415 Venture

The most SF venture thing ever. Backing builders, hackers, founders, creators, and ideas that sound crazy until they work. 415 is the signal.

@nishanthkumar23 @MIT_LISLab @MIT_CSAIL @Meta congrats!!

Very cool. The hard part feels like turning messy multimodal data into something surgeons can actually trust in real time.

How are you thinking about noise, timing gaps, and missing context when one small detail can change the decision? And how close are the models to feeling truly reliable in the room?

SF founders, this is the bat signal.

If you are building something in San Francisco that feels too early, too weird, too technical, too niche, or too ambitious for most people to understand yet, drop it below.

No polished launch needed.
No perfect deck needed.
No “warm intro” needed.

Just tell us:
What are you building?
Why now?
Why you?

We are turning 415 Venture into the front door for SF builders.

Founders, reply below.
Investors, scout the replies.
Operators, find your next thing.
And if you are raising, DM us the deck.

Let’s see what SF is actually building.

@jayyeh Building those low-pressure “thinking partner” convos early is pure gold! turns the ask from cold transaction into warm continuation. Running company progress and investor relationships in parallel is the real meta. Thanks for sharing.
