What is an investment teaser?

An investment teaser is a one-page summary of your company and your raise, designed to be read before any NDA is signed. Its only job is to earn the next step, a deck request or a meeting, and to be easy for an investor to forward internally. It is not a compressed pitch deck and it is not a diligence document.

What should you leave out of a teaser before an NDA?

Leave out anything you would not want a competitor to read: customer names covered by confidentiality clauses, granular financial models, your cap table, proprietary technical detail, and valuation expectations. State the size of the raise, but keep sensitive material for the data room once genuine interest is established.

How do investors read an investment teaser?

In seconds on the first pass. Most investors scan the one-line description, the traction numbers and the ask, then decide whether to read properly or move on. If those three elements do not survive a ten-second skim, the rest of the page is never read, however good it is.

How long should an investment teaser be?

One page. A teaser exists to be skimmed in ten seconds and forwarded in one click; a second page halves the chance of either. If the material will not fit, the fix is cutting detail that belongs in the deck or data room, not adding a page.

Is there a template for an investment teaser?

Yes. A working teaser template runs: a one-line overview, the problem, the solution, two or three traction numbers, the market wedge, one line per founder, headline financials, and the ask. This guide includes a copy-paste version with placeholder text for each of the eight sections.

How to Write an Investment Teaser: Template, Example & 8 Sections

The investment teaser is the most under-rated document in a raise. Your deck gets the meetings and your data room closes them, but the teaser is what actually travels: it is the page an investor reads before deciding you exist, and the page a partner forwards to a colleague with "worth a look?". This guide covers what a teaser is, the eight sections that matter, what to leave out before an NDA, the mistakes that get teasers deleted, and how investors really read them.

What an investment teaser is

A teaser is a one-page, pre-NDA summary of your company and your raise. Its only job is to earn the next step: a deck request, a call, an internal forward. It is not a shrunken pitch deck, it is not a diligence document, and it does not need to answer every question. It needs to make a stranger want the answers. Because it is pre-NDA, it is written on the assumption that anyone, including a competitor, might eventually read it. That assumption is liberating: it tells you exactly what belongs on the page and what does not.

The 8 sections that matter

A teaser that works almost always contains the same eight elements, in roughly this order:

Overview: one or two lines saying what the company does, for whom, and why now. If a reader only gets this far, they should still be able to describe your business.
Problem: the pain you solve, stated concretely. One sharp sentence beats a paragraph of industry context.
Solution: what you actually sell and how it removes the pain. Plain language, no architecture diagrams.
Traction: your two or three strongest numbers: revenue, growth rate, customers, retention. This is the section investors read first, whatever order you put things in.
Market: the size of the opportunity and the wedge you are taking into it. A credible bottom-up number beats a giant top-down one.
Team: why these founders win this market, in a line or two per person. Relevant experience, not job titles.
Financials: headline historicals and a simple forward view. Direction and momentum, not a five-tab model.
Ask: how much you are raising and what it funds. A teaser without an ask is a brochure.

Keep every number identical to your deck and model. Inconsistency between documents is the fastest way to lose trust in diligence, a point we also make in how to raise a seed round.

The copy-paste template

Replace the brackets, keep it to one page, and delete any line you cannot back with a real number. Plain formatting travels better than a designed PDF: it forwards cleanly and reads on a phone.

[COMPANY NAME] — [one line: what you do, for whom, and why now]

THE PROBLEM
[The pain, in one concrete sentence. Who has it, what it costs them.]

THE SOLUTION
[What you sell and how it removes the pain. Plain language.]

TRACTION
- [Revenue or usage headline, e.g. £62k MRR, up 14% m/m]
- [Customers or logos, anonymised where needed]
- [Retention, margin or the number your model lives on]

MARKET
[Bottom-up size of the wedge you are taking, one or two lines.]

TEAM
- [Founder, one line: the experience that wins this market]
- [Founder, one line]

FINANCIALS
[Headline historicals and a simple forward view, e.g. FY25 £0.4m
revenue, FY26 run-rating £1.1m. Direction, not a model.]

THE ASK
Raising [£X]m to [what it funds, in one line].
Contact: [name, email]

A worked example, section by section

Here is how the top of that template reads filled in for a fictional B2B company, because the difference between a placeholder and a sentence is where most teasers go wrong:

Overview: "Fieldsmith automates safety-compliance paperwork for mid-size construction firms, cutting site-audit admin from days to minutes."
Problem: "A 200-person contractor spends roughly £180k a year producing compliance evidence by hand, and still fails spot audits."
Traction: "£62k MRR, up 14% month on month; 41 contractors live including two of the UK's ten largest; 118% net revenue retention."
Ask: "Raising £2m to expand the sales team and ship the insurer integration; term sheet conversations open now."

Every line is concrete, competitor-safe, and skimmable. The reader can describe the business, believe the momentum and understand the ask without a single follow-up question, which is exactly the bar.

What to leave out pre-NDA

The pre-NDA test is simple: would you be comfortable if a competitor read this page? If not, it goes in the data room, not the teaser. In practice that means leaving out:

Customer names covered by confidentiality clauses. "A top-five UK retailer" carries the signal without the breach.
The detailed financial model and unit economics workings. Headlines on the teaser, workings later.
Your cap table and individual shareholdings.
Proprietary technical detail: the fact that the technology works and is defended matters, the how does not belong here.
Valuation expectations. State the raise amount, let the market price it.

All of that material still needs to exist and be organised before investors ask for it: our seed round data room checklist covers exactly what goes where.

Common mistakes

The same errors kill most teasers. Two pages instead of one: nobody forwards a document they have not finished reading. Jargon in the overview, so the reader never learns what you actually do. Burying the traction below the fold. Numbers that disagree with the deck. Sending the teaser as a heavy attachment rather than a clean link, which also costs you the ability to see who opened it. And the most common of all: no ask, leaving the investor unsure whether this is a raise, a partnership pitch or a newsletter.

How investors actually read teasers

In seconds, the first time. An investor triaging inbound scans the one-liner, jumps to the traction numbers, checks the ask, and makes a keep-or-kill decision in roughly ten seconds. Only teasers that survive that skim get a proper read. So design for the skim: bold the numbers, keep the one-liner honest and concrete, and put nothing important in dense paragraphs. The teaser then goes to every name on your list, so build that list properly first, covered in how to build an investor list, and send it through investor outreach so you can see who opened it and follow up on engagement rather than guesswork. The investors who read but do not bite now are tomorrow's warm contacts: keep them close with a regular investor update email.

The short version

One page, pre-NDA safe, eight sections: overview, problem, solution, traction, market, team, financials, ask. Nothing confidential, nothing inconsistent with the deck, and everything readable in a ten-second skim. If you would rather not fight a blank page, dealOS drafts the full eight-section teaser from your pitch deck and matches it against 18,000+ investors via investor matching, with pricing that starts free.
