About Rainbow

Rainbow is a fully digital insurance company focused on small businesses. We started in early 2022 but have experienced massive growth over the last year. We've over 3x in revenue, expanded our offerings, and have raised our Series A from leading investors in the space.

We develop our own unique insurance products from the ground up, combining them with software that automates the process of getting covered and filing claims. We also provide business owners with tools to help them operate with less risk.

Our founding team has a proven track record in Insurtech and product development, having previously built a startup that scaled to 50 employees, served the largest insurance companies in the world, and raised over $40M in venture capital.

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