About Lastro

Lastro is a Brazilian proptech company that has built Lais, an autonomous AI agent designed specifically for real estate brokerages. Lais operates as a virtual team member that engages property seekers 24/7 via WhatsApp, dramatically reducing response times from the industry standard of 6 hours to just 15 seconds. The AI qualifies leads, matches properties to client needs, and customizes recommendations in natural conversation. Beyond lead engagement, Lais handles property management operations including payment processing, maintenance request tracking, and listing capture. The platform aggregates interaction data into real-time market intelligence dashboards, revealing trending neighborhoods, popular property types, and highest-performing marketing channels. Lastro has deployed Lais across 1,000+ brokerages in Brazil, impacting over 2 million homebuyers and demonstrating consistent 60% conversion rate improvements. The company raised $15M Series A funding (R$85M) led by Prosus Ventures, positioning it as a leading AI solution for Latin American real estate.
