Polytech

Polytech, a fintech product aimed at a global user base, was founded and independently developed by Eray Pişkin. It reached 2,000+ users and $150,000+ in volume worldwide.

He was responsible for the whole of it, from the product idea and strategy through software architecture, development, infrastructure, deployment, growth and operations.

An acquisition offer of roughly $40,000 came in for the project. He turned it down.

He discontinued Polytech in May 2026.
