I wanted you to know that I was very impressed by the TheoremOne team. They were well prepared, and the output of the three-day kickoff meeting exceeded my expectations. I look forward to our continued partnership and bringing the Couchbase DBaaS solution to market.

I am impressed with how the various MISO project teams came together and engaged our partner, TheoremOne, to significantly advance our knowledge and capabilities in just six short months - and trust me, they were short!

TheoremOne was a refreshing change from other vendors as they were fully in sync with our needs and vision for the future. They are a high performing group and better than any other vendor I have experienced in my 25 years with American Express. I have recommended them to external companies and recently rehired them at AMEX.

George Rice, Chief Product Owner, American Express
