This overview presents the logistics, funding details, eligibility criteria, incorporation requirements, application policies, and support considerations associated with Y Combinator’s program. It is intended as an informational listing of program details and application logistics, not as an application channel operated by the publisher.
Program Format and Location
• Format: The program runs in person in San Francisco.
• Kickoff: It begins with a three-day, in-person retreat.
• Weekly engagement: The batch includes weekly meetups in San Francisco.
• Remote history: YC was run remotely during Covid, but it has been back in person since 2022.
• In-person effectiveness: YC has found that the program works much better in person.
• Post-program: After the three-month program, founders can operate from anywhere.
• Time commitment: The time commitment is less than most founders expect—a few hours per week if founders participate in all recommended activities.
• Flexibility: All parts of the program are optional; founders are expected to choose how to spend their time to maximize the odds of company success.
• Focus: YC is designed to allow founders to spend several months completely focused on their startup without distraction; many founders report that their three months in YC was the most productive time of their lives.
Selection Process and Application Timing
• Application process: There is an open application process for any startup anywhere in the world; startups can apply online for the next funding cycle.
• Selection approach: YC chooses which startups to fund through the application process.
• Funding cycle: Founders can apply online for the next funding cycle.
• Next batch dates: All relevant dates are available on the program’s dates page.
• Deferring to a later batch: Yes, founders can apply to a later batch; the most common path is students applying for the batch that starts after graduation, which is called Early Decision.
• Actively fundraising now: Founders should apply now and state on the application that they are actively fundraising; if accepted, the investment process begins immediately rather than waiting for the next batch.
Investment Amount and Permitted Use
• Investment size: YC invests $500,000 in each company.
• Permitted use: Founders can use the investment for anything they believe helps the business.
• Typical first use: In most cases, the first use of the funding should be to support founders so they can work full-time on the company, typically by paying themselves a salary.
• Personal obligations: If founders have student loans, a mortgage, or similar obligations, they can use what they pay themselves from the investment to cover those.
• Travel: Founders can also use the investment to cover travel expenses to San Francisco.
• Startups that do not need funding: At least half of the startups funded do not need the money, and the money is only a small part of what YC does.
• Higher prior valuation: A large percentage of each batch has already raised money at a higher valuation than is implied by the YC investment; founders should consider whether joining YC can improve the startup’s outcome by at least 7%, rather than viewing it as a down-round.
Eligibility and Startup Stage
• Early-stage applicants: It would be a mistake to wait to apply; on average, 40% of the companies funded in each batch are just an idea, and most do not have revenue.
• Recommended timing: YC recommends applying as soon as founders have a team and an idea they are excited about.
• Further-along companies: YC also funds companies that are much further along; 7% of recent batches had more than $50,000 in monthly revenue when accepted.
• Larger existing companies: Companies such as Rappi and MessageBird participated when making well over $1 million per year.
• Series A boundary: YC can probably help any startup that has not already raised a Series A round from VCs.
• Already raised funding: Each YC batch has many companies that have already raised over $1 million.
• Solo founders: YC regularly accepts solo founders, though one-person startups are tough and success is more likely with a co-founder.
• Co-founder matching: Founders without a co-founder can use YC Co-founder Matching, a free product to help people find co-founders.
• Non-technical founders: It is important for the founding team to have the skills to build the product themselves rather than outsourcing it; for most businesses, that usually means having a technical co-founder.
• Full-time students or employees: Applicants can apply while studying or working full-time, but accepted founders are expected to commit full-time during and after the batch.
• Fields considered: YC will consider startups in any field, including microbes, fusion reactors, and coffee carts; funded companies are listed in the YC Startup Directory.
• Similar existing YC companies: Having already funded a company doing something similar is not a factor; YC avoids discussing one competing startup’s work with another.
• Repeat applications: Companies can apply more than once; in a typical batch, about half the companies applied multiple times before acceptance. Applicants are asked to submit only one application per batch.
• Introductions: Applicants do not need to know someone at YC; all applications are considered equally, and YC does not rely on introductions the way many investors do.
• Previous accelerator participation: Yes, some companies join YC after doing another accelerator, but YC may expect a higher level of progress.
• Feedback: YC does not provide feedback on application results unless an applicant is invited to interview; interviewed founders receive detailed feedback about why they were or were not selected.
Visa, Incorporation, and Legal Considerations
• Pre-application status: Startups do not need to incorporate, obtain visas, or obtain business licenses before applying; if accepted, YC helps with visas and incorporation.
• US visa holders: In most cases, founders working and living in the US on a visa such as an H-1B can participate in YC and stay in the US.
• Immigration support: YC works with immigration attorneys who have helped hundreds of founders get visas to move to or stay in the US.
• Individualized visa planning: If invited to join YC, founders are connected with an immigration attorney who will develop an individualized immigration plan.
• Incorporation before applying: No, companies do not need to incorporate before applying.
• Non-US incorporation: If a company is already incorporated somewhere other than the United States, Canada, Singapore, or the Cayman Islands, it will need to create a parent company in one of those jurisdictions to participate.
• Legal restructuring: The existing company becomes a subsidiary of the new parent; YC connects founders with lawyers to drive the process, but it requires significant effort.
Application Policies and Logistics
• Multiple ideas: Groups with two ideas should pick their favorite idea and apply with that one; submitting two applications is not recommended.
• Application access: Only the founder who created the application has access to it; other co-founders need to go through that founder to edit.
• Co-founder profile email: If a co-founder has not received an email, founders should confirm the correct address, ensure any existing YC account uses that email, and try removing and re-adding the co-founder to trigger a new email.
• Login mix-ups: If a co-founder is directed to another account page, both users may be on the same computer; opening the link in an incognito browser and signing in with the correct credentials can resolve it.
• Editing after submission: Applications enter review once submitted, so continuous editing is not allowed; for material changes such as a co-founder addition or removal, founders can submit an update through the designated form.
• Submission confirmation: A confirmation email with a copy of the application is sent upon submission; if it is not visible, check spam and verify the email address entered. If still absent, the application likely was not submitted.
• Deadlines, decisions, and interviews: Application deadline, decision timing, and interview questions are answered on the relevant dates page.
• Reusing previous applications: Past applications can be referenced from the account page, but a new application must be filled out each time.
• Recommendations: Recommendations carry over from previous applications; there is no need to ask recommenders to resubmit.
Late Applications
• Definition: Late applications are those submitted after the application deadlines.
• Review effort: YC does its best to continue reading applications submitted after the deadline.
• Current readiness: If ready to do YC, founders should apply now; YC funds many companies that apply late every batch.
• Decision timing: On-time applications have a specific response date, but late applications do not because they are reviewed whenever spare time is available.
• Response timeline: Most late applications receive a decision within a month, but this is not guaranteed and may take longer; YC always responds to everyone who applies.
• Marking as on time: A late application cannot be marked as on time; founders should submit as soon as possible.
Additional Program Details
• Name origin: The name Y Combinator comes from one of the ideas in computer science; it is a program that runs programs, and YC describes itself as a company that helps start companies.
• Operating principles: YC’s operating principles are described in its Founding Principles documentation.
• Startup directory: All funded companies can be viewed in the YC Startup Directory.
• Product publicity: The best way to publicize a product or service within the YC community is to get a few YC startups as happy users and ask them to recommend it; YC also keeps a list of offers for active portfolio companies and manually reviews special deals submitted through the designated form.
• Hiring: YC is hiring, and so are over 500 companies it has funded.
• Hacker News: Questions about Hacker News are answered in the Hacker News FAQ.
• Paxel builder report: A Paxel builder report is completely optional; Paxel analyzes real coding sessions and produces a builder report that gives extra signal about how founders build. If founders link a Paxel account and opt in on the application, the report is considered alongside everything else; if not, the application is evaluated exactly as before. Founders can sign up and upload sessions any time before the application is reviewed.
For startups evaluating participation, Y Combinator combines an in-person San Francisco batch with a standard investment amount, structured application and late-application policies, and support for visa and incorporation matters. Because deadlines, interview dates, and application forms are maintained by Y Combinator, prospective applicants should consult the program’s official dates page and application portal directly for the most current information.
