Its product catalog includes business owner’s policies, cyber, worker’s compensation and a recently launched management liability product for startups with boards or fundraising activity. The company grew its embedded distribution partnerships from 35 at launch to over 100 in the past year, increased headcount five-fold, and reported 30% month-over-month customer growth. CEO Ralph Betesh said revenue grew “exponentially” over the past year as a result of partnership and customer growth, though he did not disclose specific revenue figures. Coverdash has emphasized a path toward profitability even as it scales partner onboarding and product offerings. Coverdash provides an embedded, end-to-end digital insurance experience that lets small businesses get quotes, bind policies, pay, and manage coverage without redirection or speaking to an agent. The product launched in all 50 states and the company works with over a dozen carriers to offer liability, property, workers’ compensation, and cyber policies. Coverdash also offers an API/embedded technology that partners—marketplaces and service providers—can integrate with a single line of code. The startup secured 35 partners pre-launch, signaling early distribution traction. Founded in 2022 and based in New York City, Coverdash was started by Ralph Betesh, David Vainer, and Avery Rubin. The company closed over $2.5 million in seed capital and says future scale and revenue will likely come from policies sold through embedded partners. The new funding will be used for go-to-market initiatives, product and technology development, and hiring.
