03 / ACQUISITION

Where do users come from?

4,522 visits in September, 94.91% from the US, declining steadily from 15,188 in July (-52.6% month over month). Direct 65.5%, search 25.9% with brand keywords at 91.4% (gothamloop and misspellings); social 5.2% from Reddit, YouTube, LinkedIn; new users mostly saw it discussed in job-seeker communities and then searched for it.

Channel share, initial acquisition, and growth drivers are distinct; correlation does not imply proven causation.

04 / YOUR NEXT QUESTION

What remains to be verified?

The following are research questions, not established market opportunities.

  • What do target users actually pay for? Is there direct user feedback or paid interview evidence?
  • Are these historical prices still active today? What are the conversion, retention, and fulfillment costs?
  • Is the "Social media" channel still viable? What resources do indie devs need to test it?
  • Whose needs are competitors failing to meet? Find specific evidence before deciding on your angle.

05 / BUSINESS EVIDENCE
