Sentry

Sentry provides application monitoring software that collects errors, logs, session replays, traces, profiles and metrics, linked by a shared trace. Its Seer AI debugging agent uses this context to explain failures and generate patches, and the product also includes uptime, cron and release health monitoring plus an MCP server for coding agents.

Customers are software developers and engineering teams, from solo developers on a free plan to large organizations; the website names customers such as Disney, Atlassian, Cloudflare and Anthropic. Revenue comes from tiered SaaS subscriptions (Developer, Team, Business and custom Enterprise plans) with additional event volume priced separately.

Sentry was founded in 2011 by David Cramer and Chris Jennings and began as an open-source project; its legal name is Functional Software, Inc. The website lists offices in San Francisco, Seattle, Toronto and Vienna, and states $217M raised in 6 funding rounds. The careers page lists 46 open positions, mainly in engineering, security, support and customer success, located in San Francisco, Toronto and Vienna, with some roles in Amsterdam and New York City.
