• The brief that Attune is a 'Hartford + Two Sigma + AIG joint venture' is incorrect. Public record (Business Wire, 28 September 2016) shows Attune was founded by AIG, Hamilton Insurance Group and affiliates of Two Sigma Investments, each holding one-third. Hartford Financial Services Group has no disclosed equity, capacity or operational role in Attune at any point in the platform's history.

• Total equity funding is not publicly disclosed. Attune was capitalised by the three JV parents (AIG, Hamilton, Two Sigma) rather than by priced venture rounds, and subsequent ownership changes (Coalition acquisition October 2021, sale to Pinnacol Assurance / Cake Insure 4 January 2023) were undisclosed-terms transactions. No venture capital round size has been made public for Attune as a standalone entity.

• BiBERK (Berkshire Hathaway) and Coterie are US small-commercial competitors of Attune, not capacity partners. Attune's disclosed fronting and underwriting paper comes from Blackboard Insurance (AIG) on legacy BOP, Accredited Surety and Casualty (with TransRe-led reinsurance) on BOP+, EMPLOYERS on legacy workers' comp, Hiscox on GL/PL, and — since September 2024 — EverPeak Insurance supported by Pinnacol Assurance on the new workers' comp product. Neither BiBERK nor Coterie appears in Attune's disclosed carrier panel.

• Attune is an MGA / technology-enabled broker platform, not a licensed risk-carrying insurer. All policy paper sits with third-party carriers (Accredited, EMPLOYERS, Hiscox, Blackboard, EverPeak). Unlike Pie Insurance — which moved full-stack in 2023 with its own A- rated paper — Attune has never acquired or become a licensed carrier, so underwriting appetite ultimately depends on capacity partners' continued support.

• No Gartner, Celent, Forrester or Novarica coverage of Attune surfaces in public search. Third-party validation is concentrated in insurance trade press — Insurance Business America, The Insurer, Carrier Management, Insurance Journal, Insurance Insider US, Business Insurance — and Attune's own announcements.

• Convr's total disclosed funding is approximately $18M across two rounds, ending with the $15.2M Series B in November 2019. No later equity rounds have been publicly announced. That capital base is modest compared to well-funded underwriting automation peers, which may constrain the pace of model development and international expansion.

• Convr is a US commercial P&C specialist. Its submission ontology and carrier integrations are built for the US market — standard and specialty commercial lines. It does not serve personal lines, life, health, or workers' comp as primary lines, and no European or Asia-Pacific carrier deployments have been publicly announced.

• Convr's accuracy claim for machine-read data is 91%, which means roughly 1 in 11 data points still requires human review or correction. For high-volume small commercial portfolios this is workable; for complex middle-market risks with long loss-run histories, residual manual touches remain.

• Convr does not replace a policy administration system or rating engine — it sits upstream of those. Carriers that lack mature APIs into their policy admin stack will need integration work to route the structured output Convr produces into downstream underwriting decisions.
