Fewer still are those that are able to operationalize that intelligence and reap the rewards that being able to see clearer, and further than the competition can bring.

In addition to being a brilliant technologist he possesses a solid command of product and business essentials. In addition to successfully leading the platform and product management of Yell’s largest digital search product, Andrew specifically pioneered Yell’s award winning base of mobility solutions. He is considered a thought-leader within our company and an important part of our transformation to a digitally centric business.
Rich Gallagher,
Andrew combines a rare blend of exceptional technical aptitude / experience (including hands-on), entrepreneurialism and business / marketing savvy rarely present in one individual. Among many digital product efforts that Andrew initiated, his leadership around Yellowbook’s highly successful smartphone applications (Android, iPhone in particular) was extraordinary. I highly recommend Andrew and absolutely look forward to working closely with him again in the future.
