What is Y Combinator?

Y Combinator is the world’s premier startup accelerator, founded in March 2005 by Paul Graham, Jessica Livingston, Robert Tappan Morris, and Trevor Blackwell. Originally operating from Cambridge, Massachusetts and Mountain View, California, YC consolidated operations in Silicon Valley in 2009 before relocating to San Francisco’s Dogpatch neighborhood in 2023.

The accelerator’s model is straightforward but powerful: selected founders receive $500,000 in seed funding ($125,000 for 7% equity plus $375,000 on an uncapped SAFE with MFN provisions) along with intensive mentorship, connections to top investors, and access to an alumni network of over 11,000 founders. Non-profit organizations receive a $100,000 donation instead of equity investment.

Since 2024, Y Combinator has expanded to accept four batches of companies per year (previously two), with each batch typically featuring 250-300 startups. YC startups go through an intensive 11-week program that culminates in Demo Day, where founders pitch to hundreds of leading investors competing to fund the next wave of breakthrough companies.

Y Combinator’s Investment Track Record

The numbers behind Y Combinator’s success are staggering. As of 2025, the accelerator has:

• Invested in 5,000+ companies across all batches
• Generated more than $600 billion in combined valuation
• Facilitated $145 billion in follow-on funding for portfolio companies
• Produced 82 unicorns (companies valued at $1B+)
• Achieved 17 public offerings among alumni companies
• Maintained an 87% survival rate (only 13% of companies have shut down)

The top four YC companies by market capitalization—Airbnb, DoorDash, Coinbase, and Instacart—account for over 84% of the total public market value created by YC alumni. These consumer-focused giants have generated more than $200 billion in market cap, while B2B companies represent approximately $170 billion in private valuations and continue rising.

For sales teams targeting funded startups, Y Combinator companies represent an exceptionally high-value segment. These startups are well-capitalized, growth-focused, and actively seeking solutions to scale their operations.

Y Combinator Funding Trends and Statistics

2024-2025 Batch Characteristics

Recent YC startups reveal clear market trends and investment priorities:

AI Dominance: The Winter 2024 batch featured approximately 66% of companies integrating AI technologies into their solutions. By Spring 2025, over 50% of the 144-company batch was building agentic AI solutions, with 70+ AI companies spanning 18 different categories.

B2B Focus: Consistent with recent years, B2B startups dominate YC batches. The Winter 2024 cohort included 162 B2B companies, reflecting the accelerator’s shift from consumer-focused investments in its early years to enterprise software dominance.

FinTech Resurgence: In 2025, Y Combinator significantly increased fintech investments, participating in 100 fintech funding deals through September—far exceeding the pace of previous years. When examining rounds greater than $5 million, YC participated in 43 fintech deals, up 65.4% compared to all of 2024.

Seed Round Sizes: The median seed round size for YC startups stabilized around $3.1 million in 2025. Healthcare startups consistently raise larger rounds, with a median of $4.6 million reflecting longer development cycles and regulatory requirements. Top-tier YC companies (5-10% of each batch) with $150K-$500K ARR typically raise $2 million at $20-25 million post-money valuations.

Geographic Distribution

While Y Combinator has always welcomed international founders, the program remains predominantly North American:

• United States: 85-90% of startups (primarily San Francisco Bay Area and New York)
• Europe: 5-6% representation
• Asia: 2-3% (including South Asia)
• Latin America: <1%
• Africa: 1-2%
• Remote: Significantly decreased post-COVID-19 to seven-year lows

Interestingly, geographic diversity peaked during Summer 2020-Summer 2021 when remote work was most prevalent, then declined as YC returned to in-person programming in San Francisco.

Top Industries and Sectors in YC Portfolio

Y Combinator’s portfolio spans virtually every major industry, but clear patterns have emerged:

Y Combinator Demo Days and Batches

Y Combinator’s batch system creates natural engagement windows for reaching startup founders:

Current Batch Schedule (2024-Present)

• Winter Batch (W): Applications due October, program runs January-March
• Spring Batch (X): Applications due January, program runs April-June
• Summer Batch (S): Applications due April, program runs July-September
• Fall Batch (F): Applications due July, program runs October-December

Each batch follows a similar structure:

1. Weeks 1-8: Intensive building period with weekly office hours, group sessions, and founder networking
2. Week 9: Preparation for Demo Day presentations
3. Week 10-11: Demo Day events where founders pitch to investors
4. Post-Demo Day: Fundraising period where companies close seed rounds

Demo Day Dynamics

Demo Day represents the culmination of the YC program and creates significant investment activity. Hundreds of top-tier venture capitalists attend (virtually and in-person), often competing aggressively to fund standout companies. Many YC startups announce seed or Series A rounds within weeks of Demo Day.

For sales teams, the post-Demo Day period (typically 2-4 weeks after each batch concludes) represents optimal timing for outreach, as founders have secured funding and are actively building their teams and infrastructure.

How to Identify and Target YC Startups

Finding Recently Funded YC Companies

Several resources help identify and track YC startups for your outreach campaigns:

Official Sources:

• YC Company Directory: Searchable database of all YC-funded companies
• YC Blog: Announces each new batch with company details
• Demo Day listings: Published after each batch

Third-Party Databases:

• YCDB (Y Combinator Database): Comprehensive tracking with filtering by funding, metrics, and batch
• Crunchbase: YC portfolio hub with funding data
• Growth List: Curated database of funded startups including YC alumni

Key Timing Considerations

Understanding YC’s batch schedule creates strategic outreach opportunities:

Optimal Outreach Windows:

1. Weeks 2-4 Post-Demo Day: Companies have closed funding rounds and are actively hiring and building infrastructure
2. Mid-Batch (Week 5-6): Founders are deep in product development and receptive to tools that accelerate progress
3. Pre-Demo Day (Week 8-9): Companies preparing for fundraising may need analytics, presentation tools, or growth solutions

Avoid: The week immediately before and during Demo Day (Week 10-11), when founders are consumed with investor presentations.

Segmentation Strategies

Not all YC startups represent equal opportunities. Consider segmenting by:

Funding Stage:

• Post-Demo Day seed stage (most recent batch)
• Series A (6-18 months post-batch)
• Series B and beyond (established growth companies)

Industry Vertical:

• AI startups
• FinTech startups
• Healthcare startups
• B2B SaaS

Geography:

• San Francisco startups
• NYC startups
• Boston startups

Employee Count:

• Early stage (2-10 employees): Focus on foundational infrastructure
• Growth stage (11-50 employees): Scaling operations and processes
• Expansion stage (50+ employees): Enterprise solutions and optimization

Reaching Y Combinator Founders: Best Practices

Understanding the YC Founder Mindset

YC startups operate according to several core principles that shape how alumni companies make decisions:

“Do Things That Don’t Scale”: Early-stage YC founders prioritize rapid iteration and direct user engagement over premature optimization.

“Make Something People Want”: Product-market fit drives decisions. Solutions that clearly solve pressing problems receive immediate attention.

“Talk to Users”: YC founders are trained to constantly engage with customers and incorporate feedback.

These principles inform effective outreach strategies. YC founders respond to:

• Specific value propositions tied to their current growth stage
• Data and case studies from similar companies
• Personalized messaging showing understanding of their product and market
• Efficient communication that respects their time

Email Outreach to YC Startups

When crafting cold emails to YC founders:

Do:

• Reference their batch (e.g., “Congrats on completing W24”)
• Mention specific product features or recent milestones
• Lead with concrete value (“Help you reduce infrastructure costs by 40%”)
• Include relevant case studies from similar YC companies
• Keep messages under 150 words
• Use proper email warm-up to ensure deliverability

Don’t:

• Generic batch emails to entire cohorts
• Overly long pitches requiring significant time investment
• Pushy follow-ups during Demo Day week
• Assumptions about their needs without research

Timing Best Practices:

Review our guide on cold email follow-up timing for optimal sequences when reaching YC founders. Generally:

• Initial outreach: 2-3 weeks post-Demo Day
• First follow-up: 4-5 days after initial email
• Second follow-up: 1 week after first follow-up
• Final follow-up: 2 weeks after second (reference specific trigger event)

Leveraging the YC Network

The Y Combinator alumni network is famously tight-knit and actively helps fellow founders. Strategies to leverage this:

Warm Introductions: If you have existing relationships with YC alumni, ask for introductions to relevant companies in recent batches. YC founders frequently make intros within the network.

YC-Specific Value Props: Many services offer special pricing or terms for YC companies. If you can provide startup-friendly terms, lead with this: “Special pricing for YC W24 batch companies.”

Alumni References: Case studies featuring YC companies carry significant weight. “We helped Segment (YC S11) achieve X outcome” immediately establishes credibility.

Multi-Channel Approach

While email remains primary for B2B outreach, consider:

LinkedIn: Many YC founders are active on LinkedIn, particularly for hiring and networking. Thoughtful connection requests with personalized notes can work well.

Twitter/X: YC has a strong Twitter presence. Engaging meaningfully with founder content (not spam) can build awareness.

Demo Day Events: Some investors and partners can attend YC events, creating in-person networking opportunities.

YC Work at a Startup: Companies hire through YC’s job board, which also serves as a discovery tool for service providers.

Investment Trends: What YC Backs in 2025-2026

Agentic AI Takes Center Stage

The most dramatic shift in Y Combinator’s portfolio is the explosion of agentic AI companies. Unlike traditional AI applications that assist human decision-making, agentic AI systems autonomously perform tasks and achieve goals.

YC’s Spring 2025 batch dedicated over 50% of slots to agentic AI across categories including:

• Business Operations: AI agents that handle administrative tasks, scheduling, and workflow automation
• Customer Service: Autonomous support systems that resolve issues without human intervention
• Sales & Marketing: AI-powered outreach, qualification, and nurturing systems
• Software Development: AI coding assistants that write, review, and deploy code
• Data Analysis: Systems that automatically analyze data and generate insights
• Creative Production: AI agents for content creation, design, and multimedia production

This focus aligns with broader market trends. Companies building AI infrastructure and applications consistently raise larger rounds at premium valuations compared to traditional software.

B2B Infrastructure Continues Dominance

Y Combinator has evolved from a consumer-focused accelerator to primarily backing B2B infrastructure companies. Recent batches show 60-65% of companies serve business customers rather than consumers.

This shift reflects several factors:

• Faster path to revenue: B2B companies can charge from day one
• More predictable growth: Subscription models provide clearer metrics
• Higher valuations: Enterprise software commands premium multiples
• Less marketing spend: Targeted B2B sales are more capital-efficient than consumer acquisition

For sales teams, this trend creates opportunities, as YC companies increasingly resemble traditional enterprise buyers with formal procurement processes and budget allocation.

Vertical SaaS and Industry-Specific Solutions

YC is backing more startups building specialized solutions for specific industries rather than horizontal platforms. Recent examples include:

• Healthcare operations platforms for specific provider types
• Construction management software for contractors
• Legal tech solutions for law firms and corporate legal teams
• Manufacturing execution systems for factories
• Agriculture technology for farm operations

These vertical solutions often achieve faster product-market fit and face less competition than horizontal tools.

Climate Tech and Sustainability

Climate technology has emerged as a significant YC investment area, with startups addressing:

• Carbon capture and removal: Technologies to extract CO2 from atmosphere
• Renewable energy: Solar, wind, and alternative energy solutions
• Sustainable materials: Alternatives to plastics and traditional manufacturing
• Climate data and analytics: Tools for tracking and reducing emissions
• Energy efficiency: Solutions reducing power consumption

Notable climate-focused YC companies include Helion Energy (W14) working on fusion power and Carbon Robotics building autonomous farming equipment.

Web3 and Decentralized Technologies

Despite crypto market volatility, Y Combinator continues backing blockchain and Web3 infrastructure companies, particularly:

• Developer tools for building decentralized applications
• Infrastructure protocols for blockchain networks
• DeFi platforms for decentralized finance
• NFT marketplaces and creator tools (OpenSea from S17)
• DAO tooling for decentralized organizations

These companies typically target technical users and infrastructure needs rather than consumer speculation.

Comparing Y Combinator to Other Accelerators

Y Combinator vs. Sequoia Arc

Sequoia Capital’s Arc accelerator (launched 2023) represents the most direct competition to YC. Key differences:

Sequoia Arc:

• Cohort-based but doesn’t take equity
• Focus on Series A-ready companies ($1M+ ARR)
• Shorter 8-week program
• More selective (30-40 companies per batch)
• Stronger immediate fundraising focus

Y Combinator:

• Takes 7% equity stake
• Accepts pre-revenue and early-stage companies
• 11-week program with longer-term support
• Larger batches (250-300 companies)
• Stronger alumni network and brand recognition

YC Portfolio Performance

Data shows YC companies demonstrate exceptional durability compared to typical startups:

• 87% survival rate vs. roughly 50% for non-accelerated startups after 5 years
• Batch W15 (10 years old) still has over 50% of companies actively operating
• 17 public offerings from 5,000+ companies (0.34% IPO rate)
• 82 unicorns achieved (1.6% unicorn rate)

The W15 batch statistic is particularly telling—after a full decade, more than half the companies still operate, suggesting YC’s selection and support significantly improves startup longevity.

How to Use YC Data for Prospecting

Building Targeted Lists

When building startup lead lists, Y Combinator companies offer several advantages:

Data Quality: YC maintains comprehensive company profiles including:

• Founding team and contact information
• Product descriptions and target markets

• Product launches (+3 days)
• Major hires (CTO, VP Sales) (+1 week)

Y Combinator Success Factors

Selection Process and Acceptance Rates

Y Combinator receives approximately 25,000-30,000 applications per batch but accepts only 250-300 companies, creating acceptance rates under 1%. This extreme selectivity ensures only the most promising founders join the program.

What YC Looks For:

Exceptional Founders: YC emphasizes team quality over initial product. Ideal founders demonstrate:

• Deep domain expertise in their target market
• Technical ability to build rapidly
• Resilience and adaptability
• Clear communication skills
• Complementary co-founder relationships

Large Markets: YC prefers “big ideas” targeting markets with potential for $1B+ outcomes. Small markets with limited expansion potential rarely receive funding.

Early Traction: While pre-revenue companies can get accepted, demonstrating user interest, revenue, or rapid growth significantly improves chances.

Novel Insights: Successful applications often articulate non-obvious insights about market problems or customer behaviors that others miss.

The YC Advantage

Several factors explain why YC companies outperform typical startups:

Intensive Support: The 11-week program provides:

• Weekly group office hours with partners
• 1:1 sessions with experienced startup operators
• Workshops on critical topics (fundraising, hiring, sales)
• Peer learning from 250+ fellow founders

Investor Access: Demo Day connections lead to:

• Immediate fundraising conversations with top VCs
• Higher valuations due to competitive investor interest
• Faster closes due to standardized deal terms
• Follow-on funding from YC Continuity (now discontinued) and alumni network

Alumni Network: The YC community provides:

• Introductions to potential customers
• Hiring referrals for key positions
• Technical advice from experienced founders
• Emotional support during difficult periods

Brand Signal: The YC badge conveys quality to:

• Investors (easier fundraising)
• Customers (faster enterprise sales)
• Employees (top talent recruitment)
• Press (media coverage and visibility)

Why Some YC Startups Fail

Despite advantages, roughly 13% of YC companies eventually shut down. Common failure patterns include:

Market Timing: Building too early for market readiness or too late against established competitors

Team Conflicts: Co-founder disputes or inability to attract necessary talent

Pivot Failures: Attempting too many pivots without gaining traction

Competitive Pressure: Funded competitors with more resources winning the market

Execution Issues: Inability to build product, achieve product-market fit, or scale operations

Interestingly, YC companies fail at much lower rates than typical startups (13% vs. ~50% after 5 years), validating the program’s impact.
