Theodo allowed Immediate Media to hit the ground running and have been fantastic. We couldn't have moved at the speed we did without them. I looked forward to my daily interactions with the Product team, as they were always productive and good fun!

Steve Wright

Head of Mobile, Immediate Media

The switch from full speed feature delivery to managing live deployments was seamless, and a testament to our close collaboration. Theodo stepped back and allowed us to take the reins which was expertly managed. The team utterly smashed it.
