Ideas & Opportunity

How do I evaluate whether an idea is big enough to be worth years of my life?

A starting point

Ask two separate questions: is the pain real and frequent, and can it grow into something large. A painkiller for a small but bleeding market is a fine start, because you can expand once you own it. Be honest that many good businesses are not venture-scale, and decide up front whether you want a solid company or a rocket, because the two demand different ideas.

Why we picked it Kevin Hale is a YC partner and cofounder of Wufoo, so this is both the investor lens (what makes a bet worth backing) and the operator lens (someone who built and sold a company). His core move is treating an idea as a hypothesis about why the company will grow fast, which is exactly the question to ask before you sign up for years on it. Use it as a starting point to pressure test your own idea, not as a verdict.

How to Evaluate Startup Ideas
  • An idea is a hypothesis for why the company will grow quickly, made of a problem, a solution, and an insight, so be honest about whether the growth story holds.
  • You need an unfair advantage, a concrete reason you will win and reach people faster than everyone else, before the years of commitment make sense.
  • Evaluate your own idea the way an investor would, since that is the same lens that tells you whether it is big enough to be worth your life.

Why we picked it Most market sizing advice online is generic TAM SAM SOM filler. This one is written by an investor, backed by a survey of 30 VCs, and it is honest about the thing that matters: a big number pulled from an industry report proves nothing. It walks you through building the number bottom up (customers times what they pay you per year), which forces you to confront whether real people will actually pay, and that is the honest test of whether an idea can grow past a niche.

Market Sizing Guide

From Pear VC by Ian Taylor ~15 min read

  • Size the market bottom up (count of real customers times annual revenue per customer), not by claiming a percent of some giant top down figure.
  • TAM, SAM, and SOM are used loosely across the industry, so state your assumptions plainly instead of hiding behind the acronyms.
  • Project the market out five or more years and include how you would actually reach and acquire customers, since a market you cannot serve is not your market.

Why we picked it 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.

Startup = Growth

From Paul Graham by Paul Graham ~20 min read

  • A startup is defined by fast growth, not by being new or funded, so a business that cannot grow fast is a different (and often fine) choice, just not a startup.
  • Growth needs two things at once: something many people want, and a way to reach them at scale, if either is missing the idea caps out as a niche.
  • Deciding whether your idea can grow beyond a niche is really deciding what kind of company, and what kind of years, you are signing up for.
