Behavox lands $175M growth round to scale AI-native compliance platform

Behavox, a London-based AI-native compliance and controls platform serving global banks and other financial institutions, has raised $175 million in preferred equity from funds and accounts managed by HPS Investment Partners, part of BlackRock. The financing is characterized as a growth equity round and is identified in startup databases as a Series D, with HPS acting as the lead investor. Existing institutional backers on Behavox’s cap table include SoftBank, Citigroup, Index Ventures, and Hoxton Ventures, though no other participants were named for this round. As part of the transaction, Behavox fully repaid and retired a $70 million venture-debt facility from Hercules Capital that had been secured in late 2024 to fund its acquisition of Mosaic Smart Data and a strategic investment in b-next. The company describes this raise as its first equity financing since SoftBank invested $100 million in 2020.

The new capital will be used to accelerate Behavox’s global expansion, broaden its Unified Controls Platform, support further mergers and acquisitions, and continue investment in Polaris, its trade surveillance product. Behavox reports that its customer base grew 86% over the past year to more than 100 major financial institutions across five continents, including a significant share of globally important banks. Industry coverage frames the transaction as a major growth equity infusion into the regtech and compliance AI space, where increasing regulatory complexity is driving demand for automated surveillance and risk monitoring. Deal terms and valuation were not disclosed in the announcement or in accompanying coverage, and third‑party funding databases note that valuation data for Behavox rounds, including this one, is not publicly available.

By combining the retirement of venture debt with a sizable preferred equity raise, Behavox is strengthening its balance sheet while positioning itself for additional acquisitions following the Mosaic Smart Data deal. Advisors on the transaction included Ardea Partners as investment adviser and Freshfields Bruckhaus Deringer as legal counsel. The round underscores how large credit and private markets investors such as HPS, now part of BlackRock, are backing AI-driven compliance infrastructure that underpins surveillance, data retention, and policy management for regulated financial institutions worldwide.
