Instead of renting per-seat SaaS, we self-host and customize proven open-source platforms on your own cloud — AWS or wherever you host. You move faster than a ground-up build and keep full control of your data, code, and costs.
Connect it to everything else
We build custom REST and GraphQL APIs and integrate your software with the payments, CRMs, email, AI models, and data tools you already use — or any service with an API.
Senior engineering, no agency overhead
We start from the goal
Every project begins with the business outcome and works backward to the smallest software that delivers it. No scope you didn’t need.
You own everything
Open-source foundations and clean, documented code mean the work is yours to run, change, or take elsewhere — permanently.
Direct to a senior engineer
No account managers or hand-off chains. You work with the person writing the code, so decisions and shipping happen fast.

Deployed and scaled on your own cloud.
