Hear what some of our clients have to say about Rainbow

Rainbow has been an integral addition to our team at a pivotal moment in our trajectory. They have been critical in getting our books cleaned up and instilling more discipline into how we run our business. Andi has served as a valuable strategic partner as we look to scale our business, helping to identify creative financial solutions for our business. Above all, Andi is a joy to work with, a fast thinker, responsive and always up for new challenges.

Sali Christeson

Founder & CEO, Argent

I couldn’t be more pleased with the strategic insights and practical recommendations Rainbow has provided to my business. Their contributions have been transformative. My only regret is that we didn’t engage Rainbow 5 years earlier.

Steve Robins

CEO & Founder, SPARK Healthcare

Andi's superior financial acumen and ability to make things very simple, accessible, and clear make for an incredible combination. She gives every founder a clear view of what they’ve accomplished and a plan to grow their business. But the best part about working with Andi is Andi herself. Her can-do and cheerful personality, coupled with her way of boiling down the most complicated financial aspects, makes her an absolute pleasure to work with.

Katie Dunn

Angel Investor and Advisor/Board Member, Multiple Clients

Andi is always friendly, upbeat, thoughtful, welcoming, and unassuming, yet her presence is strong. She listens intently and contributes very knowledgeably as necessary, all within the capacity of having her CFO hat on and thinking about the bigger business picture. Behind the scenes, I don't know too many people who so prolifically get things done with as much detail as Andi, and on her own accord with both other leaders in the company and our Board of Directors. Although fractional, Rainbow CFO is an invaluable asset to any organization.

Paul Owen

President, Imaware Health

Rainbow CFO is amazing — experienced, savvy, and a dream to work with. They helped us build out the proper financial tools to scale with confidence.
