Product overview

Quantexa is a London-based company that builds a Decision Intelligence Platform used by banks, insurers, telecoms, and government agencies to detect fraud, assess risk, and understand their customers. The platform connects data from multiple internal and external sources, resolves entities (identifying that different records refer to the same person or company), and builds relationship graphs that reveal hidden patterns between people, organizations, and events. The company was founded in 2016 by Vishal Marria and four co-founders. It has raised around $547 million in total funding, including a Series F that valued the company at $2.6 billion. Investors include Warburg Pincus, HSBC, the Ontario Teachers' Pension Plan, and the Bank of New York Mellon. Quantexa employs over 900 people across offices in London, New York, Amsterdam, Brussels, Singapore, Melbourne, and other cities. Clients include HSBC, Vodafone, Danske Bank, Zurich Insurance, and Novobanco. A Forrester study commissioned by Quantexa found that customers achieved a 228% ROI over three years. In late 2025, the company launched Q Assist, an agentic AI layer built on top of its platform that lets analysts query data in natural language and get contextual answers.
