Elevator pitch example: your startup explained in one sentence

At a wedding in Lecce, a cousin asks what your startup does. You begin with the market, drift into the technology, mention a pilot, and around the fortieth second their eyes wander off to the buffet. It will happen to you, if it hasn’t yet. The cure is one sentence you could say half asleep, and this guide builds it with you, piece by piece, up to a full elevator pitch example you can adapt.

By the end you’ll have a four-part formula for your one-liner (who, problem, what you do, proof), a 30-second version for when someone actually wants to hear more, and a free way to test both on ten people before any investor sees them.

What is a one-liner, and how is it different from an elevator pitch?

A one-liner is the sentence that answers “so, what do you do?”. You’ll use it everywhere: as the opening of your pitch deck (the short slide presentation investors read before they meet you), in the first line of an email, in application forms, under your name on LinkedIn.

An elevator pitch is longer. It’s what you can say while a lift climbs a few floors, roughly 30 seconds: the one-liner, the problem as your customer feels it, one fact that proves it’s real, and what you want from the person in front of you. If the sentence is weak, the extra seconds won’t rescue it.

Investors read that sentence closely. Sequoia’s guide to writing a business plan, which Airbnb’s founders came across before making their early deck, opens with it: “Start here: define your company in a single declarative sentence. This is harder than it looks.” And when DocSend studied how investors read pitch decks in 2022, time spent on the company purpose section had shot up. Investors were using it as “a kind of gatekeeper”.

The one-liner formula: who, problem, what you do, proof

Four pieces, in this order. They won’t always fit in one breath, so the proof often becomes a second, shorter sentence.

1. Who. One customer group you can picture: “independent bakeries”, not “the food sector”. If you sell to companies, say which ones and roughly how big.
2. Problem. The pain in their words. A baker doesn’t talk about supply chain inefficiency. She says she bins unsold bread every evening.
3. What you do. The product in plain words, built around a verb: tells, books, pays, finds, checks.
4. Proof. One fact that shows people want it, what investors call traction: customers, revenue, a pilot, a waiting list, a growth rate.

The template is: [Name] helps [who] [solve what] by [doing what]. [One fact.] Fill it in badly first. Everyone does.

Y Combinator’s partners have pushed the same discipline for years. In his guide to pitching, Michael Seibel asks founders to explain what they do “in the simplest language possible” and to cut “jargon, acronyms, marketing speak, and any ambiguous terms such as ‘platform’”. His bluntest line: “make it sound dumber than you think it should.”

Paul Graham’s advice on the YC application adds a shortcut. Describe the idea as a variant of something people already know: “It’s like Wikipedia, but within an organization.” “It’s eBay for jobs.” Use that as a bridge, then say what you do and for whom, because an analogy on its own doesn’t tell anyone who pays.

Real one-liners from Italian and American startups

Start close to home. Milan-based Scalapay greets visitors to its Italian site with “Quello che ami in 3 rate, senza interessi”: what you love, in three instalments, with no interest. The customer is implied, the product is clear and the obvious worry is answered before you ask. Eight words.

D-Orbit, an Italian space company founded in 2011, sells something much harder to picture. Its homepage leans on a phrase everyone already understands: “last-mile delivery of satellites”. That’s Graham’s variant trick, taken into orbit.

Across the Atlantic, Airbnb’s early pitch deck opened with “Book rooms with locals, rather than hotels.” Seven words, with the competitor built in. A clear sentence didn’t make the money easy, though. On 26 June 2008 a friend of the founders, the same Michael Seibel, introduced them to seven investors in Silicon Valley. They were trying to raise $150,000 at a $1.5 million valuation (the price put on the whole company). Brian Chesky later published the outcome: five rejections, and two who never replied.

Seibel’s own example in his pitching guide comes from a YC company: “Socialcam is a mobile app that makes it easy to take videos and share them with friends and family.” No wordplay, no adjectives. You could explain it to your grandmother.

Five rewrites: from vague to clear

To see the formula at work, imagine an invented startup in Bologna, call it Lievito, that tells small bakeries how much bread to bake each morning. Below are five first drafts a founder could easily write, what goes wrong in each, and a fix. If you’ve read our list of pitch deck mistakes, you’ll recognise the first problem on it.

First draft	What goes wrong	Rewrite
“Lievito is an AI-driven platform for the bakery value chain.”	Three buzzwords, zero facts. Who uses it, and for what?	“Lievito tells small bakeries how much bread to bake each morning.”
“Lievito helps food businesses reduce waste.”	Too wide: a supermarket chain and a corner bakery have nothing in common.	“Lievito helps independent bakeries with one to three shops throw away less bread.”
“We dream of a world where no loaf is wasted.”	A mission, not a product. What do you actually sell?	“Lievito is an app that predicts tomorrow’s sales from past receipts and the weather.”
“Forecasts, dashboards, alerts, supplier orders and a mobile app.”	A feature list. The reader has to work out the point alone.	“Every evening Lievito sends the baker one number per product: how much to bake tomorrow.”
“Bakers love Lievito.”	Can’t be checked. Love isn’t a metric.	“Four bakeries in Bologna use Lievito daily and binned a quarter less bread in their first month.”

Now stitch the best pieces together: Lievito helps independent bakeries throw away less bread by telling them every evening how much of each product to bake tomorrow. Four shops in Bologna use it daily. Two sentences, and your cousin at the wedding could repeat them.

Elevator pitch example: 30 seconds built from your one-liner

When someone says “tell me more”, you need the longer version. Keep the one-liner as your opening and add three beats: the problem as the customer lives it, how the product works, and what you’re asking for. Here’s Lievito’s, still invented:

“I’m Giulia, co-founder of Lievito. We help independent bakeries throw away less bread. Each evening a baker has to guess tomorrow’s quantities. Whatever doesn’t sell is binned or given away at closing time. Lievito reads the shop’s past receipts, the weather forecast and the local events calendar, then sends one number per product. Four bakeries in Bologna have used it since March, and in their first month they binned a quarter less bread. We’re looking for twenty more bakeries for a paid trial. Do you know one that would try it?”

Read it aloud with your phone’s stopwatch running. Over 30 seconds? Cut a clause from the middle, never the proof. And notice what’s missing: market size, the team’s CVs, the technology. Those come later, in the meeting and in the deck, where a clear pitch deck structure gives each of them its own slide.

Change the last line to fit the listener. To an investor, the ask is a 20-minute call. To a baker, a free week. To a professor, an introduction to a student who codes. Whoever it is, finish with a question they can answer with a yes.

How to test your one-liner on 10 people

You can’t judge your own sentence. You know too much. Seibel’s test costs nothing: write a two-sentence explanation, email it to a smart friend and “ask them to explain it back to you in different words”. If they need clarifying questions, he says, “you need to revise your pitch.”

Scale it up to ten people outside your field: your aunt, your barber, a classmate from another faculty, the neighbour who retired from the post office. Leave out your co-founder and other founders in your space, since they fill the gaps without noticing. Say it once. Then ask two questions. Who is it for? What does it do? Write down their exact words.

Set the pass mark before you begin, for example eight out of ten, and keep every misunderstanding. When three people take Lievito for a bakery, the sentence leans too hard on the name. If nobody mentions waste, the problem isn’t landing. Rewrite, then try ten new people, since the first ten have now heard the answer.

Your one-liner checklist

• It names one customer group you could actually go out and find.
• The problem is in the customer’s words, not in investor language.
• What you do is a verb, with no “platform”, “solution” or “AI-powered” unless that’s genuinely the point.
• One checkable fact follows it.
• You can say it in one breath, without reading.
• Most of your ten outsiders repeated it back correctly, in their own words.
• It’s identical on slide one, in your emails and on LinkedIn.

Where does this sit in the bigger picture? On our map from zero to your first round, the one-liner comes right after the business plan: the plan makes you think everything through, the sentence makes you choose.

The next step is money. The guide to your first €50,000 from friends, family and angels is where this sentence starts working, with relatives and business angels (private individuals who invest their own money) alike. When you’re ready to write to investors, see where the line goes in a cold email to investors, and keep the guide on how to raise capital in Italy at hand for who invests at which stage.
