Flexmls

What Flexmls does

Flexmls is the flagship Multiple Listing Service (MLS) platform developed and operated by FBS, a privately held, 100% employee-owned software company headquartered in Fargo, North Dakota. Founded in 1984, FBS has built and maintained Flexmls for over 40 years as the core product within a broader real estate software suite that includes Flexmls IDX (Internet Data Exchange), Launch Dashboard (agent and broker websites), Spark API (developer data access), Flexmls Pro mobile apps (iOS and Android), Flexmls Portal (consumer-facing property search), and Flexmls Academy (training and enablement). The platform is a cloud-based, mobile-first MLS system used by 331k active subscribers across MLS organizations and real estate brokerages, processing 3.2 million photo uploads per month and supporting tens of thousands of monthly home sale transactions through the system.

Technically, Flexmls is built around a centralized MLS data store with feature parity across web, iOS, Android, and mobile web clients, and exposes its data externally through the Spark API and a Model Context Protocol (MCP) server. Recent product investment has focused on AI capabilities: Auto Assistant+ uses computer vision to detect features in listing photos and generative AI to produce listing remarks and photo captions, while the MCP server enables natural-language querying of market statistics and listings through AI assistants such as Claude and ChatGPT.

Flexmls generates revenue through subscription-based licensing sold via enterprise field sales to MLS organizations and real estate associations, which then provision platform access to their member agents. Pricing is quote-based, not publicly disclosed, and structured as annual SaaS contracts with multi-year potential. Customer segments are MLS administrators (primary, enterprise buyers), real estate agents (primary end users), and real estate brokers (secondary, office-level users). Go-to-market combines direct enterprise sales with a channel model in which MLS associations act as distribution partners.
