best teams in AI

Proven results across startups & enterprises in the most complex verticals

"We were finding LLM as a Judge far too unreliable - the same response would score 40% one day and 70% the next. Composo gave us the deterministic scoring we needed to actually track improvements. Game changer for our ML team."

Fortune 500 Financial Services

"This is awesome. We replaced our entire LLM-as-judge system in one afternoon. We just run all our outputs through Composo and get super powerful metrics on performance. Why would anyone do it the old way?"

CTO

Series B Healthcare AI Startup

"Our enterprise clients demand quantitative proof that our AI agents are accurate. Composo's 92% accuracy finally gave us the hard metrics we needed to prove our system delivers on its promises."

VP of Product

Legal Tech Company

"We cut our QA cycle time by 70%. Instead of relying purely on human review, now we instantly know which prompts are failing and why. The detailed analysis helps us fix issues before they hit production."
