How to validate a startup (it's not the same as a business)

People use “startup” and “business” interchangeably, but they're different animals — and validating them is different too. A local bakery is a great business; it's not a startup. A startup is a temporary organisation built to search for a repeatable, scalable model. That word — scalable — changes what you have to prove.

A startup must validate three things, not one

1. The problem and product — do people want this enough to pay or switch? (Same as any business.)
2. The market size — is the reachable market big enough that scaling is even possible?
3. The growth engine — is there a channel where acquiring a customer costs less than they're worth, repeatably?

A business can succeed by being good at one thing in one place. A startup has to show that success can compound — that the second hundred customers are cheaper to win than the first, and the market is deep enough to keep going. Skip the market-size and growth questions and you can validate a “business” that simply can't become a startup.

Investors don't fund problems worth solving. They fund problems worth solving at scale.

Validate the idea, then size the ambition

The IdeasBuenas path starts with a free analysis that checks whether the problem and product are real — the foundation both businesses and startups share. From there, the market-sizing step helps you judge whether the upside is startup-scale or business-scale, so you set the right expectations (and pursue the right kind of funding) from day one. Either way, you start from evidence, not ambition.

Whether you're building a startup or a business, the first question is the same: is the idea real? Find out for free.
