In Latin America's complex and unequal housing market, La Haus has emerged as a transformative force, revolutionizing how people buy and sell homes across the region. Founded by Jerónimo and Tomás Uribe in 2020, and backed by investors including Jeff Bezos, La Haus has facilitated over $1B in gross housing sales through its digital-first platform.

The company's mission to make home buying as seamless as "looking for their next flight at delta.com" led them to explore cutting-edge AI solutions to enhance their customer experience and sales process.

The Challenge: Balancing AI Innovation with Customer Experience

For La Haus, the challenge wasn't simply implementing AI—it was about creating truly effective digital sales agents that could work alongside human associates throughout the complex home buying journey.

As La Haus scaled its operations across LATAM, they encountered significant hurdles with their initial AI implementation:

  • Hallucination issues that damaged customer trust and complicated the sales process
  • Latency problems that created frustrating user experiences when attempting to address hallucinations
  • Low conversion rates from website visitors to scheduled property visits

The Solution: Partnering with Collinear AI

La Haus found their solution in Collinear's AI alignment platform. Recognizing the need for specialized AI capabilities that could handle the nuances of real estate transactions in Spanish-language markets, La Haus and Collinear collaborated on two specific areas:

  • Real Estate Sandbox Environment: Collinear deployed a domain-specific evaluation environment that scored AI responses for clarity, correctness, and conversational effectiveness inside real estate workflows. This allowed La Haus to evaluate agent quality in realistic customer conversations.   ‍
  • ‍Spanish Hallucination Verifier: The environment included a custom verifier optimized for Spanish-language real estate content, detecting fabricated property details, prices, locations, and investment terms.
