Most ecommerce founders we onboard have the same problem, and it isn't writing. It's that nobody can tell you what they actually believe.
They post tips. They post wins. They post the occasional industry reaction. Every post is individually fine. But scroll their profile top to bottom and you can't extract a single position they'd defend in a room full of people who disagree. The content has no spine.
That missing spine has a name. We call it the founder thesis — the one contrarian belief about your market that everything else hangs off. Get it right and you stop writing posts. You start making an argument, one post at a time. This is the single highest-leverage piece of founder branding work we do, and it happens before we write a word.
What a founder thesis actually is
A founder thesis is a one-sentence claim about your market that a smart, informed competitor could reasonably disagree with.
That last part is the whole game. If everyone in your category already agrees with it, it's not a thesis — it's a platitude. "Good creative matters" is a platitude. "Most Amazon brands are spending on ads to paper over a conversion problem they've never measured" is a thesis. One makes people nod and scroll. The other makes a chunk of your audience think wait, is that me?
Here's how to pressure-test a candidate. State the opposite out loud. If the opposite sounds obviously stupid, you have a platitude. "Bad creative matters" is stupid — so "good creative matters" is dead on arrival. But "you should fix your ads before your conversion rate" is a position a lot of operators actually hold. Which means the reverse is a real thesis with a real enemy.
A thesis needs an enemy. Not a person — a default belief, a lazy consensus, a way of doing things that most of your market accepts without thinking. Your content exists to attack that default. That tension is what makes people stop, argue in the comments, and remember who you are.
Why founders resist narrowing to one
When we tell a founder their entire presence should orbit one belief, the pushback is immediate: won't that box me in? I do more than one thing.
You do. But your audience can only hold one thing about you in their head. Ask yourself who you think of for "Amazon PPC." You probably named one person in under two seconds. Now name the second and third. Slower, right? And by the fourth you're guessing. The market sorts people into one slot each. You don't get to pick whether that's true — you only get to pick whether you chose the slot or whether the algorithm assigned you a vague one.
The founders who refuse to narrow don't end up known for many things. They end up known for nothing, because a profile that argues five beliefs argues none of them with enough repetition to stick. Repetition is what builds authority, and you can't repeat five things.
Narrowing your thesis doesn't shrink your business. We've watched founders pick one pointed belief, hammer it for ninety days, and have inbound show up asking about services that belief never mentioned — because the belief proved they think clearly, and clear thinking is what people actually buy.
How to find yours
You don't invent a thesis. You excavate it. It's already in how you operate — you've just never said it out loud because to you it's obvious. Three places we dig:
The thing that makes you roll your eyes. What advice in your category do you watch get repeated and quietly think is wrong, or right for the wrong reasons? That eye-roll is a thesis trying to surface. The conventional wisdom you've privately rejected is exactly the consensus your content should attack.
The decision you make differently. Where does your actual operating behavior diverge from what your peers do? If you kill SKUs everyone else would keep, or refuse a tactic the whole category swears by, there's a belief underneath that. Name the belief.
The sentence you keep saying on calls. Most founders have a line they repeat to every prospect — the thing they always end up explaining because the market keeps getting it backwards. That line, said enough times to enough confused people, is usually the thesis in its rawest form. It's already battle-tested. You just never put it on LinkedIn.
When we run a thesis session, we're not brainstorming. We're listening for the moment the founder gets a little heated, says "honestly, most people in this space just—" and then makes a claim. That claim is the asset. Everything before it was warm-up.
What changes once you have one
A real thesis fixes the two things founders struggle with most.
It kills the blank page. "What do I post today" becomes "what's one more piece of evidence for the thing I believe." A case study, a number, a screenshot, a contrarian reaction to the news — they're all the same post now, the argument from a new angle. You go from inventing topics to drawing from a well that doesn't run dry, because a single strong belief generates infinite supporting posts.
It makes you decline-able, which makes you choose-able. A thesis with a real enemy will repel part of your audience. Founders flinch at this. Don't. The people who bounce off your position were never going to buy — they'd have wasted a sales call instead. The people who lean in because you said the unpopular thing are pre-sold on how you think. Polarization isn't a side effect of a good thesis. It's the point. A profile that offends no one converts no one.
A quick gut check
Go to your own profile. Read your last ten posts as if you were a stranger. Then try to finish this sentence in one line: "This person believes that ___."
If you can't — if the best you can do is "this person knows about ecommerce" — you don't have a founder brand yet. You have a tips account. The fix isn't more posts. It's one belief, stated plainly, argued relentlessly, until the market files you under it.
We do this excavation with every founder before we touch a single post, because writing in someone's voice is easy once you know what that voice is for. If you've been posting for months and still can't say what you stand for in one sentence, that's the gap worth closing first — let's talk.
So here's the question worth sitting with: if a stranger read your last ten posts, what one belief would they say you're arguing — and is it the one you'd actually want them to file you under?
