Headquartered in Rockefeller Plaza, New York, Thriver will provide alternative solutions for security deposits, helping both renters and property managers conserve resources and manage risks effectively.

Thriver integrates with property management software, enhancing operational efficiency for landlords and property managers.

It allows tenants to pay a reduced amount compared to traditional security deposits, alleviating the financial burden of high upfront move-in costs.

In addition, this product is expected to expedite lease signings, reduce property vacancy periods, and lower risks associated with rent defaults and property damage.

Thriver CEO Matthew Mayberry said: “We’re ideally positioned to expand in this growing market, and by addressing both tenants’ and landlords’ needs, we are confident Thriver will be a game-changer in the rental market.”

In May 2025, United Risk appointed Richard Christofer as president and chief commercial officer.

Formerly with AIG, Guy Carpenter, and Gen Re, Christofer leads the recruitment and acquisition of new underwriting programs while managing the company’s existing business.

He will be based at the corporate headquarters in Rockefeller Centre, New York.
