Technical Cofounder for AI Erotic Chatbot (Fanfinity AI)

Fanfinity AI is a fast-growing AI erotic chatbot platform with 60,000+ users and strong week-over-week traction. Users create, personalize, and chat erotically with immersive AI companions. The platform is live, generating revenue, and scaling quickly. I’m a technical founder myself, but as the product grows, I need to shift more of my focus toward marketing, growth, and strategy. That’s why I’m looking for a technical cofounder who can fully own engineering and long-term technical direction. If you want to join a startup that already has real users, real revenue, and real momentum — this is the moment to step in. Responsibilities: Lead all technical development of the AI companion platform Enhance the core erotic chatbot experience (text, voice, image generation) Scale infrastructure to support rapid user growth Integrate and optimize AI APIs (OpenAI, 11Labs, Stability/HuggingFace, etc.) Own backend architecture (Next.js, Node, Server Actions, RSC, Redis, MongoDB, AWS) Ship fast, experiment, iterate, and solve problems independently Work closely with me on product roadmap and long-term vision What’s already in place: 60,000+ users Recurring revenue Strong brand and accelerating demand Solid acquisition funnel A clear roadmap and a working product already loved by users This role is equity-based and ideal for someone who wants to be a true cofounder in a rapidly growing AI startup — not an idea-stage concept.
