About

Building the default engineering brain

Mergic is a vertically-integrated, agent-native company building the autonomous code reviewer that every software company will run their PRs through.

Why we’re building this

Code review is the #1 bottleneck in modern engineering. Senior engineers spend 30–40% of their time reviewing PRs — and most reviews miss the subtle bugs that actually break production. Static analyzers catch around 15% of real issues.

Then AI-generated code arrived. Review volume has 5×’d. Review quality has degraded. We watched our friends — staff engineers at fintechs, infra companies, and SaaS unicorns — burn out playing whack-a-mole with PRs.

Mergic is what we wished existed. An AI senior engineer that’s read your entire codebase, watched your last 90 days of incidents, and never gets tired.

Our values

How we operate

Reliability over demos

If it works once on stage, that’s entertainment. We ship to production or we don’t ship.

Measure everything

Every claim has a number behind it. Public benchmarks. Customer-visible accuracy dashboards.

Trust is earned

Confidence scores. Abstention. Human-in-the-loop by default. Your trust is the only thing we don’t want to optimize away.

Craft is moat

In an era of commodity models, design and engineering taste are the only sustainable advantages.

Open by default

Open-source eval harness, public benchmarks, public roadmap. Closed only where customer data demands it.

Ship weekly

Small team, weekly releases, zero meetings on Wednesdays. Velocity beats headcount.

Team
