Mont Haus International Realty and AnyProp Partner to Power MLS Data Across Colorado's Mountain Markets

AnyProp supplies normalized MLS data, a unified API, and compliance support for Mont Haus's newly launched website, connecting listings from Aspen and Vail to Telluride, Steamboat Springs, and the Front Range

ASPEN, Colo., Oct. 29, 2026 /PRNewswire/ -- Mont Haus International Realty, the Aspen-born luxury brokerage with offices in Aspen and Vail, has partnered with AnyProp, a data services and MLS compliance platform, to power the listing data behind its newly launched website, monthaus.com. AnyProp, co-founded by former Zillow CEO Spencer Rascoff and veteran proptech founder and engineer Lawrence Zhou, delivers MLS listing data from each of the markets Mont Haus serves through a single normalized API, and manages the licensing and compliance work required by each MLS organization.

"We are so grateful to the team at AnyProp for not only supplying the data we need but also for making the integration process easy, clear, and totally seamless. Our MLS-dependent proprietary web tools are a key part of our rapid growth as a new brokerage, and our agents across Colorado count on Mont Haus to provide trusted, compliant listing data. We could not have achieved this success so quickly without AnyProp's reliable API and nimble responsiveness," said Nikki Boxer, Creative Director at Mont Haus, who led the launch of the brokerage's new website.

Mont Haus's agents work across eight Colorado regions: the Roaring Fork Valley, the Vail Valley, Summit County, Routt County, Lake County, the Gunnison Valley, Southwest Colorado and the Front Range. Those communities fall under several different MLS organizations, including ReColorado, Altitude MLS, Telluride Association of Realtors, Vail Multi-List Service, Aspen Glenwood MLS, elevateMLS, and Colorado Real Estate Network. Each has its own data feed, licensing agreement, display rules, and approval process.

AnyProp serves as the single point of coordination for that work. It handles MLS onboarding and IDX data licensing, keeps Mont Haus current with each organization's compliance requirements, and normalizes the separate listing feeds into one RESO-compliant API. The result is one integration behind the entire site rather than a separate build for every board.

"There are more than 480 MLS data feeds across the U.S. and Canada, each with its own rules, engineering needs, association relationships, permitted uses, and compliance requirements. That's tricky terrain for any brokerage to navigate alone. We've mapped it already, so our clients can move into new markets without the friction," said Lawrence Zhou, Co-Founder and Technical Architect of AnyProp.

The new monthaus.com lets visitors search every listing in the markets Mont Haus serves, explore nearly 40 mountain and Front Range communities, and browse the brokerage's exclusive listings, new development projects, and curated luxury rentals. Featured exclusives on the site include estates in Aspen listed at up to $65 million.

AnyProp works with brokerages, proptech platforms, investors, financial institutions and specialty marketplaces, providing a unified MLS data API, normalized property data, verified media, location data and compliance tools across hundreds of U.S. real estate markets.
