GitHub App that auto-fixes lint, writes missing tests, and suggests refactors on open PRs via Codex — pushed as commits before human review.

Customer: Solo engineering lead or CTO at a 5-20 person product startup using GitHub, shipping fast, drowning in review backlog — not enterprise, not a solo hobbyist. Probably running TypeScript/Python monorepo, has CI but no dedicated QA.

Problem: PR review is the new bottleneck: devs ship faster with Codex but reviewers still manually catch missing tests, lint drift, and obvious refactor smells. Review queue grows; senior eng time gets eaten.

Pricing: saas-mrr — $800 MRR in 4 months (8 teams at $99/mo)

Why now

Enterprises are formally adopting agentic coding (Uber, Travelers cited). Velocity gains are real and documented. Review bottleneck is now the loudest complaint — timing is 6-12 months before big players (GitHub Copilot, Linear) absorb this natively.

Go-to-market

1. Post a working demo on r/ExperiencedDevs and Hacker News Show HN — real PR before/after, no vaporware. Target 50 beta signups from organic.
2. Cold DM 20 CTOs in Y Combinator S24/W25 batch via LinkedIn — frame as ‘your Codex ROI leaks at review time, here’s the fix.’ Offer 60-day free pilot.
3. Ship GitHub Marketplace listing on day 1 — install friction must be under 3 minutes. Marketplace gives organic discovery from eng teams already shopping.
4. Partner with one Codex-forward dev influencer (e.g. Theo, ThePrimeagen adjacent) for a demo video — barter with lifetime free access.

Moat (or lack thereof)

No real moat. GitHub can ship this in a Copilot update; they probably will within 18 months. Defensibility is purely speed-to-market, workflow stickiness (teams that depend on the commit format / config), and price undercutting when GitHub charges enterprise rates. Build fast, get paying customers, then either grow to acquisition target or pivot to vertical (e.g. Solidity-only, or Rails-only with opinionated rules). Don’t pretend otherwise.
