Premysl Rubes is a founder-operator who built Presto Ventures from scratch as a 100% privately backed fund by successful entrepreneurs and family offices, giving portfolio companies access to operators behind companies like Avast, Škoda, and UiPath rather than just institutional capital. He's known for backing Elin.ai purely at the idea stage—the only one of ~60 portfolio companies he supported this early—and is now shifting from traditional B2B SaaS toward deep tech and dual-use defense technologies, co-launching one of Europe's largest dedicated security/defense-tech funds with a €150M target.
