Mark Cheli

I'm Mark Cheli. I live in Ashland, MA and work at PTC on Onshape, the SaaS-native CAD platform PTC acquired in 2019. Before Onshape I worked across PTC's IoT (ThingWorx), CAD (Creo), PLM (Windchill), and Academic Programs groups.

I'm the director of Onshape's Product Operations & Strategy team. The work is a mix of product-led growth, internal AI adoption, product analytics, the operating cadence the org runs on, and full-stack code on early-stage product initiatives.
