A real exchange from Planet 1 — Founder Fit.

Founder Fit
You say you want to fix morning routines. What personal experience made you care about this problem?
I've tried every alarm app out there. They all treat waking up as a sound problem, not a motivation problem.
Interesting — but using alarm apps doesn't mean you understand the market. What evidence do you have that others feel the same frustration?

MARVIN CODER 1
Roasts products, clones them live, and writes the guides your
CS degree forgot. Prepare yourself.
$ cat /srv/about.txt
From teardowns of overpriced SaaS to speedruns where we clone them in hours, plus engineering guides, deep dives, and the occasional trip into hyperspace where Marvin thinks out loud about things nobody asked. Everything is free. Everything is honest. He insists you won't enjoy it. Most people come back anyway.

"I kept building things nobody wanted. Roast Rocket is the honest friend I wish I'd had earlier."
— Built by a founder who learned the hard way
It asks the questions investors are too busy to ask — and friends are too polite to say out loud.
Read the full whyThe same questions founders ask us before they launch — answered straight.
Validation is a stress-test, not a vote. Don't ask “would you use this?” — measure whether the problem is real, painful, and someone is already trying to fix it. The cheapest version: five honest conversations with people in your target market. The faster version: stress-test your idea with Roast Rocket before you book those calls.
Up to 90–95% of new ventures fail — and it's rarely bad code or bad luck. They build something nobody wants. Roast Rocket maps every idea against the five things that actually decide it: founder fit, market reality, timing, business model, and moat. If even one of those is broken, the rest doesn't matter.

Good ideas survive contact with hard questions. Can you name the buyer? Will they pay today? Why hasn't a competitor done this already? Why now? If you flinch on any of those, your idea isn't bad — it's just untested. That's the gap Roast Rocket exists to close.
Idea validation comes first — you confirm the problem is real and the audience exists. MVP validation comes after — you confirm people will actually pay for the specific solution you built. Skip step one and your MVP is just an expensive opinion poll.
Persevere when the problem keeps testing real but your current solution misses. Pivot when the problem itself is weaker than you assumed. Walk away when neither holds up. Roast Rocket's per-planet feedback tells you which of the three you're looking at.
Yes. Five planets, fifteen questions, full PDF report — free, no signup, no card. We rate-limit per IP to keep costs sane; otherwise it’s open.
