AI Investors

The firms on this page invest in AI companies while they are still small. Most of them write seed and Series A checks, and several led the first institutional round for the companies listed: a Berlin, Germany, developer of speech models for European languages, a San Francisco, California, company whose AI agents answer hotel phones, a memory chip startup in Los Altos, California, and an Israeli database built for AI agents.

Each profile lists a firm's leaders, short stage and focus tags, its check size where the firm has stated one, and the AI companies it has backed. Every deal links to the funding announcement, press report or portfolio page that records it. Firms are listed in alphabetical order.
