1.Favicon of Sierra

Sierra

Direct replacement
Outcome-priced AI agent with no published rate
Sales-gated

The closest match on shape and on silence. Both are enterprise AI agent platforms with no pricing page (sierra.ai/pricing also returns 404) and a pricing philosophy published only as a blog post. Sierra leads with outcomes where Decagon leads with conversations, and Sierra rules out seats outright where Decagon never addresses them.

2.Favicon of Lorikeet

Lorikeet

Direct replacement
AI support agent billed from a prepaid credit pool
$1,500/mo·+$0.25 per credit

The counterexample. Lorikeet publishes a full rate card, credit rates per channel and worked examples at lorikeetcx.ai/pricing, plus a machine-readable mirror. Decagon publishes no figure of any kind.

3.Favicon of Intercom

Intercom

Direct replacement
Support platform with per-outcome AI billing
$39/seat/mo·+$0.99 per AI resolution

Fin is sold standalone onto an existing help desk, the same posture Decagon takes. Intercom publishes $0.99 per outcome, which handoffs bill and which do not, and a reopen refund rule. Decagon publishes none of those.

4.Favicon of Ada

Ada

Direct replacement
Sales-gated AI agent billed per conversation
Sales-gated

Enterprise AI agent competitor that also gates its price behind sales, but documents a four-role seat model where Decagon names no roles and no seat concept at all.

5.Favicon of Forethought

Forethought

Partial replacement
AI agents for any help desk, priced by outcome
Sales-gated

Overlaps on autonomous resolution over an existing help desk, at a smaller and less enterprise-weighted deployment size.
