Pitch Deck for Accelerator: 10-15 Slide Guide

Updated 6 November 2026 · Standard formula, shown below

This guide walks you through building a 10–15 slide pitch deck for an accelerator application. You’ll learn what to put on each slide, how to structure your story, and what common mistakes to avoid. By the end, you’ll have a clear, investor-ready deck that communicates your startup’s value quickly and convincingly.

What You’ll Need

Your startup’s core metrics (traction, revenue, users, etc.)
Market research data (TAM/SAM/SOM or comparable)
Financial projections (if you have them)
A clear description of your product/service and its unique value
Basic design tools (Canva, PowerPoint, Google Slides, or Keynote)
Feedback from at least one other person (mentor, peer, or advisor)

Step-by-Step

Define your narrative arc. Before you start designing, outline the story you want to tell. A typical arc: problem → solution → market → traction → team → ask. This keeps the deck focused and ensures each slide builds on the last.
Start with a strong title slide. Your first slide should include your company name, a one-line tagline, and your logo. Optionally add “Accelerator Application� and the date. This sets the tone and immediately tells the reader what your startup does.
Present the problem (Slide 2). Describe the pain point you’re solving. Use a specific user story or a compelling statistic. Avoid vague statements like “many people struggle with X.� Instead, say “Small restaurants lose 5% of revenue due to manual inventory errors.�
Introduce your solution (Slide 3). Show how your product solves the problem. Keep it simple: what is it, who is it for, and why is it better than existing alternatives? Use a screenshot or a short demo video if possible.
Show your market opportunity (Slide 4). Present your target market size (TAM, SAM, SOM) or at least a credible bottom-up estimate. Show that the market is large enough to support a scalable business. For example, “There are 500,000 small restaurants in the US, spending $2B annually on inventory software.�
Explain your product/technology (Slide 5). Go deeper into how your product works. Highlight any proprietary technology, patents, or unique algorithms. Use diagrams or flowcharts to make it understandable.
Outline your business model (Slide 6). How do you make money? Subscription, transaction fee, freemium? Include pricing if you have it. If you’re pre-revenue, explain your planned model and why it’s viable.
Show traction (Slide 7). This is critical. Include any metrics you have: number of users, revenue, partnerships, beta testers, or letters of intent. Even early traction (e.g., “100 waitlist signups in 2 weeks�) shows validation.
Analyze the competition (Slide 8). Create a simple comparison table or a 2×2 matrix. List direct and indirect competitors, and show where you differ. Be honest about your weaknesses, but emphasize your unique strengths.
Introduce your team (Slide 9). Highlight the founders and key team members. For each, include a one-line bio that explains why they’re the right person for this role. Mention relevant experience, skills, and any prior startup success.
Detail your financials (Slide 10). If you have financial projections, include a simple chart or table showing revenue, expenses, and profit over the next 3-5 years. If you’re pre-revenue, state your assumptions. Even a basic model shows you’ve thought about the numbers.
State your ask and use of funds (Slide 11). Clearly state how much funding you’re seeking (if the accelerator provides funding) and how you’ll use it. For example, “We’re raising $50K to hire two engineers and run a pilot with 10 restaurants.�
Add a roadmap (Slide 12). Show your milestones for the next 6-12 months. This demonstrates you have a plan for growth. Include product development, marketing, and hiring goals.
Include a “Why This Accelerator� slide (Slide 13). If you’re applying to a specific accelerator, explain why you want to join. Mention their network, mentors, or specific resources that align with your needs. This shows you’ve done your research.
End with a contact slide (Slide 14-15). Your final slide should include your contact information (email, phone, LinkedIn) and a call to action, like “We’d love to discuss how we can grow with your support.�

Common Mistakes

Too much text. Slides should be visual, not paragraphs. Keep bullet points to 5 words or less per line.
Ignoring the problem. Some decks jump straight to the solution without explaining why the problem matters. Always start with the pain.
Unrealistic projections. Don’t claim you’ll have 10 million users in a year if you only have 10. Be credible and show you understand the market.
Not tailoring to the accelerator. A generic deck is obvious. Customize your “Why This Accelerator� slide for each application.
Poor design. Cluttered slides, mismatched fonts, or low-quality images undermine your credibility. Use a clean template.
Forgetting the ask. If you’re seeking funding, make it explicit. Don’t leave the reader guessing what you want.

Tips

Keep it to 10-15 slides. More slides dilute your message. If you have extra info, put it in an appendix.
Use visuals. Charts, screenshots, and diagrams are more memorable than text. Ensure they’re high-resolution.
Practice your pitch. Even if you’re just submitting the deck, you’ll likely be asked to present. Rehearse until you can explain each slide in under 30 seconds.
Get feedback early. Show your draft to someone who doesn’t know your startup. If they can’t explain your business after viewing the deck, it needs work.
Use consistent branding. Use your logo, colors, and fonts throughout. This looks professional.
Highlight traction. Even small numbers show progress. Don’t hide them.

Troubleshooting

What if you don’t have traction yet? Focus on your team’s expertise, your product’s uniqueness, and any early validation like user interviews or pre-orders. Emphasize that you’re solving a real problem.

What if your market is niche? Show that the niche is underserved and has high growth potential. Use specific examples of how you can expand to adjacent markets.

What if your financials are just guesses? That’s okay for early-stage. Present them as assumptions and show you understand the key drivers (e.g., customer acquisition cost, churn).

What if you don’t have a full team? Be honest. Highlight your own skills and mention that you’re looking for co-founders. Accelerators often value a strong solo founder.

What if the deck feels too long? Cut slides that are less critical. You can always move details to an appendix.

What if you’re rejected? Ask for feedback, revise, and reapply next cycle. Many successful startups got in on a second or third try.

Frequently Asked Questions

How long should my pitch deck be for an accelerator?

Most accelerators expect 10-15 slides. This is enough to cover the essentials without overwhelming the reader.

Should I include a video or demo?

If you have a short demo (under 2 minutes), it can be very effective. Place it on the solution slide or as a link in the appendix.

What if I don’t have a business model yet?

That’s common at the idea stage. Explain your intended model and the logic behind it. Show you’ve thought about how you’ll generate revenue eventually.

How do I make my deck stand out?

Focus on a clear problem, a unique solution, and credible traction. Use a clean design and tell a compelling story. Personalize the “Why This Accelerator� slide.

Should I include my financial projections in the main deck?

Yes, but keep it simple. A one-page chart or table is enough. More detailed projections can go in the appendix.

Can I use a template from the internet?

Yes, but customize it. Templates are fine as a starting point, but your deck should reflect your brand and content.
