Y Combinator's first deal was a $6,000-per-founder stipend

The record

Y Combinator's own 2005 recruitment page, preserved by the Internet Archive, describes what it called the Summer Founders Program: 'we're not going to give each one much more than you'll need for living expenses,' estimated at 'about $6000 per person,' with the note that 'yes answers will include the valuation at which we're willing to invest,' ordinarily 'in the low to mid hundreds of thousands.' Applications closed 26 March 2005. Co-founder Paul Graham's later essay, How Y Combinator Started, dates the decision to found the firm to 11 March 2005 and states that 'YC started with $200k,' $100,000 from Graham and $50,000 each from Robert Morris and Trevor Blackwell.

What the sources establish

The two Graham essays and the archived program page describe a single, small, deliberately synchronous batch, not yet the year-round, high-volume model YC later became. A second Graham essay, Early Photos of Y Combinator, dates the interview weekend to 8 and 9 April 2005 and the first batch's group photograph to 16 August 2005. None of these documents claims the model was expected to succeed at the time: Graham writes that 'we never expected to make any money from that first batch,' describing the money invested as 'a combination of an educational expense and a charitable donation.'

Scope and revision

The 2005 figures describe a program aimed at undergraduates with low opportunity cost, sized to living expenses rather than to a company's runway; the 'low to mid hundreds of thousands' valuation language is a range, not a fixed number, and the page does not disclose how many groups applied or were funded. Comparing 2005 to today requires naming both sides: YC's current standard deal, as retrieved on 16 September 2026, is $500,000 total, split between a $125,000 post-money SAFE for 7 percent of the company and a $375,000 uncapped SAFE carrying a most-favored-nation provision, an instrument that did not exist in 2005 and was not introduced by YC until 2013.

The decision in front of you

This is an editorial observation, not a benchmark to negotiate against. The distance between a $6,000-per-founder stipend in 2005 and a $500,000 standardized instrument in 2026 is not a single continuous inflation figure; the funding instrument, the accelerator's own scale, and the startup-cost environment all changed in between.

• Is a cited YC deal figure from 2005, from the 2013 SAFE introduction, or from the current page?
• Does the source distinguish the accelerator's own investment from any later round the company raised?
• What does 'the YC deal' assume about a company's stage that may not match yours?

Y Combinator's founders did not expect the first Summer Founders Program to work, by their own later account, and they priced it accordingly: enough to live on, for a stake described only as a range. The specificity of today's terms is a twenty-year-old company's earned confidence, not a feature of the original design.
