What Maris does

Mid America Regional Information Services, Inc. (dba MARIS) is a REALTOR-owned Multiple Listing Service (MLS) headquartered in St. Louis, Missouri, serving real estate professionals across Missouri and Illinois. Founded in 1980 (also referenced as 1995 in some materials), MARIS provides its 15,000+ subscribers — including REALTORS, brokers, appraisers, and inspectors — with access to property listing data, market intelligence, and cooperative transaction infrastructure covering 130+ counties. The organization is a member-owned cooperative governed by a board of broker leaders and required to comply with NAR MLS policies, including the Clear Cooperation Policy. Its CEO is Cameron Paine, who joined in 2017 after leadership roles at Connecticut MLS and the Naples Area Board of REALTORS.

MARIS's core product is Matrix MLS (provided by CoreLogic), a web and mobile-accessible listing platform offering search, listing management, client portals, automated emails, CMAs, and IDX/VOW syndication. The platform has been upgraded to "Matrix X" (January 2021) featuring modernized navigation, InRIX Drive Time, concierge map views, and consolidated settings. MARIS has built an integrated ecosystem of complementary products including Realtors Property Resource (RPR) for property analytics and valuations, Realist for public records, ShowingTime for showing scheduling, Homesnap Pro for mobile MLS access (with predictive "Likelihood to List" analytics), Remine for virtual open houses, AdBuilder for property marketing, and Matrix IDX/VOW for website syndication. Recent additions include Photographer Access (2025) and the upcoming Seller Approved Marketing (SAM) policy framework (August 2026) replacing Office Exclusive.

MARIS operates as a member cooperative generating revenue through quarterly subscriber fees ($120/quarter for licensed agents and brokers; $25/quarter for unlicensed/waiver administrators), plus application fees ($50), new office participation fees ($250), and ancillary administrative fees for late payments, reconnection, inspector registration, duplicate listings, and data entry. Distribution is channeled through 14 local REALTOR associations that serve as the primary member acquisition gateway. The firm invests in education programs (Spotlight Webinars, New Member Orientation, in-person classes at member offices with 10-person minimums) and industry events, reporting record growth in May 2025 and launching a Broker Profit Sharing program in March 2025.

Direct peers

• Midwest Real Estate Data (MRED): MRED is the largest MLS in Illinois and the Midwest, serving the greater Chicago area. It directly competes with MARIS for REALTOR associations and broker subscriptions across Illinois, and operates a similar cooperative structure with comparable listing search, Matrix-based platforms, and integration ecosystems. Geographic overlap makes it MARIS's closest head-to-head peer.
• Heartland MLS (HMLS): Heartland MLS is a REALTOR-owned MLS covering the Kansas City metropolitan area and surrounding Missouri/Kansas counties. It shares membership economics, multiple state coverage, association partnership structure, and serves a complementary Midwest footprint adjacent to MARIS.
• Bright MLS: Bright MLS is one of the largest REALTOR-owned MLSs in the U.S., serving multiple Mid-Atlantic states. It provides a benchmark for how multi-state MLS consolidation operates at scale and competes for broker mindshare and vendor partnerships that MARIS also depends on.
• NorthStar MLS: NorthStar MLS is a REALTOR-owned MLS serving Minnesota and western Wisconsin. Comparable cooperative structure, NAR policy compliance, Matrix-style platform, and multi-jurisdiction coverage make it a like-for-like operational and governance benchmark for MARIS.
• Stellar MLS: Stellar MLS is a large REALTOR-owned MLS serving Florida. It provides a model for member services, recurring subscriber fee monetization, and technology partnerships at meaningful scale, comparable in business model to MARIS though larger and single-state.
• REcolorado: REcolorado is the REALTOR-owned MLS serving Colorado. It is a similarly structured cooperative MLS with comparable subscription model, listing tools, and integrations, serving as a useful scale and operating benchmark for MARIS.
• California Regional MLS (CRMLS): CRMLS is the largest MLS in the U.S., formed through consolidation of multiple California regional MLSs. It exemplifies the roll-up strategy MARIS previously executed with SIRMLS and demonstrates the scale a multi-region cooperative MLS can achieve.

Broad incumbents

• CoreLogic: CoreLogic is MARIS's core technology partner, providing the Matrix MLS platform that powers MARIS's listing service. As an incumbent property data and analytics vendor, CoreLogic shapes the platform capabilities MARIS can offer and represents both a critical relationship and a key dependency.
• Zillow Group: Zillow Group operates a major consumer-facing real estate platform that depends on and competes with the MLS ecosystem. While not a direct cooperative MLS peer, Zillow influences listing distribution economics, consumer search behavior, and policy debates that directly affect MLS organizations like MARIS.
• realtor.com (Move, Inc.): realtor.com is operated as an NAR-affiliated consumer platform that relies on cooperative MLS listing feeds. It represents both a key syndication destination for MLS listing data and a broader industry influence on cooperative MLS economics and policy.
