Securing the frontline of digital safety

We built Cinder to outmatch the speed and scale of AI-empowered bad-actors.

Our story

We Built the Tools We Always Wanted to Have

Our founders spent years countering terrorism, child exploitation, and nation-state actors at Meta and in government. Confronting the AI accelerating those threats opened a different door: the ability to deploy Agents that could do more than flag and filter, that could actively carry out a company's mission and protect what it stands for. The result is the only solution that integrates custom cutting-edge Agents, an industry-leading platform, and the services needed to disrupt modern threats.

The values that guide our work

Customer Obsessed

We solve hard problems, spot opportunities and execute with craft and precision, because our customers and their users are counting on us. Our customers' mission is our mission.

Ship Relentlessly

We ship fast, learn fast, and iterate faster than the threat evolves. We shorten feedback everywhere including with customers, in code, and across the team.

Own the Outcome

We are here to do the best work of our careers. We are empowered to act, set a high bar for the work we deliver, see it through, and own the results.

Mission Over Ego

We put outcomes ahead of personal pride. We share context, challenge directly, and embrace feedback. We win as one. The adversary doesn't wait and neither do we. We ship fast, learn fast, and iterate faster than the threat evolves.
