SaaS Development
in San Francisco

Multi-tenant, billed, deployable. Not a prototype.

We build production SaaS products for founders in San Francisco — multi-tenant from day one, Stripe-ready, with the admin tooling you'll actually need at 100 customers. One senior engineer owns the architecture; you don't pay for a three-person team to argue about microservices.

Source + infrastructure handed to your accounts

Why this works for San Francisco

The local math

67% of the YC W26 batch was California-based. SF concentration is accelerating, not dying. The problem isn't density — it's that hiring a senior engineer here costs $400K and takes 90 days. Capital burns. Investors notice. We ship the first version in two weeks, flat-priced, before the next round closes.

Year-one outlay for a single senior hire in San Francisco: ~$310K. Our saas development engagement starts at $12,000.

FAQ

Common questions about saas development in San Francisco

How fast can you start?

Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Do you handle Stripe end-to-end?

Yes — checkout, customer portal, webhooks, dunning, upgrade/downgrade prorating, trial logic. We assume you want it billed-ready, not a 'connect Stripe later' placeholder.

Can you do enterprise features (SSO, audit log)?

Yes — SSO via WorkOS or Clerk, audit logs, role-based access. Most are quick adds because the multi-tenant base is already correct.

Who owns the code?

You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
