## Questions

### Who runs investment decisions at Styx Urban Investments?

Founders and Chairmen David Zwilling and Florian Fischer share leadership. Zwilling exited a startup in his teens and later ran a family business; Fischer has exposure to Silicon Valley and Tel Aviv startup ecosystems. Principal Erik Walkling supports deal execution and portfolio management. Investment decisions draw on a distributed team that includes a Managing Director for the Nordics, a Venture Partner in Barcelona, and an Expansion Partner focused on German-speaking markets.

### What is an Urban Living Lab and how does it work?

Styx operates Urban Living Labs in Mannheim, Stavanger, Barcelona, and Copenhagen. Each lab gives early-stage startups access to real buildings, infrastructure, tenants, and customers across the real estate value chain. Portfolio companies can test products in live environments before scaling commercially. The model converts physical real estate assets Styx can influence into a sourcing and diligence advantage.

### Does Styx invest only in companies located near its Urban Living Labs?

No. The firm states explicitly that it has invested in and will consider startups across Europe regardless of whether a local Urban Living Lab exists. The labs are an added-value capability, not a geographic restriction. Founders across the continent can access the testing infrastructure remotely or through targeted pilots.

### What investment stages does Styx typically target?

Styx focuses on the earliest stages — pre-seed and business-angel-stage funding — aiming to get startups ready for a seed round. It occasionally follows on into later rounds but positions itself as a first institutional investor. The firm's website frames Styx as "your first investor" and "the Urban Living Lab VC."

### How is Styx's venture activity related to its real estate holdings?

Styx discloses over €25 million deployed into venture capital and more than €100 million in real estate assets under management (per firm website). The real estate holdings — which span residential, light industrial, and municipal assets — serve as testing environments for portfolio companies. The firm also runs an Investment Enablement program that helps traditional real estate players and family offices write their first venture tickets.

### Which sectors does Styx explicitly focus on?

The firm invests in startups across PropTech, Green and CleanTech, Smart City, and ConTech. Confirmed portfolio companies include VREY (solar energy distribution for multi-tenant buildings), Wohnio (heating system optimization in older buildings), and Ectos (construction surplus material management). Styx looks for ventures where the Urban Living Lab model can provide a meaningful testing advantage.
