Indexed description

We’re building an AI productivity SaaS startup, organized as a cooperative (shared ownership based on real contribution).

We’re looking for an additional Founder focused on Technology & Engineering (CTO track).

We do not expect you to build the product, as we have already done so, but we do expect you to be hands-on.

This is a founder role, not a freelance, advisory, or employee position.


Important upfront

  • There is no fixed cash compensation at the start
  • Cash payment depends entirely on revenue or external funding
  • You do not have to contribute any money, other cofounders have contributed enough and already cover expenses, especially product development
  • Once revenue or funding comes in, cash is shared among all founders


What you’ll do

  • Technology & Architecture (core focus)
  • Own the technical vision and architecture of the product
  • Guide decisions around AI integration, scalability, and system design
  • Ensure high code quality, maintainability, and performance
  • Collaborate closely with product & design to deliver a clean, fast, intuitive UX


Engineering Leadership & Process

  • Work with an established full development team in India
  • Coordinate with the team rather than replacing them
  • Translate product goals into clear technical execution


You

  • Solid background in React & Next.js
  • Comfortable with AI-driven products (LLMs, AI workflows, integrations)
  • Very familiar with project management methodologies
  • You want to be a real founder, not a contractor or “CTO-for-hire”


Cooperative & Founder Setup

  • Everyone works under the same cooperative founder contract
  • Shares are earned based on contribution, not titles
  • No special treatment for any one founder
  • Ownership, responsibility, and upside are shared


Our Team

  • International founding team across Germany, Switzerland, India
  • Many years experience, successful consultant & startup experience
  • Strong technical execution already in place


This is great for you if…

  • You want to be a founder of an AI SaaS
  • You’re fine with low or no cash initially
  • You like shared responsibility in a strong founding team
