Most startup applications open with the same question: what are you building?
South Park Commons opens somewhere else. Its application asks what you've done, what you've made, and what you can't stop tinkering with. The examples it gives for "prior work" include a gold medal competitive programmer, a Division 1 college athlete, and someone who built a $500,000 window washing business in college. Then it tells you to brag.
That says a lot about how SPC picks people. It backs technologists at the stage before a company exists, so the main evidence it has to go on is you.
This guide covers the paths into SPC, the current Founder Fellowship terms, what SPC expects from members, and how to answer each part of the application.
What Is South Park Commons? The "-1 to 0" Community Explained
South Park Commons is a community and venture fund for technologists in the earliest stage of company building. SPC calls this stage -1 to 0: the period when you figure out what you want to dedicate the next five to ten years of your life to building.
Most programs start at zero, with a team, an idea, and often a product. SPC starts before that. As founder Ruchi Sanghvi puts it, if 0 to 1 is about product-market fit, -1 to 0 is about founder-market fit.
A few numbers give a sense of the place:
- Founded in 2016: it began as ten people reading AI papers around Ruchi Sanghvi's dining table, after she left Facebook and Dropbox
- A community of more than 1,200 members: about 175 are active at any time, across hubs in San Francisco, New York, and Bengaluru
- A 70/30 split: about 70% of members aim to start a company, and 30% are researchers and experts going deeper in a field
- $575M Fund IV: announced in August 2026, bringing SPC to $2B in assets under management
You can read more about how it started on SPC's Our Story page.
Who Has Come Through South Park Commons
SPC's member list explains why getting in is competitive. A few examples from its own residency page:
- Scott Wu: a three-time IOI gold medalist who joined in 2017 and later co-founded Cognition, the lab behind Devin
- Tuhin Srivastava: a former data scientist at Gumroad who explored widely at SPC before founding Baseten
- Amit Jain: worked on computer vision at Apple, then co-founded Luma AI at SPC
- Anurag Goel: Stripe's eighth employee, who founded Render out of the community
- Tom Brown: joined to explore a consumer idea, got pulled into a peer ML group, and went on to lead GPT-3 engineering at OpenAI before co-founding Anthropic
- Ashton Eaton: two-time Olympic decathlon gold medalist, who joined the Member Residency in 2018
The range is deliberate. SPC describes its primary product as talent curation.
Three Ways Into South Park Commons: Residency, Founder Fellowship, or Seed Funding
SPC's application starts by asking where you are today. Your answer decides which path you're applying for.
| Path | Who it's for | What you get |
|---|---|---|
| Member Residency | Technologists exploring what's next who aren't ready to raise | Up to 6 months in the community, with no fees and no equity |
| Founder Fellowship | Founders further along, usually with an early team and a high-conviction north star | $400K upfront for 7%, plus $600K guaranteed in your next round |
| Seed funding | Founders who have started a company and are raising | Seed checks of up to $10M from SPC's fund |
Many members start in the Residency and join the Fellowship once they have a firm idea. If you plan to fundraise soon, SPC may ask you to apply for the Fellowship instead of the Residency.
South Park Commons Founder Fellowship Terms: \$400K Upfront, \$600K Guaranteed
The Founder Fellowship is SPC's best-known program, and its terms are one of the main reasons founders apply.
- $400,000 for 7% equity: on a SAFE, funded immediately on acceptance, even if the cohort hasn't started yet
- $600,000 guaranteed in your next venture round: so you start your seed raise with part of it committed
- Lifetime membership: Fellows become lifetime members of the SPC community
- Startup credits: up to $1M in credits and perks from companies including Anthropic, OpenAI, Microsoft, Google Cloud, AWS, Baseten, Render, and Figma
- Two cohorts a year: one in spring, one in fall, with applications reviewed on a rolling basis while each window is open
The math is worth a second look. $400,000 for 7% implies a valuation of about $5.7M, well above most accelerator deals. For a comparison across programs, see our accelerator equity and dilution guide.
Note: SPC's Fall 2026 Fellowship applications are closed, and the Spring 2027 window opens later this year. In past spring cycles, applications closed in early February and the bootcamp ran from late March to late May. Confirm current dates on the apply page.
What Happens Inside the SPC Founder Fellowship
The Fellowship has no demo day and no forced timeline. When you're ready to raise, SPC makes introductions to investors.
It runs in two phases:
- Bootcamp: an intensive period of about eight weeks, worked in person from an SPC office, with roughly one partner for every two companies
- Residency: teams stay in the community for as long as it takes to reach conviction and prepare their next raise
Partners help Fellows identify the right market, build a first product, find early customers and teammates, and raise follow-on funding.
What SPC Expects From Members
SPC's FAQ lists one expectation: that members show up. That means:
- Working from SPC's spaces through the week: so you need to live in San Francisco, New York, or Bengaluru
- Committing full time: members generally can't hold a full-time job, with rare exceptions for things like visas or vesting
- Staying active in the community: in the private Slack, at events, and in your areas of expertise
Residents spend their time in peer accountability groups, learning forums, workshops on new technologies, and roundtables with industry leaders such as Satya Nadella, Vinod Khosla, and Fei-Fei Li.
Note: SPC can't sponsor visas directly, so international applicants should plan their work authorization before applying.
Why South Park Commons Rewards Conviction Over Speed
Ruchi Sanghvi's essay on -1 to 0 tells the story of Anurag Goel. As Stripe's eighth employee, he could have raised a seed round on his résumé alone, and he had an AI product idea investors liked. He didn't have conviction, so he joined SPC instead. He spent his time testing hypotheses with the group until he built conviction in a different problem: the need for a new kind of cloud provider. That became Render.
The lesson runs through everything SPC does. Raising money without conviction is easy. Spending years on the wrong idea afterward is the expensive part. SPC wants people willing to treat the search for an idea as a full-time job.
That shapes the application too. Showing you can explore well counts as much as showing you've already picked a direction.
What South Park Commons Looks for in Applicants
Based on its application and program materials, three signals stand out:
- Evidence of exceptional work: your strongest accomplishments and two or three artifacts that show the quality of your work
- Curiosity and range: the side projects, experiments, and rabbit holes that show how you explore
- Readiness to make it your focus: SPC looks for people ready to make figuring out what's next their primary job
The thread connecting all three is talent density. SPC's value comes from the people in the room, so it selects for people who will raise the level of that room.
How to Apply to South Park Commons Step by Step
- Choose your path: Residency if you're exploring, or Funding if you've started a company and are raising
- Write your background and prior work: under 1,000 characters
- Share two or three artifacts: links that show the quality of your work
- Describe your side projects and curiosities: under 1,000 characters
- Submit and wait for a reply: SPC reviews every application, usually within one to three weeks
- Interview: if SPC moves forward, it invites you to an interview to learn more about you
Tip: if you're applying to the Residency with a cofounder, each of you applies separately and notes the other. Teams applying for funding submit one application together.
How to Answer the SPC Application: Background, Artifacts, and Curiosities
The application is short, so each answer carries weight.
Background and prior work: lead with your strongest proof
SPC asks you to brag, so do it plainly. Lead with your most impressive, most specific accomplishment, then add one or two more. Outcomes beat titles: "built the inference pipeline serving 40M requests a day" says more than "senior engineer at a large company."
Artifacts: let the work speak
Pick two or three links someone can open and judge in a few minutes:
- A repository, paper, product, or demo you built
- A technical write-up that shows how you think
- Something you shipped outside work that people used
Two strong artifacts beat five average ones.
Side projects and curiosities: show how you explore
This question tells SPC how you'll spend your time in -1 to 0. Describe the experiments you've run, what you learned, and what keeps pulling you back. A specific rabbit hole reads better than a list of interests.
Residency or Fellowship: How to Choose the Right SPC Path
Apply to the Residency if:
- You're exploring several directions and aren't ready to raise
- You're open to research, open source, or writing as well as starting a company
- You want peers and time to build conviction before committing
Apply to the Founder Fellowship if:
- You have an early team and a strong sense of the market, idea, or product you want to pursue
- You can work full time and in person through the bootcamp
- You want capital and partner support now
If you've already started a company and you're raising, the seed funding path is the better fit. SPC considers your company's progress in its evaluation.
Mistakes That Weaken a South Park Commons Application
- Writing a pitch instead of a profile: SPC is assessing you, so a polished idea with thin evidence of your own work is a weak trade
- Vague accomplishments: "led a team" without scope or results gives reviewers nothing to evaluate
- Too many artifacts: a long list of links signals you couldn't pick your best work
- Choosing the wrong path: applying to the Fellowship without a clear north star, or to the Residency when you plan to raise in a few months
- Ignoring the location and full-time rules: if you can't be in SF, New York, or Bengaluru full time, plan for that before applying
How South Park Commons Compares to Other Founder Programs
- Versus Y Combinator: YC expects a team and usually a product, and runs a fixed batch with Demo Day. SPC starts earlier, invests at a higher implied valuation, and has no demo day
- Versus Antler and Entrepreneurs First: both back founders before the idea, with a focus on cofounder matching. SPC's Fellowship writes a larger upfront check, and its Residency charges no fees and takes no equity. See Antler vs Entrepreneur First for that comparison
- Versus traditional accelerators: SPC's Residency works more like a community than a program, with no curriculum to complete
For more programs that back founders before they have an idea, see our guide to startup programs for founders without an idea, or browse top Y Combinator alternatives.
Build Your Body of Work Before You Apply
SPC's application rewards evidence: things you've built, shipped, or proven. Founders who arrive with a working prototype, early users, or a sharp technical write-up give reviewers something concrete to judge, and they get more out of the Fellowship because they start from real signal.
