Longstack started as a in-house business tool for AMP Agency. I created it to solve numerous problems, while consolidating and expanding on what was previously numerous, expensive 3rd party solutions, many of which failed to meet the unique & specific needs of the agency's creative campaigns. It was the back-end API for numerous campaigns for Toyota, Coke, Levis, The City of Seattle, and more, while also offering valuable Business Intelligence to AMP's numerous client account managers.
