​London AI Builder Mixer: From Idea to Scale

​The London AI Builder Mixer is Datamellon’s flagship gathering for founders, investors, and innovation leaders building the next generation of AI-driven companies. This exclusive in-person mixer brings together a curated group of 60 builders for an evening designed to spark real conversations, real connections, and real collaboration.

​Set in the heart of London’s fast-rising tech ecosystem, the Mixer creates an environment where founders, operators, investors, and technical innovators can collide and explore what’s next. No long panels. No presentations. Just meaningful dialogue, real demos, and the kind of ecosystem energy that accelerates ideas into action.

​This edition features a spotlight fireside session titled “From Idea to Scale: Building AI-Native Startups in the Cloud Era”, a deep, practical conversation on what it truly takes to grow AI-first startups in a cloud-powered world. From early validation and product readiness to infrastructure decisions, financing, go-to-market execution, and securing the next raise, the session equips founders with clear, actionable insights for scaling.

​Featured Panelists

​Yommy Ojo

​Systems & Growth Marketing Partner, Online Ascension
Yommy helps founders who have built something great but haven’t yet found a clear, repeatable path to Seed. As a systems and growth marketing partner, he builds the sales and marketing engines that drive real traction — communicating value clearly, designing funnels that convert, and helping founders close early customers with a repeatable go-to-market system.
Founders at this stage don’t need vague marketing. They need sales, validation, and scalable systems — and that’s exactly where Yommy excels.
