Meet Our Partners
OpenAI OpenAI is the AI Partner for The World's Largest Hermes Buildathon, giving thousands of builders across 10 cities free API credits to prototype and ship AI agents on GPT-5.5. After India's first OpenClaw Buildathon together, we're building again at global scale.
Convex Convex is the Database Partner, giving builders real-time sync, backend functions, workflows, and vector search so they skip backend plumbing and ship faster. GrowthX's own community platform is built on Convex, so this is a product we deeply believe in.
Wispr Flow Wispr Flow is the Dictation Partner, letting builders dictate prompts, PRDs, docs, and implementation plans far faster than typing, with support for technical language and codebase context. In an 8-hour buildathon, teams move at the speed of thought.
ElevenLabs ElevenLabs is the Voice Partner, giving agents a voice, personality, and real conversational ability through voice cloning, low-latency responses, and multilingual support. After the production-grade use cases from our Voice AI Buildathon, we can't wait to see what builders ship with Hermes.
Cloudflare Cloudflare is the Hosting Partner, taking products from laptop to live in minutes with global deployment, AI Gateway observability, and usage tracking. For an 8-hour buildathon, that's the speed and visibility teams need to reach production
