From zero to first customers in 90 days — a SaaS launch playbook

The 90-day mindset

Most SaaS products fail because they never launch. The builder spends 6 months perfecting features nobody asked for. The 90-day approach flips this: validate fast, build an MVP, launch, and iterate based on real feedback. Perfection is the enemy of progress.

Days 1–14: Validate your idea

Before writing code, make sure someone wants what you're building. Talk to potential users. Post in communities. Create a simple landing page with a waitlist. If you can't get 20 people interested before building, reconsider the idea.

Good validation signals: people ask "when can I use this?", they share it unprompted, or they offer to pay before it exists.

Days 15–45: Build your MVP

An MVP is the smallest version that solves the core problem. Use a boilerplate to skip the boring parts — auth, payments, emails, deployment. Focus 100% of your time on the unique value your product provides. Ship ugly, ship incomplete, but ship.

• Use a proven tech stack: Next.js + Supabase + Stripe (see our SaaS guide)
• Don't build features you don't need yet
• Deploy to Vercel early — show real progress

Days 46–60: Launch publicly

Pick a date and commit. Post on Product Hunt, Hacker News, relevant subreddits, X/Twitter, LinkedIn, and Indie Hackers. Write a short "why I built this" story — people connect with stories, not feature lists. Ask early users for testimonials.

Days 61–90: Grow and iterate

After launch, focus on two things: retention (are people staying?) and acquisition (how do new people find you?). Write blog content targeting search queries your audience uses (SEO guide). Collect feedback aggressively. Ship improvements weekly.

The goal by day 90: at least a few paying customers and a clear signal that the product has value. From there, you compound.
