Is Ladder Internships legit? Yes. Ladder Internships is an established, selective program, founded by Harvard entrepreneurs, that places high school students in fully virtual eight-week projects with startups; its basic Startup Internship costs $3,190, with full or partial aid for families earning $50,000 or less a year. The key thing to understand before paying is that Ladder is a paid program, not a paid job: the family pays tuition, and the student finishes with a startup project, a final presentation and a letter of completion, not research or a publication.
This review is written by a competitor, YRI Fellowship, and we say that upfront. YRI runs research mentorships, not internships, so the two programs overlap less than most comparisons. Facts about Ladder come from Ladder's own pages and named third-party guides as of November 2026, all linked in the Sources section. Opinions are marked.
What Ladder Internships is
Ladder connects high school students with startups for a structured, remote project. One of its co-founders, Stephen, writes on Ladder's About page that he started it after Harvard and a few years at McKinsey, with two college friends who went on to found startups. Ladder's homepage lists more than 6,200 applications, 1,200 interns selected and over 50 host companies.
Ladder runs four tracks, all eight weeks and five to ten hours a week:
- Startup Internship. The core program: a project with a startup, with eight sessions with the host company.
- CEO Internship. The same structure, working directly with a startup CEO who Ladder says comes from a FAANG-level company or a top 20 university.
- Executive Fellowship. One-on-one work with a startup CEO.
- University Internship. For undergraduates and gap-year students, matched to startups that have raised or generated over $1 million.
Host fields include AI and machine learning, software engineering, finance and fintech, healthcare and biotech, environmental science, consulting, media and nonprofits.
What students do in eight weeks
Ladder publishes a week-by-week outline:
| Week | Milestone |
|---|---|
| 1 | Meet the company coach and define the project |
| 2 to 3 | Work on the project with the coach and finish a first draft |
| 4 | Present the first deliverable to the company |
| 5 | Meet the company mentor and define the second deliverable |
| 6 to 7 | Work with the coach on the second deliverable and finalize the project |
| 8 | Present the final project to the company |
Third-party guides add detail: a mandatory weekly 45-minute meeting with an intern manager, and a Ladder coach as a second mentor. Example projects Ladder and guides list include AI pricing models, a go-to-market plan for a personal finance app, a research report on nutrient and disease interactions, a churn model for a Y Combinator-backed e-commerce site, a competitor analysis for a health-tech company and a whitepaper for a mental health nonprofit. Ladder says past interns have coded technical prototypes and built pitch decks for founders.
At the end, the student has a finished project and a letter of completion from the company.
What Ladder Internships costs
Ladder publishes the price of its basic track in its FAQ. Prices for the other tracks come from a third-party guide.
| Track | Price | Source |
|---|---|---|
| Startup Internship | $3,190, in two installments | Ladder FAQ |
| Startup Internship, earlier 2026 | Reported at $2,990 | Immerse Education |
| CEO Internship | Reported at $4,990 | Immerse Education |
| Combination (CEO plus mentored research) | Reported at $7,400 | Immerse Education |
| University Internship | Reported at $2,190 | Immerse Education |
| Executive Fellowship | Not published |
A $200 deposit holds the spot, and the balance is due after the family approves the company match. Third-party guides report that the deposit is refunded in full if the student declines the match. Ladder says tuition covers intern training, the managers who run the company work and operating costs. For how this compares with research programs, see how much high school research programs cost.
Financial aid
Ladder offers full and partial need-based aid. Its application page says a family may be eligible with an annual income of $50,000 or less, and that Ladder may ask for tax returns. To apply, the student selects "Financial Aid Required" on the form.
| Aid fact | Ladder's figure |
|---|---|
| Income guideline | $50,000 a year or less |
| Share of each cohort on aid | About 10% to 20% |
| Students aided so far | Over 150 (FAQ); "100+ students supported" (application page) |
| Total aid given | $204,000 and up |
Ladder calls the aid process competitive, and aid cannot be guaranteed.
Admissions and deadlines
The process is a written application, an interview, a decision, then a deposit and a company match. Ladder reported a 10% acceptance rate for its Summer 2023 cohort, with 700 applicants for 70 spots; a Lumiere guide reports Ladder told it a later spring cohort was 20%. Ladder looks for self-motivated students with strong communication skills.
There are four cohorts a year: spring, summer, fall and winter. The next posted deadline is November 15, 2026 for the Winter I cohort, which starts December 7, 2026. The Spring 2026 deadline was February 8, 2026; 2027 spring and summer dates are usually posted in the fall, so check the official page.
Where Ladder Internships is strong
- Startup exposure early. Very few programs put a high school student in weekly contact with a founder. For a student curious about business, product or software, that is valuable.
- Structure. A fixed eight-week plan with two deliverables, a coach and a final presentation keeps the project from drifting.
- Workable hours. Five to ten hours a week fits alongside school.
- Fully remote. Students join from anywhere, with no travel or housing cost.
- Published price and aid rules. Ladder posts its base price and an income guideline, which many programs do not.
- Breadth of hosts. Over 50 companies across AI, finance, health tech, climate and media.
Where families should look closer
- You pay to intern. At $3,190 for about 40 to 80 hours of student work, this is a training program with a startup attached. That is a fair product. Just do not describe it on an application as if the company hired your child.
- Host size varies. Some hosts are well funded; others are early. One host on Ladder's own companies page lists raising over $100,000. Ask which company your child will be matched with and what the founder's time commitment is before approving the match.
- Project scope. Guides note that roles are limited to what a high school student can handle in eight weeks and that contributions are expected quickly. Market research and pitch decks are common outputs.
- The admissions statistic. Ladder reports that interns were 1.66 times more likely to get into a top 20 university, based on a survey of 85 interns. A self-selected group of motivated, often well-resourced students would likely beat the average applicant anyway. Treat it as marketing, not evidence.
- The output is not research. There is no paper, no peer review and no science fair entry unless you pay for the combination track. For STEM-focused students aiming at selective colleges, that matters.
Opinion: a Ladder internship can be a good line on a résumé for a student pointed toward business or startups. It is a weaker fit for a student whose application needs to show original work in a field. Our guide to research mentorship versus internships explains how admissions readers weigh each.
How YRI compares, since you will ask
YRI Fellowship is a different product: research, not an internship. Each Fellow works 1:1 with a PhD mentor for 10 weeks toward a first-author paper submitted to a peer-reviewed IEEE, Springer or Elsevier venue, with ISEF and JSHS preparation included and a letter of recommendation from the mentor. It costs $2,997, with a 3-month payment plan and scholarships case by case, and mentorship continues at no extra cost until the paper is published. 87% of Fellows publish, and 73% place at competitions.
| Ladder Startup Internship | YRI Fellowship | |
|---|---|---|
| Price | $3,190 | $2,997 |
| Length | 8 weeks | 10 weeks, then supported until published |
| Weekly time | 5 to 10 hours | Built around a weekly 1:1 session |
| Who guides the student | Startup host, company coach, Ladder manager | PhD mentor |
| Output | Startup project, final presentation, letter of completion | First-author paper submitted to a peer-reviewed venue |
| Competition prep | Not a stated feature | ISEF and JSHS included |
| Aid | Full or partial, income $50,000 or less | Scholarships case by case, 3-month plan |
If your child wants their own name on a published paper and a science fair project from the same work, the YRI Fellowship is built for that. For a broader view of internship-style options, see our research internships guide and the side-by-side on YRI versus research internships.
Other ways to get startup experience in high school
Ladder is not the only route. Students can email local founders directly with a specific offer of help, work for a family business, run a school club venture or build their own small product. Our lists of passion project ideas and how to start a nonprofit in high school are good starting points. These cost nothing, though they take more initiative and lack Ladder's structure.
Who should pick Ladder Internships
