Freemium sounds like a growth hack. Free users → paid conversion → hockey-stick revenue curve. Reality? Most SaaS freemium models hemorrhage cash before hitting conversion velocity.
The math is brutal. Free users are expensive. They demand support. They test your infrastructure. They occupy seats that could go to paying customers. You’re subsidizing their learning curve while they decide if your product matters.
Dropbox proved freemium works. For Dropbox. They had product-market fit, viral adoption mechanics, and unit economics that could survive free users long enough to monetize. They’re the exception freemium sellers cite. Meanwhile, 95% of SaaS that copy the Dropbox playbook fail—because they don’t have Dropbox’s margins, network effects, or retention profile.
The real cost:
Your CAC ceiling drops. Free users have infinite churn tolerance. They convert at 2–5%, leaving 95–98% as dead weight. When you’re burning $3K/month just hosting their accounts, that 3% conversion rate means you need $100K in annual revenue per free user acquired. Most can’t hit it.
What actually works:
- Freemium as retention, not acquisition. Launch with a $29/mo floor. Run freemium only for existing customers who want to expand teams. Keep CAC low, LTV high.
- Free trial (14 days, credit card required). Converts 3–5x higher than freemium. Forces intent. Separates buyers from browsers.
- Generous free forever tier for 1 user, 1 project. Narrow, explicit limits. Make it valuable enough to stick, tight enough that paid is obvious.
- PLG + sales hybrid. Free tier drives virality, sales team closes annual deals. Works for Slack, GitHub, Figma.
Pick the model that matches your unit economics—not the one that sounds like growth.
