Verisoul

Verisoul operates an all-in-one fake account and fraud detection platform for online businesses. Its front-end web and mobile SDKs collect thousands of passive signals and generate hundreds of active signals in milliseconds, while a backend API optionally ingests identity data such as email addresses, phone numbers, and names. Signals are scored by internally developed machine-learning models, evaluated against customer-specific rules, and returned as risk scores plus an actionable label of "Real", "Suspicious", or "Fake" for each user, account, and transaction.

Product modules include device fingerprinting (returning match probabilities rather than device IDs), account linking and user-network visualization, location/geolocation spoofing detection, email intelligence, phone intelligence (VoIP, SIM farm, and burner detection), bot detection, device risk (anti-detect browsers, virtual machines, emulators), and proxy/VPN detection via active network testing. Add-on identity checks cover ID document verification (advertised at 30 seconds and $0.25 per check) and FaceMatch selfie verification (advertised at 10 seconds, with camera-injection and device-spoofing protection). Platform-level capabilities include a unified investigation and analytics dashboard, a no-code rules engine, identity verification workflows, AI fraud agents that investigate users automatically, and flexible APIs for integration into existing stacks.

The company positions its approach as active, spoof-resistant forensics applied across the full user journey — from first click through conversion and ongoing engagement — rather than passive data aggregation or narrow point solutions.

Founding story

Verisoul was founded in 2022 by Henry LeGard (CEO), Raine Scott (CPO), and Niel Katkar (CTO). LeGard previously served as TransUnion's youngest Director; Scott previously led fraud and risk teams at Ahead Financial and Meta; Katkar worked on identity infrastructure at Capital One. The founders describe starting the company to address declining trust between businesses and online users, a problem they argue AI accelerates.

Business model

Verisoul sells a B2B software platform delivered via front-end SDKs and APIs, with a dashboard for fraud operations teams. Add-on verification products are priced per check (for example, ID Check advertised at $0.25 per check), and the company describes replacing on average about five existing point solutions per customer.

Software-as-a-service subscriptions measured in annual recurring revenue, supplemented by per-check pricing on identity add-ons such as ID Check.

Traction

The company reports scaling from zero to more than 100 customers in the roughly two years since commercialization, with more than 6x year-over-year ARR growth, customers across 12 industries, over 100 million fraudsters blocked, 5M+ fake accounts detected, 100B+ user data points analyzed, and a 4.9/5 customer review score. Customer-reported outcomes cited on its site include $150K in monthly savings at Clay, $190K saved in eight months at Lemlist, 28% fewer false positives at Suzy, and a fintech/rewards customer citing 40% lower fraud rates and 76% lower fraud costs after switching from Sardine.

Latest developments

In December 2025 Verisoul announced an $8.8 million Series A led by High Alpha with participation from Lookout Ventures, Bitkraft, Bain Future Back Ventures, and Third Prime, earmarked for hiring, product development, and go-to-market expansion. The company's site subsequently promotes a "$9M Series A" and reports a partnership with Yonder Data Solutions for fraud prevention in market research, a Verisoul integration in CloudResearch's Sentry product, and recognition of Rakuten Insight for top user quality in 2025.
