Y Combinator (YC) remains a dominant force in shaping the future of startups. During the highly anticipated 2025 Winter Demo Day, CNBC’s Kate Rooney interviewed Garry Tan, YC’s president and CEO, to discuss how the accelerator’s support for early-stage companies has evolved, the growing influence of artificial intelligence (AI) in the startup ecosystem, and the distinctive characteristics of this year’s startup cohort.

The Evolution of Y Combinator’s Startup Support
Y Combinator has been critical in launching some of the most successful startups, including Airbnb, Dropbox, and Stripe, for nearly two decades. Over time, YC’s approach to supporting startups has evolved significantly, adapting to the ever-changing entrepreneurial landscape.
Beyond Seed Funding: Comprehensive Startup Support
Initially, YC focused on providing seed capital and a three-month program to help startups refine their business ideas. However, its support now extends beyond funding, offering long-term mentorship, guidance on scaling, hiring strategies, and industry navigation. This ensures startups are well-equipped for success beyond the accelerator phase.
Expanding Global Reach
YC has also expanded its focus to include international startups. In recent years, entrepreneurs from Asia, Europe, Africa, and Latin America have increasingly joined the program. This shift highlights the rise of global entrepreneurship, allowing YC to tap into emerging markets while fostering a more diverse startup ecosystem.
AI’s Growing Influence on Startups and the Tech Industry
Artificial intelligence is rapidly transforming the startup landscape, and this year’s YC batch reflects that trend. AI-driven startups are gaining traction, leveraging machine learning, natural language processing, and automation to build innovative solutions.
AI as a Core Business Model
Many startups in the 2025 Winter batch are not just integrating AI as a feature but building entire business models around it. AI applications span various industries, including:
- Healthcare – AI-powered diagnostics, personalized medicine, and automated patient monitoring.
- Finance – Fraud detection, AI-driven financial advisory services, and automated trading platforms.
- E-commerce – AI chatbots for customer service, recommendation engines, and supply chain optimization.
- Software Development – AI-assisted coding tools and real-time cybersecurity solutions.
According to Tan, AI is no longer a trend but a foundational element of modern startups. “The companies that will thrive are the ones that understand how to integrate AI into their core operations.”
What Sets the 2025 Startup Cohort Apart?
Each YC batch introduces a fresh wave of innovative entrepreneurs. The 2025 Winter Demo Day showcased startups with unique characteristics that distinguish them from previous cohorts.
1. Diverse Founder Backgrounds
Unlike earlier years, where most YC founders had traditional tech and engineering backgrounds, this year’s cohort features a broader mix of professionals. Healthcare, finance, government, and creative industry entrepreneurs are now leading startups, bringing fresh perspectives and unique problem-solving approaches to the tech world.
2. Focus on Sustainable Growth
Startups historically prioritized rapid growth, often at the expense of profitability. However, the 2025 cohort is shifting toward sustainable and profitable business models. Investors are more cautious, and founders recognize the importance of revenue generation from an early stage.
3. International Startups on the Rise
This year, YC has accepted a record number of international startups. Companies from India, Brazil, Nigeria, and Germany are tackling region-specific challenges while competing in the global market. This reflects YC’s commitment to fostering entrepreneurship beyond Silicon Valley.
4. Advancements in Deep Tech and Biotech
While AI-driven startups dominate discussions, deep tech and biotech innovations also make waves. Startups in these sectors are developing cutting-edge solutions in space technology, quantum computing, gene therapy, and sustainable energy. YC’s support enables these companies to navigate the complexities of high-tech innovation.
The Future of Startups and YC’s Role
As market conditions fluctuate and technology advances, YC remains dedicated to equipping startups with the tools to succeed. Tan emphasized that YC continuously adapts its approach to ensure founders stay ahead of emerging industry trends.
Adapting to Market Trends
One of YC’s greatest strengths is its ability to anticipate and respond to market shifts. Whether it’s the rise of remote work, the evolution of decentralized finance (DeFi), or the expansion of sustainable technology, YC ensures startups are positioned to seize emerging opportunities.
Strengthening the Founder Community
YC’s strong founder community remains a key asset. Alums support one another by sharing insights, funding new ventures, and mentoring early-stage entrepreneurs. In 2025, this network will be more active than ever, fostering collaboration and innovation.
YC’s Lasting Impact on the Startup Ecosystem
The 2025 Winter Demo Day reaffirmed Y Combinator’s status as the leading startup accelerator, setting the stage for the next generation of groundbreaking companies. By supporting AI-driven businesses, expanding its international reach, and emphasizing sustainable growth, YC ensures its startups are well-positioned for long-term success.
With AI reshaping industries, international startups gaining prominence, and profound tech innovations accelerating, the future of entrepreneurship is brighter than ever. YC continues to play a vital role in this transformation, nurturing the next wave of visionary companies that will redefine industries and shape the future of technology.
