Angel Investors in Los Altos (2026)

129 investors · 129 individual angels · 57% with verified email · 0 claimed profiles

Los Altos has 129 investors in the Robynhood database, the smallest of the four Peninsula towns covered here. It is largely residential, and its investors are disproportionately people who exited earlier technology cycles and now invest from home rather than from an office.

Why Los Altos is usually worked as part of Silicon Valley

Los Altos sits within a few miles of Palo Alto, Menlo Park, Mountain View and Los Altos, and founders raising here almost always work all four as one list of 775 investors rather than targeting one town.

Across the four, AI/ML is the dominant focus with 238 investors, followed by healthtech at 111, SaaS at 95 and fintech at 84. Cloud infrastructure, cybersecurity, deeptech and robotics are all proportionally strong — this is the most infrastructure-heavy investor population in the database.

Sector figures are held at the combined level rather than per town, because splitting them four ways produces numbers too small to mean anything.

What to expect

This is the most heavily solicited investor population anywhere. A generic pitch will not be read. Specificity and demonstrable progress are what get attention.

Roughly 57% of Peninsula investors have a verified email address on file, and all have verified LinkedIn profiles.
