The SaaS launch checklist that ships

Who this checklist is for

You are building your first SaaS product, solo or with a co-founder, and you want a pre-launch sequence that ends with paying users, not just a deployed app. This checklist covers the path from problem validation to a public launch.

What it takes

Cash costs are low: typically $100 to $500/month in tooling (hosting, email, analytics). The real cost is time, expect roughly 2 to 6 months from validation to launch for a tightly scoped MVP. The hardest part is scope discipline: shipping the smallest product that someone will pay for, instead of the product you imagine at year three.

How the checklist flows

Validation before code: "Define target user persona" and "Validate problem with 10 potential users", ten real conversations kill or confirm the idea faster than any amount of building. Then scope it: build the MVP feature list, and cut it in half. The build phase wires the machine: "Set up Supabase / backend", then "Define pricing tiers" (2 to 3 tiers, one clearly recommended) before billing, so "Set up Stripe billing" has something honest to charge. A landing page collects signups while you build, and analytics plus transactional email make sure launch day produces data and deliverable receipts, not anecdotes. The finale is operational, not theatrical: "Deploy and test the production app" end to end with a real card, then "Publish legal and support pages" so the first stranger who pays has terms to read and somewhere to write.

Mistakes that sink first-timers

• Building for months before talking to a single user, validation is step one, not a post-launch survey
• Launching without billing wired up, then discovering "interested" users vanish when a price appears
• Betting everything on launch day; sustainable SaaS growth comes from a repeatable channel, not one spike

Real-world examples

• Loom (launched as Openvid) went live on Product Hunt in 2016 and pulled roughly 3,000 signups in its first 24 hours, an early-traction moment the team later credited on its path to a $975M acquisition by Atlassian.
• Notion also drew early traction from Product Hunt (it topped the charts on launch), but other bootstrapped SaaS reached their first users very differently, Zapier, for one, spent months hand-recruiting paying beta users in other products' support forums. A launch platform is one channel, not the only one; treat a launch as validation, not a growth plan.
• The repeatable bootstrapped-SaaS pattern is to get a working signup flow, Stripe billing, and a landing page live before launch day, so the traffic spike converts instead of leaking away.

From a founder's point of view

A launch feels like a fireworks moment but it behaves more like a readiness test: whatever is half-finished on launch morning is exactly what breaks under the first real traffic. The founders who get the most out of a launch treat the date as a forcing function to finish onboarding, billing, and analytics, not as the goal itself. Attention is cheap to lose and expensive to earn twice, so the day matters less than whether the product can hold the people it attracts.

Your first milestone

Your first paying customer you have never met, a stranger who found the product, understood it, and entered a card. That is product-market signal money can't fake.
