Hey, I'm Nicolai
I like building from the annoying parts of real life.
Finance, tax prep, inboxes, documents, work, engineering systems. Lately I've been turning those into agent-native products and the infra behind them.
jup, not a single stock photo in sight!
About me
I lead engineering teams. Over the last decade I've built and shipped products at startups, mostly turning chaos into something that works.
Lately I've been building tools around the problems I keep running into myself: money, taxes, work, messages, documents, and the systems around building software.
Based in Berlin. I ride motorcycles and just finished building a house. Always open to interesting challenges.
What people say
"Without Nicolai Nunc would look very different today. His unique value, is not his engineering knowledge, but the ability to quickly understand customer demands, user journeys, and sales cycles."
Dariush Wahdany — Managing Director, Nunc.immo
"Nicolai joined when Maon was not much more than an idea. He took my vision for the product and delivered the full technological implementation, which is still the foundation to this day."
Mihail Ketov — Managing Director, Maon
