A $1 million offer can mean $400,000 today. A remote accelerator can still mean three trips.
South Park Commons splits its commitment across an upfront investment and a future round. Techstars Anywhere includes three offsites. Those details can change your shortlist faster than a famous alumni logo.
This guide puts 25 US-accessible accelerators and founder programs in one directory: where you go, what you get, what it costs, and when to apply. It also examines the fundraising and billion-dollar-company statistics founders use to judge them.
Checked September 25, 2026. Start with the master list, narrow it to three candidates, then use the outcome questions below before committing.
Startup accelerator master list: 25 programs at a glance
The directory includes equity accelerators, residencies, free programs and corporate innovation tracks. The program type is labeled because a cofounder residency and a customer-pilot program solve different problems. This is a curated US-focused selection, not a ranking or an exhaustive global list.

Scroll inside the directory for all 25 programs. On mobile, each program becomes a comparison card. All records are included in the download.
How to read the table: “Dated intake” has a verified upcoming deadline. “Rolling” describes an explicitly ongoing application process. “Confirm intake” means a program is verified but its next window needs checking. “Closed / past window” is a watchlist, not an invitation to apply now. Times are included only when published.
Acceptance rates: the three starred figures are general operator-reported claims, not comparable cohort-level rates. The reviewed pages do not identify a common admissions year or application denominator. “Not verified” means we could not establish a rate from the linked primary sources; it does not mean zero.
Which accelerator should you shortlist?
Need a dated application window? PearX closes October 4; StartX’s Stanford-eligible route closes October 11; YC and ERA close November 2; Techstars Anywhere closes November 18. All are 2026 deadlines for the intakes described above. StartX does not state a timezone on the reviewed application page—confirm it rather than assume Pacific.
Cannot relocate? Forum permits remote participation. Techstars Anywhere includes three trips. StartX offers a virtual option with four required in-person days, subject to its Stanford affiliation rules. AI House requires at least a month in Seattle. These commitments are materially different; “hybrid” alone is not enough information.
Still choosing the idea or cofounder? Look at founder-formation programs such as Antler, Entrepreneurs First and SPC’s next fellowship window. Ask how investment decisions work after admission: a place in a residency does not necessarily mean a funded company.
Building with AI or deep technology? AI House is an applied-AI incubator; HAX and SOSV NY & SF serve pre-seed deep-tech companies. Google US is aimed at technical teams around Seed–Series A. Choose based on the actual technical and commercial support you need, not the presence of “AI” in the description.
Already have 20–100 employees? Many entries are built for much earlier companies. Google US, a relevant MassChallenge track or a Plug and Play corporate program may be worth investigating if their criteria fit. An idea-stage residency is unlikely to solve a mature team’s sales or operational bottleneck. These are editorial matches to the published criteria, not endorsements.
What are your chances of raising a seed round?
There is no defensible single percentage for the 25 programs in this directory. Two published figures are useful starting points—but they measure different things.
Operator-reported. The public claim does not specify cohort years, sample size or a fixed follow-up window.
PearX program page ↗Operator-reported. The public claim does not identify the batch or its size; “additional funding” is not necessarily a seed round.
Antler US program page ↗Neither figure establishes that joining caused the funding outcome. Programs select founders; founders arrive with different traction, networks and financing histories. The numbers also describe admitted companies, not everyone who applies.
The useful next step is to ask for a comparable number:
Of all companies admitted to your 2023 and 2024 cohorts, how many closed their first external institutional seed round within 12 months? Exclude your own investment, and include companies that shut down.
That question pins down the denominator, milestone and clock. Ask for the count as well as the percentage, and a few founders you can speak with—including one who did not raise.
Which accelerators have produced unicorns?
YC and Techstars publish striking billion-dollar-company counts. They are evidence of historical portfolio outcomes, but their definitions are too different to turn into a league table.
| Operator | Published claim, checked September 25, 2026 | What it actually tells you |
|---|---|---|
| Y Combinator | More than 100 companies valued above $1 billion; more than 5,000 companies funded since 2005 | A cumulative alumni milestone across many years. It is not a current cohort’s probability of becoming a unicorn. |
| Techstars | 29 billion-dollar companies in its portfolio registry | The registry includes accelerator companies and Seed Fund investments, with public and acquired companies as well as private ones. This is not 29 Techstars Anywhere graduates. |
Do not divide these headline counts by today’s total portfolio and call the result your odds. Older companies have had longer to grow; the definitions and populations differ. Use the alumni list to find companies with a similar customer, business model or technical problem, then investigate what the program actually contributed.
Read the whole accelerator deal
The most useful funding comparison has three columns: money now, conditions later, and total ownership cost.
| Program | What the headline can hide | What to check |
|---|---|---|
| YC | $500K is split between $125K for 7% and a $375K uncapped MFN SAFE | The SAFE creates additional equity on conversion; the full check is not simply for 7% |
| SPC Founder Fellowship | $1M commitment: $400K upfront for 7%, then $600K in the next external round | Timing and terms of the later investment |
| a16z speedrun | $500K for 10% upfront; another $500K in the next round within 18 months | The future round condition and additional dilution |
| AI House | Up to $600K through a capped SAFE, plus 7% common stock for incubation | Both components, funding milestones and actual cash available at entry |
| Berkeley SkyDeck | $210K for 7.25%, plus a $7.5K program fee | Net cash, attendance costs and follow-on participation rights |
A SAFE is an agreement that can convert into equity later. MFN means “most favored nation”: later financing terms can affect the instrument. Eventual ownership depends on the agreements and financing, not just the first percentage shown on a website.
Put travel, relocation, program fees and founder time alongside the offer. Keep cloud credits separate from cash. Credits for a service you would not otherwise buy do not extend payroll runway.
Our verdict: apply for the bottleneck
Build a three-program shortlist around what must change in the next 90 days. Then eliminate anything that fails the stage, attendance or deal test.
Find a cofounder, win initial customers, solve a technical problem or prepare a fundraise.
Check eligibility, founder time, relocation and every required trip.
Look for relevant alumni and defined outcomes. Ask for the full offer in writing.
For immediate applications, start with the five dated intakes in the directory. For everything else, verify the next window before preparing a full application. Use the shortlist worksheet to record your three candidates and the questions each must answer.
A program earns its place on your shortlist when you can explain what it will help you do—and why that benefit is worth its cost.
Sources and maintenance
Each directory row links to the operator’s program, application or terms pages; Plug and Play’s row uses its own March 2026 press release. Outcome claims link directly to their sources. Research checked September 25, 2026; applications, terms and program names can change. Unknowns are labeled rather than filled from third-party roundups.
We include both widely recognized generalist programs and specialist or equity-free alternatives with US relevance and identifiable primary documentation. Network entries are labeled: the Oklahoma City offer does not represent all gener8tor programs, and Techstars Anywhere dates do not apply to the whole Techstars network. SOSV NY & SF are one entry covering the former IndieBio programs. This directory does not attempt to count every local cohort separately.
