For two reasons: the review gives me an extra seat (AppSumo vendors stimulating reviews are always appreciated by the community, as is evident from the 200+ reviews here), and I really like the tool.
I have used LinkedHelper in the past, which was clunky and is Russian, and I recently ran into LinkedIn blocks using SalesQL with SalesNavigator.
Waalaxy seems to be working fine. The endless use of animated GIFs and the silly names for the scripts are infantilizing and distracting, at least to me, but probably fun for clients with ADHD. Otherwise this tool seems to be super flexible. I have some issues/requests, but as it is Easter Monday in France - and the French like their vacations, we'll have to wait for their reply until tomorrow.
In the mean time their bot asked me to review the tool on AppSumo, and since my first leads are coming in, I am happy to recommend them.
