What each is best for
Beam AI is worth it if… enterprises that want to deploy AI agents for internal workflows (procurement, IT ops, HR) rather than customer support. Different buyer than Ada or Decagon — internal ops leader, not head of CX.
Sierra is worth it if… Sierra is only worth engaging with if you're a mid-market or enterprise support org running a serious evaluation of autonomous AI agents — the co-founders' pedigree (Bret Taylor ex-Salesforce COO) opens doors that other startups can't. Deal size $200K-1M+/year.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
