A new proptech platform has launched nationwide to expand housing access and strengthen property performance. Founded by real estate professionals, Cosign is a third-party guarantor that uses advanced data modeling to help more renters qualify for apartments while protecting owners from payment defaults and vacancy losses.
“More than 40% of renters are denied their first-choice apartment due to qualification barriers,” said Zach Schofel, founder and CEO of Cosign and co-managing partner at Eastman Residential, which owns over 2,500 units nationwide. “Cosign was built by real estate owners and managers for real estate owners and managers. We’re using data and experience to open doors for rents while directly improving owners’ bottom lines.”
Cosign had a yearlong beta across 150,000 units, delivering a 90% approval rate for renters and zero partner churn. The platform works across all asset types—from affordable housing to Class A new construction.
“Cosign is bridging a gap that’s held the rental market back for decades,” Schofel said. “It’s a rare solution that delivers value to both renters and landlords. We’re expanding housing access while improving the financial health of properties nationwide.”
Cosign celebrated its official launch last week in Dallas, with over 250 owners, operators, and developers to discuss today’s housing market as well as technology and proptech innovation. According to the firm, it already is working with National Multifamily Housing Council top 50 owners and operators and continues to scale its partnerships.
“Our mission is to expand housing access by empowering owners to safely approve qualified renters who might otherwise be denied, without sacrificing compliance or financial security,” Schofel added.
