AI compliance platform Behavox raises £130.3m from HPS Investment Partners and SoftBank
This article covers Behavox, an AI startup headquartered in London, securing a £130.3m preferred equity investment from funds and accounts managed by HPS Investment Partners to close a growth funding round. The financing is intended to accelerate the startup's global expansion, broaden its Unified Controls Platform and fund targeted M&A, supporting large regulated financial institutions in their compliance and surveillance efforts.
Behavox has secured a £130.3m preferred equity investment from funds and accounts managed by HPS Investment Partners, closing a growth funding round that the company says will be used to accelerate global expansion, broaden its Unified Controls Platform and pursue targeted M&A. The deal comes as Behavox — an AI startup headquartered in London — reports rapid commercial momentum and a customer base that has grown 86% to more than 100 major financial institutions across five continents.
Why it matters
Large, regulated financial firms are under rising pressure to detect misconduct across vast volumes of communications and trading data. Behavox’s financing signals continued investor appetite for AI-driven compliance and surveillance tools that promise to unify communications and trade monitoring workflows. For banks, asset managers and regulators, platforms that reduce fragmentation across data sources and surveillance processes can materially cut investigation times and compliance risk.
Inside the product
Behavox markets a single, integrated controls framework that combines communications surveillance (Quantum), trade surveillance (Polaris), regulatory data retention (Intelligent Archive) and policy management (Pathfinder). Polaris, introduced in 2025, is described as a next-generation trade surveillance product that covers market abuse detection across all 10 major asset classes on one AI-native platform. The company says Polaris can operate standalone or alongside Quantum, using agentic AI to assemble related chats, emails, voice and archived records into a single case file.
Behavox reports pipeline growth of more than 80% since the start of the year and highlights that the unified workflow between communications and trade surveillance is driving demand among large market participants.
Who are the investors?
The principal investor in the transaction is investment funds and accounts managed by HPS Investment Partners, identified in the announcement as part of BlackRock. HPS joins an existing institutional cap table that includes SoftBank, Citigroup, Index Ventures and Hoxton Ventures.
Behavox also used the financing to fully repay and retire a £52.1m credit facility previously provided by Hercules Capital. That facility, arranged in autumn 2024, supported the company’s acquisition of Mosaic Smart Data and a strategic investment in b-next, moves Behavox says accelerated its entry into trade surveillance by adding FICC front-office analytics and capital markets trade surveillance expertise.
Ardea Partners acted as Behavox’s investment advisor. Legal counsel to Behavox on the transaction was Freshfields LLP, led by London partner Rhys Evans with associates Jo Lee, Jennifer Okoye, Megan Rodgers and Jonathan Stelzer and support from Ethan Klingsberg, Co-Head of US Corporate and M&A.
In the announcement, Ruslan Sergeyev, Managing Director at Hercules Capital, said:
Our partnership with Behavox has been highly successful. We congratulate Behavox and HPS on this transaction and look forward to future opportunities to partner.

Founder perspective
In the announcement, Erkin Adylov, Founder and CEO of Behavox, said:
Behavox set out to give the world’s most demanding institutions a single, AI-native platform to manage risk and meet regulatory obligations. HPS brings the scale, sophistication, and long-term perspective to help us reach more institutions in more markets. Their investment recognizes the strong platform we have built and positions us to pursue strategic acquisitions that expand our capabilities and accelerate global growth.
Adylov and the company point to profitability since 2023 as a foundation for reinvestment in R&D, product expansion and international growth. This is Behavox’s first equity financing since a 2020 investment from SoftBank.
The bigger picture
The transaction illustrates several trends in European and global fintech adoption. First, institutional capital continues to back later-stage AI companies that serve regulated industries where compliance and surveillance are mission critical. Second, profitable growth models that combine recurring enterprise contracts with targeted acquisitions remain attractive to credit and private market investors. Behavox’s deal — alongside the repayment of a Hercules facility that underpinned prior M&A — underlines how debt and equity tools are being used in tandem to fund expansion.
The company’s existing relationships — including commercial ties with SoftBank and a client base spanning more than 100 major financial institutions — highlight that buyers of compliance technology are increasingly prepared to adopt integrated, AI-led platforms rather than piecemeal point solutions.
This financing will almost certainly be watched by other UK and European firms building AI tools for regulated markets, where regulatory scrutiny and the cost of non-compliance continue to drive spending on surveillance, data retention and analytics.
Behavox’s London headquarters and global presence — with offices across North America, EMEA and APAC — mean the deal also feeds into wider UK ambitions to remain a hub for enterprise AI companies serving financial services and regulated industries across Europe and beyond.
