Leo Anthias is a serial founder and CEO with 11 years of experience building developer-focused and data science platforms from London to Silicon Valley. He founded and led product and engineering teams at Datapane and NStack—shipping popular open-source reporting tools and serverless model deployment used by customers like Peloton and TripAdvisor—and now runs Pump Up to solve scaling 1:1 sales interactions. Comfortable spanning hands-on engineering (Scala/C/C#/React) to CEO responsibilities, he has repeatedly turned research-grade tooling into user-facing products and learned hard lessons about monetizing open source. His background combines humanities training from St Andrews with YC and EF startup training, giving him a rare mix of storytelling, product sense, and technical rigour.
