I saw another founder market his startup with a YouTube channel. His strategy is to provide genuine advice about the space in general including on how to effectively use his competitor's products. It seems like a really good strategy so I decided to start a channel on personal knowledge management.
I don't plan to talk about my competitors products as much (though that seems to be the "growth hack"), but I do plan on talking about general practices that have helped me with PKM.
My views are a bit contrarian. My first video is on how inbox zero is useless (https://www.youtube.com/watch?v=zRx8pzgcp_8) which is not what most productivity gurus say. Time will tell if this helps bring traffic to Dynomantle or not.
