Sourced limitations

FIS Prophet
  • Prophet remains a proprietary, license-locked actuarial DSL. Models are written in Prophet's actuarial language and run on FIS's own grid/cloud execution layer; there is no open-source or Python/R native equivalent. FIS's 2024 trade-secrets lawsuit against Montoux — a New Zealand AI startup whose 'Model Replication Module' helped carriers migrate off Prophet — forced Montoux into liquidation in December 2024, illustrating how aggressively FIS defends the installed base against model-extraction and AI-assisted migration tooling.

  • Named-carrier visibility is thin relative to the installed base. FIS claims 10,000+ users at ~850 sites in 65+ countries, but the vast majority of Prophet customers are never publicly disclosed — FIS's corporate award statements tend to name only a small rotating set (AIA, New York Life, Vienna Insurance Group, Generali affiliates, Singlife with Aviva). As with most actuarial modelling software, buyers rely on peer reference calls and SOA/IFoA community knowledge rather than vendor case studies.
    Source: FIS / Prophet Web
  • No Gartner Magic Quadrant or Forrester Wave covers life actuarial modelling as a distinct category. Third-party coverage is concentrated in InsuranceERM and Risk.net awards plus trade-press tech guides. Celent has published insurer cloud-vendor surveys but no dedicated actuarial-modelling Solutionscape for Prophet — buyers lack an analyst ranking and substitute peer networks and consulting firm (Deloitte, Finalyse, Milliman, WTW) recommendations.

Moody's RMS
  • Catastrophe modelling is a near-duopoly between Moody's RMS and Verisk's AIR Worldwide (now Verisk Extreme Event Solutions). The per-carrier deployment surface is rarely published — most production deployments sit inside a reinsurance broker's placement rather than a carrier press release — so the traction axis on this fiche reflects the aggregate platform-count rather than a named customer list.
