How I stopped marketing in the dark by building my own growth team

Building a SaaS project usually feels like building in the dark. As a solo founder, I spent too much time switching between SEO tools, strategy docs, and social media dashboards. I was constantly facing the blank page and wondering if anyone actually cared about my updates. I did not want to hire an agency, so I built PostMine.

My goal was simple. I wanted a growth co-pilot that understood my project from the inside out. Instead of manually auditing every page or hunting for keywords, I started by feeding my project URL into an automated system. It now performs the SEO and GEO audits for me and generates competitor dossiers to help me see where I actually stand.

Content creation was the next hurdle. I realized that generic posts do not drive growth. I trained the model to write in my specific brand voice, ensuring every post on X, LinkedIn, and sounds like me. Now, the platform identifies active discussions on Reddit and Hacker News where my potential users are already asking for solutions. It turns my day-to-day work into a stream of relevant replies.

I built this to skip the manual work of managing multiple tools. Whether you are a solo founder or an indie hacker, you can try the free version at https://postmine.tech to see how it changes your workflow. You get one fresh post and one daily reply opportunity to start.

I am still iterating on the winner-mining structure to help founders find what works faster. Building this has moved me from guessing to executing. You can follow my progress as I continue to ship updates.
