How it works

There are just 5 steps to building a real company at batch0. The dates are set by the Cohort 2 calendar (Dec 14, 2026 – Feb 12, 2027).

  1. Apply

    Free. Come with an idea you want to build, or just a desire to learn. We admit students who show they'll actually do the work, not just ideas.

  2. Get a decision by email

    Applications are reviewed on a rolling basis. Each application is read thoughtfully and thoroughly by our team.

  3. Enroll

    $150.99 tuition, charged only if you're accepted. That's it. Nothing more. Refund terms are published on the refund policy page.

  4. Build season

    Validate, build, market, pitch and most importantly, transform your idea into a company.

  5. Share your work at demo day

    The cohort closes with a staff-hosted showcase of submitted demos and decks, followed by moderated written Q&A. No outside guests, funding or prizes are promised.

What you work toward

The work you will build toward, with progress depending on your effort:

  • A validated Lean Canvas

    Tested in interviews with strangers who owe you nothing.

  • A shipped v1

    Landing page, no-code MVP, or working prototype. Live and ready for the world to see.

  • A working business model

    Revenue, pricing, and unit economics you can defend on demo day.

  • A go-to-market plan

    A concrete path to your first paying customers, complete with a funnel and marketing plan.

  • An evidence-based pitch deck

    A prepared demo or narrated deck for the staff-hosted showcase.

  • 100% of your company

    batch0 takes no equity, no IP, and no royalties. Everything you build is yours.

Who runs this

batch0 is built and run by Rishabh Dagli and Shresht Chopra, two student founders. They lead the sessions and help students work through customer research, a first version and a final showcase.

Fall 2026 is the founding cohort. There are no glossy alumni stats to show you yet, and we won't invent any. What we can promise: Rishabh and Shresht run every live session themselves, read every application, and answer every parent question personally within a couple of days.

How much does it cost?

$150.99, once, and only if you're accepted; applying is free. There are no hidden fees, no upsells, and no materials costs. Reduced regional pricing applies automatically in select countries, and refund terms are published on the refund policy page.

Who runs batch0?

Rishabh Dagli and Shresht Chopra — two 17-year-old founders who build and ship their own projects, including batch0 itself. They personally review applications and run the live sessions. Fall 2026 is the founding cohort; we do not claim an alumni track record.

Who is it for?

High schoolers, ages 13–18. It's fully online, so you can join from anywhere you can make the live sessions (they're scheduled on U.S. Eastern time). Bring a real idea, a half-formed hunch, or nothing at all — the first sessions exist to help you find and refine your idea. No startup experience required.

How much time does it take?

Plan for 5–10 focused hours a week, the way you would a serious extracurricular. The live calendar on the parent page lists sessions and office hours in U.S. Eastern time; the rest is independent work toward your weekly deliverable. Session links and calendar downloads are in Events; readings and workbooks are in Course. If you miss a session, use the course materials and ask the team about catching up.

Is it really fully online?

Yes. Sessions, feedback, and demo day happen online, with live sessions inside Batch0. Cohort 2 runs Dec 14, 2026 – Feb 12, 2027. You can join from anywhere; sessions are scheduled on U.S. Eastern time.

Who are the mentors?

Rishabh and Shresht lead the cohort. Guest mentors and investors are not promised as part of tuition. Live sessions are staff-led with moderated written Q&A.

How is the community moderated?

Every program space — batch0 Chat and session chat — is moderated by the batch0 team under published community guidelines. Mentors, investors and other adults outside the batch0 team can't message students privately: they talk with students only where the team can read along, in channels like #general and, for a student's assigned mentors, their team and cohort channels. Students can message each other, and the batch0 team, privately; nobody else reads those conversations unless someone in one reports a message, which hands it to the team. Anyone can report a message, sessions may be recorded, and anything concerning goes straight to hello@batch0.org, where a human (a parent can be that human) gets a reply within a couple of days.

What is demo day?

A staff-hosted showcase of submitted student demos or narrated decks, with moderated written Q&A. Students do not take a live microphone or share their screens. Outside guests, funding and prizes are not promised.

Does batch0 take equity or own my idea?

No. You own 100% of your idea, your work, and your company, before, during, and after the cohort. No equity, no IP claims, no royalties. Sponsorship, if offered, is a non-dilutive grant.

How are applications judged?

Our team reads every application. We admit students who show they'll actually do the work; clear thinking about a problem beats a long résumé. Cohort 2 is capped at 24 students, reviewed on a rolling basis.

Build alongside Winter 2026. Be in it.
