What's the biggest mistake you've made during a product launch?

Building features nobody asked for. Did it 5 times.

I was so sure my first idea was right (12 years in marketing gives you that kind of confidence) that I kept building what I thought people needed instead of what they were actually telling me. Each version, more features, more polish, then launching to a quiet room.

The real mistake: I was talking at users, not to them. I'd show a demo and watch for nods. Nods are free, they mean nothing.

What fixed it was treating product like ads. You don't guess the winning creative, you test 10 and let the data decide. Same with features. Ship the smallest version, see what people actually use, build from there.

If I relaunched today I'd ship uglier and earlier, just to find out faster what nobody cares about.

You lean launch-too-early or hold-too-long? I'm a recovering over-builder.

Treating distribution as a post-launch problem. We spent months building something polished and beautiful, then launched to near-silence because we'd assumed the product would speak for itself. It doesn't. Nobody wakes up thinking about your product.

The lesson that stuck: the distribution channel needs to be figured out before the product is done, not after. Now the first question I ask on any new feature is "how will people find out this exists?" If we can't answer it clearly, we either don't build it or we build the distribution mechanism alongside it.

The second mistake, honestly, was not being specific enough about who it was for. We thought broad appeal was a feature. It's not. Specificity is what makes people say "this is exactly for me."

Haven't launched yet but I'm already learning from threads like this before I do

My almost-mistake? Building for 3 weeks before talking to a single potential user. I thought the product would speak for itself. It doesn't. People do. Talking first, building second is the lesson I'm taking into my launch next Thurday.

posted my biggest forum thread in the wrong p/ on day one. spent two hours refreshing wondering why nobody was clicking. moved it to the right forum and got 4x engagement in the next hour.

lesson: read the forum description twice, post once.

real mistake was waiting to figure it out organically instead of just asking someone.

Launching the feature list instead of the one problem. Early on I'd show everything the thing could do, and people bounced because they couldn't tell what it was actually for. The launches that worked led with a single painful job and let the rest be a pleasant surprise.

I'm about to find out whether I've learned that. DukieX launches on Product Hunt Wednesday, so ask me again Thursday. Founder here, so fully biased about my own lessons.

One mistake I see a lot is polishing the launch page before pressure-testing the first workflow.

A clean page helps, but if people still ask “what do I do first?” the launch traffic does not convert into useful feedback.

I think the better prep is to make the first use case painfully clear, then have answers ready for the obvious objections: who it is for, what makes it different, what it costs, and what happens if the first result is not good.

Waiting too long because we want it to be perfect.

But there is no “perfect” launch.

The real learning starts when people actually use it, ask questions, misunderstand things, or ignore the parts we thought were important.

I’d rather launch with something clear and usable, then improve fast based on real feedback, than spend months polishing assumptions.

· no gtm strategy

· cramming too much info in a pitch deck (later solved this by revising it based on 1752 pitch analyzer)

· not understanding customers' demand well enough

Biggest one for me was assuming that once people started signing up, keeping track of them would take care of itself. It did not. Every new user was another thread to follow, another question to answer, another small commitment to remember, and none of that showed up in any launch checklist I had prepared. I had a plan for distribution and no plan at all for what happens to my own attention once distribution actually worked.
