South Park Commons vs Entrepreneur First (2026): time to explore, or 12 weeks to form a team

Side by side

Every row is explained below with its source. We read both programmes' own pages on 12 November 2026.

The short answer

South Park Commons (SPC) and Entrepreneurs First (EF, usually searched as "Entrepreneur First") both take people before they have a company. That is where the likeness ends.

SPC is built around a stage it calls "-1 to 0": deciding what you want to spend the next five to ten years building. It gives technologists a place to do that among peers, without a deadline to pair up. Its Founder Fellowship adds a short, structured bootcamp for people who already know they want to start a venture-scale company.

EF is built around one hard step: turning individuals into founding teams. You arrive alone, meet the rest of the cohort, pair up, test ideas and re-pair if it doesn't work, all inside 12 weeks. The teams EF backs then move to San Francisco.

So, broadly: if you are still deciding what to build and want to do it among other builders, SPC fits. If you know you want to start a company now, want help finding a cofounder in a structured way, and are early in your career, EF fits.

What South Park Commons is

SPC's homepage calls it "a home for the most talented founders and technologists exploring what's next" and says it "helps you go from -1 to 0". Its Our Story page explains the term: "-1 to 0" is "the stage when you figure out what you want to dedicate the next 5-10 years of your life to building." SPC began in 2016 in San Francisco and today has spaces in San Francisco, New York and Bengaluru.

There are two ways in:

• Member Residency. Six months of "ideating, validating new areas, finding collaborators", in SPC's words. It's for technologists who aren't ready to raise money and "may or may not know" that they want to start a company. SPC's FAQ says it charges no fees or dues, and its India page says you don't have to start a company at the end. Admission is rolling.
• Founder Fellowship. For founders "who know they want to start a venture-scale company and are ready for early funding". It runs twice a year, in spring and fall cohorts. Fellows spend an 8-week bootcamp in person in small cohorts, then move into a Fellow Residency with no fixed end date.

On a page about its model, SPC says "We are not a traditional accelerator." The Fellowship is the part that looks most like one, and many members, SPC says, start in the residency and move into the Fellowship later.

What Entrepreneurs First is

EF's homepage says "We turn exceptional individuals into funded founders." It looks for people who have "continuously outperformed their peer group", have "built products, organizations or startups in the past", and have "the ambition to build a company in the U.S."

Its programmes on the application hub today:

• London Program: from April 2027. Twelve weeks in London, then the last three months in San Francisco.
• Bangalore Program: from February 2027. Apply by 4 December 2026 to be considered in the second of four selection rounds. The listing says you move to San Francisco after 14 weeks; the Bangalore FAQ says FORM is 12.
• The Bridge Residency: an 8-week programme in San Francisco for young Europeans, starting February or April 2027.
• Funding and Fellowships (US): three months in San Francisco, reviewed on a rolling basis.
• XF2: a London programme for people with seven or more years of experience who have founded a startup or been key to one at its start.
• EF Start: a 7-day remote challenge, whose top performers are considered for the US fellowships.

The core programme has two halves. FORM is 12 weeks in your hub city, where teams form. LAUNCH is 12 weeks in San Francisco for the teams that pass EF's Investment Committee.

The "-1 to 0" stage vs building a team from individuals

This is the real difference between the two, and it's why the question "SPC or EF?" has a clear answer for most people.

SPC is about the decision before the company. The residency gives you six months to test ideas, meet people and decide whether a company is even your next step. About 30% of members do research or other work outside the startup track, according to SPC's FAQ. Finding a cofounder can happen along the way, and SPC says earlier fellows have found cofounders in its community, but nothing in the model requires it.

EF is about the team. EF assesses "all applicants as individuals, before they have a business, cofounder or an idea", then makes forming a team the main event. Its homepage lists access to a pool of screened cofounders and guidance on pairing and testing potential partners. The point of FORM is to leave with a cofounder and a company.

If your problem is "I don't know what to build", SPC was designed for that. If your problem is "I want to start a company and I don't have a cofounder", EF was designed for that.

How South Park Commons works, step by step

Using the Founder Fellowship, where SPC publishes the most detail:

1. Apply when the window is open. The Fellowship takes applications twice a year. Fall 2026 applications are closed; SPC's apply page says Spring 2027 applications will open "later this year". For Spring 2026 the deadline was 1 February, with the bootcamp from late March to late May. 2. Show your work, not a pitch. The application asks for the project or achievement you're most proud of, with a link, and two or three artifacts of high-quality work with a short explanation of each. 3. Interview. SPC says it aims to make decisions within a month. For Fall 2026, applicants heard about interview invitations by 30 August. 4. Kickoff. The Fall 2026 cohort started with a week at a private retreat in Northern California and at the San Francisco office. 5. Bootcamp, 8 weeks in person. Fellows work from an SPC office in San Francisco, New York or Bangalore. Partners run working sessions several times a week on customer discovery, product, storytelling and pitching. The Fall 2026 bootcamp runs from late September to late November. 6. Fellow Residency. After the bootcamp there is no fixed end date. Teams can relocate, though SPC encourages staying in a city with an SPC space.

The Member Residency is simpler: you apply any time, SPC usually replies within one to three weeks, and if there's interest it invites you to interview.

How Entrepreneurs First works, step by step

1. Pick one programme in one city. EF asks you to apply to one at a time. 2. Apply as yourself. You need neither an idea nor a cofounder. If you already have one, say so and ask them to apply separately. 3. Meet the Talent Investing team. Applications are reviewed on a rolling basis. Dylan Castillo, who joined EF's Berlin cohort in 2022, wrote that interviews ranged from one to three. 4. Relocate. EF's London FAQ says founders who pass selection "relocate to join us from all over the world". 5. Kick Off Summit. A residential weekend before the programme starts. 6. FORM, 12 weeks. You meet the cohort, pair up, test ideas, and split and try again if a pairing doesn't work. Each founder works with a Talent Investor. 7. Investment Committee, then LAUNCH. Teams EF backs move to San Francisco for the final 12 weeks, which end with a Demo Day there.

Getting in: what each one looks for

South Park Commons

SPC calls itself "a highly selective community" and doesn't publish an acceptance rate. For a sense of scale, SPC's blog said nearly 1,000 founders from more than 20 countries applied to the first Fellowship in 2021, and 16 fellows across 10 teams were chosen.

A 2022 post on SPC's blog describes what it looks for as "velocity" and "acceleration". Velocity is what you have already done: building prototypes, leading teams or communities, deep knowledge of a field. Acceleration is where you're heading: risk tolerance, curiosity, emotional intelligence and ambition. The post says strong members can be high on either, or both.

Most members are technical, according to the FAQ, with exceptions. For the Fellowship, the only strict requirement the page states is "the ambition to build at the frontier". You don't need an idea, but "you do need to show us how you generate ideas."

Entrepreneurs First

EF's FAQ says its programmes are "most valuable for people in the early stages of their career" with exceptional results compared with their peers. Most participants have a technical background; EF takes a small number of non-technical people who show solid technical understanding. With seven or more years of experience and a startup behind you, EF points you to XF2 instead.

EF doesn't assess your idea at all. It assesses you. Alexander Smirnov, who joined EF's London cohort in 2024, described a cohort of about 60 people and said being among "people of your age doing the same thing" was a large part of the value.

What applicants actually had

People searching this comparison often want to know what got others in. First-person accounts help more than any guide:

• Nadia Eldeib, a member of SPC's first Fellowship cohort in 2021, wrote that she was a product manager at Lyft, had no startup idea when asked, applied after the deadline with a short video, and was interviewed on why she wanted to be a founder and why now. She met her cofounder at SPC after joining. She also notes that the 2021 Fellowship was fully remote, unlike today's in-person bootcamp.
• Castillo (EF Berlin, 2022) joined without an idea or a cofounder, which is how EF is designed. He tried three teams during FORM.

Both say the same thing in different ways: neither programme expects you to arrive with a company. SPC wants evidence that you build and think about ideas. EF wants evidence that you outperform.

Time, place and commitment

How long each one lasts

Where you have to be

SPC: members must be in San Francisco, New York or Bangalore and are "expected to come into SPC throughout the week". Fellows work in person from one of the three offices during the bootcamp, and SPC encourages them to stay in one of those cities afterwards. SPC says it "cannot directly sponsor visas" but will discuss individual circumstances.

EF: you move to London or Bangalore for FORM, and if EF backs your team, you move again to San Francisco for LAUNCH. EF doesn't provide visas but says it can often help you apply, and it offers visa assistance and relocation support for the move to San Francisco.

Full-time or not

Both expect your full attention. SPC's FAQ says membership generally requires a full-time commitment, with occasional exceptions, and its 2024 Fellowship page said all team members had to be available full-time by the start. EF is full-time and in person throughout.

Neither works as a side project while you keep your job.

Cohort or community

EF runs as a cohort: everyone starts together, forms teams on the same clock and reaches the Investment Committee at the same time. Castillo counted 49 teams formed across his Berlin cohort, with 13 presenting to the committee.

SPC runs as a community with a cohort inside it. Residency members join on a rolling basis and overlap with each other; fellows go through the bootcamp together in small groups. SPC's 2024 Fellowship page said it had one partner for every two companies.

Solo founders and existing teams

At SPC, solo applicants to the Fellowship are welcome, with "a strong bias for applicants who can build and prototype". SPC says it can help a solo fellow search for a cofounder. Founding teams applying for funding can send one application; for the residency, each cofounder applies separately and notes the other in the application.

At EF, everyone applies alone, even existing cofounders. The programme assumes you'll form a team inside it, and its structure is built for that: you pair, you test, you re-pair.

If you are a solo technical builder, both will take you. The difference is what happens next: SPC lets you stay solo and keep building, while EF expects you to find someone within FORM.

What happens if you don't find a cofounder

At SPC, there's no deadline to pair up. A solo fellow can carry on solo, and a resident can leave after six months without starting a company at all.

At EF, FORM has a clock. EF's FAQ doesn't say what happens to people who end it without a team. Castillo wrote that in his 2022 Berlin cohort, anyone not on a team after the first eight weeks had to leave the programme. Smirnov wrote that you can bring in a cofounder from outside, who goes through the same interviews. EF's FAQ also mentions internal hiring: you can join another EF startup as an early hire.

That is the trade. EF's clock makes people decide, and some leave without a partner. SPC's lack of one gives you time, and you may also leave without a partner.

What participants say

• Eldeib (SPC Fellowship, 2021) describes the pre-idea stage as one that "can be incredibly tough", especially for solo founders, and advises applicants to share openly rather than pitch.
• Castillo (EF Berlin, 2022) liked the people and the push to talk to customers, disliked the number of meetings and the sense of being graded, and said he would "Definitely" do it again.
• Smirnov (EF London, 2024) called the programme "100% worth the time", especially for people without startup-minded friends or a clear idea, while criticising public scoring of teams.

These are single accounts from single cohorts. Ask each programme what the cohort you would join looks like.

Who each one fits

South Park Commons fits you if:

• you're technical, or a domain expert, and still deciding what to build;
• you want months among other builders, not a fixed team-forming deadline;
• you can work from San Francisco, New York or Bengaluru;
• you're comfortable starting solo and finding a cofounder later, or not at all.

Entrepreneurs First fits you if:

• you're early in your career, with results that stand out against your peers;
• you know you want to start a company now and want help finding a cofounder;
• you can move to London or Bangalore for 12 weeks, then to San Francisco;
• you want to build a US company from the start.

Neither fits yet if you can't leave your job or move to one of their cities, or you'd rather choose a cofounder on more than a few weeks in the same office.

Foundinity: find your cofounder before a cohort starts

Both programmes leave you to meet the right person in one room. At SPC you may meet them along the way; at EF you have 12 weeks. Foundinity lets you start the search now, without quitting or moving.

You state what you need in a cofounder, and answer an assessment about how you work: commitment, working style, ambition, personality, goals, values, alongside your skills and interests. A multi-trait algorithm built on established psychological compatibility models ranks the people you see, so you start with compatible people, not hundreds of random profiles. Skills tell you who can do the job. The rest tells you who you can actually build with for years.

Every match shows where the two of you align and where you differ, so questions like "would you move to San Francisco?" or "do you want to explore for six months first?" come up on the first call. A 10-day clock starts on each match, you have a limited number of messages until you book the intro call, and you book that call in the app. Set your status to exploring and only compatible members can see your profile. It's free to get started; Plus is $5 a week or $15 a month.

Once you've found someone and tried working together on a small project, you can apply to the SPC Fellowship as a team, or to EF together (EF asks each of you to apply). Our guides to questions to ask a potential cofounder and a cofounder trial project cover those first weeks.

Which should you choose?

Choose South Park Commons if you're a builder who wants time to decide what's worth the next five to ten years, among peers, in San Francisco, New York or Bengaluru. Pick the residency if you're not sure a company is your next step, and the Fellowship if you are.

Choose Entrepreneurs First if you're early in your career, want to start a company now, want a structured way to find a cofounder, and are happy to relocate twice.

Choose neither yet if you can't leave your job or move. Find a cofounder on Foundinity, work on something small together, and apply as a team when you're ready.

FAQ

Is South Park Commons better than Entrepreneur First?

Neither is better for everyone. SPC suits technologists who want time to decide what to build. EF suits people early in their careers who want to start a company now and need a cofounder. Pick the one that matches your stage.

What is the difference between SPC and EF?

SPC is a community for the "-1 to 0" stage, with a six-month residency and a Founder Fellowship that runs an 8-week bootcamp. EF is a team-forming programme: 12 weeks of FORM in London or Bangalore, then 12 weeks in San Francisco for teams it backs.

What does "-1 to 0" mean?

It's SPC's term for "the stage when you figure out what you want to dedicate the next 5-10 years of your life to building", before you have a company or even an idea.

Is South Park Commons an accelerator?

SPC says "We are not a traditional accelerator." Its Founder Fellowship has an 8-week bootcamp, but the residency phase that follows has no fixed end date, and the Member Residency is open-ended exploration.

Do I need an idea for South Park Commons or Entrepreneur First?

No for both. SPC's Fellowship asks you to show how you generate ideas. EF doesn't assess ideas and judges you as an individual.

Does South Park Commons accept solo founders?

Yes. The Fellowship welcomes solo applicants, with "a strong bias for applicants who can build and prototype", and SPC says it can help solo fellows search for a cofounder.

Does Entrepreneur First find you a cofounder?

It gives you a cohort to find one in. FORM is 12 weeks of meeting other members, pairing up and testing ideas. It doesn't guarantee a cofounder.

How long is the South Park Commons Founder Fellowship?

The bootcamp is 8 weeks, in person. After it, fellows move into a Fellow Residency with no fixed end date. The Member Residency lasts six months.

Where are South Park Commons and Entrepreneur First based?

SPC has spaces in San Francisco, New York and Bengaluru. EF runs FORM in London and Bangalore and LAUNCH in San Francisco.

Do I have to move for SPC or EF?

For SPC, you need to be in San Francisco, New York or Bangalore. For EF, you relocate to London or Bangalore, and again to San Francisco if EF backs your team.

When is the next South Park Commons Fellowship?

The Fall 2026 bootcamp runs until late November 2026. SPC's apply page says Spring 2027 applications will open "later this year". The Member Residency takes applications on a rolling basis.

When is the next Entrepreneur First programme?

Bangalore from February 2027 (apply by 4 December 2026 for the second of four selection rounds) and London from April 2027. The US fellowships are reviewed on a rolling basis.

Is South Park Commons hard to get into?

SPC calls itself "a highly selective community" and doesn't publish an acceptance rate. For its first Fellowship in 2021, it said nearly 1,000 founders applied and 16 fellows were chosen.

Can I keep my job during SPC or EF?

Generally no. SPC's FAQ says membership generally requires a full-time commitment, with occasional exceptions. EF is full-time and in person.

Which is better for non-technical founders?

Both lean technical. EF takes a small number of non-technical people with solid technical understanding. SPC says most members are technical, with exceptions, and welcomes domain experts.

Can I find a cofounder before applying?

Yes. SPC's Fellowship accepts teams and EF asks both cofounders to apply. Foundinity lets you look while you keep your job.
