San Francisco / Bay Area
Senior engineering for
Bay Area founders
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.

How this works
One AI-native engineer.
The output of a team.
One senior engineer plus AI agents now ships what four engineers used to. 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 this works for the Bay
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.
