Y Combinator, sourced from its own materials

#Why YC gets its own module in this course

Y Combinator is the name most people reach for as shorthand for "how startup accelerators work," and the site owner named it specifically as a reference point for this course. It also happens to be one of the very few institutions in this entire course that publishes its actual mechanics — deal terms, application process, batch structure — directly on its own site, in plain language, rather than leaving candidates to reconstruct the process from secondhand blog summaries the way IB and PE recruiting largely have to be. Every figure in this module was checked directly against ycombinator.com itself rather than a third-party summary of it.

#The application and interview mechanics

Applications go through YC's own portal (apply.ycombinator.com). YC states plainly on its own applications page that a promising application earns an interview invitation. [Established] — ycombinator.com's own application page, checked directly. For the most recent batch checked in this research (Fall 2026), the standard application deadline was July 27 at 8pm PT, with decisions for on-time applicants promised by August 28 and interviews held by video conference in August and September; late applications remain open with no guaranteed decision timeline. [Established] for this specific batch's stated dates — treat exact dates as changing batch to batch and re-check ycombinator.com/apply directly for the batch you're actually applying to, rather than relying on this course for a current deadline. YC states that it typically decides the same day as the interview and gives every interviewed candidate detailed feedback on the decision. [Established] — YC's own stated policy.

#Batch structure: four cohorts a year, smaller than they used to be

YC moved from running two cohorts a year to four (Winter, Spring, Summer, and Fall) starting in 2025, a change TechCrunch reported and YC president Garry Tan confirmed publicly. [Established] — Garry Tan's stated rationale, reported directly: with more frequent batches, the timing is more likely to work for a founder ready to apply, and the pace of company formation (Tan specifically cited AI-driven startup formation) justified funding companies faster rather than waiting for a twice-a-year cycle. [Established] Tan also stated publicly that despite the larger number of cohorts, YC intended to fund roughly the same total number of companies per year — meaning each individual batch is smaller than the roughly 400-company peak batches YC ran around Winter 2022, with batches since the four-cohort shift commonly reported in the 140–250 company range. [Directional] for the specific current range, which moves batch to batch; [Established] for Tan's own stated intent behind the change.

A specific Fall 2026 batch YC's own page described runs as a three-day, in-person kickoff in San Francisco followed by regular meetups over the program, with founders assigned a General Partner, meeting weekly, and organized into smaller peer groups for weekly dinners. [Established] — the program's own description on ycombinator.com, though the exact format is subject to change batch to batch; YC states explicitly that its support doesn't end when the three months do, and that it continues helping founders "for the life of their company, and beyond." [Established]

#Acceptance rate — a figure YC's own leadership has stated directly, and one worth being precise about

Unlike almost every acceptance-rate figure elsewhere in this course, YC's acceptance rate has an actual on-the-record source: Garry Tan has stated publicly that YC's acceptance rate runs around 0.8%–1%, and has specifically described the constraint as partner capacity to work closely with each company, not a shortage of promising applicants. [Established] — a direct, attributed statement from YC's own president, reported by named outlets including Crain's New York Business. Application volume and the resulting precise rate move meaningfully batch to batch — the Summer 2025 batch was separately reported as the lowest on record at roughly 0.6% — so treat "about 1%, sometimes lower" as the honest current picture rather than a single fixed number. [Directional] for the specific batch-to-batch figures beyond Tan's own stated range.

#The investment terms, exactly as YC states them

YC's own deal page (ycombinator.com/deal), checked directly for this course, states its standard terms plainly: YC invests $500,000 in every accepted company, split into two SAFEs (Simple Agreement for Future Equity, YC's own instrument, first published by YC itself in 2013 as an alternative to a priced equity round). The first $125,000 is a post-money SAFE that converts to a fixed 7% equity stake. The remaining $375,000 is an uncapped SAFE carrying a Most Favored Nation (MFN) provision — meaning it converts on the same terms as the lowest valuation cap given to any other SAFE investor in the company between the batch start and the company's next priced round, rather than on a cap YC sets itself. [Established] — YC's own current stated terms, confirmed identically on both its /deal and /about pages in this research. In YC's own worked example, at a $15M valuation cap, the $375,000 MFN SAFE converts to approximately 2.5% of the company, putting YC's total stake in a typical outcome in the high single digits of equity for its combined $500,000. [Established] — YC's own illustrative example, not this course's estimate.

Three further terms YC states explicitly and that are frequently mischaracterized in secondhand content: the investment is not contingent on hitting any milestones once a company is accepted; YC charges no fees to companies for participating; and YC retains pro rata rights — the right, not the obligation, to invest further in a company's future funding rounds to maintain its ownership percentage as the company raises more capital. [Established] — all three are YC's own stated terms. YC's standard deal is available only to companies incorporated in the US, Canada, Cayman Islands, or Singapore. [Established]

#What this means read against the rest of this course

YC's own transparency here is the exception, not the rule, across this course's three tracks — which is precisely why this module leans almost entirely on primary, firm-published material rather than the aggregated secondary-source synthesis most of the rest of this course has to rely on. Where YC declines to publish a figure (a precise, current application count; a total combined portfolio valuation), this module has correspondingly declined to assert one on its behalf.

The course closes with an honest comparison of all three tracks — Module 11 — followed by the full sourcing record in Module 12.
