Calibrated 1-9 viability scoring for startup ideas. Most are a 4-6. Fewer than 10% score 8+. There is no 10. Your favorite idea is probably a 5.

A good idea solves a real problem. A viable idea solves a real problem that people will pay for before you're broke. Most founders skip the second part and call it optimism. #siftid #bootstrapped #startupideas #buildinpublic

Novel is what you notice. Valuable is what you pay for. Most founders spend all their energy on the first one and wonder why users won't do the second. #siftid #founders #indiehackers #bootstrapped

You solved a real problem. For yourself. That's a 5 until you find someone else who has it badly enough to pay. The gap between "this annoyed me" and "this costs them money" is wider than most founders think. #siftid #bootstrapped #startupideas #solofounder

Most founders can describe their product in thirty seconds. Ask them how a stranger actually finds it and they go silent. That gap is your real problem, not the product itself. #siftid #saas #bootstrapped #indiehackers

Ideas that require you to change how people think before they'll buy are trapped at a 5. They're not bad. They're just expensive to scale. The market isn't waiting for your education campaign. #siftid #solofounder #saas #founders

Most pitch decks say "TAM is 50 billion." What they mean is "I Googled an industry." The real question is how many of those dollars will flow to *you* before someone bigger notices. That number is usually smaller. #siftid #founders #startupideas #bootstrapped

If nobody's willing to pay until you've built the thing, that's not a validation problem. That's a signal the problem isn't painful enough to pay for solving. #siftid #founders #indiehackers #buildinpublic

Most founders score their timing as neutral. It's almost never neutral. Either the market just got ready for you, or you're five years early. The difference between a 6 and a 4. #siftid #buildinpublic #indiehackers #founders

Building in public works great if your idea is interesting enough to hold attention without momentum. Most aren't. You end up documenting a slow death for an audience of other founders pretending to be interested. #siftid #startupideas #solofounder #indiehackers

When choosing what to build first, ask: whose day gets measurably worse if this feature doesn't exist. Not who wants it. Who actually hurts. Most feature roadmaps are built on the opposite: who asked loudest. #siftid #saas #indiehackers #buildinpublic

Shipping a bad idea fast just means you waste time efficiently. The real question isn't "did you launch" but "did anyone care enough to pay." Most founders know this and ship anyway. That's the actual problem. #siftid #startupideas #bootstrapped #saas

"Uber for X" assumes the hard part was logistics. It wasn't. It was network effects, unit economics, and regulatory capture. You're building the easy part second. That's a 4. #siftid #founders #bootstrapped #buildinpublic

Talking to five potential customers is not validation. It's a conversation. Validation is when they've already paid or irreversibly changed behavior. Everything else is just hope with better receipts. #siftid #bootstrapped #indiehackers #founders

Most B2B founders say "we're going after X industry" when they mean "we're going after the one job title that actually has budget and pain." The wedge is three job titles narrower than you think. Start there. #siftid #solofounder #startupideas #indiehackers

An AI wrapper with a 2-week setup time is not defensible. Neither is one that saves you 10 minutes a week. The question isn't "does this use AI." It's "would a hungry competitor rebuild this in a month." #siftid #solofounder #buildinpublic #founders

An 8+ idea solves a problem people are already paying to solve, but does it 10x cheaper or faster. Not cheaper than free. Not faster than never. Cheaper or faster than the status quo they're actually using right now. #siftid #saas #indiehackers #bootstrapped

Novel is not a feature. If your idea's main selling point is that nobody's done it before, you have a 4. Valuable means someone will pay to have their problem solved today. Which one are you actually building. #siftid #indiehackers #founders #bootstrapped
10
If your idea requires users to change behavior before they'll pay you, it's probably a 5. What existing habit are you hijacking instead. #siftid #solofounder #saas #bootstrapped

Ambition isn't wanting to change the world. It's wanting to change something specific badly enough to spend two years on it. Most ideas fail because the founder would rather have won than win. #siftid #solofounder #startupideas #buildinpublic

Your favorite idea is usually your favorite because it's yours, not because it's viable. Kill it anyway. The good ones survive the second pitch. #siftid #startupideas #saas #solofounder
