The 18 rules for building SaaS in 2026

Provide Google login: The majority of people wouldn't create an account otherwise.
Charge immediately: Stay away from free trials. Paid users = serious users.
Launching is the start not the end: Post-launch is 4/5 marketing, 1/5 product.
Promote shamelessly: Plug in your product everywhere, not just where it's "safe".
Value the unsubscribers: They're giving you the most valuable input.
Use your own product as much as you can: You'll find bugs your users haven't reported yet.
Retention > acquisition: The most valuable revenue comes from existing users.
Cut your MVP in half: Then cut it again. Ship the core, nothing else.
Think bigger: $10k/month feels great until you realize $100k requires the same effort.
Pay attention to market: If it's not converting after real attempts, the market is telling you something. Listen.
Distribution before features: A product nobody discovers is a product nobody uses.
People buy outcomes, not software: Sell the result, not the feature.
Measure behavior, not compliments: Revenue and retention matter more than praise
Make the first win happen fast: Users should experience value within minutes
Don't build for everyone: The narrower your audience, the stronger your message.
Your landing page has 5 seconds: Clean, fast, obvious value prop or they're gone.
Talk to your users: Email your users. DM them. Get on calls.
Price based on value, not competition.

Most SaaS founders fail because they give up too early
