Summary

PropTech founder and operator: Jannes built Zenhomes and the Vermietet.de product from the ground up (founded 2016), scaling it into a market-leading property-management toolkit for private landlords in Germany and taking the business through funding rounds and a strategic transaction with Scout24. vermietet+2
Operator-to-investor transition: After founding and operating high-growth marketplace and proptech businesses, Fischer now runs P3A (his investment/operating vehicle) and acts as a founding angel for multiple startups (upmin, Flagship Founders, Bullfinch, Scaling Spaces), focusing on infrastructure, real-estate tech and climate/energy plays. p3a-holding+2
Exit and partnership mindset: Fischer negotiated and executed a strategic majority transaction with Scout24 (May 2021) while remaining engaged operationally — demonstrating a preference for deals that allow the product to scale within a larger ecosystem while keeping entrepreneurial control to deliver on the original mission. scout24+1
Early marketplace and scaling experience: Before founding Zenhomes/Vermietet.de, Fischer gathered rapid-growth marketplace and venture experience at Rocket Internet and as Managing Director for foodpanda in Hong Kong — background that informed his product and go-to-market approach in PropTech. forbes+1
