Startup Internships: Find Paid Roles in the US and Canada

Startup internships are easier to search for when you stop expecting a big-tech recruiting calendar. To find a paid role, you need a target list, proof you can contribute, and a clear ask. This guide gives you a search timeline, verified sources, an outreach plan, and a way to assess the offer.

This article is general information, not legal advice; check the official sources below or consult your school's international student office, a US immigration or employment attorney, or a regulated Canadian immigration consultant or lawyer.

When to apply for startup internships

Start early, but keep searching after the campus recruiting rush. Harvard's current tech recruiting guide contrasts big-tech applications in late summer or early fall with startups' more just-in-time hiring. That means a startup may recruit closer to the internship's start date rather than reserve a summer cohort far ahead.

Don't turn that pattern into a reason to wait. Some startups run planned programs, while others need a specific project owner once budget and supervision are available. Cornell's recruiting timeline notes that tech startups may still interview through June; that is a possibility, not a guaranteed opening.

For a startup internship in summer 2027, use this suggested planning calendar, not an employer deadline schedule:

For a fall, winter, or co-op term, work backward from your available start date. Tell employers your end date and whether your school must approve the placement. Don't assume their definition of “summer” matches your academic calendar.

Where to find paid startup internships

Use boards to discover companies, then check the original employer posting. Your startup job search guide can help you build the broader target list. Keep internship-specific details in a separate tracker so full-time roles don't crowd out your search.

Wellfound's official search instructions confirm internship, company-stage, and employee-count filters. They also explain that a salary filter can hide postings without listed pay unless you include those jobs. Keep a discovery search broad, then ask employers about compensation before investing in interviews.

Try these copy-paste search queries outside the boards:

site:jobs.ashbyhq.com intern Toronto

site:job-boards.greenhouse.io internship Canada

site:boards.greenhouse.io intern engineering

site:jobs.lever.co internship marketing

These queries are discovery tools, not proof that a role remains open. Search indexes can retain old pages. Confirm the listing from the company's own website and read the term in the description, not just the headline.

Choose a team and show a useful work sample

Choose a function before pitching yourself as someone who can “help with anything.” A founder should be able to picture your contribution without designing an entire role for you. Pick a bounded task that fits your skills and could have a clear reviewer.

Illustrative project ideas, not claims about actual companies:

• Engineering: Build a small demo using public documentation, add tests, and explain one limitation.
• Data or business analysis: Clean a public dataset and show how you'd check the reliability of an onboarding metric.
• Design: Annotate a confusing signup flow and propose an accessible alternative.
• Marketing: Draft a customer-specific landing page and explain the audience and distribution plan.

Use public or synthetic data. Label assumptions, separate your work from teammates' contributions, and don't claim a business result you haven't measured. A working link with a short explanation beats an oversized presentation that hides what you actually did.

Before applying, check the product, intended customer, team, and work arrangement. Look for a named supervisor and a realistic project, not just “founder exposure.” At a small startup, ownership can be valuable, but you should not be expected to replace an experienced employee without training.

Track company, source URL, role, pay status, location, term, supervisor, authorization questions, application date, contact, and next action. Mark unknown details as unknown. Don't quietly convert “compensation discussed later” into “paid.”

Are unpaid startup internships legal in the US and Canada?

Prioritize paid startup internships. A company's lack of funding is not a good reason for you to absorb its operating costs. Ask for the cash rate, currency, expected hours, and payment schedule in writing; treat any equity as separate from that conversation.

US: the primary beneficiary test

As of November 2026, the Department of Labor's Fact Sheet 71 describes the primary beneficiary test for interns at for-profit employers under the Fair Labor Standards Act. It considers these seven factors, paraphrased here:

• Whether both sides understand there is no expectation of compensation.
• Whether training resembles an educational environment.
• Whether the internship connects to formal education through coursework or academic credit.
• Whether it accommodates academic commitments and the school calendar.
• Whether its duration is limited to beneficial learning.
• Whether the work complements, rather than displaces, paid employees while providing significant educational benefits.
• Whether both sides understand there is no entitlement to a paid job afterward.

These are flexible factors, not a pass/fail checklist; no single factor decides the outcome. If the analysis shows you are an employee, you are entitled to minimum wage and overtime under the FLSA. Conditions apply; check applicable state law with your school or counsel as well.

Academic credit alone does not settle the question. If a founder proposes unpaid work, ask your career center to review the actual duties and training arrangement. Don't rely on the label “intern” or a promise that payment will start after fundraising.

Ontario and federally regulated Canadian workplaces

As of November 2026, Ontario's employee-status guide says interns receiving training in skills used by the employer's employees are generally employees under the Employment Standards Act. It lists exclusions for work under programs approved by universities, colleges of applied arts and technology, or registered career colleges, and school-board-authorized secondary-school work experience. Conditions apply; confirm that the actual program qualifies rather than assuming student enrollment is enough.

As of November 2026, the federal labor standards page distinguishes interns, who must receive at least minimum wage, from qualifying student interns who may be unpaid. That framework applies to federally regulated workplaces, with student-intern eligibility and documentation conditions.

For work outside that federal framework, check the province's employment standards with your school's placement office. Employment-law classification and immigration permission are separate questions. Approval under one does not answer the other.

International students: confirm permission before accepting

US students on F-1 status

As of November 2026, DHS guidance requires eligible F-1 students using curricular practical training, or CPT, to obtain authorization from their designated school official before starting that training. Training must relate to the major and meet curriculum requirements; prior-study and other conditions apply. SEVP's August guidance rejects optional elective-based CPT and requires practical training for all students in the relevant curriculum. That guidance is under litigation, with a preliminary-injunction hearing scheduled for November 6, 2026; a scheduled hearing is not a court pause. Ask your DSO whether this placement can be authorized under current school policy, even if it is unpaid. For post-graduation planning, read the startup OPT guide, but don't treat OPT as interchangeable with CPT.

Canadian students and co-op placements

As of November 2026, IRCC says eligible post-secondary international students no longer need a separate co-op work permit for required student work placements, following its April 1, 2026 change. Secondary students still need a co-op permit. Conditions apply, including full-time enrollment in a qualifying post-secondary program at a Canadian designated learning institution, an initial study permit allowing on-campus work, a valid study permit or an extension application submitted before expiry, and a school letter confirming the placement requirement. Work placements must total 50% or less of the study program; exclusions and stop-work conditions also apply. Ask your international student adviser to confirm eligibility; an optional summer job is not automatically a required placement. For later planning, see the Canadian international-graduate job guide.

Cold email a founder with a two-week outreach plan

Contact a founder when the company is small and no relevant hiring contact is listed. Otherwise, choose the team lead or recruiter responsible for the work. Use a public professional contact route, and follow any application instructions rather than trying to bypass them.

Your message needs a product observation, relevant evidence, availability, and a modest ask. Don't propose unpaid production work to get attention. Use the founder cold-email guide for more on choosing the contact and personalizing the message.

Illustrative email for a hypothetical B2B software startup. Replace the product observation and demo reference with truthful details:

Subject: Paid engineering internship — onboarding demo

Hi,

Your public setup guide asks new users to move between the dashboard and API documentation. I built a small demo that keeps those steps together, with tests and notes on its limitations. The demo link is below.

I'm a computer science student looking for a paid summer internship. I could contribute to onboarding tools or integration tests with an engineer reviewing my work. My available dates and resume are below.

Are you planning an intern project in that area? If someone else owns it, could you point me to them?

Thanks for considering it.

Use this recommended two-week plan. The numbers are activity targets, not promised response rates:

Applications and messages can target the same company; don't count them as separate opportunities. If suitable postings aren't available, keep researching instead of applying to unrelated roles to hit a quota. Respect any stated response timeline or request not to follow up.

In your follow-up, restate the proposed contribution and ask whether the team expects to hire an intern. Then move on if there is no response. A smaller, well-researched list is more useful than mass email with a changed company name.

Turn a startup internship into a return-offer conversation

Discuss the possibility before joining, without treating it as a promise. Ask who decides on return offers, whether the team expects future headcount, and what evidence would support the decision. Confirm how your graduation date fits their needs.

Use this suggested structure after you start:

1. First week: Agree on a project, reviewer, expected output, and definition of done. Write down what you need to learn.
2. Every week: Send a brief update covering completed work, blockers, and the next priority. Ask for feedback while you can still act on it.
3. Midpoint: Ask what is missing for a strong evaluation and whether a future role is financially realistic.
4. Before the end: Present results, document your work, and ask for a decision process and timeline.

Keep evidence of your own contribution: shipped code, accepted designs, completed analyses, or useful documentation. Separate outputs from outcomes. If a metric changed, explain the measurement and what you can reasonably attribute to your work.

Ask permission before saving anything for a portfolio. Leave a clean handoff so the team can maintain what you built. If no role is available, request a reference and introductions to relevant teams; budget constraints do not automatically mean your internship went badly.

Next steps

• Write down your available dates, work locations, and minimum acceptable cash compensation.
• Confirm school and work-authorization requirements before promising a start date.
• Build your target list and choose a work sample tied to a real team need.
• Start the outreach plan, then evaluate opportunities on pay, supervision, project scope, and realistic future headcount.
