Why O-CMO Reviews exists and how we collect reviews

O-CMO Reviews gathers, in one place, what clients have publicly said about working with O-CMO, the marketplace of verified Fractional CMOs for tech companies founded by Yaroslav Lehenchuk in 2023.

Our rules

• Only reviews already published on an independent platform or in a public case study are listed.
• Quotes are reproduced word for word. We do not edit wording, combine sentences or translate without saying so.
• Every review links to its original source, so anyone can check the reviewer, date and full text.
• Where O-CMO has a business relationship with a reviewer beyond the engagement (for example, both companies reviewed each other on Clutch), the review page says so.
• If you find a review about O-CMO that is missing here, positive or critical, email team@o-cmo.com and it will be added.

Who runs this site
