Geoff Segal

Geoff Segal is currently the Co-Founder of FullSeam, an early-stage technology startup participating in the Y Combinator Winter 2026 batch. Prior to launching this new venture, he co-founded TaxProper during the Y Combinator Summer 2019 batch, where he developed a specialized property tax software platform. Under his operational direction, the business scaled to become a leading business-to-business technology provider for institutional real estate investors managing large property portfolios. In 2022, Segal successfully guided TaxProper through a strategic acquisition by Opendoor, a major publicly traded real estate enterprise listed on the NASDAQ exchange. Following this successful exit, he transitioned to his current enterprise software project to continue addressing inefficiencies within the broader property technology sector. As a two-time Y Combinator founder, his professional background centers on building scalable business-to-business software solutions for the institutional real estate market.
