Palo Alto has only one accelerator that most locals would name without thinking: StartX, the Stanford program based in Stanford Research Park. Yet founders who live here apply to programs all over the Bay Area. Y Combinator is a Caltrain ride north in San Francisco. Plug and Play is a short drive south in Sunnyvale. Berkeley SkyDeck sits across the bay. This guide explains how these programs work, what each one says it offers and when to apply.

Terms and dates change often. Every number below comes from the program's own website or another source we checked in October 2026. Confirm the details on the official page before you submit anything. For the people and money that come after an accelerator, see our seed and pre-seed funds guide.

How accelerators work

An accelerator is a short, structured program for a group of early companies that start and finish together. The group is called a cohort or a batch. Most programs follow a similar pattern:

  1. Application. A written form, often with a short founder video. Programs look at the team first, then the idea and any early traction.
  2. Interview. A short conversation with partners, often by video.
  3. Investment. Many accelerators invest a fixed amount in every company in exchange for equity, usually through a SAFE. Some university and nonprofit programs take nothing.
  4. The program. Usually about three months of office hours, group dinners, talks and introductions.
  5. Demo day. Each company pitches to an invited room of investors. This is where many seed rounds start.

An incubator is a looser idea. It typically offers space, equipment and advice for as long as a company needs, without a fixed batch or an end date. Lab incubators for biotech and hardware companies are the most common kind near Palo Alto. If the word SAFE is new to you, our venture capital glossary and term sheet basics explain it.

StartX, the Stanford accelerator

StartX is a nonprofit accelerator and founder community for Stanford students, faculty and alumni. Its website says it takes no equity and charges no fees. That makes it unusual among well-known programs. In return, it is selective. Teams generally need at least one founder with a Stanford connection.

The program runs in cohorts named by season. For the Summer 2026 cohort, StartX held applicant info sessions on campus and online and kept applications open until February 15. Its site also listed a November 1 deadline for StartX Fellows in fall 2026. Future cohort deadlines are posted on the StartX site and announced at its info sessions, which are listed on Luma.

StartX is based in Stanford Research Park. It plans to be the anchor tenant of The Link, a new hub being built with Stanford Research Park that StartX says is set to open in early 2027. The organization publishes its own track record on its homepage. When we checked, it listed 144 companies valued at over $100 million and 29 valued at over $1 billion. It also runs investor demo days three times a year, covered in our tech and startup events guide.

Who should apply

StartX suits founders who already have Stanford ties and want a peer network more than a check. Because it takes no equity, many founders do it alongside another accelerator or a seed round. Read more about the university's other programs in our Stanford entrepreneurship guide.

Y Combinator

Y Combinator, usually shortened to YC, is the best-known accelerator in the world. Paul Graham, Jessica Livingston, Robert Tappan Morris and Trevor Blackwell launched it in March 2005. It began with two programs, one in Cambridge, Massachusetts and one in Mountain View, California. In January 2009 it closed the Cambridge program and centered everything in Silicon Valley, with Mountain View as its home for years. It has since moved its base to San Francisco. Wikipedia counts more than 5,000 companies funded, including Airbnb, Stripe, DoorDash, Dropbox and Instacart.

The deal

YC's site says it invests $500,000 per company. That is split into $125,000 for 7 percent on a post-money SAFE and $375,000 on an uncapped SAFE with a most favored nation clause. Read the current terms on the YC about page before you apply.

Timing

YC now accepts companies in four batches a year. When we checked in late October 2026, applications were open for the Winter 2027 batch, which runs January to March in San Francisco. The on-time deadline was November 2 at 8 p.m. Pacific time. YC said on-time applicants would hear by December 11 and that most interviews would happen by video in November and December. It also allows early decision applications for the spring, summer and fall batches. The batch opens with a three day in-person kickoff and holds weekly meetups in San Francisco. Check the YC apply page for the current calendar.

From Palo Alto, the San Francisco program is a manageable commute. Caltrain runs from Palo Alto station to 4th and King. Our getting around guide covers fares and Clipper.

Plug and Play in Sunnyvale

Plug and Play Tech Center is headquartered in Sunnyvale, about 15 minutes south of Palo Alto by car. Saeed Amidi founded it in 2006. The idea grew out of a downtown Palo Alto building. Amidi's family business bought 165 University Avenue in 1988 and rented space to young companies there, including Logitech, PayPal's predecessor and Danger. Amidi invested early in some of them. Our famous tech addresses tour stops at that building.

Plug and Play works differently from YC. Its programs are built around large corporate partners that want to find startups to work with, grouped by industry. It also invests in startups through its venture arm. CB Insights ranked it the most active startup accelerator in the world from 2020 to 2022, with an average of more than 900 deals a year. For a founder selling to big companies, the main value is introductions. Programs, terms and dates vary by industry track, so check the Plug and Play site for the one that fits.

Alchemist

Alchemist is an accelerator for companies that sell to businesses rather than consumers. Its site describes it as sector agnostic and always building for the enterprise. It backs pre-seed and seed companies. Its site lists check sizes from $60,000 to $1 million. It keeps a desk in San Francisco for founders and has partner programs abroad. Alchemist builds toward a demo day like most accelerators. It does not publish a fixed deadline on its homepage, so watch its site and social accounts for the next intake.

Berkeley SkyDeck

Berkeley SkyDeck is a program of the University of California, Berkeley, at 2150 Shattuck Avenue in downtown Berkeley. Its site says the Berkeley SkyDeck Fund invests $200,000 in each startup in the accelerator and that about 20 startups are chosen every six months. SkyDeck's homepage said applications open in January. SkyDeck also runs Pad-13, an incubator track that requires at least one founder affiliated with the University of California. For a Palo Alto founder, the drive to Berkeley can take an hour or more at rush hour, so plan your weeks around it.

Other programs close to Palo Alto

  • PearX. Pear VC in Menlo Park runs PearX, a 12 week program for very early founders. It is a good fit for student and first-time teams. See our venture capital guide for more on Pear.
  • Page Mill Labs. A 77,300 square foot wet lab incubator at 950 Page Mill Road in Stanford Research Park, aimed at life science startups. It rents lab space and shared equipment rather than running a batch program.
  • Stanford Biodesign. The Stanford Mussallem Center for Biodesign runs a roughly 10 month Innovation Fellowship for people who want to invent medical technology. It says 58 companies have launched from technologies started there.

Choosing a program

The best program depends on what you are missing. If you lack money, the deal terms matter most. If you lack customers, Plug and Play's corporate network or Alchemist's enterprise focus may help more. If you lack a network in the Valley, a large batch like YC's gives you hundreds of peers at once. If you already have Stanford ties, StartX costs you nothing but time.

Ask a few questions before you accept any offer:

  • How much equity does the program take and on what instrument?
  • Does it require you to relocate? For how long?
  • Who are the partners you will actually work with?
  • What happened to the last two batches? Ask alumni directly.
  • Does the demo day draw the investors you need for your sector?

Practice your pitch before the interview. Our guide to pitching Silicon Valley investors covers what partners usually ask.

Tips for founders coming from outside the Bay Area

Good to know

  • Most interviews now happen by video, but in-person programs expect you nearby once the batch starts. Short-term furnished rentals fill up near batch start dates. Compare hotels and long stays near Stanford if you need a base while you look.
  • International founders can set up a travel eSIM before landing so phone verification and maps work from day one.
  • A Palo Alto base puts you within a train ride of San Francisco programs and a short drive of Sunnyvale and Menlo Park.
  • Getting into an accelerator is not the only path. Many local companies raise from angels and seed funds without one.

Frequently asked questions

Does StartX take equity?

No. StartX says it takes no equity and charges no fees. It is a nonprofit community for founders with Stanford ties, such as students, alumni and faculty. In exchange for no cost it is selective, so treat the application seriously.

Is Y Combinator still in Mountain View?

No. Y Combinator ran its Silicon Valley program from Mountain View for years after it closed its Massachusetts program in 2009. It has since moved its base to San Francisco. YC's application page says batches take place in person at its San Francisco campus.

How much does Y Combinator invest?

YC's site says it invests $500,000 per company. That is $125,000 for 7 percent on a post-money SAFE plus $375,000 on an uncapped SAFE with a most favored nation clause. Check the YC site for the current terms before you apply.

When is the next Y Combinator deadline?

When we checked in late October 2026, YC was taking applications for its Winter 2027 batch, which runs January to March in San Francisco. The on-time deadline was November 2 at 8 p.m. Pacific time, with decisions by December 11.

What is the difference between an accelerator and an incubator?

An accelerator runs a fixed-length program for a cohort of startups, usually ending in a demo day. It often invests in exchange for equity. An incubator gives space and support over a longer, open-ended period. Many programs mix the two, so read each one's terms.
