Announcing our $10M fundraise from Khosla, The House Fund, South Park Commons, Max Levchin, and others

We started Foam to fix production errors faster. Today, we're announcing our $10M seed round, backed by Khosla Ventures, The House Fund, South Park Commons, Max Levchin, and a group of angels who've built and scaled developer tools, and a much bigger goal: replacing the entire observability stack.

What Foam is

Foam makes your system observable, catches incidents autonomously, and makes its tools available to agents — yours and ours. Ingestion, storage, and indexing are free. You pay when you or your agents use Foam.

What we've done

We started with error fixes as the wedge. Today, Foam benchmarks at 86% accuracy on Sonnet 4.6 for root cause analysis, outperforming Cursor with Sentry (~41% on Opus 4.6). We outperformed a more powerful model by building better telemetry for agents. And when developers use Foam's tools with their own coding agents, accuracy jumps from 41% to 64% — same task, better tools.

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're going after every signal in the stack: metrics, logs, and beyond. We're working with teams today to fully replace tools like Datadog, cutting their observability bill down to zero.
