About arjunnarayan

I'm Arjun Narayan and I work at Amplify, a VC firm. I'm the co-founder (and former CEO) of Materialize (http://www.materialize.com). Previously, I was an engineer working on CockroachDB (http://www.cockroachlabs.com). Before that, I was a PhD student at the University of Pennsylvania, where my research was on differential privacy, distributed systems, and networks.

My interests are databases, operating systems, distributed systems, networks, new hardware, and security.
