I am an Austrian entrepreneur and software engineer with a background in business informatics, artificial intelligence and financial education.
Over the past decade, I have developed software, built digital platforms, published academic research and founded businesses in technology, media, automation and real estate.
Today, my work focuses primarily on real estate, software development and process automation.
Current Work
What I'm building
Active
KeyLiving GmbH
Co-Founder & Managing Director
Technology-driven real estate brokerage with a focus on very high quality — the perfect symbiosis of a top team and highly digitalised support: sales and rentals, management of large-scale projects, branding and marketing, making sure owners, tenants and buyers alike are genuinely well looked after. What we're building and using every day:
The KeySuite — our own in-house system
Digital rental offer — in daily use
The KeyLiving Navigator
The KeyAcademy — our in-house training centre: from theory to hands-on videos and interactive learning scenarios
propvision develops software for the real estate industry of tomorrow. We focus on operating, developing and scaling digital platforms, systems and technological infrastructure — enabling more efficient, data-driven processes across the entire real estate lifecycle, with a particular focus on brokerage and marketing. What we're building:
Our own agentic-first CRM for the real estate industry
Autonomous AI agents
An AI-based real-time sales coach
A proprietary valuation system with its own data aggregator
An automated image-processing pipeline — from raw photo to photographer-grade result, filed directly in the CRM within seconds
Until 2025 I also co-ran CryptoExplorer GmbH, which I co-founded in 2017 — I've since stepped back and support the team as an advisor. Read the story
Research & Open Source
From research project to open-source software
EACL 2024
ScamSpot
Machine Learning · NLP · Open Source
A machine-learning system detecting scam and spam comments on financial Instagram accounts — fine-tuned language model, annotated dataset, browser extension and REST API. Presented and published at the Conference of the European Chapter of the Association for Computational Linguistics (EACL 2024).
Our own AI chatbot, long before ChatGPT became widely used — essentially MCP before the protocol existed. Even in 2025, ChatGPT still couldn't render charts or visualise live data; we did exactly that back in 2023.
Machine learning against scam comments on financial Instagram pages — published at the Conference of the European Chapter of the Association for Computational Linguistics (EACL 2024).
Our introductory book on cryptocurrency investing, co-written with Andreas Mattes and read by thousands — from back when explaining Bitcoin chapter by chapter still felt necessary.
Award-winning image analysis supporting glioblastoma (brain cancer) research at the Medical University of Vienna — a school project that got slightly out of hand: 1,400+ hours in the making.
Premium cryptocurrency research, market reports and indicators — daily analysis and an exclusive community for everyone who wanted to go deeper than the social media feed. All running on our self-built platform — from payment flows to member management and newsletter integrations.
CryptoExplorer Academy
Legacy project
Online cryptocurrency and investing education — no get-rich-quick promises, but a real understanding of safe investing, how crypto actually works, and what makes sense versus what is just hype. All running on our self-built platform — from payment flows to member management and newsletter integrations.
The Erben Report
On hold
My newsletter on investing and personal finance with over 5,000 subscribers — on hold, KeyLiving GmbH and propvision GmbH keep me busy.
