Cornspring Tech Stack

AI-powered data platform for family office investment and accounting workflows

Financial Services London 2–10 employees Founded 2024 Privately Held

Cornspring is a 2-year-old London-based startup building generative AI tools for family offices, with a tech stack centered on Python, FastAPI, and LLMs (Hugging Face, vLLM) deployed on AWS and Azure. The product roadmap reveals a RAG-first architecture—retrieval-augmented generation pipelines and LLM-powered financial data features—paired with Microsoft Office integration (Office.js add-ins), suggesting a strategy to embed intelligence directly into existing family office workflows rather than replace them. Early hiring velocity is accelerating across engineering and data roles, a pattern consistent with a pre-product-market-fit startup scaling technical depth before sales.
