Jan Senderek is Co-Founder and CEO at Roma (YC F26), an AI-powered productivity app that reinvents the to-do list by doing the work for you.

Jan, a German entrepreneur, earned his master's degree in technology entrepreneurship at University College London (UCL) before co-founding his first startup, Popset, which evolved into Loom (YC W12).

Jan is a product founder with 15+ years of experience building consumer products, and brings rare serial founder credibility having successfully exited two YC-backed companies.

Jan co-founded Loom (YC W12), a cloud photo storage app acquired by Dropbox in 2014, after which he served as a Product Manager at Dropbox, launching the document scanner and leading mobile apps for Photos.

Roma, backed by Y Combinator's Fall 2026 batch, is reinventing the original productivity tool by combining task management with AI automation, building on Jan's proven track record of two successful acquisitions.
