Technology & Development
Software developer at BR-ND People and co-founder of eyay studio (AI-native product studio). Turns questions into working systems: data, software and applications for teams.
Sinyo Koene is a software engineer and co-founder of eyay studio, an AI-native product studio he runs with Ayu Koene. He builds websites, AI agents and custom software for BR-ND People (Amsterdam, B Corp since 2018) and its clients — using AI-powered development to deliver in days what traditionally takes months.
Most developers build what you ask for. Sinyo builds what you need; often before you realize it yourself. Together with his sister Ayu, he runs eyay studio, a design studio for AI apps. He uses AI-powered development to deliver in days what others take months to build. From custom software and data tools to working prototypes: he makes technology accessible for teams that want to experiment and learn.
Sinyo proves you don't need a big team to build big things. One sharp developer with the right tools and a clear idea is enough.
