Any successful entrepreneur out there who turned himself/herself as their sales strategy. Would like to hear what strategies you followed.
what do you mean specifically?
I mean how they use their thought leadership to sell the product
If you already have 100k followers it's pretty easy to create something (anything) and sell it for $50-$100 to 0.5%-1% of that audience and make good money. And you can keep doing this, or sell a service instead.
What is your question exactly?
One of the more popular examples of this in Saas is how Neil Patel did this with UberSuggest: https://neilpatel.com/ubersuggest/ (granted he acquired the tool and then associated his personal brand to it).
Yes right!
