Lastro Secures USD$15M Series A led by Prosus Ventures, to Empower Brokers Across Brazil

Lastro, a Brazilian AI-powered proptech transforming how properties are bought, sold, and managed, has raised $15 million in a Series A round led by Prosus Ventures. The round also saw participation from FJ Labs, Endeavor Scale-Up Ventures, Canary, QED, and 1Sharpe Ventures. With the new funding, Lastro aims to accelerate product development, enhance the broker and customer experience, and expand integrations across Brazil’s leading property listing portals.

Transforming Real Estate Through AI

Brazil’s trillion-dollar real estate market remains highly fragmented and reliant on manual processes. Lastro’s AI assistant, Lais, is changing that reality—automating repetitive tasks, qualifying leads, and improving communication, primarily through WhatsApp, the country’s main commerce channel.

To date, Lais has engaged with over two million property seekers and serves more than 1,000 brokerages across Brazil. The company’s technology has already reduced broker response times from hours to just seconds, improving conversion rates and operational efficiency.

“Brazil’s real estate sector is massive and filled with simple, repetitive, and time-consuming tasks—the kind of work where artificial intelligence excels,” said Allan Paladino, CEO and co-founder of Lastro. “Unlike many technology solutions that aim to replace brokerages, our goal is the opposite: to empower them so they can focus on what they do best—building relationships with clients.”

Why Prosus Invested in Lastro

For Prosus Ventures, this investment highlights a growing focus on AI-driven solutions that deliver real-world impact in everyday industries.

“In Brazil, where WhatsApp has become the backbone of commerce, Lastro’s AI platform is uniquely positioned to transform how properties are bought and sold,” said Rafael Barbalat, Investor at Prosus Ventures LatAm.

Barbalat added that Lastro’s domain-specific technology, trained on millions of real estate conversations, gives the company a distinct competitive advantage and the potential to scale globally.

“We see tremendous potential for Lastro to redefine property transactions worldwide,” he said. “With Prosus’ global reach and experience scaling technology companies, we’re confident we can help catalyze this journey.”

Empowering, Not Replacing, Brokers

While many proptech platforms bypass traditional intermediaries, Lastro’s model strengthens them. Its AI assistant, Lais, automates lead qualification, manages property portfolios, and supports customer engagement, enabling brokers to prioritize client relationships and sales strategy.

By turning real estate conversations into actionable insights, Lastro also delivers market intelligence on trending neighborhoods, property types, and marketing effectiveness through intuitive dashboards.

A Strategic Bet on WhatsApp Commerce

With over 200 million Brazilians using WhatsApp for daily transactions, the app has become the de facto operating system for commerce in the country. Prosus Ventures, through its investments in companies like Zapia and Luzia, recognizes the power of this channel to connect businesses and consumers.

Lastro leverages WhatsApp’s ubiquity to meet users where they already interact, streamlining communication, negotiation, and transaction management within a single, familiar interface.

Founded in 2021, Lastro pivoted to artificial intelligence in 2023 and launched its virtual assistant Lais in 2024. Built on proprietary AI technology, the platform automates real estate workflows via WhatsApp, helping nearly 1,000 brokerages cut costs and boost lead conversions by up to 60%.

To date, Lastro has raised over $20 million from leading investors, including Prosus Ventures, Canary, QED, 1Sharpe, FJ Labs, and Endeavor Scale-Up Ventures.

Building the Future of Real Estate

This new investment marks Prosus Ventures’ continued commitment to supporting transformative Latin American startups, following earlier investments in iFood and OLX. With Lastro, Prosus is backing a new generation of AI-first companies redefining how essential industries operate.
