What our customers have to say about Diffblue Cover

Ali Alauoubiy, VP Engineering & Ops, ESW Capital

“ESW acquires leading software and SaaS companies on a regular basis and puts them through a rigorous 90-day process to evaluate and improve code and performance. Having already built a tool to review code and create unit tests, we knew we needed to turn to leaders to improve and automate our already robust tools and processes. Diffblue's Cover is our secret sauce.”
