How it works
Same process for both branches. 100% async.
01
Buy
Pick a plan and pay via Stripe. No calls, no proposals, no scope creep.
02
Onboard
Record a Loom walkthrough of your codebase. We ask questions async via Linear.
03
We build
We work in your repo. PRs, commits, Loom updates. Full transparency on Linear + GitHub.
04
You ship
Review, merge, deploy. Your code, your repo, your infra. Zero lock-in.
Hey, I'm Gustavo. 👋
I founded Kactuz after 7+ years building fintech platforms, marketplaces, and SaaS infra. 15+ products shipped.
In 2025, I watched the vibe coding wave explode. Founders shipping MVPs in hours with Cursor and Bolt. Beautiful frontends. Broken backends. Leaking data. Zero auth.
So we built the cleanup crew. Same AI tools, senior judgment on top. No calls, no BS — just code that works in production.
If your backend is on fire, we can help. If it's not on fire yet, get an audit before it is.
