London-based insurtech startup Hyperexponential has raised $73m in a Series B equity funding round led by Battery Ventures, with participation from existing investor Highland Europe and Andreessen Horowitz. Founded in 2017, Hyperexponential uses predictive data and insights to help insurers and reinsurers make better informed pricing decisions. The company plans to expand beyond its current operations in the UK and Poland to the US market, with plans to open a New York office and double its headcount to more than 200. Hyperexponential also aims to expand into adjacent markets, including SME insurance.
