Idea Validation

Ok, I am getting questions like how I came up with an idea of boost referral. So here are the details:
One of my resolutions for this year is to build at list 2 Micro SaaS Products.
Each of which can be made Under 2 Months & $5000 USD.
Already Setup the technical team of 4 Members, which encourages me to ship products real faster.
Considering these pros, My friend James shared a problem statement to grow his newsletter list.
We discussed the opportunity, market growth & finally decided to start building it.

I will share the very first Use Case we discussed during the early days.
