Boost Insurance

Boost Insurance is a New York-based insurtech founded in 2017 by Alex Maffeo, who previously ran "Project Boost" inside IA Capital before spinning it out as an independent company. Boost positions itself as the "Stripe for insurance" — an API-driven infrastructure layer that lets fintechs, SaaS companies, and other digital platforms embed P&C insurance products into their own front-end experiences without becoming a carrier, MGA, or licensed broker themselves.

Business footprint. Boost has raised approximately $37M across four disclosed rounds: a $3M seed led by IA Capital and Norwest Venture Partners (2017), a Series A, a $20M Series B in May 2021 led by RRE Ventures with Fin VC, Gaingels, Hack VC, Greycroft, Coatue, and Conversion Capital, and a July 2024 strategic investment from BHMS Investments. The company is licensed to develop and sell P&C insurance in all 50 states. Public claims include powering "over $110 billion of coverage" across partners since its first program went live in 2019.

Capacity and partnerships. Boost does not carry risk on its own balance sheet. It operates as an appointed general agent of State National (a Markel subsidiary) and places risk on a reinsurance panel. The original 2018 facility was led by Nephila with Markel Digital and RenaissanceRe. In October 2023, Boost announced a strategic partnership and direct equity investment from Canopius US. By Q1 2024, Boost had added more than $130M in new reinsurance capacity and expanded its panel to over 12 partners. In October 2023, it also launched Boost Re — a US-domiciled protected cell captive — to let MGA and embedded partners participate in their own underwriting economics via a turnkey captive-as-a-service.

What it does. The platform packages four components into a single API: (1) compliance — Boost's 50-state P&C licenses and filings; (2) capacity — fronting paper from Markel/State National plus panel reinsurance; (3) policy operations — issuance, servicing, billing, claims TPA coordination; (4) product configuration — white-labeled commercial and personal lines (Business Owners Policy, Startup D&O, Cyber, Pet Health, Renters, Crypto Wallet Theft, warranty/shipping e-commerce bundles). Distribution partners — fintechs, digital brokers, SaaS platforms, and standalone insurtech MGAs — integrate via API and sell under their own brand. Named partners include Hippo, CoverWallet (Aon), Cowbell Cyber, and Wagmo.

Archetype. Boost is the platform-infrastructure archetype of the embedded-insurance category, distinct from the MGA archetype (Coalition, Counterpart) that owns a specific risk class end to end. Where Coalition automates cyber underwriting for its own book, Boost lets N partners each launch their own programs on shared plumbing. The model follows Plaid (banking-as-a-service) and Stripe (payments) — commoditise the regulated primitives so product-focused teams can ship faster.

What it replaces. For a fintech or SaaS platform that wants to offer insurance, the alternative is either becoming a licensed producer (6–18 months, 50-state filings), partnering with a traditional broker (low margin, manual handoff), or standing up an MGA with its own fronting and reinsurance agreements (12–24 months, capital intensive). Boost compresses this to an API integration. For MGAs, it replaces the patchwork of separate technology, compliance, and capacity procurement contracts with a single vendor.

Market positioning and gaps. Coverage is concentrated in insurance trade press — Carrier Management, Insurance Journal, Reinsurance News, Business Wire — and fintech-specific outlets. No Gartner, Forrester, Celent, or Novarica quadrant placement exists for embedded insurance infrastructure as of April 2026. Boost's 2024 capacity announcement and the BHMS investment signal a shift from pure venture growth toward reinsurance-partner-aligned capital — consistent with the broader hardening of embedded-insurance economics, where capacity is now the scarcer resource rather than technology.

What it does not do. Boost is US-only. It is not a distributor itself (it does not sell direct to end customers), not an underwriting platform for risk selection (its partners own appetite and pricing within configured guardrails), and not a claims system of record (claims are serviced by TPAs within the Boost-managed program). International expansion has not been publicly announced.
