Boom, a leasing operating system for single family rentals (SFR), announced Tuesday that it has secured $15 million in Series A funding. The company also announced the launch of BoomCRM, an agentic leasing and touring customer relationship management product built on top of the Boom’s existing underwriting engine.
S3 Ventures led the round, with Mischief VC (fund of Plaid CEO Zach Perret) participating. Repeat participation came from venture capital firms Starting Line VC, Company Ventures, and Gilgamesh Ventures.
Founded in 2020 and based in Austin, Texas, Boom bills itself as a financial services infrastructure company for rental operations. It works with property management systems dealing with on-time payments, fraud reduction and revenue growth across the renter lifecycle for SFR, scattered site and manufactured housing (MH) sectors.
“We have been fairly conservative to date on the capital we’ve raised and the capital we’ve spent,” said Rob Whiting, CEO and co-founder at Boom. “We have a strong product market fit and have grown about 8x up until our Series A, and we’ve further grown 3x since the start of the year. This funding will help us accelerate several things, including the launch of this product and several more products after this, as well as growing the engineering team to support that, along with go-to-market efforts. As we primarily play in single-family rentals and manufactured housing, we want to continue to double down in those areas.”
Boom’s existing products are BoomReport, automated rent reporting to incentivize on-time payments, grow revenue, and build resident credit, and BoomScreen, a tenant screening tool to mitigate fraud, increase leasing velocity, and move in best-qualified renters.
Whiting said that most leasing CRMs today are either built multifamily-first or are general-purpose tools such as Salesforce and HubSpot, retrofitted for rentals. EliseAI is the most visible rentals-specific player, recently raising at a $2 billion-plus valuation, and KnockCRM sold to RealPage for several hundred million a few years back. SFR has largely been overlooked by those incumbents, as scattered sites, numerous properties, and diverse ownership structures require different nuances, he added.
“We are different from some of the others in the space that started from the chat experience,” explained Whiting. “We started from compliance and underwriting, and so the way we think about how AI interplays here is that leasing is a high-velocity space and there’s a lot of going on, and these renters are in the market for 30 to 90 days. So teams are increasingly centralizing the process. We’re using AI underneath all of this to power everything from the responses and so forth to the underwriting l of the applicants as well.”
Boom already works with property managers for some of the largest SFR and MH operators, including more than 400 operators and approximately 500,000 units, plus over 25 percent of the top 40 SFR third-party operators and 30 percent of the top 100 largest MH operators.
“Property managers are running on software built to keep the books, not make decisions,” Aaron Perman, general partner at S3 Ventures said in an email. “Boom turns a painful, disjointed rental process into a modern consumer experience, with same-day application answers.”
