Angel Investors in Silicon Valley (2026)

775 investors · 775 individual angels · 57% with verified email · 0 claimed profiles

This page covers the Peninsula towns rather than San Francisco proper: Palo Alto, Menlo Park, Mountain View and Los Altos, 775 investors between them. Founders search for Silicon Valley as one place, and for raising purposes it behaves as one — the four towns sit within a few miles of each other along the same corridor.

Concentrated, technical, and hard to get into

238 of 775 name AI/ML, 31% of the area — proportionally even higher than San Francisco. Cloud infrastructure at 45, cybersecurity at 37, deeptech at 36 and robotics at 27 fill out a distinctly infrastructure-heavy picture.

This is the densest concentration of experienced technology investors anywhere, and also the most heavily solicited. The ratio of inbound pitches to available attention is worse here than anywhere else on this list.

What works is specificity and proof. What does not is volume.

The four towns individually

Palo Alto holds the largest share, then Mountain View, Menlo Park and Los Altos. Each has its own page if you want to narrow further, though for most raises the wider list is the more useful one.

441 of 775 have a verified email — 57%.
