I’ve spent 20 years designing biotech pitch decks. I’ve also spent many of those mornings and evenings on the ice with a unicorn broom and a 42-pound granite stone. Turns out the two have more in common than you’d think.
I’m a curler. Not the hair kind. The kind that involves screaming on ice.
For the uninitiated: curling is a sport where four people take turns sliding polished granite stones down a sheet of ice toward a target, the house. Two team members sweep the ice in front of the stone to control its speed and path. A skip stands at the far end, reading the conditions, calling the shots, and trying to place each stone exactly where it needs to be.
It sounds simple. It is not. The ice is alive. It changes throughout the game. The pebble wears down, the temperature shifts, the path a stone took in the first end won’t be the same in the eighth. A good curler reads these changes constantly and adjusts.
I’ve been doing this for years. And at some point, I realized that everything I know about curling, I also know about presentation design.
Reading the ice
In curling, “reading the ice” means understanding the surface conditions before you release the stone. Where is it fast? Where is it slow? Where does it curl more than expected? You make these reads before every single delivery, because the ice is never the same twice.
A pitch meeting works the same way.
Every room is different ice. A founder who delivers the same presentation the same way in every room is throwing stones without reading the ice.
The best presenters I’ve worked with are constant readers. They notice when the energy dips and adjust their pacing. They sense when an investor is confused and slow down to explain. They feel when the room is with them and know to ride that momentum instead of interrupting it with the next slide.
You can’t script this. You can only develop it through preparation, rehearsal, and enough reps that reading the room becomes instinct. The deck gives you the strategy. Reading the ice is what makes the delivery land.
The skip doesn’t throw every stone
In a curling team, the skip is the strategist. They call every shot, decide the weight, pick the line, and place the broom where the stone needs to go. But the skip doesn’t throw every stone. In fact, the skip only throws two out of eight per end. The lead, second, and third each throw their own.
This is the part that most startup founders get wrong.
I’ve watched founders try to do everything themselves: design the deck, write the narrative, build the financial model, rehearse the pitch, handle the Q&A, and manage the follow-up. That’s a skip who insists on throwing all eight stones. It doesn’t work in curling and it doesn’t work in a raise.
The strongest biotech pitches I’ve been part of had clear roles. The CEO delivered the vision and the ask. The CSO owned the science. The CFO handled the financial questions. Each person threw their stone, and the skip called the game.
When a founder tries to handle the mechanism of action, the clinical data, the regulatory strategy, the business model, and the team narrative all by themselves, the delivery gets thin. They’re not giving any single part the weight it deserves. They’re throwing too many stones and sweeping none of them.
The skip’s job is to see the whole sheet, not to throw every rock.
Sweeping
This is the one that maps most directly to what I do for a living.
In curling, sweepers don’t change the direction of the stone. The line is set at release. What sweepers do is reduce friction. They heat the ice in front of the stone so it travels farther, straighter, and closer to where the skip intended it to go.
That’s presentation design.
A good deck designer doesn’t change a founder’s message. The vision, the science, the strategy: that’s set at release. What a designer does is reduce the friction between the founder’s idea and the investor’s understanding. Clean layouts remove visual friction. A clear narrative removes cognitive friction. Smart data visualization removes analytical friction. The Hunger Arc removes structural friction.
Every design decision I make is a form of sweeping. Typography that’s easy to read? Sweeping. Colour that shifts with the emotional arc? Sweeping. A mechanism of action spread across three slides instead of crammed onto one? Hard sweeping.
Over-designing a deck is like over-sweeping a stone: you push it past the target.
And just like in curling, you have to know when to sweep and when to let the stone travel on its own. Sometimes the founder’s words are strong enough that the slide should be nearly empty. Sometimes the data is compelling enough that it doesn’t need a fancy visualization. Knowing when to put the brooms down is as important as knowing when to sweep hard.
The house
In curling, the target is called the house. It’s a set of concentric circles, and the goal is to get your stones closer to the centre (the button) than your opponent’s.
In a pitch meeting, the button is the term sheet. And just like in curling, you don’t get there with one stone. You get there with a series of well-placed shots that build position throughout the game. The opening slide sets up the angle. The narrative builds the guard. The data draws to the button. And the ask is the final stone that scores the end.
If you’ve been following this series, that should sound familiar. The Hunger Arc is a curling end. Each slide is a stone, and they all need to work together.
Why I curl
People always ask me why I curl. It’s cold, it’s slow on television, and explaining the rules takes longer than most people’s patience allows.
I curl because it’s the most strategic team sport I’ve ever played. Because every delivery is a fresh read on changing conditions. Because the outcome depends on four people trusting each other completely. Because there’s a specific, physical satisfaction in watching a stone travel 150 feet and come to rest exactly where you wanted it. There are so many different ways to approach the sport, and my brain comes alive thinking about it.
That’s also why I design pitch decks.
A great presentation is a team of well-placed stones on a sheet of ice that’s always changing. You read the conditions, you trust your team, you sweep when it matters, and if you’ve done everything right, you’re sitting on the button when it counts.
Good curling.
