We co-founded and led Viafintech (Barzahlen) to 100+ FTE, one of the most successful German fintechs, active in 17 markets across the EU and USA, and sold it in 2021 for a € three-digit million amount to NYSE-listed Paysafe Group. This time we’re building a global champion for prepaid products: gift cards (Apple, Amazon, Google), airtime and eCash all in one simple API. Instead of 5 players in the chain (brand → issuing tech provider → global distributor → local distributor → client), we connect brands directly with clients via the finperks platform. Today 95% of prepaid is still sold in the Global North; we believe that for the gig economy to monetize the Global South, prepaid will be key - from Netflix and Google to Apple and Uber. Kind humans.
