Stellaris Venture Partners led the round, with Y Combinator and Arali Ventures also participating.
Acacia Insurance operates from Waltham, Massachusetts, US, and has provided services to clients throughout New England for more than 30 years.
Apax Partners is reportedly aiming for a valuation close to €600m ($691.56m) for GamaLife, a European life insurance consolidator.
The move will give insurance agencies new options to automate customer service, quoting and call routing.
