I am a technical founder and has the same mindset a year ago (I can’t sell, I don’t know how to market … etc).
Reality is, you’re the only one who can do these things at the early stage. It doesn’t have to be complicated or a go-to-market plan. Ignore all these jargons for the time being.
Here is a simple way to start:
1) what is the problem you’re solving?
Describe the problem in a few sentences, then search for keywords and see what people are searching for for those keywords. A good cheap tool to start with is keywords anywhere.
Then write quick blogs about the problem. Those blogs don’t have to be a 1000 words one. Even some quick ones will be enough to generate some traffic.
2) Who will benefit from your solution?
Whether you’re a B2B solution or a B2C, you need to test different channels (platforms) where you think your potential customers are.
You can post on Twitter, LinkedIn, instagram, Reddit … etc. see which one will bring more engagement and focus on that channel.
