Horizons was designed for students from the world’s best universities. The Horizons Internship program seeks to continue to find top talent, even earlier, by opening up our experience to high school students.

We believe internships should be a learning experience - but after working with hundreds of college students we realized many weren't gaining valuable skills in their internships!

Our high school interns program is an opportunity for the worlds's top talent to forge lifelong connections with the nation's top undergraduate students by living and working in the same room, learn about tech careers via exclusive speaker sessions, refine job skills via a rigorous, applied programming curriculum and accelerate potential in engineering and entrepreneurship by gaining real work experience, all in one intense summer.

Learn to Code and build Web Applications

Learn how to build web and mobile applications via an intensive full-stack JavaScript curriculum that has pushed each and every one of our students to their limit. Our curriculum has been built by engineers at leading technology companies like Khan Academy, Salesforce, NerdWallet, and Optimizely.

Our course was designed for students at some of the nation's best universities. We are now opening it up to high schoolers!


Horizons is not just a School of Technology. We are a group of entrepreneurs (Y-Combinator, DreamIt Ventures, Wharton), former engineers in technology (Khan Academy, Salesforce, NerdWallet), and Investors (Investors in over 80+ companies including SpaceX, Reddit, and Built Robotics) who are passionate about bridging the gap between traditional education and the tech world.

The unique offering about our high school program is that you'll apply the programming skills you gain by interning for a Horizons portfolio company/project, putting your skills to real use in opportunities once reserved only for experts and industry insiders!

For those aspiring entrepreneurs, you can use this time to build your own products under the mentorship of our world-class team.

Meet Leaders in Technology

Getting access to Silicon Valley's tech elite at such a young age can be a transformative experience. We broaden students perspective and knowledge by bringing in successful entrepreneurs, engineers, operators and investors. Students will learn about new industries, building companies, and career paths. Prior students rave about the lessons they learned about technology, business and life.

Speakers include Cory Levy (Creator of AfterSchool), Matt Cohler (Employee #5 at Facebook and Co-Founder of LinkedIn), Jeff Jordan (President at PayPal and CEO at OpenTable), Keith Rabois (Vice President at PayPal and Founding Team at Square).


Our flagship program was created for high-achieving university students interested in technology. You'll be treated as equals with students who were in your shoes just a few years ago. Your peers will include National Mathematics Olympiad winners, Y-Combinator finalists, and Perfect scorers on the ACT/SAT and Formula 1 Racecar drivers.
