I'm not dismissive of businesses like Lemlist, but would propose another angle.

I find that businesses that are spin out from agency models are particular, inherit a strong characteristic and outlook similar to agencies. This is not a critique of their model per say, but an observation that leads me to be hesitant to take advice from agency-born models and apply to more typical product-focused B2B or B2C settings.

This leads me also to note that that the nature of content exposes us to a lot of people who believe in posting content. I'm not against it, but would like to fight the common urge towards content as the best strategy to go to market. However, given that the medium is message, we don't hear from people who don't need to post to do business.
