Overview
We build software to a written specification — SaaS products, API and systems integrations, internal platforms, and the unglamorous backend work that keeps them running. Before anyone writes code, you get acceptance criteria you can hold us to. Fixed price against those criteria. You work with one person: Dalton Redden, our principal engineer, based in St. Louis. He runs the architecture, writes the spec, reviews every pull request, and is the person you message at 4pm on a Thursday. No account manager relay, no ticket queue, no rotating cast. Behind that: a standing bench of specialist engineers. Every project is decomposed into isolated packages with strict TypeScript interface contracts, so the people building the parts can build them in parallel without stepping on each other — and every merge has to pass the same automated gate before it reaches your repository. Lint, typecheck, tests, coverage. Nothing ships green-by-assertion. What we actually build: subscription and usage-based SaaS from schema to Stripe; payment and billing systems where "charged twice" is not an acceptable failure mode; two-way syncs between CRMs, ERPs and internal databases; admin panels and operations tools your team will use every day; AI and automation pipelines with human approval gates; and rescue work on codebases someone else left behind. If you're not sure what you need yet, that's the normal case. Send us the problem and we'll come back with a written scope, acceptance criteria and a fixed number — before you commit to anything.
