YC Arena: New Game Reveals the Surprisingly Subjective World of Startup Investing

A new interactive experience, YC Arena, offers a revealing glimpse into the high-stakes world of Y Combinator, the renowned startup accelerator. Created by a student in Berlin, the platform isn’t a clandestine gathering for founders, but a suite of games designed to simulate the decision-making processes of a YC partner.

The centerpiece of YC Arena is the YC Partner Simulator. This game presents users wiht publicly available pitch videos from companies that previously applied to YC, alongside the year of their request. players then decide whether to “accept” or “reject” each venture, subsequently learning if their judgment aligned with YCS actual decision.

Did you know?-Y Combinator partners often spend only 10 minutes reviewing each initial application, focusing on the founder’s potential.

The game quickly demonstrates a challenging reality: evaluating startups is far more complex than it appears. Y Combinator reportedly accepts around 1% of applicants, and a degree of chance inevitably plays a role. As one observer noted, a pitch’s success can hinge on seemingly arbitrary factors – whether it’s the first viewed after a partner’s coffee break or the last on a long list.

Pro tip: When evaluating startups, prioritize clarity and conciseness in pitches, mirroring advice from YC co-founder Paul Graham.

YC Arena also includes games testing knowledge of company logos and YC application years, with a notable trend toward increased artificial intelligence (AI) ventures in recent cohorts. Though, it’s the Partner Simulator that truly compels introspection, forcing players to confront their own biases and evaluation criteria.

A tech journalist testing the simulator found initial success elusive. While accustomed to sifting through pitches – having previously evaluated startups at events like TechCrunch Disrupt’s Battlefield 200 Expo in San Francisco (October 27-29, 2025) – the journalist discovered that identifying potential for newsworthiness doesn’t necessarily equate to identifying ventures poised for profitability.

“Would I put money on the bet that Casio will turn a profit off of the investment it takes to create a glorified Furby that retails for $430? No,” the journalist reflected. “Do I expect that an article about my life with an AI pet will be engaging to readers? Yes.”

The game underscored the subjective nature of the process.However, a shift in strategy – prioritizing clarity and conciseness based on advice from YC co-founder Paul Graham – yielded more accurate results. Graham famously advised applicants to “give it to us right in the first sentence, in the simplest possible terms.” This advice, it turns out, also resonates with journalists.

Interestingly, this emphasis on rapid assessment aligns with a former YC president’s outlook. Sam Altman, now CEO of OpenAI, revealed in a 2016 interview that YC partners often spend 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 stated. “Not with 100 percent accuracy, obviously, but good enough that our business model works.”
