About the company

Home Find Jobs Companies Post Resumes Post Jobs Blog, Alan exists to end the wait.

Health is a universal right, and we believe this right can only become real when it’s coupled with prevention. We need to stop treating health as something we repair and start treating it as something we build, every day. It’s not solely a question of willpower. It’s the healthcare system itself that needs to work for everyone, in a sustainable way.

So we are building the new standard in prevention insurance. Alan is the first company that integrates insurance, prevention, and care into a single, acclaimed user experience.

We are on an incredible journey to build a global leading company, with a unique culture. We already partner with 40K+ companies of all sizes, serving more than 1M+ members, and have reached €800M+ in ARR.

Prevention as the new norm. That’s what we’re building with our team of 800+ people. If it speaks to you: we’re hiring across France, Spain, Belgium, and Canada. And beyond.

Build the backbone of Alan’s financial systems

At Alan, billing is a platform that powers reliable, accurate, and scalable financial operations across multiple countries and products. Our mission is to turn complex, high-volume billing flows into systems that “just work,” so customers and members can focus on what matters.
