Startup pitch workshop

Your AI-built startup doesn’t need another feature. It needs a pitch.

Learn how to structure and deliver a startup pitch that investors, judges and audiences can actually understand — and leave with a step-by-step checklist to fix your own deck.

For early-stage founders building their first investor pitch.

You don’t leave with notes. You leave with a checklist.

The last stretch is a step-by-step pass over your own deck — not a set of principles to apply some other time.

01

A checklist for your own deck

Every mistake we cover comes with the check that catches it, in the order to apply them. You start running it during the session, slide by slide, on the deck you brought.

02

A structure, not a script

The pitch gets built so you can rebuild it live. That is the part that holds when someone interrupts you on slide three and never lets you back to slide four.

03

A rewritten opening and close

The two moments that decide whether the middle even gets heard: how you open, and what you actually ask for at the end.

ChatGPT is not going to stand on the podium with you.

The building got easy. The part where someone has to believe you is still yours — and it happens in about three minutes, in a room, in front of people.

Five mistakes founders keep making — and what to do instead

Every one of these quietly costs you belief in the room. Every one is fixable in an afternoon, once you can see it.

  1. Leading with features instead of outcomes

    You walk through what the product does, roughly in the order you built it. The room is still trying to work out why any of it matters.

    → Open on the change you create, and keep the tech where it belongs.

  2. Saying your product is “for everyone”

    The biggest market sounds like the biggest opportunity. To an investor it reads as “this founder hasn’t found their customer yet.”

    → Narrow it until it feels risky — and watch belief go up, not down.

  3. A market size slide that works against you

    A $50B number you can’t defend costs you more credibility than it buys, and it is the slide people interrupt you on.

    → Put a market you can actually reach on that slide, and defend it.

  4. A pitch that’s memorized, not understood

    Rehearsed lines hold right up to the first hard question. Then the structure disappears, and your confidence goes with it.

    → Build on a structure you can rebuild live, so Q&A is where you win.

  5. Ending without a clear ask

    Most pitches end on “thank you”. Nobody in the room knows what you want from them, so nothing happens next.

    → Close on one specific ask that is easy to say yes to.

Bring your deck if you have one. Each of the five comes with the check that catches it, and the last stretch is you running the whole checklist down your own slides.

Who this is for

This is for you if…

  • You have a pitch coming up — investor meeting, Demo Day, accelerator interview or a startup competition.
  • You have built something real, with or without AI, and you struggle to explain why it matters in three minutes.
  • You have a deck, and a quiet feeling that it isn’t landing.
  • You are pre-seed or seed, and this is your first serious round.
  • You want a structure you can adapt to your own business, not a script to recite.

This isn’t for you if…

  • You want a business plan, a financial model or tactics for finding investors. This is about the pitch itself.
  • You want someone to redesign your slides. We work on what you say, not on gradients.
  • You want a template to copy without thinking about your own business.
  • You are past Series A, with a pitch that already closes rounds.
  • You’re collecting another resource you won’t open. It runs 60 minutes in one sitting, and it only works if you sit through it.

40+ pitches, and counting

Who’s running this

I’ve given 40+ startup pitches in front of hundreds of people — investors, people from the startup ecosystem and industry professionals. I’ve been to San Francisco to learn from founders and how they pitch. And I’ve made every one of these five mistakes myself, usually in the room where it mattered most.

This training is those lessons turned into a practical framework you can run on your own pitch, in 60 minutes.
