A tagline is not the place to prove you're creative. It's the place to prove you understand the problem better than anyone else in your category. The best startup taglines aren't the most clever ones on a shelf of competitors — they're the plainest ones that still manage to say something specific.
The Same Rule as Everything Else: Problem, Then Solution
Donald Miller's StoryBrand work makes the case that a good tagline is really just a compressed version of the customer's problem and the promise of a fix, and I think that's right as a starting principle. Where I'd add my own spin: a tagline doesn't need to state both halves outright. Sometimes it just needs to point at the problem sharply enough that the solution is implied.
- Too clever: "Unlock your potential."
- Too vague: "The future of work."
- Plain and specific: "Invoicing that gets you paid in days, not months."
- Plain and specific: "Stop losing candidates to slow hiring."
Notice the last two aren't trying to be memorable through wordplay. They're memorable because they name something the reader has personally felt.
Don't Get Fancy, Don't Get Technical, Don't Get Egotistical
Three traps I see founders fall into, in order of how often I see them:
Fancy. Metaphors, puns, and wordplay that require the reader to pause and decode them. If someone has to think for two seconds to understand your tagline, you've spent your only two seconds of their attention on decoding instead of understanding.
Technical. Taglines that describe the architecture instead of the outcome. "AI-powered predictive analytics for supply chain optimization" is a technical description wearing a tagline's clothes. Nobody outside your engineering team talks like that, and nobody outside your engineering team is going to remember it.
Egotistical. Taglines about the company's ambition instead of the customer's problem. "Building the future of finance" tells me what you think of yourselves. It tells me nothing about what changes in my life if I use your product.
A Quick Way to Test a Draft
Write your tagline, then ask: could this run underneath a picture of a stressed-out person doing the thing your product fixes, and would it make sense? "Stop losing candidates to slow hiring" works under a picture of a recruiter staring at an inbox. "Unlock your potential" works under literally any stock photo of a sunrise. That's the tell.
If you're still stuck, go back to your customer interviews. The best taglines are usually a slightly trimmed version of a sentence a real customer already said to you, unprompted.
Give Yourself Permission to Be Boring on Purpose
The taglines that feel underwhelming to write are often the ones that work best, because they're not competing with your product for attention. A tagline's job is to get out of the way fast, hand the reader a clear idea, and let the rest of the page do the convincing.
Frequently Asked Questions
How long should a startup tagline be?
Under ten words, ideally under seven. If it takes longer than a breath to say out loud, it's closer to a sentence than a tagline, and it'll get cut for space eventually anyway — might as well cut it now.
Should a tagline change as the company grows?
Often, yes. A tagline written for an early, narrow product sometimes stops fitting once you've expanded. Revisit it whenever your actual customer base has shifted meaningfully from who it was when you wrote the original.
Can a tagline be funny?
Sometimes, if the humor doesn't come at the expense of clarity, and if it fits your brand voice. The test is the same either way: would someone unfamiliar with your product still understand roughly what you do after reading it once?
Do I need a professional copywriter to write a good tagline?
Not necessarily — the raw material usually comes from your own customer conversations, not from a copywriter's imagination. A second set of eyes helps you cut the fluff, but you're the one who has to bring the specific, real language to start from.
