Sebastian Salomon is the CGO and co-founder of oneBanking, a Malta-registered fintech building an all-in-one app that fuses everyday banking, crypto, and an AI assistant designed to save users money. A 31-year-old German serial entrepreneur, Sebastian started his first company, an e-commerce sports-nutrition business, straight out of his studies in 2016, then co-founded a business-coaching venture that he says has worked with thousands of founders and small companies, giving him a broad read on where technology and money are heading next.

Why you should listen

Sebastian's starting point is a gap that European crypto users will recognize. In the wake of the EU's MiCA regime, a number of global platforms pulled back or reshaped their European offerings, leaving Europeans with fewer clean, regulated ways to buy, hold, and cash out of crypto. oneBanking pitches itself as a fully regulated bridge across that divide: a single app where fiat and digital assets sit side by side, where conversions are meant to be near-instant and cheap, and where users can move coins out to self-custody, including via a hardware-wallet integration with Switzerland's Tangem. Layered on top is the project's own oneToken, positioned as the engine of the ecosystem and partly funded by its community. The framing throughout the conversation is that the old, app-by-app model of personal finance is about to be collapsed into one place.

The more distinctive idea is what Sebastian means by AI banking. Rather than bolting a chatbot onto a banking app, oneBanking is building what he describes as an AI assistant with the trappings of an actual employee: its own phone number, email, and messaging accounts, hooked into your finances and into thousands of comparison platforms such as Germany's Check24. The promise is that the assistant doesn't just flag that you're overpaying; it acts, switching providers in your name, hunting discounts on insurance, energy, and mobile plans, and even timing a flight booking to a cheaper day. He argues the real payoff is on the business side, where an AI combing through a company's stack can surface duplicate software seats and overpriced contracts, then negotiate them down. He frames small monthly savings as genuinely life-changing for ordinary households, which is the emotional core of the pitch.

On timing, Sebastian says the app launches at the end of June, rolling out in stages: IBAN accounts and cards first, then crypto and the AI assistant a few weeks later, with EU passporting and a oneToken offering slated for later in the summer, and a longer-term ambition to extend into sports and real-estate tokenization and well beyond Europe. The conversation closes with the hot take round, where he plants his flag as a Bitcoin guy who has broadened into a wider portfolio through his Web3 work, predicts the legacy banking system will essentially disappear within a decade as AI banking matures and regulation catches up, points to his daily phone calls with oneBanking's own AI as a glimpse of a future that's already here, and lands on Star Wars as his sci-fi pick.
