Day-1 of growing my SaaS from $0 to $100 MRR (No promotion)

It's been a month since I built my SaaS.

So far:
- 250+ users
- 110+ projects created
- \~$18 in total revenue

I've spent most of my time building, shipping updates, and iterating on the product. I initially offered a lifetime deal, which I've now removed. Now I'm shifting my focus from building features to marketing and getting paying customers.

Currently, I promote on X and YouTube, but most of my traffic comes from AI search, especially ChatGPT. For those who've grown their SaaS from scratch, what marketing channels would you recommend I focus on next? And what would you do in my position to get the first few paying customers?
