Austrian PropTech Lystio closes €500k round to refine real estate portal and expand across Europe

The Vienna-based startup Lystio, an AI-native real estate portal, has closed a €500k funding round in order to expand with a focus on further developing their search algorithm and AI-powered features.

In addition to Austrian investors, international business angels from Silicon Valley are participating, including an early Google employee.

“We understood early on that distribution today is driven by content,” says co-founder Constantin Weiland. “Through our content- and creator-first approach, we were able to quickly build our own reach and convert it into direct demand for our platform.”​

In the wider European PropTech landscape covered by EU-Startups in 2025 and early 2026, several AI- and real estate-focused startups have secured notable rounds.

Oslo-based Telescope raised €3.7 million to help real estate owners leverage climate and sustainability risk data; Zurich-based ScyAI secured €2 million to deliver AI-driven risk intelligence for enterprise real estate and insurance teams; Berlin-based vivanta completed a €2.5 million round to expand automated property management; London-based Orbital raised €50 million in a Series B round to scale its AI platform for real estate law; and Swiss PropTech Azuro secured €5 million to develop a new property ownership model.

Together, these rounds represent approximately €63 million in disclosed funding flowing into European real estate and adjacent technology segments.

In this context, Lystio’s investment aligns with continued capital allocation towards AI-enabled infrastructure, risk analysis, legal workflow tools and automation within the European real estate market, albeit at an earlier stage and smaller ticket size.

“Our goal is to build the best platform for users and partners in the long term,” says co-founder Philipp Attensam.

Founded in 2024 by Philipp Attensam, Constantin Weiland, Mikail Celik, and Stefan Wagner; Lystio enables users to list and discover apartments, condominiums, houses, new developments, commercial properties, offices, land, and garages for rent and for buy.

The company’s goal is to build a leading real estate portal for Austria and Europe and create a central digital infrastructure for the real estate market – replacing the traditional “pay-to-rank” model used by existing real estate portals.

Instead of paid placements, a new search algorithm will rank listings solely based on their actual relevance to users. This technology is currently in the testing phase, with rollout being a key milestone in the company’s next phase of growth.

Alongside product development, Lystio has built strong demand, generating over 30 million video views on social media and more than 30k followers. Today, more than 40k people use the platform monthly.

Since its launch, the number of active listings has increased from around 4k to more than 50k. The platform includes rental and owner-occupied apartments, houses, new developments, as well as commercial properties, land, and parking spaces.

“We are consistently investing in product quality, performance, and sustainable growth,” adds co-founder Mikail Celik.

The European real estate portal market is one of the largest digital markets, with billions in annual revenue and strong network effects. At the same time, Lystio believes that structural inefficiencies create opportunities for new, technology-driven platforms.

The company follows a free base model with optional premium features for providers, enabling efficient scaling of supply and demand.

With the completed funding round, Lystio aims to further strengthen its market position in Austria and lay the foundation for expansion into additional European markets.
