About

Hi, I’m Roy.

There’s never one right word for a person. For me it takes a few: ENTJ, ADHD, and above all someone who loves engineering for the making, and the entrepreneur’s life for the risk.

I spent more than 10 years building products — chances are you’ve used one, and I hope you enjoyed it. Along the way I was named to Forbes 30 Under 30 in 2021. These days that energy goes into LUDENS AI, a robot that keeps you company.

Beyond work I keep a small world of my own. Photography, mostly.
