Accertify Inc.

History and Milestones

Accertify was founded in 2007 by a team of fraud analysts – specifically named as Jeff Liesendahl – who had experienced firsthand the limitations of existing fraud tools as e-commerce exploded and attack vectors multiplied. The company launched its risk management platform and quickly gained traction with merchants seeking to balance security with revenue growth.

In 2009, Accertify expanded into Mexico, and in 2010 it was acquired by American Express, which provided the resources to scale the platform globally. The acquisition allowed Accertify to integrate with Amex’s payment ecosystem while continuing to serve external merchants. Key milestones include the launch of its Chargeback Management Solution in 2011, expansion into EMEA, Australia, and India in 2013, and entry into Japan in 2016.

After 14 years as part of American Express, Accertify was carved out in 2024 via an acquisition by Accel-KKR, a private equity firm specialising in technology investments. This move positioned the company for renewed independence, enabling it to invest more aggressively in product development, partnerships, and go-to-market capabilities.

In January 2026, Accertify announced a significant leadership expansion, appointing Greg Dukat as CEO along with new executives in sales, marketing, and corporate development. The company also released its Cyber Monday 2025 data and entered a referral partnership with RegTech Solutions for the Australian financial services sector in November 2025.

Products and Platform

Accertify’s flagship offering is the Predictive Yes Platform, a unified risk decisioning engine that integrates multiple capabilities:

- Account Protection: Behavioural and device analytics, AI-driven insights, and consortium data to detect and prevent account takeover without relying solely on multi-factor authentication. - Fraud Detection: Real-time scoring and decisioning using machine learning models trained on billions of transactions, identifying suspicious activity at checkout and beyond. - Abuse Protection: Detection of first-party fraud, promotional abuse, and policy violations, helping merchants protect margins. - Payment Optimization: Routing and authentication decisions that maximise approval rates for legitimate transactions while minimising decline costs. - Chargeback Management: Automated representment workflows, documentation generation, and issuer negotiation to recover revenue lost to disputes.

The platform is built on a consortium model: each client contributes anonymised signals, creating a network effect that improves detection accuracy for all participants. Accertify also offers professional services through its Strategic Risk Services team, which provides hands-on fraud analysis and managed services.

Market Position and Verticals

Accertify competes in the fraud prevention and risk management space alongside vendors such as Forter, Sift, Riskified, and Signifyd. Its differentiation lies in the depth of its consortium data (processing over 14 billion events per year), its long tenure serving enterprise clients, and its emphasis on adaptive intelligence that evolves with fraud patterns.

The company serves a wide range of industries, including iGaming/gambling, where its ability to approve good players while blocking bonus abusers and fraudsters is critical. Other key verticals include financial services, travel, retail, and digital marketplaces. Notable clients include globally recognised brands across these sectors (specific names not publicly listed).

Licensing and Compliance

While Accertify itself is not a gambling operator, its platform is used by licensed iGaming operators worldwide. The company maintains compliance with data privacy regulations including GDPR and CCPA, and its fraud prevention solutions help clients meet regulatory requirements for anti-money laundering (AML) and responsible gambling through advanced KYC and transaction monitoring capabilities.

Headcount

Accertify does not publicly disclose its exact headcount. Based on its global footprint (offices/employees across North America, Europe, Asia, and Australia) and the volume of transactions processed, the company is estimated to have between 300 and 500 employees, though this is an approximation. The official company LinkedIn page describes it as “a leading provider” with “more than 10 billion transactions” processed.
