Test Your Skills: See If You Can Decide Like a Y Combinator Partner

Y Combinator (YC), one of the world’s most prestigious startup accelerators, has long been the gatekeeper for many of today’s most successful tech companies. Deciding which startups to fund is notoriously difficult, given that YC accepts roughly only 1% of applicants. Now, a new interactive game called the YC Partner Simulator offers the public a chance to test their decision-making skills by stepping into the shoes of a YC partner.

Developed by an undergraduate student in Berlin, the YC Partner Simulator is part of a larger suite of games known as YC Arena. The simulator presents users with real pitch videos from companies that applied to YC in previous years. Players must decide whether to “accept” or “reject” each startup and then see if their choice matches the actual decision YC partners made[5].

The game highlights the complexity and nuance involved in these high-stakes decisions. YC partners rely on a mix of objective metrics, gut instincts, and subtle cues when interviewing founders and evaluating startups. According to insider accounts, YC interviews are intense and brief—often just 10 minutes—with partners seeking to quickly gauge a founding team’s resilience, vision, and potential to dominate their market[3]. Having a strong demo ready and the ability to articulate why a startup will win in its space are crucial factors that can sway the decision.

Interestingly, the acceptance process is not purely meritocratic. Factors such as timing, partner mood, and even the order in which pitches are seen can influence outcomes, making the role of luck non-negligible. Additionally, YC partners are successful investors but not necessarily operating billion-dollar companies themselves; their role focuses on filtering for potential rather than guaranteeing success[2].

The YC Partner Simulator game also serves as a reminder that rejection from YC is not definitive. Many founders rejected by YC later built highly successful companies, underscoring that decision-making in startup investing is an inexact science with room for error[5][2].

This interactive experience not only engages entrepreneurs and startup enthusiasts but also offers valuable insight into the mindset and criteria YC partners use.
