Built tools for freelancers, now wondering about next steps.

Last year I lost too much money and time chasing fake jobs and working with clients who disappeared after weeks.
Out of frustration, I built two small MVPs:

• IsThisJobLegit – paste a job ad and it flags scam patterns
• ClientFlagger – check a client’s reputation (and add your own experience)
  They’re live and people use them, but I’m hitting a wall. Building was the easy part, getting traction is way harder.
  Right now:
• A few freelancers testing
• 0 real growth engine
• Struggling with visibility outside small communities
  I’m curious: for those of you who launched small niche tools, what worked better for early traction — consistent content, partnerships, or cold outreach?
  Would love to hear how you approached the “no audience, no budget” stage.
