I'll be upfront that I'm not the one in the tool every day. What I care about is whether a small team can run a serious amount of advertising across a lot of markets and still feel in control of it. That's where we are now, and it wasn't true a year ago.
We parted ways with our agency earlier this year and moved everything in-house onto Adbrew. The biggest change for me is that I finally get the whole picture in one place, not just the advertising slice chosen to look good in a monthly report. Sponsored, DSP, and what's actually happening on the shelf (buybox, availability, profitability) all show up together, so I'm judging us on total sales. Our blended return on ad spend has been climbing steadily since we made the switch.
Two things have gone better than I expected. The first is Amazon Marketing Cloud. We had access to it before but it just sat there, because nobody in the business could write SQL or knew where to start. Our team now builds audiences and reports from pre-built models that just work, and puts them to work in display campaigns, without hiring anyone to make that happen. The second is the automation layer. The system handles the routine work, but what I appreciate is that the team isn't just handing everything to a black box. They've built their own rules on top of the AI where they want that control, and for everything else, the AI takes care of it. That flexibility is what actually got buy-in internally.
The support has also been genuinely good. They stayed close through a messy handover from our old setup and haven't gone quiet since. That's rarer than it should be. Review collected by and hosted on G2.com.
It rewards people who already understand Amazon advertising and it will overwhelm someone who doesn't. Review collected by and hosted on G2.com.
