Liberty Mutual Insurance — Company Profile
What it is: a policyholder-owned insurer selling personal lines through independent agents and direct. It was founded on July 1, 1912, in Boston, Massachusetts, as the Massachusetts Employees Insurance Association (MEIA) — formed by a group of 15 Massachusetts executives after the state’s 1911 law required employers to carry workers’ compensation insurance — and renamed Liberty Mutual Insurance Company in 1917. It has operated as a mutual holding company (Liberty Mutual Holding Company Inc.) since 2002. There is no individual founder: it was a group founding, and any source naming one person as “the founder” is oversimplifying.
Verdict: Legit Our rating: Not yet rated — the evidence check is published (see the legit check); numeric scoring with visible inputs is in progress, and we do not publish a number without them.
Liberty Mutual is a real, licensed, century-old mutual — legitimate by every identity and financial-strength check we run. The caution is service evidence: its regulator complaint index is the highest of the six carriers profiled here, well above the market benchmark, even though its score in J.D. Power’s 2025 claims study was strong. Fit also depends on channel: most personal-lines policies are sold through independent agents under the Liberty Mutual and Safeco brands. Full verdict evidence: Is Liberty Mutual legit?
The evidence
- Identity & scale: founded July 1, 1912, in Boston, Massachusetts, as the Massachusetts Employees Insurance Association (a group founding by 15 executives — no individual founder); renamed Liberty Mutual in 1917; mutual holding company structure since 2002; headquarters at 175 Berkeley Street, Boston. Personal lines are sold through 10,000+ independent agencies (Liberty Mutual and Safeco brands), plus call centers and online.
- Market position: seventh-largest U.S. private-passenger auto insurer — $11.7B in direct premiums written and 3.3% market share in NAIC’s 2024 data (via the Insurance Information Institute). Rankings that exclude members-only USAA list Liberty Mutual sixth.
- Complaint pattern: NAIC complaint index for auto insurance of 2.86 — well above the 1.00 benchmark and the highest of the six carriers profiled on this site (compiled by CarInsurance.com, August 2026). Other compilations produce lower figures on different bases; every compilation we checked still puts Liberty Mutual above the benchmark.
- Financial strength: AM Best affirmed an A (Excellent) Financial Strength Rating for Liberty Mutual Holding Company members in September 2025 — a strong grade, one notch family below the A+ and A++ grades held by the other five carriers profiled here. Ratings can change — check AM Best for the current rating before relying on it.
- Pricing: prices are individualised and vary by channel: an independent-agent quote (including through Safeco), a call-center quote, and a direct online quote for the same driver can differ. That makes Liberty Mutual one of the carriers most worth quoting through more than one route.

Review Liberty Mutual
Liberty Mutual questions
Who founded Liberty Mutual?
No single person. It was founded on July 1, 1912, as the Massachusetts Employees Insurance Association, by a group of 15 Massachusetts executives, after the state’s 1911 workers’ compensation law required employers to carry coverage. It took the Liberty Mutual name in 1917 and converted to a mutual holding company structure in 2002.
How do I buy Liberty Mutual insurance?
Three ways: through a local independent agent (under the Liberty Mutual brand, or Safeco — which sells only through agents), by phone, or direct online. An independent agent can quote competing carriers alongside it, which suits a company whose prices vary by channel.
Why does this profile say “Not yet rated”?
We publish a numeric score only with the inputs behind it visible on the page. This company’s evidence check (on our Is It Legit page) is complete; its full numeric scoring is in progress, so the honest label is “Not yet rated” rather than an invented number.
