A note on Ada's reported AWS Marketplace prices
Ada does not publish a rate card. A September 2026 review by Quiq, which competes with Ada, reports two AWS Marketplace listings: $33,000 for 12 months including 60,000 conversations, and a $35,000 annual conversation-volume package. We could not check those listings directly, so we label them unverified. Even if accurate, they are specific packages. Integrations, channels and professional services can add materially to the total. Get a quote from Ada.
Illustration: AI usage cost at 1,000 billable events a month
This is simple arithmetic on the published rates above. It covers AI usage only and ignores seats, included allowances and discounts. The units aren't identical (an outcome isn't the same as a session), so read this as a rough guide, not a like-for-like quote.
- HubSpot Customer Agent: 1,000 × 50 credits × $0.01 = $500 (before included credits)
- Freshdesk: 10 packs × $49 = $490 for 1,000 sessions, resolved or not
- Gorgias: $900 (annual) to $1,000 (monthly)
- Intercom Fin: 1,000 × $0.99 = $990
- Zendesk: $1,500 (committed) to $2,000 (pay-as-you-go) for resolutions beyond the allowance
- Salesforce Agentforce: 1,000 × $2 = $2,000 on the Conversations model
