What a one pager actually is
The term “one pager” is used loosely in professional life. People call a lot of things a one pager — a brief, a summary, a product sheet, a leave-behind. What distinguishes a genuine one pager from those other documents is the constraint: it must fit on a single page, and it must be comprehensible without the aid of a presenter or a longer document.
That sounds simple. It is not. Writing well within a fixed space is harder than writing long. The one pager discipline — used seriously — is a forcing function for clarity. If you cannot explain your business, proposal, or idea on a single page, you do not yet understand it well enough to communicate it.
The best one pagers communicate the core case in under five minutes of reading time. They do not include everything important; they include everything essential. The editor’s instinct that separates useful one pagers from padded ones is the ability to identify the difference between the two.
Use cases: when a one pager is the right tool
Startup fundraising (pre-seed and seed). The one pager is increasingly the standard initial pitch document for pre-seed rounds. Before a founder sends a full deck, many investors prefer to receive a one pager — it takes three minutes to assess whether the opportunity is relevant and worth a call.
Consulting and agency proposals. A one pager that frames the problem, proposes the solution, and states the commercial ask is more likely to get a response from a busy procurement or commercial lead than a 15-page proposal. The full proposal follows once the conversation is opened.
Product announcement (internal). When a product manager wants to announce a new feature or product to internal stakeholders, a one pager is more effective than a slide deck or a long memo. The product, the problem it solves, the target user, and the success metric — on one page.
Board briefing pre-read. A one pager sent 48 hours before a board meeting, summarising a key decision item, means the board arrives already oriented. The meeting discusses rather than explains.
Grant applications. Many UK and US grant bodies request a one-page expression of interest before inviting a full application. Foundations, Innovate UK, the Wellcome Trust, and US SBIR/STTR programmes all use this mechanism.
Internal project brief. A one pager that defines a project’s problem, solution, success criteria, resource ask, and timeline is a useful internal document — short enough to be read before the kickoff meeting, specific enough to be referenced throughout the project.
The six essential sections
A well-structured one pager for a business or project covers six areas:
1. Elevator pitch / headline. One or two sentences: what you do and for whom. Not a mission statement — a description. “Carbon accounting software for UK SMBs facing CBAM compliance” is better than “We help businesses build a sustainable future.” Be specific.
2. Problem. Two to three sentences identifying the pain. Quantify it where possible — “4.3 million UK SMBs” is more persuasive than “many businesses.” The problem must be real, specific, and identifiable by the target audience.
3. Solution. Two to three sentences explaining how your product or proposal resolves the problem. Include what makes your approach different from the alternative (which is often the status quo). Avoid jargon — if the reader cannot understand the solution without domain expertise, the one pager is failing.
4. Market. A market size statement. For investors: total addressable market (TAM) and your realistic serviceable market. For internal proposals: the number of people affected, the scale of spend involved, or the magnitude of the opportunity. One number, stated confidently.
5. Traction. What has already been achieved? Revenue, users, clients, pilots, letters of intent, award, media coverage. For a brand new project: the team’s relevant credentials and any pre-validation (customer interviews, waitlist sign-ups, pilot results). Traction answers the question: why should I believe this is possible?
6. Team. Two to four sentences about the people behind the proposal. Focus on relevant expertise and track record — not job titles or educational background unless directly relevant. “Two former Deloitte partners with 8 years combined experience in SMB accounting software” is better than “MSc in Computer Science from UCL.”
For a fundraising one pager, add a seventh section:
7. The ask. What specifically are you requesting? For investment: the amount, the instrument (SAFE, convertible note, equity), the use of funds, and the runway it provides. For a grant or internal budget: the specific amount and the measurable outcomes it enables.
Design principles
The visual design of a one pager is as important as its content. A well-designed one pager signals competence and care. A poorly designed one undermines the credibility of the content.
One font family. Use a single typeface with weight variation for hierarchy. Satoshi, Inter, or Helvetica Neue for a modern look; Garamond or Caslon for a traditional professional feel. Never mix more than two typefaces on a single page.
Clear visual hierarchy. The reader’s eye should move from the headline to the key data points to the contact information in a predictable sequence. Use font size, weight, and whitespace — not colour — as your primary hierarchy tools.
Generous whitespace. A dense one pager reads as desperate or amateur. The whitespace is not wasted space — it gives the reader’s eye somewhere to rest and makes the content appear more confident.
Three to four bold data points. Numbers in a larger, bolder format (MRR, market size, user count, funding ask) anchor the document visually and draw the reader’s attention to your strongest evidence.
No more than three colours. A palette of two neutrals (dark grey for body text, light grey for backgrounds or dividers) and one accent colour is clean and professional. Four or more colours creates visual noise.
What a one pager should not include
Appendices. A one pager with an attached appendix is a two-page document in denial. If the information is essential, it goes in the one pager. If it is not essential, it is not included.
Micro-font text. Reducing font size below 9pt to make the content fit is counterproductive. The reader will not read sub-9pt text in a one pager — they will conclude that you either do not understand what is important or that you cannot edit.
Excessive caveats. “We believe we may potentially be able to achieve…” One pagers are assertive documents. Caveat where legally necessary; otherwise, state your case.
Logos of all your competitors. Competitive positioning is relevant; a visual display of competitor logos is not. Mention the competitive landscape in a single sentence if necessary.
Common mistakes
Mistake 1: Too many words. A one pager where every square centimetre is covered in text is not a one pager — it is a dense memo formatted to fit one page. Whitespace is part of the design.
Mistake 2: Burying the ask. Investors and decision-makers read for the ask first. If the ask is at the bottom of the page in the smallest type, buried after four paragraphs of context, it will not register. Put the ask — amount, purpose, instrument — clearly visible in the document.
Mistake 3: Generic problem statement. “Businesses struggle with inefficiency” describes every business in history. A problem statement must be specific enough that the target audience immediately recognises it as their problem.
Mistake 4: No traction or validation. A one pager that describes a problem and solution with no evidence that either is real asks the reader to take the entire premise on faith. Include the earliest evidence of validation — even 50 customer interviews constitute traction.
Mistake 5: Wrong format for the context. A beautifully designed landscape Figma one pager sent as a .fig file attachment to an investor who uses Gmail on mobile is inaccessible. Always send PDF, always in portrait, always sized for reading without zoom.
Worked example: Nova Labs pre-seed one pager
Nova Labs | carbon.noalabs.io | jamie@novalabs.io | +44 7700 900321
Auto-compliance for the carbon age.
Nova Labs builds carbon accounting software that auto-imports Scope 1–3 emissions data directly from Xero and QuickBooks — eliminating the manual spreadsheet work that currently consumes 40 hours per SMB per reporting cycle.
The problem. 4.3 million UK SMBs face the EU Carbon Border Adjustment Mechanism (CBAM) by 2027. Current solutions require a consultant, a full ERP implementation, or 40+ hours of manual data entry per quarter. 94% of affected SMBs have not yet started compliance.
The solution. One-click Xero/QuickBooks integration. Auto-categorises transactions to Scope 1, 2, and 3 using Nova’s transaction taxonomy. Generates audit-ready CBAM compliance reports in 12 minutes. No consultant. No ERP. £49/month.
Market. £2.1B UK SME accounting software market. 180,000 UK exporters directly exposed to CBAM Phase 1 (steel, cement, aluminium, fertilisers, hydrogen). Our serviceable market: 42,000 SMB exporters with Xero or QuickBooks integration.
Traction. 47 pilot customers across manufacturing, distribution, and food export. £18,400 MRR. 3 enterprise pilots (>500 employees) via Xero partner referral. NPS 71.
Team. Jamie Okafor (CEO) — ex-Deloitte Climate Risk, 6 years. Priya Mehta (CTO) — ex-Octopus Energy platform team, 5 years. Ruth Ashby (COO) — ex-KPMG Sustainability, built KPMG’s UK ESG reporting practice.
The ask. £800k pre-seed. £550k product and engineering (3 engineers, 18 months). £150k customer acquisition (Xero/QuickBooks partner channel). £100k opex. Target: £100k MRR by December 2026. Terms: SAFE, £4M valuation cap.
Format: A4 portrait. Satoshi font (free). Two-column layout for Problem/Solution/Market/Traction sections. Body text 11pt. Bold section headers 12pt. Three accent data points in 18pt bold: £18,400 MRR / 47 pilots / £800k ask. One accent colour (dark teal). 280 words. Fits cleanly on a single A4 page at 1.5cm margins.
