We help companies get mentioned in ChatGPT by rebuilding the internet for AI agents.

Our product helps companies like NVIDIA, Rho, and Exa get cited by ChatGPT, Gemini, and Perplexity.

You’ll join as a founding engineer to design experiments and systems that uncover how AI agents crawl, retrieve, and cite the web.

You might be a fit if you’ve:

• Worked with LLMs at the infrastructure or evaluation level (OpenAI, Anthropic, Perplexity, LangChain, etc.)

• Or built edge systems at Cloudflare, Vercel, or Netlify and want to apply that expertise to AI agents

• Shipped production systems in Next.js, TypeScript, or Go

• Built or debugged telemetry and routing pipelines

• Are curious about how LLMs choose what to see, cite, and trust
