Book a callThe human behind Node and Mass
Ten years in product taught me one thing: great teams rarely fail from building badly. They fail from building the wrong thing.
So I started Node and Mass to do it differently.
Method
A clickable prototype in front of real users within days. Evidence decides what gets built, not opinions. Then we build it fast.
People
Designers and engineers from some of the best product teams in the world. The people you meet are the people who build it.

I angel invest in FemTech, DeepTech and FinTech. Building something cool? Hit me up.
