?Building a bet on your goals app — am I just validating with friends who’d say yes to anything? How do I get honest signal?

On an HN thread, commenter Edmar recommended a specific reading + outreach combo for fixing friend-bias in validation: “I highly recommend you the book “The Mom Test”. It’s a great read on user interviews for product validation.” His complementary cold-outreach approach: “Look for people who blogged or tweeted about topics related to your product. Not everybody will respond but people that take the time to share what they know have a tendency to help other people.” The pattern: The Mom Test (Rob Fitzpatrick) is the canonical playbook for asking validation questions that don’t lead respondents into politeness; combining it with cold outreach to writers who already publicly cared about your problem area yields a non-friend, non-random sample biased toward people who would act.

From an HN thread, commenter mchasse framed the common error: “I think that the general advice of “find something that bugs you and then fix it” is a particularly bad way of building a business because you run a very high risk of building something that nobody else wants. In general, “you” != “your customer”.” His alternative: “go out and find some group of people/companies and then ask them what problems are they currently facing that are not currently ideally solved (stressed out moms, small businesses, etc.).” Applied to a behavior app like CommitBet: don’t just test if friends like your solution — go find people currently failing at goal commitment (gym dropouts, finance-stake apps, journaling abandonners) and ask what they currently use and what’s broken about it. Then map your mechanic to that gap.

Another HN commenter (lionhead) described landing-page validation as the standard pre-product step: “Generally, the landing page is not an MVP, it’s just that: a landing page. It’s a cheap and quick way to get at least some market validation before you start working on your actual product. Depending on the product, it could be little more than a more elaborate form of customer interview (asking someone: would you pay for this? Does this sound like something you would use?).” For a behavior-bet app where the action gap is huge: ship a landing page describing “bet $5/day on your goal with a friend, lose if you skip” and instrument both signups AND payment-intent (clicks on a pay $X to commit CTA). High signups but zero payment-intent is hard validation that friends saying I’d use it isn’t enough.
