Great team to work with. Deep expertise across MMM, LTV and MTA. Biggest win for me is the team is delivering high-value, auditable work that drives results - not a black box presentation for CMOs where no one looks under the hood and a real focus on making sure the outputs actually get used!

Rupali Singhal
Head of International Marketing Analytics
I had the pleasure of working with D1 when they implemented experimentation & analytics solutions to help us measure our branded content activities. They are super knowledgeable about Marketing Analytics and were able to translate complex solutions that we could all understand
