I don’t think targeting a single influencer is really that valuable, but targeting a platform seems to work really well.
DXracer chairs have heavily targeted twitch streamers and I think that’s the main reason behind their success, because they are really expensive and uncomfortable, yet every teenage room of every colleague of mine houses one.
Of course that’s completely anecdotal, I just couldn’t help laughing at my own daughter when she bought hers. Because it’s a really horrible product with an insane price tag that only sells because everyone has one.
