It’s 2026, and we are in no shortage of ideas.
Every founder has one. Investors hear hundreds every week. Social media is filled with predictions about the next trillion-dollar market, the next platform shift, the next company that will redefine an industry.
What's scarce isn't ideas. It's sustained belief, and the discipline to turn that belief into execution.
Last weekend at YC Startup School in San Francisco, that idea surfaced again and again.
Across conversations with founders and talks from leaders including Jensen Huang (NVIDIA) and Sam Altman (OpenAI), one theme kept emerging: the companies that go on to define industries rarely begin with ideas everyone agrees on.
At the start, these companies didn’t exactly have unique ideas. Plenty of people thought about autonomous driving, AI, programmable graphics, internet payments, and reusable rockets. What was scarce was the ability to communicate an unpopular vision well enough that a small group of people committed to it before everyone else did.
Scaling an unpopular idea isn’t just an innovation problem. It’s a communication problem. Before product-market fit, the company has almost nothing except an explanation of why its future should exist. And every transformative company has to survive a period where there’s not enough evidence for the market to believe in it yet.
And the first communications challenge is a fundamental one: can you explain an unconventional idea well enough that the right people—your co-founders, earliest employees, first investors, and earliest customers—believe in it before consensus exists?
Each speaker approached the question differently, but their answers converged around four recurring themes.
1. Conviction is earned through data. Earn the right to tell the story before you do.
A misconception about conviction is that it means refusing to change your mind. The speakers at YC Startup School described something closer to the opposite: holding onto the vision while relentlessly questioning everything underneath it.
Sam Altman recalled that, in OpenAI’s early years, “we had increasing data points to convince ourselves we weren’t delusional.”
Confidence only becomes stronger because the evidence keeps accumulating.
Jensen Huang describes the same process from NVIDIA’s earliest days. “The choice of our technology that we started the company with was absolutely wrong,” he said. “The algorithm was exactly wrong.”
Rather than defending a failing approach, Huang told his team, “We won’t have a company if we don’t confront the fact that this doesn’t work.”
The company raised money before it even knew the right technical solution. “We actually started the company, raised money, and bought textbooks,” he joked.
Yet Huang never described these pivots as abandoning the vision. He describes them as returning to first principles. “This is simply about asking questions, reasoning about things from first principles,” he said. “If this, then what? If this can get better, then so what?” The technology changed, but the questions didn't. As long as you understand the underlying problem, “everything kind of makes sense over time.”
That’s the distinction founders often miss. The implementation should change as new evidence emerges. First principles shouldn’t. The strongest narratives are built by showing how new evidence continues to reinforce the same underlying principles.
2. Build believers before you build consensus.
One of the advantages of an unpopular idea is that very few people care enough to compete with you.
Altman reflected OpenAI’s early years this way: “It was an incredible gift because it meant we didn’t have massive competitors, and we had time to do our research and build our stuff and build our company.”
It’s an inversion of conventional startup advice. Founders often assume broad attention is validation. In reality, widespread enthusiasm can mean you’re entering an increasingly crowded market.
As Altman put it, “If you’re starting the same startup as everybody else, you get a lot of hype and you can raise a lot of money, but those are much less frequently the big outcomes.”
The first communications challenge isn’t persuading everyone, but persuading the handful of people who matter most—your earliest hires, your first customers, your first investors.
For younger teams, early storytelling should be focused rather than broad. The goal is to give a small group of people enough clarity and confidence to take a leap while the company is still earning proof.
Building the story early, therefore, is strategically essential. It brings the right early people into the vision.
3. Belief has to scale internally before it scales externally.
Perhaps the most memorable line from the weekend came from Altman: “We used to joke that only 50 people in the world believed AGI was possible, but it was okay because 45 of them worked at OpenAI.”
Before an idea spreads across an industry, it has to become deeply shared within a company.
That doesn’t mean ignoring outside perspectives. Altman immediately offered the caveat. “If you can’t find anybody else that shares your belief, you should pay attention to that.”
He immediately followed it with the opposite warning, “If everybody believes it, that’s also a bad sign.”
Somewhere between isolation and consensus is the narrow window where transformative companies are built.
For founders, that means the first audience isn’t the market. It’s the team. Alignment is what allows conviction to survive long enough for everyone else to catch up. If employees can’t consistently explain why the company exists and why its vision matters, customers and the media won’t either.
4. Let the market underestimate you.
The strongest companies represented at YC Startup School didn't overcome skepticism despite being dismissed. In many ways, they benefited from it.
Altman recalled: "For years at OpenAI, it felt like we knew the biggest secret in the world. Everybody was calling us an idiot."
He laughed about how critics warned OpenAI would "single-handedly cause another AI winter." His conclusion was surprisingly simple: "If you do anything that matters in the world, you will have a lot of people call you an idiot."
Later, he explained why that period mattered so much: "Saying the heretical thing was probably why those people wanted to all be together."
That's what makes an unpopular idea so powerful. It acts as a filter. It attracts the people who are motivated by the problem itself rather than by momentum.
For communications teams, that's an important distinction. The goal isn't to manufacture consensus before it's earned. It's to decide who needs to believe, when. The best communications strategy sometimes isn’t maximizing awareness, but deliberately speaking to a small audience while the company earns the evidence for a broader story.
Scaling an unpopular idea is communicating a vision clearly enough that the right people believe at the right moments.
Or, as Altman put it, "Be grateful that the world doesn't understand. They will eventually."
