Startup Internships

Why Intern at a Startup?

Interning at a startup offers a unique chance to make a real impact from day one. Unlike large corporations, startups give interns more responsibility, flexibility, and exposure to different roles.

You’re not just watching—you’re contributing. If you intern at a startup, you’ll likely work closely with founders, learn fast, and build valuable skills that set you apart. This hands-on experience helps you grow your confidence and adaptability in a dynamic environment.

Plus, many interns for startups turn these short-term roles into full-time opportunities. Read more about the benefits of interning at a startup.

Student Testimonials on theInterna’s Internship Experience

Tom Coleman
Tom ColemanStudent - Durham
theInterna has been very helpful with not only finding me a valuable internship in a Spain but also by providing a crash course into the world of start-ups that means I can provide more value to the company I’ll be working for. The course content was perfectly balanced between concepts, tools, and practical exercises. I feel ready to hit the ground running!
Hannah Kenyon
Hannah KenyonStudent - University of Leeds
The Strategy, Sales and Digital Marketing course ran by theInterna has been truly amazing. Packed with content, diagrams and links to external platforms, I have learnt so many new things and it has broadened my areas of interest. I now feel much better equipped and have formed more of an idea of my career path when I graduate. theInterna also set me up with a brilliant internship in Spain, providing a flawless process from the initial call through to securing the placement, and it has been a pleasure having the agency as a point of contact. Without a doubt I would recommend theInterna.
Hannah Yates
Hannah YatesStudent - Cardiff University
Outstanding training and support provided by theInterna. The training comprised a variety of invaluable resources, presented clearly and concisely, with a good mixture of videos, articles and exercises to put our knowledge into practice. The calls were useful to consolidate what I’d learnt over the week and get clarity on anything I was unsure of. Not only do I feel better equipped to begin my internship, but I feel inspired to create my own startup in the near future!
Imogen Barrett
Imogen BarrettStudent - Oxford
the Interna is a fantastic organisation which feels so tailor made to your needs: you get a consultation call with theInterna to help you find the best option for an internship. The new Interna training course is an amazing free add on to boost business skills and add to your CV.
Samuel Carro
Samuel CarroStudent - Cardiff University
I personally believe that this course was so beneficial for me whilst also on my placement. Joining a Start-up can be very fast-paced sometimes, and you often have to learn on the job. Doing this course alongside my job allowed me to learn some valuable skills that I needed in future weeks! What I liked most was the flexibility of the course, there were lots of resources that you could use, but if you did not have enough time, there were summary pages that were clear and concise! It as a great and very interesting course.

Startup Internship Tips from theInterna

What Startups Look for in Interns

Startups move fast, so they value interns who are adaptable, proactive, and ready to learn. Unlike big companies, they often skip formal training and expect you to contribute quickly. To stand out when applying to internships at startups, focus on showing:

  • Problem-solving skills – Can you figure things out on your own?
  • Curiosity and initiative – Do you take action without being told?
  • Communication – Are you clear, responsive, and easy to work with?
  • Basic technical or marketing skills – Depending on the role
  • A growth mindset – Are you open to feedback and learning?

Even without experience, showing these traits can land you the internship.

Use theInterna to apply for curated roles where startups actually want interns. We guide both sides—helping founders onboard interns and helping students show up ready from day one.

Yes! theInterna welcomes recent graduates looking to break into the startup world. Many of our listings are flexible and designed for those transitioning into work life with real projects and founder access.

TheInterna focuses on students in their final or penultimate year, so we don’t offer internships to first-year students. If you’re just starting out, try exploring opportunities on platforms like LinkedIn, StudentJob UK, or reach out to university career services for early experience programs.

theInterna includes remote-first and hybrid roles from UK startups. You can filter by location or remote work to find options that match your lifestyle and learning goals.

Search theInterna for roles like Founder’s Associate or Operations Intern. We actively encourage founders to create these rare, high-trust positions—and we help both sides make them work.
