Last year, out of 50,000+ applications,
Y Combinator funded just 450 startups.
That is less than 1% acceptance rate, being one of the top most competitive incubators. Y Combinator (YC) is highly selective because its entire model depends on backing a small number of exceptional, fast-moving founders. To maintain the quality of mentorship, protect its strong global reputation.
YC keeps the bar extremely high and selects only the teams showing rare potential, execution speed, and clarity of insight.

YC portfolio
YC invests in multiple similar companies
Over the years, Y Combinator has invested in 14 companies in the payment gateway niche. Stripe leads globally, with Razorpay a close second. The same applies to the travel sector, with Airbnb leading the segment, followed by Let's Do It.

So, what is the secret?
Now we know that Y Combinator funds multiple startups with nearly identical ideas. It seems wasteful. Confusing. At first glance, it seems like a mistake—or at least inefficient. But what if there's business to it.
To understand this, let's look at 5 companies Y Combinator invested in the ‘payment gateway’ space.

What looks like redundancy is actually the only rational strategy in a hits-driven business. YC knows that most investments will fail or return modest multiples. They're not trying to avoid failure but they're trying to ensure they're in the room when exponential success happens.
You don't need five wins. You need one Stripe, one Airbnb, one DoorDash. That single outlier will generate returns that make every loss, every write-off, every failed bet completely irrelevant.
That's why YC bets on similar ideas, back competing startups, and invest in spaces that look crowded. They're not hoping lightning strikes. They're buying enough lottery tickets to guarantee they're holding the winning number.
CEO, Gary Tan says
Investing in founders rather than companies





Tan points out that the best founders don’t treat their startup as a fixed concept but as a constant experiment. YC’s job, therefore, isn’t to predict which idea will work—it’s to back the people who will find the idea that works. That’s why YC’s track record isn’t defined by perfect ideas, but by resilient, adaptable founders who turn iterations into success stories.
Inside the founder's mindset
What are the YC founders actually like?
Across hundreds of YC interviews, a consistent founder mindset appears. These aren’t just good builders, they’re people who think long-term, stay close to users, move quickly, and constantly unlearn habits that slow them down. YC repeatedly selects for this pattern because it tends to produce founders who can survive early chaos and still make something people want.

The themes above show up again and again: focus, frugality, intuition, conflict avoidance, growth instincts, action bias, and the ability to push through stress. Founders talk openly about loneliness, failed first versions, awkward conversations, lifestyle inflation, and the challenge of staying in control.
On the growth side, they prioritize customer love, product-market fit, strong culture, and small early teams that move fast. Whether it’s pruning features, hiring deliberately, or designing with users in mind, YC founders share a playbook built on resilience, clarity, and relentless iteration.

Most common path to be a YC founder
A significant proportion of YC founders hail from computer science and engineering (CSE) backgrounds, frequently emerging from prestigious institutions such as Stanford, MIT, and other leading universities. Many of them also bring experience from major technology firms, having honed their skills at companies like Google, Facebook, or Microsoft before embarking on their entrepreneurial journeys.
Alternatives
YC is not the only option
YC is one of the best-known startup accelerators, but it’s not the only path. Founders can scale through alternative accelerators like Techstars, 500 Global and Antler.
Each specialising in different strengths such as mentorship, early cofounder formation, growth support, or enterprise partnerships. The right choice depends on your stage, geography, and go-to-market needs, not just brand recognition.
