The closest match in shape: an AI agent layer sold to enterprise CX teams on top of an existing help desk, with pricing behind a demo. Decagon's trust center is access-gated where Ada's certifications are readable without an account.
Same buyer, same outcome-priced pitch. Sierra publishes no pricing page at all (sierra.ai/pricing returns a 404), which is a stronger negative than Ada's demo gate.
The priced alternative to Ada's gate. Intercom publishes $0.99 per Fin resolution against Ada's unpublished conversation rate, and sells the help desk underneath rather than sitting on top of one.
Also an agent layer over an existing help desk, also billed per resolution. Forethought is Zendesk-owned, so the neutrality of the layer differs.
Bills per resolved ticket rather than per conversation, so a handoff to a human never bills. That is the opposite default to Ada's conversation model.
