Great firm for your demand generation needs. They have a wide range of services that they helped our company with. We were really happy with the results we got, and the team was awesome to work with. Super communicative and did an awesome job.

As a CEO you have limited time to write creative, do market research and post consistently on LinkedIn and other social channels. Vlad and the team helped myself and CitrusAd become a PR powerhouse and thought leader in the Retail Media space through well curated research and a deep understanding of how I personally wanted to be represented. It’s a collaboration though. People who think that just paying money and outsourcing lead gen gets you business are kidding themselves. Belkins provide direction and execution. It’s still up to the client to work out their audience needs most, what’s working and what isn’t. Most companies fail in outreach because they haven’t actually solved a genuine problem or the product market fit is not ready. Would use again any day!

They really know what they are doing in terms of cold email and lead generation.
By Stephen S.
The pressure to join was intense. I have yet to see one lead that has been any good. I had very strong feelings about saying no, but the pressure was on. I blame myself, but I will never again fall to pressure again. And, I’ll never recommend them to another agent.
