Zowie

Zowie Langdon is a repeat founder and CTO based in The Randstad, Netherlands, with 10+ years across the full arc of company-building: bootstrapped, raised, scaled, exited, and invested. His background is an unusual combination — a Philosophy degree from Leiden University and self-taught software engineering at Amsterdam UAS — that shows up in how he approaches both systems and community. His technical stack runs Python, Django, Docker, and Kubernetes, with deep roots in blockchain and crypto infrastructure.

His most formative exit came through Blockport, a crypto brokerage he founded that was acquired by BUX, where he went on to serve as Head of Technology. BUX was subsequently acquired by ABN AMRO — two acquisition layers, one founder. Since then he's moved fast: a personal knowledge management app called Integrate (Kindle, Chrome, podcasts), and now a stealth AI banking startup with the tagline 'the bank that runs itself,' where he's again Founder and CTO.

In parallel, Zowie runs Catalyst Community — a curated network for founders and operators hosting 10+ events per year, with longer-term ambitions around physical space. He's an active angel investor (Ynteq, Jyper, Reading Rhythms, among others) and a public voice on AI-accelerated development, having appeared on Xebia's podcast to break down vibe coding — the emerging practice of building software with tools like Cursor, Claude, and GPT-4 as first-class collaborators.
