San Francisco startup development — for founders who know what they're building.
SF founders are surrounded by the world's best startups. They know what a great product looks like, they know what investor-ready means, and they know what Series A technical due diligence requires. RCB Software builds SF startup products to those standards.
San Francisco startup founder who needs V1 built to the standard SF investors and enterprise customers expect
San Francisco's startup ecosystem is uniquely demanding. Investors have seen thousands of products. Enterprise customers have been pitched by every vendor. The bar for "credible product" is higher in SF than anywhere else in the world.
What SF investors look for in V1:
- A product that actually works — not a prototype with a polished first screen
- Architecture that can scale — not a pile of hacks
- Security that doesn't embarrass the company in due diligence
- A technical partner who can be cited as credible
The SF pre-Series-A development problem: Senior SF engineers cost $250,000-$300,000+ annually. For a pre-revenue company: hiring is not the answer. Fixed-price development is.

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 unforgiving. Fixed-price development is a budget line item, not an open-ended commitment.
Questions, answered.
Yes. YC-backed companies are a meaningful part of the client portfolio. YC's "build fast, get to users" culture aligns with the 8-12 week V1 delivery model.
