Breaking down Y Combinator's $500,000 standard deal
A breakdown of the two-part check, equity dilution, corporate flip requirements, and pro rata rights.
Y Combinator commits $500,000 to every business admitted into its batch [1]. The funding structure combines an upfront equity stake with a flexible instrument tied to subsequent fundraising [1]. Unlike some competing accelerator programs, the organization charges no participation fees [1].
Y Combinator standard deal structure
The accelerator's headline investment of $500,000 consists of two distinct components [1]. The first check is for $125,000, which purchases a fixed 7% equity stake in the startup [1]. The remaining $375,000 check arrives on an uncapped Most Favored Nation (MFN) Simple Agreement for Future Equity (SAFE) [1].
This two-check model separates the guaranteed base ownership from future financing performance [1]. Funding begins immediately upon acceptance, without waiting for the batch cycle to open or requiring milestones [1].
Mechanics of the uncapped MFN SAFE
The second portion of the investment—$375,000—carries no valuation cap on day one [1]. Instead, it uses an MFN provision that matches the best terms granted to future SAFE investors [1].
When a company closes its next financing round, this instrument takes on the terms of that round [1]. For instance, if the subsequent SAFE round closes at a $15 million post-money valuation cap, the $375,000 SAFE converts into a 2.5% share of the company ($375,000 divided by $15,000,000) [1].
Accelerator fee comparison
| Accelerator Component | Y Combinator Terms |
| --- | --- |
| Total funding | $500,000 [1] |
| Fixed equity check | $125,000 for 7% [1] |
| Flexible check | $375,000 uncapped MFN SAFE [1] |
| Program fees | None charged [1] |
| Follow-on rights | Pro rata participation rights [1] |
Y Combinator does not deduct program costs from its check [1]. While other startup programs deduct advisory or participation charges from their funding, YC provides its investment without charging fees to participating companies [1].
Ongoing investor rights
The standard contract includes pro rata participation rights [1]. This stipulation gives Y Combinator the legal right to purchase additional equity in later financing rounds in order to maintain its ownership stake [1]. The organization notes that it frequently exercises these participation rights to inject millions of dollars into subsequent rounds as companies mature [1].
Qualifying corporate jurisdictions
Y Combinator restricts its direct investments to corporations chartered in four jurisdictions: the United States, Canada, the Cayman Islands, and Singapore [1].
Startups formed elsewhere must undergo a corporate flip to establish a parent holding company inside one of those four approved jurisdictions [1]. The foreign operating entity generally shifts into a wholly owned subsidiary of the new parent entity [1]. Intellectual property may be held either at the parent or subsidiary level based on founder preference [1]. For teams that have not yet incorporated, the program introduces legal counsel upon acceptance to complete the formation [1].
