Insight Venture Partners and MissionOG led the £25m funding round.
"We have made tremendous progress over the last 15 months since our last fund raising – and this fund raise is the largest to date. The additional funds will enable us to continue rapidly growing the business internationally by focusing on our products, our people and our customers."
Imperial Innovations and TTV Capital led the £6.2m round to support growth in the UK and US markets.
"This new funding round reflects the great progress Featurespace has made over the last year, including announcing major new customer wins with companies based in the USA. The most recent of these is a new partnership with TSYS, one of the world’s largest payment solutions and services companies, in which Featurespace’s adaptive behavioural analytics platform will be used to reduce fraud for TSYS’ clients."
