Hi!

I’m Elliott.

As the Principal of Media and Measurement, my focus is on paid media, e-commerce and emerging martech.

Before Part and Sum, Elliott consulted for global brands from his base in Tokyo while launching and scaling his own e-commerce channels from $0 to millions in revenue, achieving endorsements from Ariana Grande along the way. Elliott’s initial exposure to marketing came via music where he performed as a session drummer touring worldwide from Paris to Shanghai, collaborating with Pharrell, doing events for Audi and H&M, with work featured in Vogue and The New Yorker.

Beyond finding product market fit, it’s essential to balance media investments with realistic goals so that you don’t overcommit to targets that are too aggressive. Scaling media campaigns is a balancing act between making sure that you’re not missing out on acquisition opportunities while ensuring that each channel is driving incrementality. As the privacy landscape becomes increasingly difficult to prove direct response ROI, KPIs like marketing efficiency ratio and measurement tactics including dark market tests and causal impact studies are becoming instrumental to prove the value of media investments.”
