Boom, the leasing operating system for property management, has raised $15m in a Series A funding round and used the announcement to launch BoomCRM, a new leasing tool built around underwriting intelligence.
The round was led by S3 Ventures, with participation from Mischief VC, alongside continued backing from existing investors Starting Line VC, Gilgamesh Ventures and Company Ventures.
BoomCRM answers incoming calls, qualifies prospective tenants and arranges property tours, and the company positions it as the first leasing customer relationship management platform built from the ground up on underwriting data rather than having screening added later.
Boom already provides screening services to more than 400 property operators overseeing in excess of 500,000 units, with clients including AMH, Roots Management, Marketplace Homes, Saratoga Group, On Q Property Management and RENU Property Management.
The firm also works with more than a quarter of the companies on Peter Lohmann’s list of the largest third-party single family management businesses, as well as, by its own analysis, 100 of the largest manufactured housing operators ranked by homesite count. Boom is additionally named as the preferred screening partner for ManageAmerica and the Keyrenter franchise network. BoomCRM took 16 months to develop and was built in close collaboration with operators who already relied on Boom for screening decisions.
Boom argues that existing leasing CRMs generally fall into three categories: platforms designed primarily for multifamily housing, broader tools such as Salesforce and HubSpot adapted for rental use, and showing-focused systems that serve scattered properties but run on older chatbot-style logic, with screening bolted on afterwards.
BoomCRM differentiates itself by running screening natively within the same system, so information gathered during pre-screening, including identity verification, carries straight into the application without needing to be re-entered or paid for twice. The platform is designed around scattered-site portfolios as the norm rather than an exception, supporting self-showings as standard, allowing a single operator to manage homes for multiple owners, and scheduling tours around an agent’s real drive time and home base.
It is powered by current agentic AI models rather than decision-tree systems, and comes with open API access so property managers can move data between other platforms they use.
Boom CEO Rob Whiting said, “Before long, every platform will have an agent that answers the call and books the tour. That part is table stakes. What’s hard to replicate is the intelligence underneath, knowing who will actually qualify. Everyone else is working toward that decision. We started there, and built the front door already knowing who belongs in the room.”
Endeavor Communities principal Ryan Smith said, “Our biggest problem was never lead volume, it was visibility. Boom’s AI Leasing Agent handled close to 200 calls last month, 20% of them after hours, and gave my team back more than 75 hours. They spend their days turning qualified prospects into residents instead of chasing callbacks.”
