A New York-based startup that uses artificial intelligence to help banks and asset managers screen for rogue activity among their employees just raised $70 million.

Software company Behavox, which is able to analyze massive amounts of data like employee emails, texts and calls through a technology known as natural language processing, raised 40% more money than it had initially targeted, according to a source familiar with the deal.

It’s the latest example of investor interest in fintechs focused on helping firms solve compliance issues, known as « regtech. »

As of the third quarter of 2018, investors had poured twice as much funding into regtech companies than in the entire prior year, according to research provider FinTech Global .

And regulations for financial institutions are only getting more complex. A recent survey conducted by Intertrust of 500 financial services executives found 85% expect regtech demand to grow until at least 2020.

Behavox’s investors were not disclosed. Citigroup previously led a $20 million round for Behavox in November 2017, which venture capital firm Index Ventures also participated. In November 2017, Behavox was valued at $200 million, though a more recent valuation could not be learned.

A spokesperson for Behavox declined to comment on the funding round.
