Double Takes

A startup's launched after a new product in record time after Test Double's product coaching. Kudos to Jen Tedrow for her workshops that also unveiled a $2M product idea!

Tammy Lawlor's strategy enabled a global retail client to align their portfolio, boosting product releases from quarterly to 2x monthly (!) and launching two new products plus key enhancements.

Gusto's legacy Rails upgrade succeeded with our consultants leading the charge, fixing 1,700 test failures -- all without disrupting daily operations and completed on time and under budget. Cheers to Steve, River, Daniel, Will and Jake!

We collaborated with client leadership at a popular magazine to implement a culture of data-led decision making — which led to millions of dollars saved or generated. Shout out to Zack Kelly, who identified an e-commerce checkout error causing up to $7 million (!) in lost revenue.

Joé Dupuis audited and simplified Treehouse's AWS infrastructure, cutting costs by 25% and reducing infrastructure from ~40 servers to 3 servers + serverless ECS cluster. Why pay for complexity you don't need?

Shout out to DevOps pros Keith McCanless and Jessie Puls, who empowered dev teams at Mode to quickly and easily deliver both their own infrastructure needs!
