Your One-Liner
6 min read
Every founder struggles with this. Even experienced ones. It seems like it should be easy... but writing a one-liner that actually works is harder than it looks. And it's always way easier to critique someone else's than to fix your own.
You should be telling everyone what you're doing. Constantly. You never know who is going to be an investor, a customer, or knows someone who is. But if you're like most founders, when that moment comes you'll say a bunch of stuff... industry jargon, buzzwords, something about being transformative or agentic or scalable. They'll nod. You'll finish. And then comes the question that destroys the pitch.
“But what do you actually do?”
You said stuff. You just didn't say what you do. For who. And why they should care.
This Isn't an Advertising Problem
Most founders approach their one-liner like a tagline. They want it to sound exciting. Premium. Big. So they reach for the language of transformation and category creation and platform thinking.
That's the wrong goal. You're not writing a brand campaign. You're trying to get a person to understand what your company does... clearly enough that they can decide if it's relevant to them, and if so, tell someone else about it later.
Your one-liner is not for sounding impressive. It's for being understood. Those are very different things.
Why Founders Default to Buzzwords
It's not laziness. It's actually the opposite. Founders know too much about what they're building. They live inside the problem. And the language of their problem space... the jargon, the frameworks, the industry terms... feels precise and accurate to them.
“Agentic workflow orchestration” means something specific if you spend your days in AI infrastructure. To everyone else it means nothing. The words that feel most accurate to you are often the words that communicate the least to everyone you actually need to reach.
There's also a fear underneath it. If you say something specific and concrete, you might sound small. Like you're not thinking big enough. So founders hide behind abstractions that sound appropriately ambitious but describe nothing.
Vague does not sound ambitious. It sounds confused. Specific sounds confident... because you actually know what you're building and for whom.
What It Actually Needs to Do
Three things. In this order.
- What you do. Not your vision. Not your category. What you literally do for a person.
- Who it's for. Specific enough that I can tell if that's me, or someone I know.
- Why they should care. Something that makes a relevant person think: I need to know more.
That's it. Everything else... the technology, the moat, the vision, the market size... comes later. Only after the one-liner works does anyone want to hear those things.
Build It Like You Build Your MVP
Start with the literal description of what happens when someone uses your product. Walk through it like you're explaining it to someone who has never heard of the problem.
- Who is the person?
- What do they have before they use you?
- What do they have after?
- Why does that change matter to them?
Strip out every word that requires prior knowledge of your industry. Write it for a smart person who has never once thought about your problem space.
[What you do] + [for who] + [so they can / without having to]
You won't always use every piece explicitly, but you should be able to answer all three before you cut it down.
Bad vs. Good
These are the kinds of one-liners founders actually write. And the version that works.
“We're building the future of work through intelligent task automation.”
Who is this for? What does it do? What does “intelligent task automation” mean in practice? This says nothing except that you like the future.
“We help operations teams at logistics companies eliminate the manual data entry that happens between their software systems.”
Now I know who it's for, what problem it solves, and what life looks like without it.
“An agentic OS for startups.”
Means something to a very specific type of person. Nothing to anyone else. Including most founders.
“Pre helps startup founders focus on their highest-impact work every week with an AI advisor that knows their startup.”
Founders don't want to waste time or money. They know the pain of losing focus or missing the opportunity that was right in front of them. The “AI advisor that knows their startup” adds just enough intrigue without requiring translation.
The Hours-Later Test
At the end of a day, several hours after your pitch or conversation... can the person you talked to explain what you do to their spouse? To a friend? To someone who doesn't care about tech at all?
If they can't repeat it back in a sentence, it didn't stick. And if it doesn't stick, it doesn't spread.
Word of mouth is the most powerful growth channel at the early stage. Your one-liner is the unit of word of mouth. If it can't travel, neither can you.
It's Not Fixed. It's Work.
Most founders write a one-liner once, get some polite feedback, and stop working on it. That's the same mistake as building an MVP and never iterating.
Your one-liner should change as you learn more about your customer. As you talk to more people and see which words make eyes light up and which ones create blank stares. As you figure out who your actual customer is versus who you thought it would be.
After every conversation, ask yourself: did that land? Did they get it immediately, or did they ask a clarifying question that told you something was missing? Use that as feedback. Iterate the same way you iterate the product.
Keep a running note with every version you try and how it landed. A single word change can make a one-liner go from confusing to obvious. Pay attention to that.
Every week, take another pass at it. You'll have learned something new about your customer, your product, or how your existing one-liner is landing. Use it.
The Second Line
People are busy and distracted. They need something efficient and informative... not a two-paragraph explanation of what you do. Give them one sentence. If it's good enough, they'll ask for more.
“Oh interesting, how does that work?”... that's the signal. It means the one-liner did its job. You opened the door. Now you get one more sentence.
“Pre helps startup founders focus on their highest-impact work every week.”
If that hooks interest... “We help them set a 10-week sprint goal, give them an AI advisor connected to their startup data, and automatically send progress reports to their investors every week.”
The second line earns the demo. The demo earns the close. Same pattern as everything else in early-stage building: focus on the next thing that unlocks the next thing. The one-liner comes first. Nothing else happens until it works.
Strip out the jargon. Strip out the vision. Say what you do, who it's for, and why that matters. Say it in plain language to someone who has never thought about your industry. Watch their face. Adjust. Repeat.
Pre keeps you focused on the work that matters most. Set a 10-week sprint around your most important goal, get weekly AI coaching, and stay accountable with real pressure from people who care about your success.
