I’ve been going down a rabbit hole lately analyzing where founders typically get stuck when validating new ideas, and there seems to be a massive graveyard at the "Market Reality" stage.

It feels like a lot of people can easily validate that a problem exists, but they completely fail when trying to prove that people will actually pull out their credit cards to solve it (the classic "Vitamin vs. Painkiller" dilemma, or failing The Mom Test).

For those of you who have mentored early-stage founders, been through accelerators, or just learned the hard way after a failed launch: What is the biggest blind spot you see when founders assess their own market?

• Is it wildly overestimating their TAM and saying "our market is literally everyone"?
• Is it building a solution for a problem that isn't actually painful enough to switch from the status quo?
• Is it completely ignoring the unsexy reality of distribution and Customer Acquisition Cost (CAC)?
• Or is it something else entirely?

I’d love to hear some war stories or harsh truths you had to learn about market validation. What’s a "market reality" check you wish someone had given you before you wrote a single line of code?

so i made this thing roastrocket — ai roasts your startup idea across 5 dimensions (founder fit, market, timing, business model, moat) and spits out a brutal verdict at the end

problem: it's one-shot. you get your verdict, you leave. no reason to come back

been chewing on flipping the whole flow:

daily scenario drops at 9am, same one for everyone. like "comapny abc wants a new venture in home energy. €5M, 18 months. go"

you co-create the venture with ai (guided though, not just open chat — pick the wedge, define customer, draft the model)

submit your final answer

marvin (depressed robot judge, hitchhiker's guide reference) roasts it across the 5 planets

public leaderboard for that scenario, share card, streaks etc

so less "validate my real idea" and more "train your founder brain". also opens it beyond people who already have an idea — students, PMs, intrapreneurs, anyone who just likes thinking about this stuff

few things i can't decide:

would you actually open this daily? what keeps you coming back to wordle/connections/whatever and what would kill it for something like this

co-creation step — guided wizard (fill 5 blanks) or open chat with ai? wizard is easier to score and compare, chat feels more like a game maybe

scenarios — corporate missions (siemens, bosch type), constraint mode (€5k solo 12 months), or autopsies (pivot moviepass)? which would you actually click first

anyone already doing this? feels like a gap but i probably just haven't found it yet

roast away, that's literally the product
