What Bunker does
Bunker Protect, Inc. (DBA Bunker and Build Bunker Insurance Services) is a private commercial insurance agency founded in 2015 and headquartered in Madison, Wisconsin, that distributes small business and specialty commercial insurance through a digital-first platform. The company serves 22,000+ clients across verticals including contractors and construction, IT and technology, healthcare, dental and medical practices, restaurants and food service, trucking, retail, professional services, and gig economy platforms, offering a broad product portfolio that spans General Liability, Professional Liability/E&O, Business Owners Policy, Workers Compensation, Commercial Auto, Commercial Umbrella, Cyber Liability, D&O, EPLI, Builders Risk, Equipment Floater/Inland Marine, Cargo, Liquor Liability, Commercial Trucking, Business Interruption, Product Liability, Errors and Omissions, Bonds, Disability, and Mechanical Breakdown coverage.
The platform combines a self-serve online quote portal (5-10 minute bindable quotes with save-and-continue functionality) and a Client Center portal for policy administration, certificate of insurance management, subcontractor COI tracking, and claims, complemented by agent-assisted support via phone, email, chat, and text. Its most differentiated product is Usage Based Insurance (UBI), co-developed exclusively with Chubb, which enables gig economy platforms to provide hourly-priced short-term coverage (3-16 month terms) to independent contractors at $0.30/hour, with claims of reducing corporate Workers Compensation costs by up to 75% and accelerating onboarding by up to 25%.
Bunker earns revenue through carrier commissions on traditional policies (annual billing, quote-based pricing) and usage-based premiums on UBI (monthly billing in arrears), with entry pricing starting at $21/month on installment plans. Distribution runs through a multi-carrier network (Chubb, Hiscox, The Hartford, Markel, CFC, Coalition, Great American, Progressive, Philadelphia Insurance Companies, Coterie) and gig-economy channel partnerships via terms-of-service integration. The company reports a 98% client retention rate, 4.4/5 Trustpilot score across 809 reviews, 94% customer satisfaction, and has raised approximately $8M in disclosed venture funding across 2016-2018 rounds led by Comcast Ventures, Route 66 Ventures, and Omidyar Network.
