What Thirdfort does

Thirdfort, founded in January 2018 in London by Olly Thornton-Berry and Jack Bidgood, is an AI-powered client due diligence (CDD) platform serving UK regulated firms. The company provides an integrated suite of verification products covering ID verification (NFC chip reading of e-passports with liveness detection and DIATF certification), source of funds analysis (open banking-powered AI extraction and cross-referencing), Know Your Business beneficial owner discovery (Dun & Bradstreet-backed, 96% of reports returned in under one minute), AML screening (sanctions, PEPs, adverse media, CCJ, insolvency with ongoing monitoring), and AI-driven document verification (tampering and forgery detection across 195 jurisdictions). These products were consolidated into a single rebuilt AI-powered CDD platform in October 2025, positioning the company as a unified compliance workflow vendor rather than a point ID verification provider.

The business operates a hybrid revenue model combining a monthly platform subscription fee (covering onboarding, training, support, and intelligent workflows) with pay-per-check or bulk-credit usage pricing (credits valid 24 months), with industry-specific pricing for legal, conveyancing, estate agents, accountants, and law firms. Go-to-market combines direct enterprise sales to large regulated firms with an extensive distribution network of 20+ integrations into case management (Redbrick, ActionStep, Clio, InTouch, ALB, Minerva), CRM (Reapit, Alto, MRI Software), and vertical platforms (GoProposal by Sage, OnTheMarket Software, ProConvey), reaching over 1,500 regulated firms and an additional 500+ firms via partners. A consumer-facing mobile app (3M+ downloads) completes verification for individual clients, and an Inperio insurance partnership ties Thirdfort usage to reduced Professional Indemnity Insurance premiums for over 200 firms.

Thirdfort has raised approximately £25 million across pre-seed, seed, seed-plus, Series A (£15m in March 2022, led by Breega and Element Ventures), and Series A2 (£5m in April 2024), with backing from founders of ComplyAdvantage, Funding Circle, Tessian, Fenergo, and Fidel. The company has offices in London (headquarters), Manchester (client hub opened January 2020), and Sri Lanka (development office opened December 2019), holds FCA authorization and ISO certifications, became B Corp certified in September 2022, and acquired Homeppl (rental check platform) in February 2025 to extend into the letting and rental sector.

Core offering

Thirdfort provides an AI-powered client due diligence (CDD) platform for regulated UK businesses in the legal, property, and accountancy sectors. It combines identity verification, AML (anti-money laundering) screening, Know Your Business (KYB) checks, source of funds verification, and AI-driven document verification into a single automated workflow. Customers — primarily law firms, conveyancers, estate agents, and accountants — subscribe to the platform and pay per check to verify their clients remotely.

The core offering consists of ID Verification (remote identity checks meeting HM Land Registry, Companies House, and DIATF standards), Source of Funds (open banking-powered fund analysis), Know Your Business (beneficial owner discovery), AML Screening (global sanctions/PEP screening with ongoing monitoring), and Document Verification (AI-powered identity document inspection). These products operate within an integrated CDD Platform that centralizes compliance workflows, automates data collection and screening, and provides audit trails. The platform also includes Secure Share for inter-firm report sharing, and is accessible via both a web portal for professionals and a consumer mobile app. Thirdfort serves regulated sectors including legal, property (conveyancing, estate agents), and accountancy, and acquired Homeppl's rental check platform in 2025.
