Stop Building Products Nobody Wants: The Validation Method That Works

8•Taikhoom10•4h ago
Hey HN, Recently I have been working on a couple startups in SF. And I have noticed talking to a lot of founders, since my target users are early stage founders, that they are hyper focused on building. Often they come up with a idea they think is great and can't stop thinking about it and just shoot out to build it. Often they might go months on long just straight building. And while building is extremely important, and being so passionate about is great. I have come to realize they often end up not really validating anything. So after a lot of testing and validation, and reading the "Mom test" of course, I think I know the best way to validate. Before you build anything, have a clear way to define what you are building, whip up a quick landing page and get people to pay. Show them demos, and really get the landing page in front of them. If people will pay before even building something, that is a great sign for you to go ahead and build as well a to investors. So yeah, I just wanted to put that out there, if anyone has anything to say let me know.

I've worked on enterprise products and that is nowhere near being an adequate simulation of the sales process.
Taikhoom10•4h ago
Yeah I didn't describe that in detail, but in short you explain your idea in your landing page, market it in front of your target users. If your able to convert without having anything built that shows strong demand for the product. Does that clear it up?
PaulHoule•4h ago
Where I work we sell subscriptions to (mostly) academic organizations. There is no way these people will go to a web page and subscribe with a credit card, instead they talk to our sales people multiple times, have to talk to other parts of their organization to get the money, often write a bespoke contract, etc.

Similarly I have worked for systems that would sell a highly customized system to a company like Airbus or Comcast or Safety-Kleen and there would be a huge amount of work going into determining what exactly gets sold which again, is not comparable to going to some landing page and paying with a credit card.

If you're selling mattresses or something, maybe that's different.

Taikhoom10•3h ago
I am talking about the realm of startups and products. And yeah some might be skeptic, but a lot of people would if they really could use it.

And that's just a metric you can use to really see if people are interested in your product.

PaulHoule•3h ago
The difference is "consumer product" vs "enterprise products". My current employer is certainly not a startup, but I have worked at startups (angel, venture-funded or pre-funded) that worked on enterprise products.

For consumer products what you're saying may make sense, but that is not the universe of all products and opportunities.

Taikhoom10•3h ago
Yeah I totally get what your saying. Do you happen to be working on a startup right now?
sidewndr46•3h ago
Did you actually read his reply or are you just working from some sort of script?
codingdave•3h ago
I had really hoped we were past the "landing page" concept at this point. Yes, if you can get people to pay, that validates the ideas, but a landing page is mostly a validation of the marketing, not the product. And it could be complete throwaway work because once the product hits user's hand, they will correct the details that are wrong, and your initial "landing page" is outdated instantly.

Better to talk to people and iterate on prototypes with a handful of pilot users until they are willing to pay, them expand beyond the pilot group. Not only it is real communication and iteration with users, we aren't spamming the world with "landing pages" of products that do not actually exist.

Taikhoom10•2h ago
Ok well, your right it is usually a combination of things, you can have several prototypes that you show. My point is you shouldn't get stuck in any of the i will build before validating.
Taikhoom10•1h ago
And also, unless you get feedback in the right way, a lot of people could mislead you. Paying shows real validation that you cant argue with. Actions are a lot louder than just words.
ashdev•3h ago
This might work for B2C startups, but not so much for B2B. In B2B, people need to see a working product that clearly saves them time or money. The sales cycle is longer, and landing page tactics alone usually aren’t effective.

A better approach is to talk to as many potential customers as possible early on. Collect emails, show a rough prototype, get feedback, and iterate. Then, when you’re ready to launch, go back to those same people, email them, show what’s changed, and demo how the product delivers real value.

Taikhoom10•2h ago
Yeah I guess your right about that, build a quick MVP and validate from there. Makes sense.
PaulHoule•1h ago
Note there is a slice of B2C products that are sold like he is thinking. I wanted a subscription to Polypane, got a free trial and ultimately my administrative assistant punched in our P-card number to their web site. I had to fill out paperwork to satisfy one of New York’s largest private employers, but the burden was all on me —- though there would have been no free trial for a product that didn’t exist and the paperwork wouldn’t have been so simple if it didn’t.
kilian•1h ago
Hey, Polypane founder here hoping to get feedback and iterate ;)

Needing to fill in the paperwork for a saas is a PITA. Is there anything I could add to the site or elsewhere that would have made that easier for you?

PaulHoule•50m ago
My Uni has site licenses for many products such as Snagit 2025 and if I want a license for that the skids are greased. You did everything right from the viewpoint of an early adopter, in the future I guess your sales people could talk to our Central IT and negotiate something, if you send me an email I could try to find out how you would talk to.
