Rental screening startup 100 today announced that it has acquired Cobblestone Labs Inc., a fraud detection and income verification platform built by former engineers from corporate card company Ramp Business Corp., in a deal that folds an artificial intelligence-native underwriting engine into 100’s rental screening platform.
Terms of the acquisition were not disclosed. As part of the deal, Cobblestone co-founders Jason Scharff and Jack Mastrangelo will join 100 as strategic advisers.
Founded in 2023 and based in New York, Cobblestone offers software that helps institutional landlords reduce delinquency and catch fraud during the leasing process. The platform combines application data with an income verification and fraud detection system aimed at identity fraud, income fraud and synthetic identities across residential real estate.
Its founding team met at Ramp before turning to property technology. Cobblestone went through Y Combinator’s Winter 2023 batch and counts the accelerator among its backers.
