In 2012, Grant Cooper and Matt Pattoli founded Social Vantage, a digital advertising agency. Over the course of 7 years, Social Vantage served over 1,000 clients in 22 different countries. In 2019, Social Vantage was successfully acquired by a larger advertising agency.

In early 2020, Grant and Matt created their own advanced tracking system using excel sheets. These sheets ultimately became the initial prototype of Cometly.

After a few months of early development, Grant and Matt began using the first version of Cometly, which provided them complete transparency in their ad performance.

In April 2021, Cometly launched the first version to the public for all advertisers to better track, optimize, and scale their ad campaigns.
