A* Capital

Day-to-day investment decisions are made by co-founders Arielle Zuckerberg and Bennett Siegel. Zuckerberg, formerly of Kleiner Perkins, brings institutional venture experience, while Siegel contributes operating perspective from several startups. As a lean firm, the two principals jointly evaluate and approve investments.

A* Capital targets pre-seed and seed-stage rounds, often as the first institutional investor in a company. Check sizes are reported in the $250,000 to $1 million range, positioning the firm as an initial backer rather than a follow-on or growth-stage participant.

A* Capital operates exclusively through direct equity investments in early-stage startups. There is no indication the firm makes fund commitments, purchases secondary stakes, or participates in special purpose vehicles as a limited partner.

The firm relies on the personal networks of its founders, including Arielle Zuckerberg's connections from Kleiner Perkins and the broader Silicon Valley ecosystem, as well as Bennett Siegel's operating relationships. A* Capital's willingness to lead rounds in consumer categories that have fallen out of favor with larger funds creates access to founders seeking committed early backers.
