How we helped a small SaaS go from $0 to $15k MRR in 3 months (no ads, just growth hacking)

Bootstrapping a SaaS is not easy. We recently helped a Q&A app to gain early traction, and instead of jumping into ads or paid promos, we decided to use a lean growth method, more hands-on and out of box approach.

Got the basics right
We worked on clear messaging, product positioning, a short demo video, and added simple tools like Smartlook and rb2b to understand user behavior. No fancy setup, just enough to get feedback and make changes fast.
Identified traffic channels, searched where users and competitors hang out
Reddit and IndieHackers were gold. We didn’t promote, just helped where we could.

In parallel, we added a small Q&A section on the website, a chatbot to answer common questions and keep users engaged, and guides on how to get started. That actually helped SEO more than expected.

AppSumo launch
It gave us some early traction and credibility. Not a huge moneymaker, but it got people using the product and sharing thoughts.
Founder led content strategy on LinkedIn
The founder shared behind-the-scenes stories. This wasn’t easy to kick off but some posts got attention, and a few good leads came from that. Slower channel, but high intent.
Reached out to vibe coders for fremiums
We noticed vibe coders needed this most, from the comments and reviews we gathered previously.
How did we find them? Used boolean search on LinkedIn, sent warm outreach offering fremiums, no pitch, no sales no spam.

Result? User generated content, reviews on G2 started pouring in and referrals started to come in.
6. Next step is Product Hunt
We’re not rushing it. Planning to launch once we have more of a base and community support. No point doing it just for a spike.
We’re still learning, but this approach with small steps, consistent feedback, and staying close to users helped us grow without burning money.
Hope this helps someone else in the early messy stages. Happy to chat if you’re figuring it out too.
