A startup is a company built to grow fast on a new product; a small business is built to earn a steady profit from something proven, like a shop, an agency or a clinic. Steve Blank defines a startup as an organisation searching for a repeatable and scalable business model, and Paul Graham calls 5 to 7% growth a week a good rate inside Y Combinator. India's legal test is narrower: DPIIT counts a company as a startup for up to 10 years from incorporation if turnover stays under ₹200 crore and it works on innovation, while a micro enterprise on Udyam has investment up to ₹2.5 crore and turnover up to ₹10 crore. Pick by goal: growth funded by investors, or profit you keep.

Steve Blank's definition of a startup as an organisation formed to search for a repeatable and scalable business model, and why that makes it different from running a known business.

This is the essay that forces the honest question underneath your idea: are you building a growth company or a good small business, because they are different DNA and require different lives. Graham is blunt that a barbershop is not a startup no matter how new it is, and that clarity helps you choose on purpose instead of drifting. There is nothing wrong with either path, but you should pick the one you actually want before you spend years on it.

The official source for DPIIT recognition, the free registration that unlocks tax benefits, self-certification, and scheme eligibility for Indian startups. Straight from the government, not a middleman.

The government's only portal for registering a micro, small or medium enterprise. It states registration is free and lists the revised limits: a micro enterprise has investment up to ₹2.5 crore and turnover up to ₹10 crore, a small one up to ₹25 crore and ₹100 crore.

The government's own comparison, and it leads with the exact filter you need: if you are raising funding, the decision is made for you (Private Limited), and everything else is secondary. It covers all five Indian structures including OPC. Two parts are dated: its OPC section still says an OPC must convert past Rs 2 crore of revenue or Rs 50 lakh of capital, a rule removed in 2021, and its tax lines mention dividend distribution tax, which no longer exists.

The foundational essay behind YC's whole worldview. Graham argues a startup needs good people, something users want, and low spending, and he puts people first for a reason. It gives you the vocabulary to judge whether your founding team can actually build and ship, not just pitch.
