Should you validate first or just ship?

The short answer: neither, the way most founders do them. On Reddit, “validating” mostly means posting an idea and asking other founders if they’d use it, and founders who started that way later posted a first customer 27% less often than founders who started by showing what they’d built, at the same number of posts. But building for six months and then showing people isn’t the answer either. The typical waitlist that opened its doors turned about 0.9% of its signups into paying customers. The one check that tells you much is asking a specific buyer for money, and in 290 validation posts I read by hand, not one founder had tried it.

I used every post since 2022 in seven builder subreddits (r/SaaS, r/SideProject, r/startups, r/indiehackers, r/Entrepreneur, r/microsaas and r/buildinpublic), already sorted into posts by people building something and what they were stuck on. I followed 32,898 founders from their first post to their later ones. Then I read 1,631 posts by hand: 400 “is this worth building?” posts, 400 posts that say how long the founder built before launching, 531 posts that give a waitlist size, and 300 that mention selling before building.

What validating looks like in practice

Of the 400 posts a model had labelled as validation, 290 were a founder asking whether their own idea or product had demand; the rest were advice, ads (often for validation tools) or people looking for an idea. Here is what those 290 founders had done to check, before or besides posting:

For 201 of the 290 (69%), the post was the whole check. 5 said they had talked to potential customers. Nobody had taken a deposit or a pre-order, and nobody had run an ad to see if anyone would click. Only 9 gave any number at all: signups, interviews, users or payments.

The questions follow from that. The most common was some version of “would you use this?”, in 120 posts; “would you pay for this?” came up in 29. 29% named a specific buyer, like independent dental clinics or Shopify stores past a certain size; the rest said “small businesses”, “creators” or “anyone who…”. And even the ones who named a buyer asked other founders, not the buyer. Across every validation post in the corpus the median got 2 comments, and 30.5% got none.

One more thing stood out. 32% of these founders already had a working version or a live product, and many of the unclear ones had been building for a while. A lot of “validation” happens after the building, as a request for reassurance.

Did asking first help?

I took the 32,898 founders with at least two builder posts whose first post went up before July 2026, so everyone had four months to post again, and sorted them by what that first post was. Then I checked whether any later post said they’d got a first customer or first revenue:

The founders who asked first came last: 3%, against 4.3% for founders who started by showing what they’d built. That could just mean they posted less, so here they are compared with founders who posted the same number of times:

The ask-first group is behind in every row. Put together, they posted 165 first customers where founders who showed first would have posted about 226 at the same post counts, 27% fewer. Against founders whose first post asked how to launch, it was 34% fewer. Giving everyone ten months instead of four made no difference: 27% fewer.

There’s a twist in the other direction too. Across all their posts, founders who ever posted a validation question look better than those who never did (4.6% against 3.7%), but they posted more (a median of 3 against 2). At the same number of posts, the ones who never asked are ahead in every row:

Why asking first goes with worse results

Two things in the data point to the same cause. First, asking tends to replace shipping. Of the 5,547 founders who started with a validation post, 45.8% later posted something they had built or launched (half within 29 days). The rest never did, in these subreddits at least. Second, asking repeats. 52.1% posted another validation question later, often about a different idea. A forum can always find a reason an idea might not work, so the cheapest thing to do with a lukewarm answer is ask about the next one.

And the people answering are the wrong people. A founder in r/SaaS saying “I’d use that” costs them nothing and commits them to nothing, and they’re usually not the buyer. I made the same point in Why is nobody using what I built?: asking a forum isn’t validation. This is the longer version of that finding.

Building for months first isn’t the answer either

So should you just build? Of the 400 posts that mention build time, 177 were a founder saying how long they built their own product before launching or putting it in front of users. The median was 6 months. Only 7 of the 177 said they had checked demand before building. Of the 88 that said what happened next, 35 had paying customers (often one or two), 25 had users but no revenue, and 28 said nobody came.

The numbers in each row are small, so read this as a shape, not a rate. But there’s no sign that longer building helped. Founders who built for under a month reported paying customers in 8 of 14 cases; founders who built for over a year, in 4 of 11. 20 of the 177 said they wished they had talked to buyers before building, including 11 of the 28 who said nobody came. The usual story: months of coding alone, a launch, silence, and only then the first conversations with buyers.

What a waitlist is worth

A waitlist is the most common step between those two: build a landing page, collect emails, and treat the count as demand. I read all 531 posts that gave a waitlist size near a word like paid, launched or converted. 335 reported the founder’s own list (median 100 signups), and 97 had opened the product to it. I checked 28 of those post by post where the founder said how many people on the list went on to pay:

The median list turned 0.9% of its signups into paying customers. Pooled, it was 2.7%. 10 of the 28 lists produced no paying customer at all, and 22 converted fewer than one in twenty. The big lists that did well came with work on top: one sent more than ten launch emails with testimonials and discounts (5.0% paid), another let people in slowly and onboarded them (8.0%), and a third filled its list with paid ads (3.7%) and then worked out what each customer had cost. Getting people to even try the product was hard too: across the 24 lists that said, the median share who signed up or used it after launch was 12.8%.

One founder whose 2,000-person waitlist produced five customers put it simply: an email “costs nothing so it signals nothing.” A signup tells you a headline worked, not that someone will pay. These are the founders who chose to share their numbers, so the true picture could be better or worse. But I found no case of a big waitlist converting well without the founder working the list.

Asking for money is the check that counts

Of the 300 posts that mention pre-selling or selling before building, 74 told the founder’s own attempt; most of the rest were advice or plans. Of the 49 with a result so far, 44 ended in paying customers. That tells you mostly that people write up the pre-sales that worked, so I won’t call it a success rate. The amounts were modest (a median of $1,000 where they said), and the most common route was a landing page with a real checkout rather than an email field.

What’s worth noticing is how the conversations went when the founder said how many people they asked. One sent 50 direct messages to people with the problem and got five payments before writing any code. Another asked about 50 people in their own network and three companies bought. A third gave three demos and got no pre-sales, which is also an answer, and a cheaper one than six months of building. A payment, a deposit or a signed pilot costs the buyer something, so it tells you something. That’s the difference between this and a forum reply or a waitlist signup.

So should you validate first or just ship?

The data says the choice is mostly framed wrong. Validating, as most people do it, is asking strangers for an opinion, and it goes with fewer customers, not more. Shipping, as most people do it, is months of building for nobody in particular, then a launch into silence. In the posts I read, the founders who got paying customers early mostly had one thing in common: a specific buyer saw the product, or an offer for it, early and was asked to pay.

So do the cheap version of both. Build the smallest thing that does the job, in weeks, and put it in front of the people who have the problem with a price on it. If you can’t build it in weeks, sell it before you build it.

What I’d do

1. Name the buyer before anything else. Not “small businesses”: a role, an industry and a size, specific enough that you could list 50 of them. 71% of validation posts couldn’t.
2. Ask them, not other founders. Go where your buyers already talk, or write to them directly. A founder’s “I’d use it” isn’t evidence unless founders are your market.
3. Ask for money, not opinions. A pre-order, a deposit, a paid pilot, or a checkout button on the landing page. “Would you pay?” is still an opinion. “Here’s the link” isn’t.
4. Build in weeks, not months. The longest builds in the sample did no better than the shortest. Ship a version that solves the one problem, and keep going from what buyers actually do.
5. Treat a waitlist as a list to sell to, not proof. Expect around one in a hundred to pay unless you write to them, more than once, with a reason to buy now.
6. Don’t hop ideas on a forum’s word. Half the founders who asked first posted another validation question later, often about a new idea. A lukewarm thread is not a verdict; a buyer saying no to a price is.

What I can’t tell you

These are Reddit posts. The outcomes are what people posted, not what happened to them, and most founders who quietly got customers never said so. The founder comparison is matched on how much people posted, which removes the biggest bias, but it’s still observational: people who ask a forum first may differ in other ways, like having less experience selling. And it tests validation as these founders practised it. Someone who interviews 30 buyers or pre-sells before building barely appears here, because they so rarely post about it while doing it.

The hand-read samples are small in places. The build-time rows have a dozen or two posts each, and the waitlist rates come from 28 lists whose founders chose to share them.

How I did it

The posts: every post since 1 January 2022 in the seven subreddits above, from the Arctic Shift Reddit archive, each sorted by a small model into whether the poster is building something of their own and what they’re stuck on. The method is in Building got easy. Getting anyone to care didn’t.

Founders: grouped by Reddit username, leaving out deleted accounts, with at least two builder posts and a first post before 1 July 2026 that wasn’t already a success post. “Later posted a first customer” is the phrase match from the first-customers research (“I got my first paying user”, “we hit $1k MRR”, about 85% genuine on a hand check). The matched comparison applies the show-first group’s rate in each post-count band to the ask-first group and compares the totals. “Later posted something they had built” means a later post labelled as showing a product or asking how to launch it.

The posts I read: 400 posts labelled validation, one per founder, picked at random; 400 posts that say how long the founder spent building, one per founder, picked at random; all 531 posts (one per founder) that give a waitlist number near a word like paid, launched or converted; and 300 posts mentioning pre-selling or selling before building. Each was read in full, and only numbers the post states were recorded. For the waitlist rates I left out lists that hadn’t launched, buyers who didn’t come from the list, one story posted under two accounts, and a copy-pasted promotion that appeared under three. I also left out five pre-sale posts that read like planted promotion for the same toolkit.
