“Expert CRO support with seamless integration”

When Diptyque Paris began our CRO program, we lacked resources to meet our goals. EchoLogyx quickly impressed with their professionalism and seamless integration. Their unmatched test development skills go beyond execution, they bring valuable ideas. Weekly catchups are efficient, collaborative, and genuinely something our entire team looks forward to.

“Flawless testing, zero QA issues—amazing!”

Really appreciate the Echologyx team. They've absolutely crushed it since day one. All of the testing so far has been flawless, and I seriously don't think I've ever gone six months in a program before where there hasn't been even one QA issue with a live test. I'm amazed and super grateful to the team. It makes Chirpy look awesome in that regard.

“Turning CRO ideas into live tests, fast.”

Love working with them. They make my work as a CRO Specialist much easier! I think of a new A/B test idea and debrief this to EchoLogyx. In no time, this idea is developed, and I can start testing. We already completed a lot of successful tests this way!

“From ad hoc to sprint-driven efficiency.”

In the last couple of years, I have been working very successfully with EchoLogyx. We moved from Ad hoc cycles to sprint cycles. EchoLogyx was instrumental in helping us do that. The efficiency we gained working with them has helped us, helped book more work for our clients. Very professional, hard-working. Efficient in a way we can rely on them.

“Distance-free collaboration you can trust.”

I have to admit, I was hesitant about using an AB testing full stack development firm that wasn't located in Canada - time difference, communications, were top of mind. But as we've gone through this process, my apprehensions are 100% gone. The team has dealt with myself and our client with professionalism, and always approached a challenging situation with a "can do" attitude.
