Anthropic

Anthropic's startup program provides free Claude API credits so you can experiment and build with confidence, along with the highest tier of publicly available rate limits to ensure smooth operation as you scale. The program includes invitations to exclusive founder events and workshops, plus access to the Claude Developer Platform and Console with pre-built cookbooks, guides, and prompt caching for cost optimization. Top portfolio companies from a16z build with Claude.

Notable companies in the program include StackBlitz (CEO Eric Simons: 'Claude Sonnet is the enabling technology that made this product possible, period'), Replit (CEO Amjad Masad), Augment Code (Co-founder Guy Gur-Ari), and Lovable (CEO Anton Osika: '20 times faster than writing code themselves'). The platform supports Claude API, Claude Code, and the Claude Console for building, testing, and iterating on AI deployments.
