What Thomas International does

Thomas International Ltd is a UK-based psychometric assessment company founded in 1981 and headquartered in Marlow, operating across 140+ countries with 251–500 employees and a customer base of 10,000+ organizations ranging from SMBs to global enterprises such as Siemens, BP, Porsche, Red Bull, Carlsberg, and IFS. The company builds validated behavioral (PPA/DISC), cognitive (GIA), personality (HPTI/Big Five), emotional intelligence (TEIQue, launched May 2025), and 360-degree feedback assessments, all reregistered with the British Psychological Society, and delivers them through the Thomas CXI (Connection Intelligence) platform that integrates Thomas Connect for team engagement and Thomas Assess for psychometric testing, with the ThomAI coach providing AI-driven manager guidance.

The platform's commercial motion is a hybrid of direct enterprise sales, a three-tier partner channel (referral, reseller, and embedded/API), and self-serve SMB access via Thomas Connect and Thomas Assess. Revenue is generated primarily through annual subscription tiers (Team, Professional, Enterprise) of the Thomas CXI plans, supplemented by partner-channel revenue (referral fees, reseller margins, usage-based embedded pricing), training and accreditation programs, and professional services. The company holds ISO 27001 (December 2025), ISO 9001 (2022), SOC 2, and GDPR attestations, and won the 2025 Engage Award for Best Implementation of AI in Employee Engagement for the ThomAI coach. Distribution is further extended via localized regional websites across EMEA, APAC, and LATAM, with 375,000+ assessments delivered through the partner network.
