German PropTech Arbio Raises €31M To Launch AI-Powered Holiday Rental Platform

The round was led by Eurazeo, with participation from AI-focused VC OpenOcean, existing backers Atlantic Labs, and angels including Philipp Freise and Justin Reizes (KKR), Johannes Reck and Tao Tao (GetYourGuide), and Din Bisevac (Buena).

Constantin Schröder, Arbio Co-founder and CEO, said: “Starting as operators ourselves, we’ve felt where the real pain for operating and managing holiday rentals lies. Therefore, at Arbio we get extremely excited about leveraging AI to change the fundamentals of a traditionally messy, service-heavy sector.

“With our involvement in existing holiday property managers we’re very particular about how we believe building and rolling out our platform delivers the highest value to home owners, so that ultimately travellers have a wonderful time exploring new places.”

Arbio’s Series A takes place amid a broader 2025 wave of European PropTech and travel-hospitality investments focused on automating property operations through AI.

In Germany, fellow Berlin-based player Buena recently secured €49 million to expand its AI-led property management platform and acquisition pipeline, signalling strong investor appetite for technology-first management models. SCALARA added €3 million to digitalise property workflows, while viboo in Zurich raised €3.3 million to scale its AI building-management system into Germany.

Arbio’s AI-native, full-stack approach to short-term rental operations stands out for integrating service automation, acquisitions, and cross-market scaling within a single system. The presence of both Arbio and Buena in Berlin, SCALARA in Brühl, and viboo expanding to Germany, highlights Germany’s growing role as a European centre for innovation in AI-enabled property management and hospitality technology.

Elise Stern, Investment Director at Eurazeo, said: “Arbio is pioneering the AI-native model in one of Europe’s largest and least digitised service sectors. By combining technology, data and operational excellence, they’re redefining what property owners and guests can expect. We believe Arbio will become the category leader in the multi-billion-euro holiday rental management space and we are excited to support them in this ambition.”

Founded in 2022 by childhood friends Constantin Schröder and Paul Bäumler, Arbio began from their own frustrating experiences as Airbnb travelers. Their mission to ensure consistent, high-quality guest experiences has grown into addressing the operational challenges of holiday home owners and management companies across Europe—a market worth $20 billion.

With over 6.5 million alternative accommodation properties in Europe, Arbio notes that management is still largely stuck in the 20th century. Owners face unpredictable returns, constant hassle and poor reviews, while guests experience inconsistent stays. Traditional property managers rely on legacy software, offering patchwork, inefficient solutions.

Arbio is creating an AI-native operating system that functions as a full-stack property manager. Leveraging AI workflows, it automates distribution, accounting, operations, guest communications, and dynamic pricing, delivering higher revenue, lower costs, and peace of mind for owners, while offering personalized, consistent stays for guests.

With the Series A funding, Arbio aims to rapidly expand across Europe, reaching hundreds of thousands of property owners who can benefit from its AI-native management platform. The investment will also accelerate customer acquisition and enhance AI capabilities.
