I reviewed 2,500+ pitch decks. Here's why yours isn't ready.

Let me tell you what investors won't.

I need to be really honest with you about something.

Most pitch decks are terrible.

I don't say that to be harsh — I say it because I've reviewed over 2,500 of them, written 100+ myself, and helped provide over £1 billion in funding. I've sat on both sides of the table: pitching for capital and deciding where to deploy it.

And the pattern is always the same. Founders pour months — sometimes years — into building something genuinely good. Then they put together a pitch deck over a weekend, send it to investors, and wonder why nobody bites.

By the time you're sitting in front of an investor, it's too late to fix your deck. You only get one bite at the cherry. And most founders waste that bite on a deck that doesn't do their business justice.

What I've learned from 25 years of this

After two and a half decades of building, funding, and evaluating businesses, I can tell you the three reasons most decks fail:

  1. They tell a story nobody asked for. Investors don't care about your journey. They care about the market, the model, and the money. If your first three slides are about "the founding team's passion," you've already lost them.

  2. The numbers don't hold up. Your TAM/SAM/SOM figures need to be credible, not aspirational. If you claim a £50 billion market and you're a two-person team with £12K in revenue, investors will close the deck before slide 6.

  3. They haven't been stress-tested. Nobody has asked the hard questions before the investor does. What happens when an investor says "Why would I back you over [competitor X]?" or "Walk me through your unit economics"? If you don't have crisp answers, you're done.

A real example: what a teardown actually looks like

Last week I completed a full teardown for a client in the trades services sector. Here's what the process uncovered — and what the founder would never have spotted on their own.

The deck looked professional. Clean design, good structure, reasonable slide count. On the surface, it seemed ready.

But when I dug in:

The revenue model had a critical flaw. Their projections assumed a conversion rate 3x higher than the industry average, with no evidence to support it. Any investor with sector knowledge would have flagged this immediately.

The competitor analysis was incomplete. They'd listed three competitors. I found twelve — all were better funded and further ahead. Their "unique differentiator" wasn't unique at all.

The valuation was aggressive. They were asking for a valuation that assumed everything went perfectly for three years. I benchmarked it against comparable deals and showed them where the number needed to be.

The investor Q&A prep was non-existent. I prepared 15 questions that any serious investor would ask. The founder couldn't confidently answer 11 of them.

The result? A 40+ page branded report covering every section of the deck, the business model behind it, and a full investor readiness assessment. Plus a 30-minute personalised Loom video walking through every finding, and a coaching call with me to dig deeper.

Here are actual sections from that report:

Executive Summary — every deck gets a structured overview of strengths, weaknesses, and priority fixes.

Revenue Model Analysis — your projections stress-tested against market data and comparable businesses.

Competitor Landscape — a full market map showing where you sit and who you're really up against.

What you get

Every teardown covers three areas: the deck itself (structure, flow, investor-readiness), the business model (revenue, competition, market sizing), and investor preparation (the hard questions you'll be asked).

Specifically:

  • Slide-by-slide review — every slide scrutinised for structure, clarity, and investor impact.

  • Business model critique — your revenue model, unit economics, and growth assumptions stress-tested.

  • Revenue and market sizing analysis — are your TAM/SAM/SOM figures credible?

  • Competitor landscape research — who else is in this space and how you compare.

  • Valuation assessment — is your ask reasonable against comparable deals?

  • Investor Q&A preparation — the hard questions investors will ask, and how to answer them.

  • A branded written report with data, charts, and specific recommendations.

  • A ~30 minute personalised Loom video walking through every finding.

This isn't for everyone

If you want someone to tell you your deck is great and pat you on the back, this isn't the service for you.

This is for founders who want the unfiltered truth about what works, what doesn't, and exactly how to fix it — before they sit down with the people who write the cheques.

P.S. — I only take on a limited number of teardowns each month. Every one is done personally by me, not a team, not an AI. If you're raising in the next 3-6 months, don't leave your deck to chance.
