A Berlin undergraduate has built YC Arena, a game that puts you in the shoes of a Y Combinator partner evaluating real startup pitches. The YC Partner Simulator shows actual application videos and challenges players to guess whether the company got accepted - revealing just how brutal and subjective the selection process really is.
Welcome to the brutal world of startup selection, gamified. A Berlin undergraduate has created YC Arena, and its flagship YC Partner Simulator is giving wannabe investors a reality check about how hard it is to spot the next unicorn.
The game is deceptively simple. You watch a real pitch video from a company that applied to Y Combinator, see the year they applied, then click "accept" or "reject." The twist? You're judging companies that have already been through YC's gauntlet, so you'll quickly find out if your instincts match those of the world's most famous startup accelerator.
Spoiler alert: it's harder than you think. Y Combinator accepts roughly 1% of applicants, and as TechCrunch's Amanda Silberling discovered, even experienced tech journalists struggle with the simulator. The game forces you to confront an uncomfortable truth - at YC's selection rates, luck plays a bigger role than anyone wants to admit.
"Maybe your pitch is the first that a partner watched after a very rejuvenating coffee break, or maybe your company is the last video on the list, and everyone's tired," Silberling noted after trying the game herself. The simulator includes a sobering reminder: "Many rejected founders went on to build incredibly successful companies afterwards. Rejection means nothing – even the most successful founders got rejected multiple times."
The game's educational value becomes clear when you dig into YC's actual decision-making process. When OpenAI CEO Sam Altman ran YC as president, he revealed the accelerator spent just 10 minutes reviewing each application. "It turns out that in 10 minutes, if the only question you're trying to answer is, 'Does this person have the potential to be the next Mark Zuckerberg?' … You can answer that question in 10 minutes," Altman said in 2016.
This time constraint explains why YC co-founder Paul Graham's application advice emphasizes brutal clarity: "You have to be exceptionally clear and concise. Whatever you have to say, give it to us right in the first sentence, in the simplest possible terms." Silberling found her accuracy improved dramatically when she focused less on what companies were building and more on how quickly they explained it.
