About Us

We’re a stealth-mode consumer AI startup with a bold mission: to put an AI teammate in every pocket. Our vision is to build a mobile app that combines advanced LLM reasoning (orchestration layer) with deep API / MCP integrations to automate end-to-end workflows and tasks. We’re at the ground floor of a transformative opportunity to redefine how people interact with AI in their daily lives.

We’re seeking a visionary Founding CTO / Technical Co-Founder to join our journey, shape our technical strategy, and build a unicorn company with multi-billion-dollar potential. This is an opportunity to create something ground-breaking alongside a passionate founder, with founder-level equity reflecting the early stage of our venture.

About You

We’re looking for a driven, creative, and ambitious individual who thrives in a fast-paced startup environment. You’re not just a coder—you’re a builder with a mindset geared toward creating a lasting company. If the following resonates with you, we’d love to hear from you:

• Entrepreneurial Spirit: You’re motivated by the challenge of building a multi-billion-dollar business from scratch and see this as your life’s work.
• Creative Problem-Solver: You challenge the status quo, think outside the box, and devise innovative solutions to complex problems.
• Passionate Builder: You code for fun, tinker with side projects in your spare time, and are eager to join a unicorn-caliber project.
• Big-Picture Thinker: You’re excited to contribute to recruiting, marketing, and fundraising efforts, even if coding remains your core strength.
• Resilient & Agile: You can rapidly prototype MVPs, run experiments, learn from failures, and iterate without losing momentum.
• Effective Communicator: You articulate ideas clearly and collaborate seamlessly with technical and non-technical stakeholders.
• Open to re-locate to the US: If needed for the success of the company.

Technical Skills

We’re seeking a versatile technical co-founder with as many of the following skills as possible,

• Advanced AI/ML Development: Deep experience building and deploying AI products, particularly with large language models (LLMs).
• Full-Stack Development for Consumer Applications: Proficiency in mobile and web app development.
• Rapid Prototyping & Iteration: Ability to build and iterate MVPs quickly, leveraging AI coding to 10x productivity.
• Bonus: Prior work at leading tech companies or early-stage AI startups.

This role starts part-time to ensure alignment in vision, working style, and compatibility through a short-term project. Success here will transition into a full-time commitment with founder-level equity.

Join us in putting an AI teammate in every pocket. Let’s build something extraordinary together!
