What matters more to a startup's success: the idea or the execution?

Paul Graham · published Mar 2005

What matters in a startup is the quality of the people, not the ideas.

Good people can fix bad ideas, but good ideas can't save bad people.

Founders matter far more than the initial idea; what should be evaluated is whether applicants are good at making things.

YC puts little weight on the idea and asks mainly out of politeness; the question they care about is what cool things you've made.

Scope: Y Combinator's selection practice

Picking good cofounders is the most consequential early startup decision, because cofounders are far harder to change than the idea and success is mostly a function of the founders.

You can change your idea easily but changing cofounders is hard, and startup success is almost always a function of its founders.

What distinguished the Airbnb founders was their earnestness and energy — they did nothing half-way — not the quality of their initial idea or traction.

At the interview YC didn't even like the idea and the company had no growth, yet the founders' energy made them impossible not to like; during the batch no one worked harder or absorbed advice faster.

Ideas stop being exclusive the moment you say them out loud, so an idea alone can be copied by a hundred better-funded or more passionate people; the founder is what persists

Scope: ideally he evaluates the multiple of founder quality times idea quality, not one alone

The most underrated element of entrepreneurship is pure execution — most founders are simply bad at running companies because they aren't intentional about time, decisions, hiring and what they say no to

Almost every startup's initial plan is broken, and the successful ones let customers redirect them.

If companies stuck to initial plans, Microsoft would sell programming languages and Apple printed circuit boards; their customers told them what the business should be.

Lacking a good initial idea is not really a problem, because most startups substantially change their idea anyway.

A startup's initial idea matters less than the founders' behavior, because ideas morph — nearly every big startup started out doing something else — and founders on the ground understanding their users is a very good sign.

Ideas can morph, so the signal to weigh is founders hunting down and understanding users.

It is a dangerous mistake to think successful startups embody a brilliant initial idea; promising ideas are often different in kind from the great ones they evolve into.

Early adopters you evolve the idea on have different needs from the rest of the market — the idea that becomes Facebook is a site for Harvard undergrads, not a subset of Facebook.

Paul Graham · published Aug 2007

Given smart founders and promising ideas, outcomes are determined by not giving up, since disaster before liquidity is near-certain.

The odds of getting from launch to liquidity without some kind of disaster are one in a thousand, so demoralization rather than the disaster is the real risk.

The only thing that varies across companies is the rate at which they reach an outcome, not whether they can reach it — a founder can brute-force almost anything, even taking a lemonade stand to $100M ARR

Some companies hit $100M revenue fast and some take very long, but persistence is what determines arrival; sometimes conditions favour you and sometimes they don't

Most businesses that fail do so because they don't give customers what they want; restaurants with genuinely good food prosper regardless of other flaws.

About a quarter of restaurants fail in the first year, yet you can't think of one with really good food that went out of business; great food overcomes expense, noise, dinginess and bad service.

When you have a good idea you are never the only one who has it, and you have far less time to act than you think

You don't need a brilliant idea to found a startup, because existing technology is often so bad that beating it doesn't take brilliance.

Startups make money by offering better technology than people have now, and what people have now is often terrible; Google's plan was simply to build a search site that didn't suck and that alone earns a billion dollars a year.
