Investors see hundreds of pitch decks. Here’s what separates the ones that get funded from the ones that get passed.
The reality of pitching
After reviewing thousands of pitch decks from founders across Cybersecurity, Financial Infrastructure, Defense Tech, Dual Usage and Deep Tech, I have learned this: venture capitalists spend an average of less than 3 minutes reviewing your materials. According to DocSend’s 2024-2025 analytics, that number is actually 2 minutes and 14 seconds on first-pass review.
In those 180 seconds, they’re not just evaluating your business, they’re evaluating whether you understand how to build a fundable company.
The founders who succeed at startup fundraising understand that pitching is not about presenting information. It’s about answering the questions investors we are actually asking:
- Is this founder capable of building a venture-scale business?
- Does this founder understand their market well enough to win?
- Will this company justify the time and risk of writing a check?
After years of sitting on both sides of the table, I’ve identified five mistakes that kill most pitches. Here’s what they are and how to avoid them.
Mistake 1: Treating the Pitch deck as a presentation, not a conversation
Most first-time founders rehearse a 20-slide deck and deliver it sequentially without pausing (sometimes almost without breathing !!!). This is wrong (and also unhealthy :-).
A pitch is a conversation where the pitch deck provides structure, not a script. Investors will interrupt. We will ask questions out of order. We will skip slides. If you’re rigidly following your deck instead of responding to the room, you’ve lost control. They are in control or even worse you lost their attention
Research shows that decks longer than 15 slides see 40% lower engagement from investors. But length isn’t the only issue—rigidity is the bigger problem.
The fix: Practice your pitch in any order. Have someone randomly call out slides and make you explain that section without context. The deck is your map, but you need to know the territory well enough to navigate without it. And breathe.
Mistake 2: Confusing traction with activity
Founders love to showcase metrics: users acquired, emails sent, partnerships signed. But investors seeking early-stage investment don’t care about activity. They care about traction.
Activity is the work you’re doing. Traction is evidence the market wants what you’re building.
The difference:
- Activity: “We’ve signed 12 pilot customers.”
- Traction: “We’ve signed 12 pilots, 8 converted to paid contracts, average contract value €25K, 6-month sales cycle.”
Activity shows effort. Traction shows problem-solution fit.
The fix: For every metric, ask: “Does this prove the business works, or just that we’re busy?” Show metrics that matter: revenue, retention, CAC, LTV, conversion rates, growth rate. If those don’t exist yet, be honest about your stage and what you’ll prove with the capital (and when).
Mistake 3: Pitching the product instead of the business
Technical founders, especially in Cyber and Deep Tech, spend 60% of the pitch explaining how the product works and 10% explaining how the business works. This is backwards.
We aren’t buying your product. We´re buying equity in a company that will return our funds. We need to understand the business model, go-to-market motion, competitive landscape, and path to scale (10x, 10x anyone) —not technical implementation.
The fix: Spend 20% of the pitch on what you built and 80% on why it matters, who will buy it, how you’ll reach them, what it costs to acquire a customer, and how the business scales. Product features go in the appendix.
Mistake 4: Presenting unrealistic financials or ignoring them entirely
Some founders avoid projections, thinking early-stage investment decisions don’t require them. Wrong. Every institutional investor expects a financial model at pre-seed.
Others present hockey-stick projections €500K revenue today, €50M in three years with no explanation of how growth happens. Also they just show empty % on how they will spend the capital of the round, lacking detail and even worse true understanding on how the business will scale with this money
What kills credibility:
- Projections with no path to get there
- Assuming CAC stays flat as you scale
- Forgetting revenue ≠ cash
- Ignoring burn rate and runway
The fix: Build a bottoms-up model starting with unit economics: CAC, LTV, gross margin, churn. Model how these change as you scale. Be honest about what you don’t know. Investors prefer “we’re still figuring out CAC, early data suggests €2K” over made-up numbers.
Mistake 5: Failing to articulate why you, specifically, will win
VCs see similar ideas constantly. If you’re building in Cybersecurity, Financial Infrastructure, Defense Tech, Dual Usage and Deep Tech, we’ve seen 3-5 companies pitching something adjacent (at least)
The question isn’t “Is this a good idea?” It’s “Why will you win?” What makes your team special and the winning horse ?
Investors want an unfair advantage:
- Domain expertise (10 years in-industry understanding)
- Network access (relationships competitors can’t replicate)
- Technical differentiation (genuinely hard to copy)
- Timing (market changed to make this viable now)
- Team (built companies before, rare skills, worked together before, why you are special at the end of the day )
The fix: Weave throughout your pitch deck why you’re the team that wins. Be specific. “Deep industry connections” is vague. “Our CTO built fraud detection at Feedzai , CEO ran enterprise sales at Onum” is a real advantage.
A final thought
After years of witnessing startup fundraising processes, I know this: most pitches fail not because the idea is bad, but because founders didn’t answer the questions we investors are actually asking.
Consider the scale: VCs review between 500-1,000 pitch decks annually, with only 1 in 400 pitches securing funding. The ones that succeed share one thing in common: they show up prepared.
The founders who raise capital show up with evidence, a clear plan, and a credible answer to: “Is this worth betting on?”
