Cinder

Cinder is a Trust & Safety platform — an operating system for online Trust & Safety and content moderation teams. It unifies policy management, content review and moderation queues, investigations, automated detection, and reporting into a single workflow so platforms can enforce their rules consistently and at scale. The company (originally at cinder.co, now cinder.ai) was founded by operators with backgrounds at Meta, Palantir, and US national-security teams, and applies AI and agentic automation to content classification, case management, and enforcement. Cinder is venture-backed (Accel, and additional investors) and sits in the security / trust & safety sector. This API Evangelist profile was surfaced as a portfolio company and enriched by the pipeline; the company's public surface is behind bot protection, so API artifacts remain to be confirmed.

Cinder is profiled on the APIs.io network. Tagged areas include Company, Security, Trust and Safety, Content Moderation, and Policy Enforcement.
