ApartmentIQ, a real-time market intelligence and AI platform for the multifamily industry, has secured a $25 million follow-on investment from Susquehanna Growth Equity. The funding extends a relationship that began in 2021, when SGE led the company’s $22.5 million Series B while it operated under the Rentable brand. The new capital will support ApartmentIQ’s continued expansion across market intelligence, revenue management, automated property marketing, and AI-powered products.
Expanding Beyond the Rentable Marketplace
ApartmentIQ has undergone a significant transformation from its origins as a consumer-focused apartment marketplace into a broader technology platform for multifamily operators. The company now supports more than 1,500 portfolios representing approximately 8 million customer units, including 70 percent of the National Multifamily Housing Council’s Top 50 operators. Its growth has been built around real-time public data designed to help property owners and managers understand market conditions, improve pricing decisions, and automate operational workflows.
At the center of the platform is ApartmentIQ’s automated market survey product, which delivers daily, unit-level pricing and availability intelligence derived entirely from publicly available information. The system is designed to replace manual market survey processes that multifamily teams have traditionally used to track competitors and assess pricing conditions. ApartmentIQ positions this real-time data foundation as the basis for a broader suite of tools serving operators, investors, and developers.
Broadening the Product Portfolio
ApartmentIQ recently expanded its offering with Explore Pro and Daylight, two products built on the company’s market data infrastructure. Explore Pro provides real-time market intelligence intended to help operators, investors, and developers identify acquisition, development, redevelopment, and competitive opportunities. Daylight is an AI-powered revenue management platform trained on nearly six years of daily market data covering 40 million units.
The company said both Explore Pro and Daylight are currently tracking to surpass 1 million customer units during their first year. Daylight is designed to provide predictive revenue management capabilities while maintaining transparency around the market data underlying its recommendations. The growth of these products reflects ApartmentIQ’s broader push to extend its role beyond market surveys and provide a wider range of decision-making tools to multifamily operators.
Advancing Agentic AI With MavenAI
ApartmentIQ has also launched MavenAI, an AI-powered marketing agent designed to automate workflows that property teams have historically managed manually. The platform handles functions including Google Business Profile updates, social publishing, and listing management across fragmented marketing channels. ApartmentIQ said MavenAI currently powers more than 10,000 properties and has already saved multifamily teams tens of thousands of hours of manual work.
MavenAI represents the company’s first major expansion into agentic AI, with software designed to take action on behalf of operators rather than only surface market information. ApartmentIQ is positioning the product to support property teams as renter discovery increasingly shifts toward generative engine optimization and AI-driven search experiences. The company plans to use part of the new funding to accelerate investment in MavenAI and develop additional AI-powered products.
Supporting the Next Phase of Growth
The $25 million investment will also support continued hiring across ApartmentIQ’s engineering, data, product, and go-to-market teams. Co-founder and CEO Alec Slocum said the company has evolved considerably since SGE’s original investment, with its focus moving toward helping multifamily operators make more predictive decisions and automate manual work. He added that the new capital will accelerate ApartmentIQ’s vision of building a broader multifamily platform powered by real-time public data and AI.
SGE Managing Director Josh Elser said ApartmentIQ has consistently translated product development into growing adoption across the multifamily industry. He highlighted the company’s expansion across real-time market intelligence, revenue management, and marketing automation as evidence of a platform becoming increasingly important to operators and owners. SGE said it will continue supporting ApartmentIQ as the company scales its technology and customer reach.
The follow-on investment gives ApartmentIQ additional resources to expand a platform that now spans market intelligence, revenue management, AI-powered marketing, and operational automation. With 8 million customer units, more than 1,500 portfolios, and growing adoption of products such as Explore Pro, Daylight, and MavenAI, the company is entering its next phase with a significantly broader offering than its former Rentable marketplace. Founded in 2013 and also backed by 4490 Ventures and Flyover Capital, ApartmentIQ will use the new funding to deepen its product capabilities and continue expanding across the multifamily sector.
