What Greater Insurance Service does
Greater Insurance Service Corp. is a private, independent insurance agency and marketing corporation founded in 1974 and headquartered in Cottage Grove, Wisconsin. The company distributes a broad portfolio of personal and commercial insurance products through 18 branch offices (17 in Wisconsin, 1 in Minnesota), online quote forms on greaterinsurance.com, and phone-based agent sales, representing over 75 insurance carriers across personal lines (auto, homeowners, life, term life, health, dental, vision, disability, long-term care, flood, motorcycle, recreational vehicle, watercraft, renters, annuities) and commercial lines (business owners policy, commercial auto, general liability, workers compensation, bonds, trucking, construction, farm).
The company operates on a fully third-party technology stack with no proprietary platforms: its website and quote forms run on Insurance Website Builder (ITC), and its customer self-service portal is built on Vertafore/CSR24. The technology footprint is conventional agency infrastructure; no AI/ML, APIs, or proprietary algorithms were identified. Growth has historically been driven by acquiring local Wisconsin and Minnesota agencies and retaining their brands as wholly-owned divisions under the GIS Corp. umbrella.
Greater Insurance Service earns revenue through commissions paid by the insurance carriers it represents, with pricing set on a quote-by-quote basis by carriers rather than by the agency. Its go-to-market is a hybrid model: licensed agents in physical branches selling to local individual consumers, families, and SMB/commercial accounts (including trucking, construction, and agriculture), supplemented by online self-service quote capture and customer referrals. The customer base is horizontally segmented with no disclosed enterprise or single-customer concentration. The company is management-led (CEO Sherri Gjermo, EVP Mike Ausing) with no disclosed external private equity, venture, or institutional investors.
