Vapi raised $50M Series B and immediately rebuilt the dashboard, here's what actually changed
So Vapi closed a $50M Series B from Peak XV, they've now done 1 billion calls, and they're powering Ring, Intuit, ServiceTitan. Cool. But the second you log in this week you can see where part of that money went, because the agent builder looks completely different.
Spent the last few days rebuilding agents on it. Here's what's worth knowing if you haven't logged in yet:
The wins:
- Logs are now ON the agent page. FINALLY. No more bouncing to Observe > Logs > filter by assistant just to check what your agent did on the last call. This alone saves me probably 50 clicks a day.
- Transcriber, model and voice are now top-level on the assistant page. Click into any of them and a sidebar opens with everything (provider, language, fallback, denoising, smart endpointing). Way less scrolling.
- Fallbacks are first-class citizens now. You can set fallback transcriber, model AND voice from the same panel. Pro tip if you're new: never set the fallback to the same provider as the primary. If OpenAI goes down, your fallback to OpenAI also goes down. Pick a different vendor.
- Structured outputs and scorecards have replaced the old summary, success eval, and structured data fields (those are deprecated now). Structured outputs are now created globally and assigned to assistants, same model as tools. Build once, attach everywhere.
- Monitors are (fairly) new. Set them up to catch things like transcriber request failures across all assistants, with thresholds and Slack/email notifications. Production hygiene baked in.
The small stuff that still annoys me:
- End call is no longer a toggle, you have to create an End Call tool and assign it. Fine once you know, but I broke an agent the first time because I assumed it carried over.
- The old layout toggle is hidden under the three dots top right. If you panic on first login, that's your escape hatch.
My humble opinion: the rebrand especially, but also the new UI feel less developer-first and more enterprise-pitchable. Make of that what you will. I think it's net positive, the old dashboard had real friction once you scaled past a couple of agents.
Made a full walkthrough on YouTube going through every tab if you want the visual version.
What's been your experience so far? Anyone hit weirdness on the migration?
