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.

How this works

One AI-native engineer.
The output of a team.

One senior engineer plus AI agents now ships saas development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in San Francisco who need to ship before the next round closes.

The local read

Why saas development is hard in San Francisco

SF founders compete with OpenAI, Anthropic, and every Series B sitting on $200M in dry powder. A senior engineer offer that actually wins here is $400K all-in, plus relocation, plus equity refreshers. At seed stage that's most of the round.

One named engineer with AI agents now does what a four-person team used to. Three-week timelines instead of three months. Flat-price quote in 24 hours after a discovery call. Pacific Time, overlap with your Sand Hill investors and your early customers in the same window. Code in your GitHub from commit one.

Hiring one senior engineer here is a ~$310K year-one outlay and a 60–90 day search. Our saas development engagement starts at $12,000 with a first deploy in 4–8 weeks.

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.
