What should you do hour by hour on Product Hunt launch day?

Product Hunt resets at midnight Pacific Time (00:01 PT). Everything you do on launch day is measured from that moment. The founders who do well are rarely the ones with the best product — they are the ones who prepare the most and stay engaged throughout the day.

Here is the full hour-by-hour breakdown.

Quick answer: Post your product at 12:01 AM Pacific, write a personal first comment explaining why you built it, email your 30–50 person network immediately, and reply to every comment. The 8–10 AM Pacific window is when US traffic peaks and drives the most votes — treat it as a full-time job.

The Night Before

Final product walkthrough. Sign up as a fresh user, complete the core flow, confirm nothing is broken.
Pre-write all social posts, community posts, and personal emails. You will not have time to write during the day.
Set an alarm. You are staying up until midnight PT or waking up early.

12:01 AM Pacific Time

Post your product.

Do this yourself. Self-hunting is fully accepted and now the norm on Product Hunt. You do not need a "hunter" with a large following — that advantage has diminished significantly.

What your listing needs:

A clear, specific tagline (not "the best tool for X ever" — something concrete)
3-5 high-quality screenshots or a GIF/video of the product in use
A first comment from you (the maker) explaining why you built it and what makes it different. This is your most-read piece of text on launch day. Write it well.
Relevant gallery images
Links to your website and social

The first comment matters. It should tell your story, acknowledge the problem you are solving, and invite questions. Write 2-3 paragraphs. Make it personal and specific.

12:01 AM – 2:00 AM Pacific

Post in founder communities (Discord, Slack groups) where it is appropriate to share launches.
Send your personal email to your close network (the 30-50 people you prepared before launch day). Keep it personal — not a mass blast. Explain what you built and ask them directly to upvote if they find it interesting.
Reply to the first few comments on your PH listing. Engagement in the first hour signals to the algorithm that your post is active.

6:00 AM Pacific

The US East Coast is waking up. This is when traffic accelerates.

Post on X. Include your Product Hunt link, a screenshot or short video, and your launch story in 1-2 sentences. Use the "I built this" format — it performs better than pure promotional framing.
Post on LinkedIn if your target audience is there.
Check your position on the Product Hunt leaderboard. Do not obsess over this — it will fluctuate throughout the day.

8:00 AM – 10:00 AM Pacific

Peak US traffic window. This period accounts for a disproportionate share of daily votes.

Reply to every comment on your PH listing. Every single one. This keeps the post active and shows you are engaged. It also gives undecided visitors social proof that the founder is responsive.
Post in any relevant Reddit subreddits where product posts are allowed. Use the community's preferred format (many subs prefer honest "I built this" posts over marketing language). Read the rules first.
Post in relevant Slack and Discord communities for your target audience (not the same founder communities you posted in at midnight — different communities, relevant to your users).

12:00 PM Pacific

Mid-day check-in.

Review comments and reply to anything you missed.
If you have received any user feedback, acknowledge it publicly in a comment — it shows responsiveness and gives undecided voters a reason to trust the product.
Post a mid-day update on X ("We are currently [X on the leaderboard] — thank you everyone who has supported so far. We are here all day for questions.").

2:00 PM – 4:00 PM Pacific

Second US traffic wave. West Coast is fully online.

Continue engaging with every comment.
If there is a specific piece of criticism or a recurring question, address it in a dedicated comment thread. Turning a concern into a transparent conversation shows confidence in the product.

6:00 PM Pacific

The final push window. European users are done for the day; US users are finishing work.

Post a final push message on X and to relevant communities.
Send a quick follow-up note to your personal network ("It is the final few hours — if you have not upvoted yet, it would mean a lot."). Only send this once, to people who have not yet engaged.

11:00 PM Pacific

Check your final position.
Screenshot the results.
Write your post-mortem — what drove traffic, what drove upvotes, where conversion fell short.

48 Hours After Launch

Send a follow-up email to your waitlist/signups from launch day. Share the results ("We hit #X product of the day, got 400 upvotes, and 200 new users"), thank them for the support, and give them a specific CTA (sign up, upgrade, or share).
Post a launch recap on X and LinkedIn.
Submit to 20-30 directories if you have not already — launch day traffic is real but directory backlinks compound over time.

What Not to Do

Do not buy upvotes or use vote exchange groups. Product Hunt detects and filters these. It tanks your ranking instead of helping it.
Do not spam communities with identical posts. Personalise each post for each community.
Do not go dark during the day. Founders who disappear after posting get fewer votes than founders who stay engaged all day.
Do not treat the launch as the end. It is the beginning of a distribution effort, not the peak.

Frequently Asked Questions

Do you have to stay up until midnight Pacific Time to launch on Product Hunt?

Yes, if you want maximum launch time. Product Hunt resets at 12:01 AM Pacific, and products that post early have the full 24-hour window to accumulate votes. A product posted at 8 AM Pacific has already missed 8 hours of the day. If you are in a timezone where midnight Pacific is inconvenient, set an alarm and post from your phone — the listing just needs to go live, you don't need to be fully operational until the US East Coast wakes up around 6 AM Pacific.

How do you write a strong Product Hunt first comment as the maker?

Write 2–3 paragraphs covering: why you built this (the specific personal problem that motivated you), what it does and who it's for, and what makes it different from existing options. This is your most-read piece of text on launch day — more people read the first maker comment than any other part of your listing. Make it personal, specific, and honest. Avoid marketing language. End with an invitation for questions — it's the most reliable way to generate early comment engagement.

How many personal emails should you send on Product Hunt launch day, and to whom?

30–50 personalised emails to people who know you or your work — former colleagues, early users you've spoken to, online connections from communities you participate in, fellow founders. These should not be bulk emails or cold contacts. Each email should be short, personal, and ask directly: "If you find it useful, I'd really appreciate an upvote." A personalised ask to 30 people drives more votes than a mass email to 300 strangers — Product Hunt's algorithm also filters activity that looks like coordinated mass voting.

What should you post on X during your Product Hunt launch day?

Post three times: at 12:01 AM Pacific when you go live (the launch announcement with a screen recording or screenshot and your PH link), at 6 AM Pacific when the US East Coast wakes up (a "we're live" post with early traction numbers if you have them), and at the 6 PM Pacific final push window (a short "last few hours" post). Each post should tell a specific part of the story — the problem, the build, the early results — rather than repeating the same "go vote for us" message.
