When founders post on LinkedIn for three weeks and then go quiet, the cause is rarely laziness. They run out of things to say. Week one is the obvious idea you'd been sitting on. Week two is a decent follow-up. By week three the well is dry, posting feels like homework, and the account goes quiet.
Content pillars are the fix. They're a small set of recurring themes you post about, chosen once, so that "what do I post this week" stops being a blank-page problem and becomes a question of which pillar to pull from.
Content pillars are an old idea, just under-explained for founders specifically, who have a different set of raw materials than a creator or a marketer does.
What a content pillar actually is
A pillar is a topic you have enough real material to post about more or less forever. The test is simple: could you talk about this for ten minutes without preparing? If yes, it's a candidate. If you'd have to research it, it's not a pillar, it's a one-off.
Three to four pillars is the right number. Two is too narrow and the account gets repetitive. Six is too many and none of them gets enough reps to stick in the audience's mind. Three or four gives you variety without dilution.
The pillars overlap with what you sell, but they aren't your sales pitch. People follow a founder for the thinking, the stories, and the occasional strong opinion. The product comes through sideways, in how you talk about the problem you work on.
Pillars that work for founders
These are starting points. Yours should come from your actual life, not a list.
The build. What you're shipping, what broke, the decision you made and why. Founders have an endless supply here because you make consequential calls every week. The honesty is what makes it work: "we shipped this and it flopped" outperforms "excited to announce" by a mile.
The lessons. Things you got wrong and what you learned. A founder who admits a hiring mistake or a pricing miss is more credible than one who only posts wins. This pillar builds trust faster than any other.
The opinions. Where you disagree with the consensus in your space. Pick the takes you'd defend in a room full of peers. Strong specific opinions are what get cited, shared, and remembered. Weak agreeable ones disappear.
The customers. What you're hearing from the people you sell to, anonymized. This pillar does double duty: it's interesting content and it's market research you're doing out loud. Patterns in customer conversations are some of the best raw material a founder has and almost nobody mines them.
The behind-the-numbers. The metrics, the experiments, the things that surprised you. A real number with a story around it is one of the most engaging things on LinkedIn, because it's specific in a place full of vague.
You don't need all five. Pick three or four that you actually have material for, and that you'd enjoy talking about. Enjoyment matters more than it sounds, because the pillars you dread will quietly kill the habit.
How to choose yours
Look backward, not forward. Open a notes app and write down the last ten things you found yourself explaining to someone, a teammate, an investor, a friend who asked what you do. The topics you naturally explain are your real pillars. They're proven by the fact that you already talk about them unprompted.
Group them into themes. You'll usually see three or four clusters emerge. Name them plainly. "Hiring at an early startup." "B2B pricing." "Building in a crowded market." The names are for you, not the audience.
Pressure-test each one with the ten-minute rule. If you can riff on it without prep, keep it. If you can't, it's a topic you're interested in but don't have lived material for yet, and it'll run dry by week three same as before.
The pillar trap
The mistake is treating pillars like a content calendar with assigned slots. Monday is build, Wednesday is opinions, Friday is customers. That turns posting back into a chore and the posts start to feel manufactured, because you're forcing a topic to fit a slot instead of posting the thing that's actually on your mind this week.
Use pillars as a menu, not a schedule. Each week, whatever happened, ask which pillar it belongs to and post that. Some weeks you'll have three build stories and nothing else. Fine. The pillars exist to make sure you never face a blank page, not to ration what you say.
Where the material comes from
Pillars solve the "what do I post about" problem. They don't solve the "I still have to sit down and write it" problem, which is the other half of why founders go quiet.
This is the part I think about most, because it's the part that's actually built into how Edgar works. The weekly conversation is organized around exactly these pillars: the build, the lessons, the opinions, the customers, the numbers. You talk through your week across those themes for 15 minutes, and the posts come back drafted in your voice, sorted into the pillars you care about. The pillars stop being an abstract framework and become the actual prompts in a conversation.
Pick your three or four. Then make talking about them a standing 15 minutes on your calendar, and the blank page stops being your problem.
