Code with character

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.

  • Building instead of meeting – Sinyo codes websites, AI agents and tools at a speed that makes most agencies dizzy. No PowerPoints about possibilities; working products.
  • Technology with a human core – He builds systems that turn questions into answers. From the BR-ND People website to the whitepaper generator: everything coded, nothing drag-and-drop.
  • Creative DNA – At seven years old, he drew the winning BR-ND logo: a red line ending in a beating heart. Twenty years later, he builds the digital systems that keep that same heart beating.

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.

Curious what technology can do for your organization? Sinyo would rather build it than talk about it.
