FintechGraphs is a graph-first knowledge hub for payments and open banking — built for the people who ship, regulate, and scale fintech products. We turn the industry's most complex topics — SEPA scheme rules, VOP, PSD2, acquiring flows, settlement layers, open banking APIs — into visual explainers, connected maps, and practical playbooks that teams can actually use. ##### Why We Built It Payments is hard to teach and even harder to look up. Documentation is scattered. Standards are dense. Onboarding a new engineer, PM, or compliance officer takes weeks of tribal knowledge transfer that shouldn't exist. We built FintechGraphs because we've lived that problem — sitting inside banks, PSPs, and scale-ups, watching smart people waste time on things that should already be mapped. So we mapped them. ##### What Makes It Different Most fintech content is linear — articles, PDFs, slide decks. FintechGraphs is a connected graph. Every concept links to the things that depend on it. You don't just read about settlement; you see how it connects to reconciliation, float, dispute flows, and scheme rules — all at once. - **Graph view** — see how topics connect across the entire knowledge base - **Hover previews** — surface context without losing your place - **Stacked pages** — compare concepts side by side - **Backlinks** — always know what references what ##### Who It's For - **Product managers** building payment features who need fast, accurate context - **Engineers** integrating PSPs, schemes, or open banking APIs - **Compliance and risk teams** mapping regulatory requirements to product flows - **Founders and operators** entering payments who need to get up to speed fast ##### Who We Are ![[emrefindik.jpeg|96x96]] **Emre Findik** — Founder Fintech and Payments Product Manager with 12+ years across banks, PSPs, and scale-ups in Turkey and Germany.
