"We not only have >20% more accurate data, we also have seen a significant increase in performance..."

"We trialed Cometly against TripleWhale for a considerable amount of ad spend, we quickly saw Cometly's superiority. Over 20% more accurate data, and improved performance on all our ads due to data being fed back to Facebook. Not only has our performance and accuracy improved, but our peace of mind has quadrupled. Knowing that our team can trust the results they see is essential to running and scaling a business."

Mark Hodierne

"I came to Cometly after a few months using one of the existing market leading tracking systems. That system was incredibly complex and actually increased my workload. Cometly was a complete surprise. The setup is impossibly simple and the user interface is a dream compared to the competition. Instantly, my life has been made easier. And the best news is that the software continues to be improved in ways that add more and more value to me. That's because super experienced marketers have developed Cometly. The tracking solution they've developed fits my business like a glove."

Luke Chittick

"I want to start this by saying “you have no idea….” but I know you actually do. However, I’m going to start it like that anyway… you have NO IDEA how much time Cometly saves me! Let’s break it down for fun … conservatively it saves me at least an hour a day. So that would be 365 hours a year which equates to about 2 weeks out of the year that I had been dedicating to crunching numbers! And… I hated crunching numbers! I’ve never been a math guy and looking at numbers gives me a headache. With Cometly, the decision on when to cut or scale ads is now so easy! Very grateful for this and I hope no one else, outside of the founding members, purchases this because I feel like we have such an advantage!… it’s almost like we are cheating."

Andreas Häggkvist
Business Owner

"Have to say a huge thank you to Cometly team. Cometly has been nothing but success for me since I joined. I've used other tracking software's in the past but they don't even come close to the performance and features Cometly provides. Every update so far has been an absolute game-changer to my success. Can't wait for all the new ones you have up and coming!"
