AI Agents & Chatbots Help Desk & Ticketing Knowledge Base & Self-Service
AI-powered support automation platform: helpdesk, knowledge base, and chatbots that answer from everywhere.
Organizations that want customer support and internal help desk automation from one vendor, across chat, voice, SMS and email, with agent assist, auto-QA and knowledge orchestration included, on Salesforce, Zendesk, ServiceNow, Slack or Genesys, with SOC 2, HIPAA and GDPR coverage.
You want to see a price before talking to sales: Capacity bills an annual platform fee plus usage and publishes no figures. Teams that only need a chat agent will be buying a much broader platform than they use.
Capacity is the consolidator of this category. Founded in St. Louis in 2017 by David Karandish and Chris Sims after Karandish's roughly $900 million exit as CEO of Answers.com, it has grown as much by acquisition as by code: eleven companies and counting, including Lucy, Linc, Textel, SmartAction, and in 2025 Call Criteria and Barcelona's Verbio Technologies. Each deal added a capability, and the result is a genuinely broad CX automation platform: AI agents across chat, voice, SMS, and email, real-time agent assist, automated QA and conversation intelligence, outbound campaigns, and a knowledge orchestration layer that answers from documents and apps across your stack.
The same platform serves customer support and internal helpdesk use cases, which suits organizations tired of buying those separately, and it automates workflows across integrations with Salesforce, Zendesk, ServiceNow, Slack, Microsoft Teams, Genesys, and many more. The company says it is profitable, past $60 million in annual recurring revenue, with over 20,000 organizations on the platform; 2025 brought another $92 million in funding to keep the acquisition engine running.
Pricing is a hybrid: an annual platform fee in three tiers plus usage, per response for chat and email, per minute for voice, per message for SMS. No dollar figures are published, so budget for a sales conversation.
Capacity fits buyers who want one throat to choke: a mid-size or larger organization consolidating support automation, internal helpdesk, and contact-center AI into a single vendor. Teams that prefer sharp best-of-breed point tools may find it broad rather than deep in places, but as a platform bet it is one of the more complete in the directory.
