How We Work

Doppel fosters a culture where curiosity, teamwork, and ownership thrive. We prioritize customer needs, actively listening and responding with speed.

Expect a low-ego, high-trust environment where you're supported and encouraged to grow.

This AI-native approach allows us to automate threat detection, classification, and takedowns, reducing analyst workloads by 80% and mitigating threats in minutes, not hours. You'll contribute to a system that adapts as attacker behavior changes, focusing on solving deeply technical problems to protect the internet.
