We started foam to fix production errors faster. Today, we're announcing our $10M seed round and a much bigger goal: replacing the entire observability stack.

What foam is

foam is an OpenTelemetry-native platform that is always listening to all of your telemetry. When it notices something worth acting on, it finds the root cause and pings your team on Slack with the fix. Built to give agents, yours and ours, the leverage to alert, monitor, and fix.

What we've done

We started with error fixes as the wedge. Today, Foam benchmarks at 85% accuracy on Claude Sonnet 4.6 for code errors, outperforming Cursor with Sentry on Claude Opus 4.6, which came in at ~41%. We outperformed a more powerful model by building telemetry for agents.

We accomplished this thanks to feedback from early partners at Together AI, Braintrust, and Perplexity, who believed in the vision early.

What's next

Now we are going after every signal in the stack: metrics, alerts, and beyond. We are working with teams today to fully replace tools like DataDog, driving their observability costs down by 90%.
