Tackling housing inequality with LaHaus

July 2024

La Haus partnered with Collinear to tackle LATAM’s extreme housing inequality with $1B in gross housing sales

‍
In 2020, Jerónimo and Tomás Uribe wanted to transform real estate transactions in LATAM through a digital-first approach. They built La Haus, a platform that curates housing supply, matches it with demand and facilitates the transaction. With a funding round backed by Jeff Bezos, La Haus now makes the home-buying experience as seamless as “looking for their next flight at delta.com.”

Building on its digital-first approach, La Haus was looking to augment its sales cycle with Generative AI. In particular, they were building a digital sales agent that co-pilots the home buying process with a human sales associate. However, the solution hit a roadblock as their current models ran into hallucination issues. To complicate matters, addressing hallucination brought on latency challenges, creating a poor customer experience.
