The Conversion Funnel
The career lifecycle creates a natural journey: Resume -> Apply -> Prepare -> Interview -> Get Offers. Free tools handle the first three stages. The switch to paid feels natural, not forced.
The Economics
Each free tool costs .02-0.05 per use in LLM API costs. Compare to Google Ads: -15 per click at 2-5% conversion = -750/customer. Free tools: 100-1500x cheaper acquisition.
See pricing - free plan includes 3 AI responses/day forever.
Lessons for SaaS Founders
- Make free tools genuinely useful, not crippled demos
- Each tool should solve a complete problem
- The jump to paid should feel natural
- SEO benefits compound (each tool page ranks for its keywords)
