Karl Lorey is a Berlin-based founder and builder with 11 years of experience turning data and machine learning into investable products and startups. He founded apistemic and its flagship product startupradar.co to enable AI-driven startup scouting, and previously co-founded a tech-focused €5M VC where he used scrapers and ML to surface early deals. Technically hands-on, Karl ships production scraping and ML pipelines (Python, scikit-learn, Scrapy) and prototyped an ML-driven HTML element detector in his open-source mlscraper project. He has repeatedly moved from research (encrypted DBs at KIT) to product, taking ideas through MVP to funding and handover as interim CTO. Known for pragmatic engineering—“using whatever gets the job done”—he blends data-driven product instincts with operator experience sourcing and monetizing hard-to-get datasets.
