Real estate data provider Attom is acquiring the assets of a former residential investment firm, a move that aims to expand its technology and artificial intelligence holdings and support scalability for both platforms. 

The merger with Resishares complements Attom's own access to housing data across the country and expands it to accelerate development of enterprise technology products capable of providing granular-level analytics and forecasting for real estate and financial services businesses, the company said. 

"Resishares meaningfully strengthens Attom's competitive moat and further differentiates us in a dynamic market," CEO Rob Barber said in a press release. 

"As we continue to invest aggressively in data, analytics and AI, this acquisition reinforces our long-term competitive advantage," he added.

Resishares was founded in 2020 as an institutional single-family rental acquisition and  management firm driven by its proprietary technology. Its co-founders included former Housecanary executives and leaders from within asset management. 

Thanks to Resishares' AI-backed tools, customers will be able to tap into advanced data science and research findings and combine them with Attom data that covers 158 million U.S. properties. Resishares' technology consists of proprietary home-price and rent forecasts, neighborhood performance data and analytics modeling built to identify local trends, risks and opportunities. 

"This is a natural next chapter for the technology and capabilities we built," Resishares co-founder and former CEO Michael Greene said. "By combining our analytics platform with Attom's data at scale, we're excited to see these tools reach a much broader audience and deliver value across a wide range of use cases."

Financial terms of the deal were not disclosed. 

Mergers in the data technology space

The announcement continues the ongoing wave of mergers and acquisitions that have marked the middle part of this decade, a trend which appears set to continue throughout 2026 as market sluggishness persists during a regulatory environment seen as favorable for M&A approval.  

While much of the attention in 2025 focused on moves by major lenders and servicers, the latter half of the year was also marked by a steady stream of deals among smaller firms.

The first month of 2026 is already opening with two lending-related acquisitions, including a merger announced in mid January between nonbanks Lower and Acopia Home Loans.  

Outside of the lending space, companies in home finance technology and data services like Attom are also joining the list of dealmakers in the latest M&A market. Within originations services, recruitment platform SIMPL passed hands to become a part of mortgage data firm Ingenius last summer.   

The past year saw the sale of multiple loan-origination system platforms, including both Meridianlink and Mortgage Cadence. 

Meanwhile, the most recent quarter saw the purchase of Morvest Capital by global consulting firm Milliman, an acquisition the latter company made to expand its growth and risk analysis of mortgage-servicing rights.
