Dmytro Dzhulgakov Learned to Race Code. Now He Races AI Models.

Rentberry
Rentberry is a San Francisco-based proptech company building an end-to-end, AI-powered rental ecosystem that lets tenants and landlords handle the entire rental lifecycle online - from search, virtual tours, applications and automated tenant screening, to digital lease signing, rent collection and ongoing maintenance. Founded in 2015 by Ukrainian entrepreneurs after a frustrating San Francisco apartment hunt, the platform now spans roughly 90 countries and uses AI agents to analyze listings, generate property descriptions, negotiate pricing and coordinate move-in services. The company has expanded into a chain of furnished modular homes and is preparing for a planned public listing under the NASDAQ ticker RNTB.
