About lemon.markets Our mission is providing better opportunities to invest in capital markets. By empowering FinTechs and Banks to offer investment products, we help create financial well-being for their customers. In pursuit of this goal, we strive to open 100 million securities accounts within Europe in this decade. lemon.markets builds infrastructure for financial services and technology companies powering the next generation of investment products. From enabling a Fintech to launch their first investment product, over allowing e.g. a Neobank to embed investing into their product to bringing investing into a completely new context. Our API-first infrastructure makes launching an investment product customer-centric and compliant. We abstract all complexity for our partners through a well documented API, a self-service customer operations portal and operating in a clear regulatory framework. Enabling partners to launch in weeks, not months. We have experienced first hand that brokerage infrastructure is broken. Building an investment product used to be highly expensive, challenging and cumbersome. We ease this pain by shielding our partners & their customers from the underlying complexity - and with that, we make investing more accessible to everyone. Because that’s exactly what we enjoy, going to places nobody else dares and solving hard problems. This not only creates tons of value when done right, but attracts the smartest minds - because outlier companies are built by exceptional (& diverse) people like you.
