Marc Rosa
Head of Product
I'm a product leader who helps early products grow into enduring companies.
Most recently, I was Head of Product at Thread. We turned a single product into an AI platform — growing revenue 10x, raising a Series A, and becoming category leader in the MSP market.
Before that, I led product at Zipwhip leading to its acquisition by Twilio (TWLO).
I love building opinionated software — products with a clear point of view — that are resilient enough to scale.
