Solid Earth

What Solid Earth does

Solid Earth is a privately held U.S. software company that provides identity management and single sign-on (SSO) solutions for Multiple Listing Services (MLSs) and REALTOR Associations. Founded in 1999 and wholly owned by TRIBUS Group (acquired October 2020), the company serves more than 425,000 real estate professionals across over 100 MLS customers nationwide. Its platform consolidates member identity, authentication, billing, and access to third-party MLS vendor tools into a unified dashboard, with distribution spanning flagship enterprise customers (Miami REALTORS, ARMLS, BeachesMLS, RMLS, Heartland MLS) and a long tail of mid-market MLSs and associations.

The company's technology stack is built on FIDO2 WebAuthn standards with biometric passkey authentication (Face ID, Touch ID, fingerprint), adaptive multi-factor authentication, and a proprietary single-record-per-human identity system called EZID. The core product portfolio comprises the SSO Dashboard, Secure Access IdP (branded as Ezement/Ezecure), Public Search Portals, MLS and Association Sites, an integrated billing system, and an in-house advertising division launched in February 2026. Solid Earth maintains direct integrations with all major MLS vendor platforms — Matrix, Paragon, Flexmls, ConnectMLS, Rapattoni MLS, and NAVICA — enabling deployment across heterogeneous MLS environments. In November 2023, the company completed a multi-million dollar platform rewrite that underpinned rapid commercial scaling beginning in mid-2024.

Solid Earth's revenue model combines subscription licensing (priced annually and scaling with member seat count, negotiated at the enterprise level) with a non-dues advertising stream connecting vetted brands to the 425,000+ user audience. Go-to-market is enterprise sales-led, targeting CEO/CTO/COO-level decision-makers at MLS and Association organizations, supplemented by a NAVICA channel partnership reaching nearly 100 additional MLS customers and by direct participation in industry events (RESO, CMLS, Inman). Distribution is domestic-only (United States); the firmographic reference to Canada is not corroborated by customer or operational evidence in the input data.

Revenue model

1. Subscription Licensing (MLS/Association): MLS organizations and REALTOR Associations pay subscription fees for access to the Solid Earth platform including SSO dashboards, IdP, and identity management tools. Pricing scales with number of member seats/organizations served. Solid Earth has crossed 425,000 users across its ecosystem, with annual revenue per member increasing approximately 1% through non-dues advertising revenue.
2. Non-Dues Advertising Revenue: In-house advertising sales division connects vetted national brands (fintech, insurance, prop-tech) with the 425,000+ real estate professionals in the Solid Earth ecosystem. Ads are embedded natively within the SSO dashboard and MLS website properties. MLS partners receive a share of ad revenue without increasing subscriber fees.

Scale indicators11 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Okta: Leading cloud identity and SSO provider for enterprises. Highly comparable on the underlying IdP/SSO/MFA technology stack that Solid Earth delivers, but Okta serves all verticals broadly and lacks Solid Earth's MLS-specific integrations, billing, and advertising modules.
• Microsoft Entra ID (Azure Active Directory): Microsoft's enterprise identity and SSO platform. A natural alternative MLS organizations could adopt, especially those already in the Microsoft ecosystem; competes with Solid Earth's IdP/SSO positioning but lacks the MLS-vendor integrations and EZID identity model.
• Auth0 (Okta): Developer-focused identity platform offering SSO, MFA, and adaptive authentication APIs. Comparable to Solid Earth's Ezement platform on core authentication/identity capabilities, but Auth0 is a horizontal offering without MLS-domain workflows or front-end of choice integrations.
• OneLogin: Cloud-based identity and SSO provider with SSO, MFA, and user provisioning. Closely comparable on the SSO/IdP technology axis that Solid Earth sells, though OneLogin is a horizontal SaaS without the MLS/Association-specific vertical feature set.
• Black Knight / ICE Mortgage Technology (Paragon): Large real estate and mortgage technology incumbent that owns the Paragon MLS platform. Comparable as an integration partner today and as a strategic risk: a player with the scale and engineering resources to offer identity and SSO as part of its broader MLS suite.
• CoreLogic (Matrix MLS): Major MLS platform vendor (Matrix) and broad real estate data/technology incumbent. Comparable as both a current Solid Earth integration partner and a potential vertical-integration threat that could embed native IdP/SSO into the Matrix MLS platform.

Emerging players

• iHomefinder: IDX and MLS consumer search provider for real estate websites. Comparable on the consumer-facing MLS search portal product line that Solid Earth offers, although iHomefinder operates primarily at the agent/brokerage layer rather than the MLS/Association layer.
• Showcase IDX: IDX and consumer search platform serving real estate agents and brokerages. Overlaps with Solid Earth's public search portal and Displet sub-brand on the agent-facing side of the MLS ecosystem, though Showcase IDX is a smaller, IDX-focused player.

Direct peers

• FBS (Flexmls): MLS software vendor behind the Flexmls platform and the company that previously owned Solid Earth (acquired it in 2017, divested in 2020). Directly comparable as a competing MLS platform ecosystem that competes for the same MLS technology budget.

Others

• RentSpree: Rental technology provider serving MLSs, brokerages, and agents with tenant screening and rental listings. Adjacent ecosystem partner (co-sponsor at RESO conferences) rather than a direct competitor, but operates in the same MLS-association technology buying center.
