Why Does Your Company Exist?

When Core Purpose is clear, it acts as a filter for every decision the business makes. Hiring, strategy, what to say no to, where to invest, what to stop doing. When it’s vague, or borrowed from a competitor, or sitting in a slide nobody has opened since the last offsite, none of that happens. Decisions get made for reasonable but disconnected reasons. The business drifts without anyone noticing because there’s no fixed point to drift from.

Most companies have a mission statement. Most of their teams can’t say it without looking it up. That’s not a memory problem. It’s a relevance problem. The statement was never used to make a real decision, so nobody bothered to remember it.

Core Purpose is different. It answers the same question — why does this organization exist — but it earns its keep by being useful every day.

I wrote previously about defining your Owner’s Outcome — what you want the business to deliver to you personally, by when, measured by what. That’s the founder’s personal anchor. Core Purpose is the organizational anchor. One is about what the business does for you. The other is about why the business exists for the people it serves. Both need to be explicit. Both need to be known. And Core Purpose is the one the whole team aligns to.

This article explains why Core Purpose and BHAG (Big Hairy Audacious Goal, Jim Collins’s term for a company’s 10-to-30-year goal) matter, how the discovery process works, and where to find the prompt that will guide you through it.

Where it comes from

Core Purpose originates with Jim Collins and Jerry Porras in Built to Last. Collins defines it as half of a company’s Core Ideology, the part that should never change. The other half is Core Values. Together they form the foundation everything else is built on.

Collins’s tests for a good Core Purpose tell you what it’s supposed to do. It should be personally inspiring to the people in the organization. It should be as valid 100 years from now as it is today. It should help you think expansively about what to pursue and what to eliminate. It should be authentic to what the organization actually is. And the team should greet it with enthusiasm, not cynicism.

That last one is the test most companies fail. If you have to sell the team on the Core Purpose, it’s the wrong one. The right one is already true. You just haven’t named it yet.

BHAG — Big Hairy Audacious Goal — comes from the same lineage. Collins introduced it in Built to Last and developed it further in Good to Great through the Hedgehog Concept. It’s a 10-to-30-year goal. No numbers. Something the team can believe in, align to, and drive toward with every decision. The BHAG sits at the intersection of three things: why you exist (Core Purpose), what you can be best at (core business), and how you make money (Profit/X). You need all three to find it, and Core Purpose is the first one.

Shannon Susko integrates both into the Metronomics operating system as the foundation of the Cultural System. She puts it plainly: team culture trumps strategy. If the team doesn’t understand and buy into the company’s reason for existing, strategic planning will not right the ship.

Why this matters for founders

I saw this in my own company. For most of the first 25 years we didn’t have a Core Purpose that anyone could articulate. We had a vague sense of why we existed, and that vague sense was good enough when the business was small and the founder was in every conversation. But as the company grew, decisions got made by people who didn’t have the founder’s instinct. They had nothing to anchor to. So they made reasonable decisions that went in slightly different directions, and over time those small divergences added up to inconsistency. Not because the people were wrong, but because they had no shared filter for what right looked like.

A BHAG without a Core Purpose underneath it has the same problem. It might excite people briefly, but it won’t sustain them. When things get hard, when the market shifts, when priorities compete, the team needs to know not just where they’re going but why they’re going there. Core Purpose provides the why. The BHAG provides the where. Together they create a direction the team can hold onto when everything else is changing.

Most founders never start because they wait for the perfect answer. They wordsmith. They debate. They send it back for another round of input. And while they’re perfecting the statement, the team is making decisions without it. Good enough and known beats perfect and sitting in a draft.

The problem with the standard approach

The standard approach is to sit the leadership team in a room, hand out sticky notes, and ask everyone to write down why the company exists. You share, group, discuss, and agree.

That process is fine for refinement. It’s poor for discovery. Direct questions produce aspirational answers. “Why does this company exist?” triggers the part of your brain that wants to sound impressive, not the part that actually knows the truth. You end up with something that could describe any company in your industry.

The same thing happens with BHAG. Ask a room “where should this company be in 20 years” and you’ll get a mix of financial targets, market positions, and motivational language that nobody believes and nobody can use.

Real Core Purpose doesn’t live in what you say when asked directly. It lives in why you started the company, what you’d miss if it disappeared, what your clients would lose without you, and what’s true about a founder after working with you that wasn’t true before. The only way to find it is to go looking in those places.

How the process works

The full prompt is available on my Tools page. Here’s the logic behind it.

Phase 1: Core Purpose. The interview starts with origin. Why did you start this company? Not why does the company exist — why did you start it. Founders have a personal answer to this that nobody else in the building has. That answer is the raw material.

From there it pushes past the financial answer. The first response is almost always about money, opportunity, or freedom. Those are results. The interview keeps going. What does the money make possible? What would be lost if it made money but stopped doing the thing that makes it worth running? What would you miss if you sold and couldn’t start another one?

It tests whether the reason evolved. The reason you started it and the reason it exists now may not be the same. Both are true. The Core Purpose is the one the team would recognize today.

It surfaces the pattern across your answers, then separates what the work gives you personally from what the company does for the people it serves. The founder’s personal motivation matters, but it lives in the Owner’s Outcome, not the Core Purpose.

Once the thread is clear, you say it in one sentence. Then the interview tests it. Six criteria. Durability — would it hold if the products, markets, and strategy all changed? Authenticity — would the team nod or roll their eyes? Utility — does it help you say no? Specificity — does it describe what your company actually does, or is it so broad it could describe any company in any industry? Simplicity — could every person in the company say it from memory? Integrity — do you genuinely believe it?

If any test fails, you go back. If they all pass, Core Purpose is locked and the interview moves to BHAG.

Phase 2: BHAG. The interview defines the remaining two circles. What can this company be best in the world at? Not what you want to be best at — Collins is specific about this — but what you can be best at given genuine capability. Then how the company makes money: the one unit that drives the economics, what Shannon Susko calls Profit/X.

With all three circles defined, the interview asks you to write the BHAG. One sentence. No numbers. Then it tests for tension. If your business model is deliberately small but the BHAG implies unlimited scale, the interview names it. Both can be true — a small practice that proves the work, with writing or tools extending the reach — but the founder has to resolve the tension, not ignore it.

Three tests close it out. Would the team feel excited or skeptical? Does achieving it require living the Core Purpose every day? Would you still be working toward this in 20 years? If all three pass, the BHAG is locked.

Multiple founders

If there is more than one founder, each completes the interview independently on their own device. Do not share answers until both are done.

After both finish, a separate synthesis conversation compares the outputs side by side. Where founders arrived at the same answer independently, that’s confirmation. Where they didn’t, that’s a misalignment that needs to be resolved before anything else will hold.

Two founders with different answers to “why does this company exist” will fight about everything downstream without understanding why. This exercise surfaces it. The prompt includes instructions for the merge.

Leadership team validation

Whether there is one founder or more than one, the final step is the same. Have each member of the leadership team independently answer two questions before seeing the founder’s answers. Why does this company exist? Where is this company going over the next 10 to 30 years?

The agreements are confirmation. The disagreements are where the real alignment work happens. Resolve them before building anything on top of this foundation.

What to watch out for

The process is only as good as your honesty. If you give the AI surface-level answers, you’ll get a surface-level Core Purpose. The interview is designed to push, but you have to be willing to go there.

Founders often confuse what the work gives them personally with why the company exists for its customers. Both are real. The interview separates them, but the pull toward the personal is strong. If your Core Purpose sounds like it’s about you rather than about the people you serve, it probably is.

BHAG is where ambition can contaminate discovery. The interview asks what the company can be best at, not what you’d like it to become. If you jump to the goal before honestly assessing the capability, the BHAG will be aspirational rather than achievable. The Hedgehog Concept is about focus, not fantasy.

Finally, discovering Core Purpose and BHAG is the first step. Keeping them alive is the ongoing work. Quick confirmation at every quarterly meeting. Once a year, a deeper check: have each leader individually answer three questions from Simon Sinek’s Golden Circle framework. What does the company do? How does it do it? Why does it do it? The first two are easy. The third is where drift shows up. If the team’s answer to “why” no longer matches the Core Purpose on the wall, that’s not a failure. That’s a signal the foundation needs attention. If Core Purpose and BHAG are defined once and never revisited, they become exactly what you were trying to avoid: another statement nobody remembers.

About the prompt

The prompt is free to use and a work in progress. If you find problems, if a question doesn’t land right, if the output misses something, I would like to hear about it. And if you improve on it, I would appreciate it if you shared what you changed and why. You can reach me at [email protected].

Core Purpose originates with Jim Collins and Jerry Porras in Built to Last. BHAG and the Hedgehog Concept come from Collins’s Good to Great. Shannon Susko integrates both into the Metronomics operating system. Simon Sinek’s Golden Circle is used as a validation tool. The underlying frameworks are theirs. I have applied them to a structured discovery interview. If these ideas resonate with you, read their work directly.
