Key takeaways for Vellum Assistant

Where is it heading?

  • The broken registration flow prevents new users from entering the product, which compounds the negative sentiment already present in recent reviews.
  • A slow release cadence of one update in 26 days suggests the team is not responding quickly enough to critical user-reported bugs.
