Market size & timing

Is it big enough, and why now?

How big does my market need to be for this to be a real business? It depends on your ambition: a bootstrapped indie business can thrive in a market worth a few million, but a venture-backed one needs a market that... Intermediate 19 resources → What are TAM, SAM, and SOM and how do I actually calculate them? TAM is everyone who could ever use your category, SAM is the slice your product and geography can actually serve, and SOM is the realistic chunk yo... Intermediate 18 resources → Why does 'why now?' matter so much for a startup idea? Most great startups ride a change that just made something newly possible or newly cheap: a new technology, regulation, behaviour, or cost curve. I... Intermediate 17 resources → My market is small right now but growing fast. Is that a problem? A small, fast-growing market often beats a big, flat one, because you can ride the growth instead of stealing share in a knife fight. Investors and... Intermediate 16 resources → How do I size a market for India specifically when data is messy? Ignore the '1.4 billion people' headline; the real spendable market in India is a fraction of that. Use frameworks like Blume's India1/India2/India... Advanced 19 resources → Should I worry that my market is already crowded with competitors? A crowded market is proof that people will pay, which is a good sign, not a red flag. What kills you is entering a crowded market with no sharp wed... Intermediate 18 resources → How do I estimate a market size when the product I'm building doesn't have a category yet? When there's no clean market to point at, build the number from the behavior you're replacing, not from an analyst report that doesn't exist yet. C... Advanced 18 resources → Investors keep asking for a top-down TAM slide, but I built my number bottoms-up. Which do I show? Show both, but let the bottoms-up number lead and treat the top-down as context. Bottoms-up (customers times price times frequency) proves you actu... Intermediate 19 resources → How do I tell whether a market is genuinely emerging or just a fad that will fade in a year? Look for a durable structural shift underneath the excitement: a cost curve that dropped, a regulation that changed, a new default behavior that pe... Advanced 19 resources → My market is huge on paper but almost nobody is actually paying for solutions today. Good sign or bad? A big market with no spending usually means one of two things: you've found a real gap others missed, or there's a reason nobody pays that you have... Advanced 19 resources → How do I size a market I want to sell to businesses outside the big Indian startup hubs? Public data thins out fast once you leave the metros, so build the number from the ground: count the actual businesses (GST registrations, industry... Intermediate 19 resources → Is it smarter to enter a market while it's still forming, or wait until demand is obvious and proven? Entering early buys you a shot at owning the category, but you pay for it by spending years educating customers who aren't ready, and early is ofte... Intermediate 18 resources → How much of the market do I realistically need to capture for this to be a real business? Flip the question: instead of guessing a market share percentage, work backward from the revenue you need to be a healthy business and divide by a ... Beginner 20 resources → How do I know if the timing tailwind I'm counting on (a new regulation, a new tech) is real or wishful thinking? Pressure-test the tailwind by asking what specifically has already happened versus what you're hoping will happen. A regulation that's passed and e... Advanced 19 resources → My total market looks small, but each customer is worth a lot. Can a low-count, high-value market still work? Yes, and it's often a better business than a huge market of tiny accounts, because a few hundred customers each paying serious money can build a re... Intermediate 19 resources → Everyone says my market is too niche to be venture-scale. When are they right, and when are they wrong? They're right when the niche has a hard ceiling and no believable path to a bigger adjacent market: you win everyone and you're still small. They'r... Advanced 19 resources → How do I research market size and timing when I can only spend a weekend and have no budget for reports? Skip the paid reports entirely; you can get a defensible first estimate for free in a weekend. Count supply-side proxies (how many businesses, how ... Beginner 18 resources → Two of us disagree on how big the opportunity is. How do we resolve a market-size argument between cofounders?
