Jonne de Leeuw has worked across nearly every stage of the capital stack, from M&A at ING to growth investing at Cyrte and HPE Growth to venture debt at Kreos, before founding his own fintech company and later joining Endeit to lead its fintech team, where he's known for payments and infrastructure deals like PPRO, Solarisbank, and NomuPay, plus travel tech investments like Tiqets. He works hands-on with the companies he backs through board roles, spends over 100 days a year traveling to meet founders across the Netherlands, Germany, and Sweden, and brings a practical, mass-market view to trends, watching how everyday consumer habits, like using WhatsApp or Dropbox, end up shaping business tools later on.
