Propexo
Propexo is a Boston-based proptech startup building the unified API and data platform for multifamily real estate. Often described as 'Plaid for commercial real estate,' Propexo lets software developers and property operators connect to 130+ property management systems - like Yardi, RealPage, AppFolio, Entrata, and Buildium - through a single, normalized API and no-code sync tool. What once took teams of engineers months to build, Propexo delivers in days, with standardized data models, webhooks, and enterprise-grade security. Founded in 2022 and a Y Combinator W2023 alum, it raised a $3.3M seed round led by Prudence in October 2023.
Remen Okoruwa
Remen Okoruwa is the co-founder and CEO of Propexo, a Y Combinator-backed Boston startup building a unified API for property management software. Pitched as 'Plaid for commercial real estate,' Propexo lets engineers connect to legacy systems like Yardi, RealPage and Entrata in days instead of months. An Iowa kid who studied engineering at Harvard, Remen took a winding road through McKinsey, a churn-fighting data startup, product leadership at HubSpot, and a rent-payments venture before landing on the unglamorous but enormous problem of moving property data. He now powers integrations behind more than half of the NMHC Top 15 managers.
