  • Extern
    Extern (w2017)Active • 35 employees • New York, NY, USA
    At Extern, we’re solving the experience gap. Extern created the remote Externship, a skill-building work experience that is easier for students to access, and easier for companies to run, than an internship. Our mission is to help anyone discover and launch their career through professional experiences available anywhere at any time. Since 2020, we’ve created and powered Externships on behalf of companies from Fortune 500s to startups that have enabled tens of thousands of students to build real experience and open doors to incredible opportunity. After spending $100K on average for a 4-year degree, graduates find that almost 40% of entry level jobs on Linkedin required 3+ years of work experience. Internships are how many college students get this kind of experience, but the demand for good internships outstrips the supply. Internship programs are difficult to scale, they favor students who already have social capital, and they’re time-consuming for employers to run. Externships are short, online, project-based work experiences that employers can offer to hundreds of students using less resource and employee time than it would take to support an intern. Extern makes the complex process of running an Externship completely turnkey with software and industry experts which in turn makes professional experience more accessible to more students. By making work experience more accessible, Extern is driving the rapid mobility and upskilling needed for a new economy. We envision a world where anyone can access work experience as a form of education – no matter their background, experience, or socio-economic status. Come join our movement to reshape work, education, and credentialing for future generations with the Externship. Extern was born out of a pivot from Paragon One (W17) which initially focused on providing students with a career center-as-a-service platform, connecting them with industry professionals to receive career coaching and guidance. Backed by Y Combinator, Foundation Capital, Launch Fund, University Ventures, and Learn Capital.
