We're nPlan, a Series B startup backed by leading investors, including GV (formerly Google Ventures) and DeepMind's founder, Demis Hassabis. Our technology helps the world's biggest construction projects make faster, more confident, data-driven decisions. By combining one of the world's largest datasets of project plans with advanced machine learning, we forecast project outcomes and reduce risk - reshaping how infrastructure gets built. We work with complex graph data (each with 10,000+ nodes), applying multiple ML and LLM approaches to understanding the data, extracting meaningful insights from it using a proprietary forecasting engine, and empowering deep human interactions - all of which must work efficiently and robustly in production. As a startup, we also keep agile in a fast-moving environment!
