San Francisco software development — for the city that invented the startup.
San Francisco founders have the highest technical expectations in the country. RCB Software works with SF founders who know what excellent software looks like and need a developer who can build to that standard at a fixed price.
San Francisco-based company that needs senior software development at production quality with cost certainty
San Francisco developer costs are the highest in the world. A senior engineer at a Series A company in SF commands $250,000-$300,000+ in total compensation. For early-stage founders: hiring is premature until the product is proven.
The SF startup development reality: The investors expect a working product. The founders need a developer. The cost of an in-house hire at pre-revenue doesn't work. The alternative is a trusted developer partner who can build to production quality at a fixed price.
What SF founders specifically require:
- Code quality that a senior SF engineer would approve of in a code review
- Architecture decisions that can be explained and defended
- No lock-in — full code ownership and portability
- The ability to hand off to an in-house engineering team at Series A

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
SF burn rates are high. Fixed-price development is a line item in the budget, not an open-ended cost. Investors understand fixed-price project costs; they don't understand unlimited hourly billing.
Questions, answered.
The codebase is documented, follows standard patterns, and uses the same technology stack most SF engineers know (Next.js, TypeScript, Postgres). Handoff is built into the project.
