He Put the Apartment Tour Inside the Browser
Wojciech Kalembasa turned a mortgage broker's frustration with flat property listings into a visual-media company, a proptech platform, and a 2025 acquisition by Yardi. The useful part of his story is the sequence: listen closely, build the service, then turn the repeated work into software.
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.
