Find the LLM failures your monitoring misses.

Brevva pinpoints the step that broke the next in your LLM chain — using statistical cascade analysis, not just error counts.

We'll email you when invites open. Your address is only used for waitlist updates.

What Brevva does

See which step actually broke

Statistical cascade detection spots when one step's failure causes the next — something error counts can't tell you on their own.

See what's bleeding money

Per-provider and per-model spend with completeness signals. Catch the slow expensive model still serving traffic a cheaper one could handle.

Cross-team reliability data

See how each model actually performs in production — anonymous performance data pooled from opted-in customers. Error rates, latency, cost.

“Step 3 (your Anthropic call) caused 89% of Step 4’s failures last week.”
What Brevva surfaces. Most monitors would point you at Step 4 instead.
