There is a version of due diligence that every legal, compliance, and procurement team in the world knows and dreads. It starts with a request. Someone needs a background check on a counterparty — a supplier, a potential acquisition target, a new hire, a joint venture partner. An analyst opens Google. They open Nexis. They open LinkedIn. They open Companies House. They read, they summarise, they cross-reference. They spend two days on something that should take two hours. And when they are done, the report they produce is already out of date.
Xapien was built to make that version of due diligence extinct. On September 11 2026, the London company announced a $56 million Series B led by Spectrum Equity, with existing investor YFM Equity Partners also participating. The round funds US expansion, continuous monitoring capabilities, and the relocation of CEO Chris Green and senior leadership to Boston — where half of Xapien’s revenue already originates.

What Xapien Does and Why $56 Million Is a Rational Bet
Xapien describes itself as an AI-native research layer for legal, compliance, and procurement teams. The platform searches open-web material, corporate records, sanctions data, and media in multiple languages, resolves similarly named people or organisations using entity resolution technology, and produces a sourced executive-level report in minutes. 350 clients and partners across 15 countries use the platform. Annual recurring revenue grew more than 350 percent in the two years before the round, even though the company sold into the American market without local sales staff.
That last detail justifies Spectrum Equity’s lead. A company that grew ARR by 350 percent over two years while selling into its largest market without a dedicated sales presence has a distribution problem, not a demand problem. The $56 million solves the distribution problem. A Boston office with the CEO and senior leadership on the ground gives Xapien the local commercial infrastructure to match the commercial demand that already exists.
Founded in 2018 by Chris Green, Daniel Secretan, and Shaun O’Mahony, Xapien has built what its investors call the ChatGPT of due diligence — an AI intelligence engine providing contextual background on any company or person worldwide by analysing millions of online sources and generating an executive-level report in minutes rather than days. The governance, risk, and compliance market it addresses is valued at $43.65 billion globally and forecast to reach $111 billion by 2032. Read more UK deep tech and AI stories at BestStartup UK.
Continuous Monitoring and Perpetual KYC. The Next Phase of the Product.
The most commercially significant element of Xapien’s announcement is not the funding amount. It is the product direction. The company is expanding from periodic due diligence checks toward continuous monitoring — what it calls perpetual Know Your Customer, or perpetual KYC.
Traditional KYC is periodic. A bank onboards a client, runs due diligence, and repeats the process every one to three years. The problem is that the world changes between those reviews. A supplier that was clean at onboarding acquires a sanctioned subsidiary six months later. A business partner whose ultimate beneficial owner was straightforward at deal close restructures through a new holding company. Under periodic KYC, those changes are invisible until the next scheduled review.
Perpetual KYC changes the model entirely — monitoring the same entity across the same data sources on an ongoing basis and flagging changes as they occur. For a bank managing thousands of corporate client relationships, this shifts compliance from a periodic cost centre into a continuous risk management capability. UK, EU, and US regulators are all moving toward expectations of continuous monitoring for financial crime risk. Xapien’s product timing is correct.
UK AI Compliance and RegTech. A Category That Is Only Getting Bigger.
Xapien’s Series B lands in a UK AI compliance and RegTech market expanding on every dimension simultaneously. The UK’s Economic Crime and Corporate Transparency Act, the EU’s AI Act, and evolving FATF guidance on digital identity and KYC are all adding to the compliance burden on financial institutions, law firms, and corporates. The manual analyst capacity to meet those requirements has not kept pace.
UK startups raised roughly $17 billion in the first half of 2026, with AI taking approximately $12.6 billion — close to three-quarters of the total and more than four times the same period in 2025. Within that AI total, compliance and RegTech applications represent a growing share.

Frequently Asked Questions
What is Xapien and what does it do?
Xapien is a London-based AI due diligence platform founded in 2018 by Chris Green, Daniel Secretan, and Shaun O’Mahony. It provides legal, compliance, and procurement teams with AI-generated background reports on any company or person worldwide in minutes, searching open-web sources, corporate records, sanctions data, and media in multiple languages using entity resolution and natural language processing.
How much did Xapien raise in September 2026?
Xapien raised $56 million in a Series B funding round on September 11 2026, led by Spectrum Equity with existing investor YFM Equity Partners also participating. The round funds US expansion including a larger Boston office and relocation of senior leadership, as well as perpetual KYC capabilities.
What is perpetual KYC and why does it matter?
Perpetual KYC is continuous Know Your Customer monitoring — ongoing surveillance of counterparties across data sources rather than periodic snapshots every one to three years. It matters because sanctioned entities, restructured ownership, and new risk factors can emerge at any time between periodic reviews. Perpetual KYC flags changes as they occur rather than waiting for the next scheduled review cycle.
