Working at

We're empowering educators with total control in their hands and we’re helping the world to teach. We do this by revolutionising how schools and nurseries find the best educators. We do this by empowering educators with full-career control. And we do this because we must. Because by 2030, up to 69 million classrooms and nurseries won’t have a teacher. But with a push of a button, supply educators can find, choose, and book every job that fits them. With a push of a button, schools and nurseries can instantly and easily find educators. With a push of a button, we simplify, modernise, and improve education for everyone everywhere. And with a push of a button, we can help those 69 million classrooms and nurseries learn another day. In 2015, Kristoffer and Gustav, our Head of Product and CEO co-founded Humly in Gothenburg, Sweden. But before the C-Suite, they were college students and supply teachers, dealing with the same problems many face with agencies: the last-minute work calls, the calls that don’t come, the lack of power or say in your career, and so much more. So they built a home where educators are as important as the job itself. They built Humly, so educators can have the power to choose when, where, and how much they work – simply and easily, without hassle. They built Humly so every eligible educator can find the classroom and nursery that’s right for them.
