Head of Product

Marc Anthony Rosa

I lead product organizations and help early startups become scalable businesses.

Most recently, I was Head of Product at Thread, joining at seed stage and helping grow the company to Series A. We transformed a point solution into a multi-product platform, drove 10× revenue growth, and became a category leader in the MSP market.

Previously, I led product at Zipwhip through its rapid 2020 growth and acquisition by Twilio.

My focus is on building opinionated software: products with a clear point of view that solve real problems and hold up as they scale.
