Day1Data helped us move from siloed data sources to a more scalable, automated data foundation. They aligned our teams around consistent KPIs, connected our core data sources into BigQuery and built a validated semantic layer we can trust. It has given us a stronger base for reporting, decision-making and AI use cases.

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

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!

Day1data has been revolutionary for Twilio. We now have a steer on the reasons for our sales performance & the marketing contribution to revenue. This has helped us spend much more efficiently
Rupali Singhal
Twilio, Head of International Marketing Analytics
We chose D1D over the others because I didn't want to get locked into yet another platform that wouldn't give me a custom solution & I wanted a better way to measure attribution than GA4. We love working with Day1!
