About Rainbow

Rainbow is a fully digital insurance company focused on small businesses. Founded in early 2022, we have experienced massive growth over the last year—over 3x revenue growth, expanded offerings, and a successful Series A from leading investors in the space.

We develop our own unique insurance products from the ground up, combining innovative solutions with software that automates the process of getting covered and filing claims. In addition, we empower business owners with tools to help them operate with reduced risk. Our insurance service has been live for 2 and a half years, and we are already one of the largest insurers of restaurants in the country, with plans to expand into other insurance niches.

At Rainbow, we are committed to building a world-class product and engineering culture in the Bay Area. While we trust our team to excel independently, we encourage in-person collaboration a few days per week to foster team building and a strong culture.
