Sourced limitations

EIS Group
  • Many EIS customer references are hosted on EIS's own site or blog rather than third-party case studies. AIG Canada and AMI Insurance are traceable to Celent Model Insurer write-ups; Desjardins, CSAA, Tokio Marine, Wellfleet and Liberty Mutual Benefits references originate from EIS press releases and case studies. Absolute customer count and revenue are not publicly disclosed.
    Source: EIS Group
WNS Insurance Services
  • WNS is a services and BPM firm, not a software vendor. Carriers do not license a WNS platform — they buy outsourced operations (claims handling, policy admin, underwriting support, finance, analytics) delivered on top of the carrier's existing core system. Proprietary accelerators and analytics assets (e.g., WNS Triange for analytics, Malkom GenAI) exist but are wrapped inside managed-services engagements rather than sold as standalone products.
    Source: WNS
  • Named-carrier disclosure is thin relative to the scale of the book. WNS states it serves 70+ global insurers, reinsurers, brokers and InsurTechs, manages 30M+ claims transactions and $13B+ in claims spend annually, and 10M+ underwriting transactions, but specific carrier identities are largely undisclosed. Public references are concentrated in the Lloyd's/specialty segment (Mosaic, Canopius, Apollo) plus historic Aviva — US P&C and US Life carrier relationships referenced in WNS materials are aggregate and not individually named in public sources reviewed.
    Source: WNS
  • Post-acquisition integration risk. Capgemini completed its $3.3B acquisition of WNS on 17 October 2025; WNS has been consolidated into Capgemini's financial statements since that date and will be positioned inside a new 'Intelligent Operations' business unit alongside Capgemini's existing BPS and digital-ops assets. Carrier buyers evaluating WNS in 2026 should assume account teams, delivery centres, proprietary IP roadmaps (including Malkom / GenAI) and commercial terms are under integration review, with identity, branding and delivery model likely to evolve over the 2026-2027 integration window.
