ABOUT COGENT

Cogent is an Applied AI Lab building the next generation of AI agents for cybersecurity. AI has fundamentally changed how attacks happen, allowing malicious actors to operate at unprecedented speed and scale. Cogent’s "AI Taskforce" assesses petabytes of enterprise data to remediate these issues before critical breaches occur.

To stay at the cutting edge, we blend frontier research with real-world execution. Alongside our core product work, Cogent Research serves as our applied AI lab, providing the research horsepower needed to make truly agentic security workflows a reality.

Since coming out of stealth, Cogent has experienced rapid growth. We partner with Fortune 500 companies to secure some of the most complex production environments in the world.

We’re backed by Greylock and we’ve built a team with the best minds in applied AI. Our team is comprised of people from:

- Top universities like Stanford, Berkeley, Penn, Duke, Carnegie Mellon, Waterloo

- Unicorn, high-growth companies like Scale AI, Databricks, Stripe, Tesla, Coinbase

- World class cybersecurity experts from Wiz, Abnormal AI, Zscaler

- Preeminent research labs like Deepmind and SAIL

As we work with our first design partners, Cogent is building a suite of backend services and integrations that will power our autonomous AI workers. We are looking for talented, ambitious Backend Senior and Staff Engineers who are excited to build in the Applied AI space.
