Most payment stacks treat account and wallet payments as passive methods.
We don’t. Nopan is a specialized PSP built by former large-merchant payment leaders, designed to turn account and wallet payments into measurable revenue drivers. Because performance doesn’t come from technology alone. It comes from how payments are designed, tested, and optimized in real-world environments.

NjiaPay is a payment performance partner built for African businesses that rely on digital revenue. As businesses grow, their payment setup often becomes complicated; multiple providers, payments that don’t always go through, no clear view of what’s working, and extra admin for their teams. Small issues quickly turn into lost revenue. NjiaPay brings clarity and structure to that complexity. We connect businesses to multiple Payment Service Providers through one central layer, routing transactions to the best available option and giving a clear view of how payments are performing. The result? Fewer failed payments. More successful checkouts. A better understanding of where revenue is won or lost. We don’t replace providers. We work across them, helping businesses keep more revenue, reduce unnecessary workload and make better decisions about their payments. Payments should be clear, reliable, easy to manage, and accountable for the revenue they impact. That’s payment performance.

iwoca was founded to expand possibilities for small businesses. At iwoca, we believe finance should feel like a superpower, not a headache. That’s why our founders, Chris and James, decided to create a solution custom-built for small businesses. One that strips out the hassle, gets to know what each business needs, and looks for opportunities rather than problems. One that provides access to finance where and when your business needs it. Our partner integrations and our Lending API mean we can provide access to finance where and when small businesses need it. Our award winning credit risk engine help us make faster, more accurate credit decisions built around the performance of the business. We are proud to be NACFB Lender of the year, Xero Financial Services App of the year and, most recently, winner of the £10m Banking Competition Remedies grant. Since 2012, we’ve made funding available to over 50,000 businesses, from cafés to car dealers, salons to solicitors. But we’ve only just started. Our mission is to fund one million small businesses.

Venture capitalists bump into each other at tech conferences, demo days, tech awards and pitch events. This is great, but we believe we all appreciate and enjoy a more structured agenda of gatherings. Why? Because expanding your professional circle is important and hanging out with likeminded people is fun! VEECEE has been established by a few young venture capitalists, for European venture capitalists. We aim to further ignite passion, share experiences, strengthen our network, and make it easier for international VCs to connect to their peers. Our ultimate goal is twofold: To make us become even more active members of the local startup ecosystem and to share learnings with entrepreneurs, founders and investors. As we want to be helpful, insightful and supportive to the start-up ecosystem, we share posts and anecdotes and cover topics such as pitching, KPIs, valuations, business models, and recruitment. The posts are short and punchy and might bring you in the mind of investors. We also organise distinct workshops for our members, mainly thanks to our sponsors!
