The SaaS Founder's Launch Day Checklist (2026)

A SaaS launch without a checklist is a launch where something gets forgotten. Not the product — the product is usually ready. What gets forgotten is the video, the follow-up thread, the cross-post to LinkedIn, the reply to the first ten comments. This SaaS launch checklist covers the 48 hours before, the morning of, and the first hour after you go live.

48 hours before launch

• Write your launch tweet. One hook line, one sentence of what it does, one CTA. No thread yet.
• Take a fresh screenshot of your hero section. This is the visual for your launch video and your OG image.
• Generate your launch video. Paste your landing page URL into saasclips, pick Launch style, download the MP4. Takes under a minute.
• Draft your Product Hunt listing if you are posting there. Gallery image, tagline, first comment.
• Write a short thread (3–5 posts) that goes deeper after the launch tweet: the problem, what you built, how it works, what is next.
• Schedule a LinkedIn version of the launch post. Same video, shorter copy.

Launch morning

• Post to X first. Native video upload, not a link. Square 1080×1080 fills the column.
• Post to LinkedIn within the hour. Same MP4 works natively on LinkedIn feed.
• Submit to Product Hunt if planned. Do it at 12:01 AM PST for a full day on the leaderboard.
• Post in any communities where you have standing: Indie Hackers, relevant Slack groups, Discord servers. Paste the tweet link, not a fresh post.
• Pin the launch tweet on your profile.
• Reply to every comment in the first two hours. The algorithm rewards early engagement.

First hour

• Post your thread as a reply to the launch tweet. This extends reach without splitting it.
• Share your Product Hunt link in the launch tweet thread once it is live.
• DM five to ten people who have expressed interest and let them know it is live. A personal message beats a blast.
• Screenshot any early traction and save it. You will use it in a follow-up post.

Follow-through (days 2–7)

• Post a “what I learned on launch day” update. These perform well on X and build audience for the next launch.
• Re-render your saasclips video with the Carousel style for a second post that walks the feature list.
• Reply to late comments. People discover posts days after they go live.
• Update your SaaS launch checklist with anything that worked or did not work this time.

The one step most founders skip

The launch video. It takes longer than the tweet and shorter than anything else on this list. A SaaS launch checklist without a video is a checklist that leaves the most visible part of the post to chance.
