Built for SF product cycles: API integrations, dashboards, and workflow tools

San Francisco product teams move fast and expect their tools to keep up. That means web applications that connect cleanly to the APIs your stack already depends on — Stripe, Salesforce, HubSpot, Slack, or custom internal services — rather than forcing a rebuild every time requirements shift. Dashboards that surface the right metrics without burying your team in configuration. Workflow tools scoped tightly to the actual bottleneck, not a feature list padded for a sales deck. FNA builds around that rhythm: we scope before we quote, identify integration points early, and flag scope creep before it hits your budget. If you're pre-Series A and need an MVP that can survive a demo day, or post-funding and replacing a fragile internal tool, the architecture decisions made in week one matter. We document them, explain the tradeoffs, and hand off code your next hire can actually read.

How we scope a San Francisco MVP without burning your runway

San Francisco founders face a specific pressure: investors want proof of traction before you've had time to build anything worth showing. Our scoping process starts with a single question — what is the smallest working version that lets a real user accomplish the core task? From there we map dependencies, flag anything that can be replaced with an off-the-shelf integration in the short term, and produce a written scope document before a single line of code is written. That document includes a feature list, a cut list (features deliberately deferred), and a plain-language explanation of why each decision was made. You keep the document regardless of whether you hire us. Pricing is fixed per milestone, not hourly, so there are no invoices that expand as the project does. For pre-seed and seed-stage teams especially, knowing the exact cost of milestone one before committing is the difference between a manageable bet and an open-ended liability.
