Sourced limitations

  • Insurity is not plug-and-play; implementations typically require a third-party systems integrator, and budget planning must include data migration and ongoing support alongside the core license — these usually make up a significant share of first-year spend.
    Source: Nerdisa
  • Insurity's presence in Celent's 2023 North America P&C policy administration report placed it among 19 profiled vendors; the three XCelent awards (Advanced Technology, Breadth of Functionality, Customer Base and Support) went to Guidewire PolicyCenter that cycle.
  • One Inc is a US-only insurance payments network; there is no documented European or UK carrier footprint, and pricing/terms are not publicly disclosed — carriers procure via direct sales rather than self-serve onboarding that generalist processors (Stripe, Adyen) offer.
    Source: One Inc
  • The platform depends heavily on banking and wallet partners (J.P. Morgan Payments, U.S. Bank, PayPal/Venmo, Apple Pay, Google Pay) for rails; carriers adopting One Inc inherit this dependency stack rather than running direct processor relationships.
