SF · Hardware · Field guide.
The line "hardware is hard" was written by investors who got burned funding it. It is also out of date. The current generation of SF hardware companies (drones, satellites, fusion, robots) raised serious rounds because they understood what the money needs to see.
A working thing. Not a render. The bar is a prototype that demonstrates the physics, not the polish.
A cost curve, not a cost. Nobody expects your first unit to be cheap. They expect you to show, line by line, why unit one thousand will be.
A wedge market that pays before scale. The companies that raised well sold something narrow and expensive first (defense, industrial inspection, research labs) and used the revenue to fund the broad market.
A team that has shipped atoms. This is the most fundable asset and the hardest to fake. (It is also, not coincidentally, what we recruit for.)
SF and the broader Bay Area have a deep bench of firms with hardware theses: deep-tech funds, climate funds, defense-tech funds, and generalist firms that learned hardware through their drone and satellite portfolios. YC's hardware cohorts remain a real on-ramp, and several hardware-first funds run out of the city. The list changes fast; a warm intro from another hardware founder beats any list, including this one.
Raise for the milestone that removes physics risk, not for a calendar runway. Hardware rounds priced on software-style "18 months of runway" thinking tend to run out of money one prototype short of the data room.
