Startup one-pager: what to send investors before the deck

Italian Angels for Growth, the Milan angel network, says it examines about 100 deals every two months. A quarter get as far as a screening with its angels. Two in a hundred end up with an investment. And the first read is short everywhere: DocSend’s data puts the time investors spend on a whole pitch deck, the slides that tell your company’s story, at under three minutes.

That first read is what a startup one-pager is for. It’s one sheet. From it a busy investor should learn what you do and what you’ve already proved, plus the size of the round. Then somebody forwards it, often to a partner who’s never heard of you and reads it cold on a Friday afternoon. Below: the naming muddle first, then the nine blocks, a filled-in example and the email that carries it. New to fundraising? Start from the beginner’s map, from zero to a first round.

What is a one-pager, and how is it different from a teaser or a deck?

Half the confusion is the names. In Italy you may meet the format first on a public form. The application for Smart&Start Italia, Invitalia’s incentive for innovative startups, has an Executive Summary section: three boxes of up to 1,500 characters each, for the company, the product and the market.

Investors want the same thing, shorter. CRV recommends ‘a one-page executive summary’ next to the deck ‘for investors who want the condensed version before diving deeper’. DocSend’s guide calls it a one-pager, and the one-page limit ‘non-negotiable’.

A teaser is another animal. In M&A (mergers and acquisitions), Euronext defines it as a short, anonymous document that tests buyers’ interest without revealing who the company is, sent before anyone signs an NDA, a non-disclosure agreement. Some founders use the word for a mini deck of two or three slides. Jason Lemkin of SaaStr isn’t a fan. ‘Don’t listen to folks who tell you send a “teaser”,’ he wrote in 2024.

Document	What it’s for	Length	When it goes out
One-pager	A first read that survives a forward	One page	With an introduction or a first email
Executive summary	The same job with a little more room; also a section of business plans and grant forms	One page for CRV and DocSend; one to two pages in a 2013 Perkins Coie guide	With the deck, or when a form asks for it (Smart&Start: three boxes of 1,500 characters)
Investor teaser	In M&A, an anonymous profile that tests interest; in startups, sometimes a two or three slide mini deck	One to two pages (IMAP)	Before an NDA, in M&A; many VCs would rather get the full deck
Pitch deck	The full story, read alone or presented	Roughly 20 pages (DocSend, 2025)	When an investor asks; for first and second meetings, CRV shares only the deck and the executive summary

For a seed round you need two of these, the one-pager and the deck. An anonymous teaser suits a company that’s being sold quietly. You want a meeting, so put your name at the top.

What goes on a startup one-pager, block by block

Nine blocks, in the order an investor’s questions tend to arrive. They follow Sequoia’s guide to writing a business plan and the seven questions Michael Seibel of Y Combinator says investors want answered. Copy the list, then cut every block to two or three lines.

1. One-liner. Sequoia’s guide starts here: ‘define your company in a single declarative sentence’. That’s your one-liner, what you do and for whom, and it sits at the top, under the name. Our guide to the startup one-liner, with examples shows how to get it down to one breath.
2. Problem. Who is in pain, and how do they cope today? Use the customer’s words.
3. Solution. What the product does, in plain terms. Seibel’s rule is to ‘eliminate jargon, acronyms, marketing speak, and any ambiguous terms such as “platform”‘.
4. Traction, with dates. Traction is proof that somebody wants the product. Paying customers count, so does revenue, and so do daily users or a signed pilot. Date every figure. Seibel judges progress as the ratio between what you’ve done and how long you’ve been at it, and he can’t do that sum without dates.
5. Market. One line, built from the bottom up: the customers you can reach, times your price. The arithmetic is in our guide to TAM, SAM and SOM, the total, serviceable and obtainable market.
6. Business model. Who pays, how much, how often. One price sticks in the memory; a pricing grid doesn’t.
7. Team. Two lines per founder on why you, of all people, can fix this.
8. The round. The amount, the instrument (equity, or a convertible that turns into shares later), the months of runway it buys, meaning how long the cash lasts, and your use of funds in two or three percentages. Seibel again: ‘If you want me to invest, ask.’
9. Contact. Name, email, mobile, website and the date of the document.

A filled-in example you can copy

Searching for a startup teaser template? At seed you probably need this instead: a one-pager with your name on it. Here’s the one for Lievito, the invented Bologna startup from our pitch deck structure guide. Every number matches its deck, and that’s the point.

Block	What Lievito writes
One-liner	Lievito helps independent bakeries throw away less bread by telling them every evening how much to bake.
Problem	Bakers set tomorrow’s quantities by feel. Whatever doesn’t sell is binned or given away at closing time.
Solution	Software that reads each shop’s till data and sends the baker tomorrow’s quantities, product by product, every evening.
Traction	Four bakeries have used it daily since March 2026 and bin about a quarter less bread (as of 30 September 2026).
Market	3,000 independent bakeries in northern Italy whose tills export data: about €2.1 million a year at our price.
Business model	Subscription, €59 a month per shop.
Team	Giulia, CEO: grew up in her family’s bakery and ran its books for six years. Co-founder and CTO: built demand forecasts for a grocery chain.
The round	€400,000 pre-seed, equity, for 18 months of runway and 300 paying shops. Use of funds: 55% product, 30% sales, 15% buffer.
Contact	Giulia’s email and mobile, the website, and the date: 1 October 2026.

How to write an executive summary for investors that gets forwarded

Expect it to travel. At Italian Angels for Growth, which has more than 300 members, the angels who back a company form a consortium, a ‘Club Deal’, for each investment, so your page reaches people you never wrote to. In a fund it moves from associate to partner. Write for that second reader: no context, no reason to be generous. Our guide to business angels in Italy and how to approach them explains how these groups screen.

Usually the page rides inside an introduction. In 2009 the venture capitalist Fred Wilson described the courteous way to make one, the double opt-in: ‘ask each of them to opt-in to the introduction before making it.’ Your contact forwards a short note with the one-pager, the investor says yes or no, and only then are you connected. Guy Vidra of Collaborative Fund asks founders for two emails, one requesting the introductions ‘and a second forwardable email’.

That second email is yours to write, and it has to work without edits. Here’s Lievito’s, invented like the company: ‘Hi Marco, here’s a note you can forward to Anna as it is. Lievito tells independent bakeries every evening how much bread to bake. Four bakeries have used it daily since March and now bin about a quarter less bread. We’re raising €400,000 to reach 300 paying shops in 18 months, and I’d value Anna’s view because she invests in food retail. One-pager attached. Thanks, Giulia.’

Under 80 words; DocSend’s guide sets the limit at 150. No one to introduce you? Read our guide to a cold email to investors that gets read, and build an investor target list to spot who in your network knows whom.

Format rules: one page, a PDF, a date

One page means one page. DocSend wants type of at least 11 to 12 points, which kills the trick we’ve all tried: nudging the font down until the last line squeezes in. Always a PDF. A partner opening it on a phone at Linate should see what you saw on your laptop.

Date it. A forwarded page can circulate for months, and ‘four bakeries’ reads differently in October than next March. For data room files, CRV’s suggested format is YYYY_QX_Document_Type_vX.X.pdf. Copy that. Lievito’s file would be 2026_Q4_OnePager_EN_v1.0.pdf, and whoever finds it in an inbox next spring knows at a glance it’s from last autumn.

Then check every figure against the deck and the financial model. CRV warns that ‘conflicting numbers are a fast way to kill deal momentum and erode trust’, and the one-pager is read first, then again next to the deck. If the deck and its numbers aren’t ready yet, our Investor-Ready Kit (€149) has a deck template, a runway model, a cap table simulator, a data room checklist and investor emails.

Assume a competitor will see it one day. Customer names you aren’t allowed to share, prices agreed under an NDA, margins by client: leave them off.

One legal point for an Italian Srl. Article 2468 of the Civil Code says Srl quotas can’t be the object of a public offer of financial products; article 100-ter of the TUF, Italy’s consolidated finance law, carves out exceptions, crowdfunding platforms included. Sending your page to investors you’ve picked is how private rounds work. Posting your round’s terms publicly with an invitation to invest is a different matter, so ask a lawyer first.

Do you need an Italian and an English version?

If anyone on your list is based abroad, yes. Growth Capital and Italian Tech Alliance count international participation at 46% of the investors active in Italian rounds in 2025, against 24% in 2020, and every round above €20 million had at least one foreign investor. Plenty of Italian angels read happily in Italian (IAG’s own startup page is in Italian). Keep both.

Line-by-line translation shows, so write each version in its own language. Then print both, put them side by side and check with a pen. Slips hide in the numbers: 1,2 milioni di euro on the Italian page must read €1.2M on the English one, the comma turning into a point, and 1 ottobre 2026 becomes 1 October 2026. Explain Srl once in English (an Italian limited liability company). Same blocks, same date, same figures, and EN or IT in the file name.

Common one-pager mistakes

• No date, so March’s traction is still doing the rounds in October.
• A figure that differs from the deck, even by a few hundred euros.
• Jargon. Perkins Coie warned against acronyms that show ‘how brilliant you are’ and against words like ‘huge’ and ‘ginormous’.
• A market that claims all of Europe. Build it from the customers you can actually reach.
• No ask. If the amount isn’t on the page, the reader has to write and ask, and some won’t bother.
• An anonymous, M&A-style page when what you want is a meeting.

Checklist before you send your one-pager

1. Write the one-liner, then run Seibel’s test: email two sentences to a smart friend and ask them to explain it back.
2. Put an ‘as of’ date next to every traction figure.
3. Check each number against the deck and the model.
4. Read it as a competitor would, and delete what you’d regret.
5. Export to PDF. Check it really is one page, with type of 11 points or more and the date in the file name.
6. Asking someone for an intro? Give them a forwardable email, under 150 words.
7. Investors abroad on your list? Do the English page from scratch, then check the figures again, one by one.

This article is general information, not legal or investment advice. How you may circulate the terms of a round depends on your company’s legal form and on who you approach: ask a lawyer before you publish anything.
