Madam Speaker, honourable members of the house, I rise in favour of the motion.

A startup exists to solve a problem for real people. Not to describe a solution. To deliver one. And the fastest way to prove you can deliver is to build the thing and put it in front of someone. That is the demo. The pitch deck comes after, because the pitch deck is only as good as the reality behind it.

Consider what a demo forces you to do. It forces you to confront whether the idea actually works. A deck lets you hide. You can write "AI-powered platform" on a slide and no one can check it. But a demo cannot lie. Either the button does something or it does not. Either a user clicks through or they close the tab. Building first drags you out of fantasy and into the world as it is.

Look at how the best companies began. Dropbox is the classic case. Drew Houston could not easily demonstrate his file-syncing product in a room, so he made a simple video showing it working. That video went out before any grand fundraising theatre, and it drew a wave of sign-ups overnight. The working thing spoke louder than any slide could. Airbnb's founders built and rebuilt their site, and famously went door to door, photographing flats, learning what hosts actually needed. They were shipping and touching reality long before investors took them seriously.

Now, my opponents will say the deck comes first because you need money to build anything at all. This is their strongest point, and I respect it. But consider what raises money today. Investors are drowning in decks. Every one promises to change the world. What cuts through is traction. A live product. Real users. A demo you can watch. The deck that works is the deck that says "here is the thing, and here is who is already using it." You cannot write that line until you have shipped.

Shipping first also protects the founder. Building the demo teaches you whether you even want to run this company. It reveals the technical walls, the awkward user, the feature nobody wants. Better to learn that in a fortnight of building than after a year of raising against a beautiful lie.

And shipping first respects the customer over the financier. It says the point of this venture is the product, not the performance. The deck is a story about value. The demo is the value itself. Stories should follow substance, not replace it.

Build the thing. Put it in someone's hands. Then, and only then, open your laptop and make the slides.

I beg to propose.

Mr Speaker, this house should reject the claim that any startup must ship a working demo before it prepares a pitch deck. The deck comes first because it forces founders to define the problem, the market size and the path to revenue in clear terms that investors can assess quickly. A half-built product cannot do that work on its own.

Consider the early days at Airbnb. The founders circulated a short slide deck that explained why existing hotel booking left travellers without options during large events. That deck secured their first small cheques from angels who had never seen a live booking flow. Only after that capital arrived did they build and test the actual site. Had they waited until a demo existed, they would have spent months coding features no one had yet agreed to fund.

The same pattern appears at many seed-stage firms backed by Y Combinator batches. Applications are judged on written answers and simple slides, not on deployed code. Investors read those materials in minutes and decide whether to schedule a call. A buggy or incomplete demo shown at that stage risks creating the impression of poor execution before the team has even explained its thinking.

The proposition will argue that a live demo proves technical competence. That point carries weight when the product is already close to launch and the round is large. Yet most startups seek their first money precisely because the product does not yet exist. Requiring a shipped demo before the deck therefore reverses the logical order: it demands evidence of execution before anyone has confirmed the idea merits execution at all.

Founders also protect themselves by leading with the deck. A public demo can reveal core algorithms or user-acquisition tricks to competitors who face no obligation to treat the material as confidential. A private deck shared under a simple non-disclosure agreement keeps those details inside the room until funding terms are discussed.

Finally, the deck itself becomes the tool that attracts the right co-founders and early hires. Engineers and designers read the slides and decide whether the vision justifies their time. A demo without that surrounding narrative often leaves them uncertain why the product should matter beyond its immediate features. The sequence that begins with the deck therefore aligns investor interest, team assembly and product development in the order that conserves scarce early resources.

Which side won?

You have heard both. The question is not which side you already agreed with.

Nothing is being collected. Your click is counted on this device and goes nowhere else.

How this was made

Every speech on this page was written by the model named beside it, from a brief giving it only its own side of the motion. No speech was edited, reordered or improved afterwards, and no speaker saw another’s text. The motion was chosen by the person who requested this debate; the models were chosen by the house because they are different companies’ models, not one model arguing with itself. Nothing here is the view of Ontold or of anyone who works here.
