Freemium sounds like the safe choice. For most indie SaaS products, it is the expensive one. Here is when freemium works, when it doesn't, and how to decide.
Every solo founder considers freemium at some point. It feels like the low-risk path — let people try before they buy, build a user base, convert them later. The reality is that freemium is one of the most capital-intensive business models in software, and almost all of the solo founders who succeed avoided it.
Freemium feels like a distribution strategy. It is actually a cost centre with a conversion problem attached. Every free user costs you infrastructure, support time, and product complexity. The conversion rate from free to paid in most B2B SaaS products is 2–5%. That means 95 out of every 100 free users cost you money and give you nothing in return.
The founders who succeed with freemium are not the ones who thought it was safer than charging — they are the ones who had a specific, structural reason why free users make paying users more valuable. That reason is usually viral growth, network effects, or a product that genuinely requires critical mass to work.
Viral growth: free users recruit paying users through natural product usage. Slack, Notion, Dropbox — free users share with colleagues who need the paid tier to collaborate. Without the viral loop, the free tier is just a cost centre.
Network effects: the product becomes more valuable as more people use it, and free users contribute to that value. Marketplaces, communication tools, and platforms with user-generated content sometimes fit this model.
Land and expand: free individuals in an organisation lead to paid team or enterprise contracts. Only works if your product has a natural team use case and your sales motion supports it.
Most indie SaaS products have none of these characteristics. A scheduling tool for therapists, a contract management app for freelancers, an inventory alert system — none of these are more valuable because of free users.
Freemium fails when: your product solves a problem for individuals rather than teams, there is no viral or network mechanism, your conversion rate from free to paid is below 5%, your support burden from free users exceeds their lifetime value, or your infrastructure costs mean free users cost you money from day one.
The additional failure mode specific to solo founders: free users give you the wrong feedback. A free user who would never pay tells you what they want in a product they're not paying for. Their requests shape your roadmap in ways that don't serve your paying customers.
For most indie SaaS products, a 14-day trial with a card required is the correct alternative to freemium. It gives serious customers a full evaluation window. It filters out users who are not serious enough to enter their card. And it converts at 15–25% — five to ten times the freemium conversion rate.
The card requirement is not a friction point for your target customer. It is a filter. A customer who won't enter a card for a 14-day trial of a product that could solve a real problem for them is not a customer who will convert from freemium either.
Answer three questions: Do free users make the product more valuable for paying users? Is there a natural viral or network mechanism? Can you sustain the infrastructure and support cost of a free tier for 12 months before seeing meaningful conversion revenue?
If you answered yes to all three: freemium is worth testing. If you answered no to any of them: start paid with a time-limited trial and save yourself 12 months of subsidising non-customers.
