INFOGRAPHIC: LATAM's Top Weekly Startup Funding—Week 40, 2025

Latin American startups raised over $43 million this week across AI-powered real estate automation, SME credit infrastructure, rental fintech, and healthcare virtual assistants. From simplifying property transactions to expanding credit access and digitising patient interactions, founders are betting on data-driven platforms to modernise traditional industries across Brazil.

Brazilian proptech Lastro secured a $16 million Series A round led by Prosus Ventures, with participation from FJ Labs, Endeavor Scale-Up Ventures, Canary, QED, and 1Sharpe Ventures. Founded in 2021, the company developed Lais, an AI assistant built for real estate agencies and property managers to qualify leads, streamline communication, and accelerate deal conversions across rentals and sales.

By automating customer engagement and reducing manual back-and-forth between brokers and tenants, Lastro aims to position itself as the operating layer for Brazil’s real estate sector. The capital will be used to scale Lais and deepen its footprint in Latin America’s fast-growing AI market.

Close behind, Brazilian fintech Zippi raised a $15.9 million Credit Rights Investment Fund (FIDC) led by Itaú and Verde Asset to expand its lending capacity. Built to serve entrepreneurs and informal workers who banks traditionally underserve, Zippi offers digital credit solutions for small businesses with an emphasis on underwriting speed and accessibility.

The company currently serves more than 100,000 active clients and managed $15 million in assets last year. With the new facility, Zippi plans to double its credit portfolio by the end of 2025 while investing in artificial intelligence to enhance risk models and deliver personalised lending at scale.

Brazilian rental-fintech CredAluga closed an $11 million Series A led by Provence Partners, with participation from Caravela, Honey Island by 4UM, and Norte. The company partners with real estate agencies to offer rental guarantees and financing products such as Fiança CredAluga and Fundo CredAluga, removing traditional bottlenecks in Brazil’s rental approval process.

With more than 1,300 agency partners and 30,000 active rental contracts, CredAluga experienced a 200% growth rate last year. The company will deploy the funding to expand nationally, roll out new financial products, and embed AI to optimise underwriting and fraud prevention.

And finally, Brazilian healthtech WorkAI secured a $1 million investment from M2 Digital to expand its AI-powered virtual assistant for clinics, hospitals, and service providers. Built to operate through WhatsApp, the platform automates appointment scheduling, triage, reminders, follow-ups, and system integration, reducing missed consultations and manual administrative work.

Founded in 2024 and reporting monthly revenue growth of 30%–40%, WorkAI says its platform has cut operational losses from no-shows and miscommunication by up to 47% in healthcare environments. The company now plans to push further into education and financial services while scaling across Latin America.
