Clau.com, formerly known as Flat.mx, is a Mexican proptech company that operates a comprehensive real estate marketplace and service platform. Founded in 2019 by Bernardo Cordero and Victor Noguera, the company was originally launched as an instant buyer (iBuyer) offering quick home purchases, but pivoted in 2024 to become a traditional real estate portal with integrated financial services. The company is headquartered in Miguel Hidalgo, Mexico City, and is backed by Y Combinator (Summer 2020 cohort) and prominent investors including Anthemis, 500 Startups, Hi Ventures, and Expa, having raised approximately $84.8 million in venture capital funding. The platform currently features around 80,000 property listings nationwide, with plans to expand to 200,000 verified listings. Clau operates as a multi-sided marketplace connecting buyers, sellers, and real estate agents through a tiered subscription model. Beyond property listings, the company provides a CRM system for real estate brokers to manage client relationships and transactions. A key differentiator is Clau's integrated financial services component, which includes mortgage brokerage services through its 2023 acquisition of Hipoteca Genial, a digital mortgage advisory platform founded in 2017. The company also acquired Intelimétrica in February 2023, a real estate data analytics firm that provides market intelligence, property valuation tools, and price mapping capabilities. This data layer enables Clau to offer sophisticated pricing analytics to both consumers and professionals. The company initially focused on major metropolitan areas including Mexico City, Monterrey, and Guadalajara, but is now expanding to secondary markets across Mexico. Clau employs approximately 144 people and competes with established players like Inmuebles24 (owned by Brazilian unicorn QuintoAndar) and Lamudi (owned by Lifull Connect). The company represents a hybrid proptech-fintech model, combining marketplace technology with mortgage financing services to address pain points in Mexico's traditionally fragmented real estate transaction process.
