YRI vs Ladder Internships is a choice between a startup project and a published research paper. Ladder's Startup Internship costs $3,190 for 8 virtual weeks at 5 to 10 hours a week, and the student finishes with a project for a startup, a final presentation and a letter of completion. The YRI Fellowship costs $2,997 for 10 weeks of weekly one-on-one work with a PhD mentor, and the student finishes with a first-author paper submitted to IEEE, Springer or Elsevier journals and conferences, plus ISEF and JSHS preparation on the same work.
We run YRI, so weigh this accordingly. YRI runs research mentorship, 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, linked in the Sources section. Opinions are marked.

What Ladder Internships is
Ladder connects students with startups for a structured, remote project. Its homepage lists more than 6,200 applications, 1,200 interns selected and more than 50 host companies, in fields such as AI, software, finance, healthcare, environmental science, consulting and media. Ladder runs four tracks, all 8 weeks:
- Startup Internship: the core program, a project with a startup.
- CEO Internship: the same structure, working directly with a startup CEO.
- Executive Fellowship: one-on-one work with a startup CEO.
- University Internship: for undergraduates and gap-year students.
Ladder publishes a week-by-week plan: meet the company coach and define the project in week 1, a first deliverable in week 4, a second deliverable defined in week 5, and a final presentation to the company in week 8.

What each program costs
Ladder publishes the price of its basic track. Its FAQ lists the Startup Internship at $3,190, paid in two installments, with a $200 deposit to hold the spot and the balance due after the family approves the company match. Immerse Education's 2026 guide reports the CEO Internship at $4,990 and the University Internship at $2,190. The Executive Fellowship price is not published.
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 its FAQ says roughly 10% to 20% of each cohort receives aid. Ladder says it cannot guarantee aid to everyone who requests it.
YRI has one price: $2,997, or three payments of $999. It covers weekly 1:1 sessions with a PhD mentor, an editing team on every draft, a publishing team that handles venue selection and submission, ISEF and JSHS preparation, a mentor letter of recommendation, and help at no extra cost until the paper is published. Scholarships are considered case by case. The full list is on the pricing page.
What your student does each week
At Ladder, the student works on a business or technical problem for a startup. Example projects listed by Ladder and third-party guides include AI pricing models, a go-to-market plan for a personal finance app, a churn model for an e-commerce site, a competitor analysis for a health-tech company and a whitepaper for a nonprofit. The student meets a company coach and presents two deliverables to the company.
At YRI, the student works on an original research question in their field with a PhD mentor. The 10 weeks move from finding the question, to designing the study and collecting data, to writing the manuscript, to submission and science fair preparation. The editing team reviews every draft, and the publishing team handles the submission to IEEE, Springer or Elsevier journals and conferences.
What your student finishes with
Ladder: a finished startup project, a final presentation and a letter of completion from the company. For a student pointed toward business, product or software, that is useful experience and a good line on a resume.
YRI: a first-author research paper submitted to a peer-reviewed venue, and a competition entry built on the same research. 87% of Fellows publish, 73% place at science competitions, and Fellows have been admitted to Brown, Johns Hopkins, Stanford, Caltech and Harvard.
Research is not only for lab science. One example: Karan A. joined YRI with a strong interest in markets and no research training. With his mentor he designed a Difference-in-Differences study of how short geopolitical shocks move sector stocks, and six months after enrolling his full paper was accepted at the World Finance and Banking Symposium 2026 in Riga, Latvia. For a business-minded student, that is a finance credential an admissions reader can look up. More results are on the Published Work page.
How admissions readers see each
Our opinion: internships and research show different things. An internship shows initiative and professional exposure. A first-author paper shows that a student asked an original question, answered it with evidence and had the work accepted by outside reviewers. Students aiming at research-heavy majors at selective colleges often benefit most from the second. Our guide to research mentorship versus internships explains how each reads on an application, and our YRI vs research internships page covers lab-style internships as well.
Schedule and admissions
Ladder runs four cohorts a year. The process is an application, an interview, a decision, then a deposit and a company match. Ladder reported a 10% acceptance rate for its Summer 2023 cohort. Its programs page lists a November 15, 2026 deadline for the Winter I cohort, which starts December 7, 2026.
YRI has rolling admissions and a decision within 48 hours. No research experience is needed, and the 10 weeks can start any time of year.
Who should choose Ladder Internships
Ladder is a good fit for some families, and we would rather say so:
- Your student is drawn to business, product, marketing or software and wants to see how a startup works.
- Your student does well with a fixed plan and weekly check-ins with a company.
- Your family income is $50,000 or less and Ladder's aid is open to you.
- The goal is professional experience, not a research credential.
Who should choose YRI
- The goal is a first-author paper submitted to a peer-reviewed venue, in any field, including economics and finance.
- Your student is aiming at STEM or research-heavy majors at selective colleges.
- You want ISEF and JSHS preparation from the same project.
- You want a letter of recommendation from a PhD mentor who knows the student's work closely.
- You want help that continues until the paper is published, at one price.
Questions to ask both programs
Frequently Asked Questions
Is Ladder Internships or YRI better?
They are different products. Ladder is a paid startup internship that ends in a company project and presentation. YRI is a research fellowship that ends in a first-author paper submitted to IEEE, Springer or Elsevier venues, with competition preparation included. Pick by the outcome you want.
How much does Ladder Internships cost?
Ladder's FAQ lists the Startup Internship at $3,190, in two installments after a $200 deposit. A third-party guide reports the CEO Internship at $4,990 and the University Internship at $2,190.
How much does YRI cost?
$2,997, or three payments of $999. That includes the PhD mentor, editing, submission, ISEF and JSHS preparation, a mentor letter and help until the paper is published.
Is a Ladder internship paid?
No. Interns are not paid; families pay tuition, with need-based aid available for families earning $50,000 or less a year.
Can my student do both?
Yes, though doing both in the same term is a heavy load. If a paper and a science fair result are the priority, start with the research, since peer review and fair seasons take longer to play out.
How the YRI Fellowship helps your student publish
If the goal is a published paper, science fair results and a stronger college application, the YRI Fellowship is built for it. Your student meets a PhD mentor 1:1 every week for 10 weeks, the editing team reviews every draft, and the publishing team submits the paper to IEEE, Springer or Elsevier journals and conferences. ISEF and JSHS preparation and a mentor letter of recommendation are included, and help continues free until the paper is published. More than 1,000 students from 50+ countries have joined.
