Mixdesk vs Thena: Which Is Better in 2026?

Mixdesk is an AI customer support platform for teams managing customer conversations across connected messaging channels, website chat and email. Its shared inbox helps support and sales teams work with conversations in one place. Knowledge-based AI replies can address routine questions, while human handoff lets team members take over when a conversation needs personal attention.
The platform is designed for customer-facing teams that want to combine automated responses with human service. Teams should check supported channels and setup requirements in the official documentation before connecting their workflows.
Mixdesk offers free and paid plans. The Free plan does not include AI Agents. AI availability, usage allowances and other limits depend on the selected plan. Current pricing is available at https://mixdesk.com/pricing and product documentation at https://mixdesk.com/help/en/.

Thena is a customer support and operations platform built for B2B companies that support their customers through shared Slack and Microsoft Teams channels. As more B2B relationships move communication into Slack Connect and Teams channels, support requests, questions and issues increasingly come through chat rather than traditional ticketing — and managing that effectively is hard. Thena turns these conversations into a structured, trackable, AI-assisted support workflow, so nothing gets missed and teams can deliver excellent, organized support where their customers actually talk to them.

The platform sits on top of your shared channels and helps you manage them like a real support operation: detecting and tracking requests, assigning and prioritizing them, ensuring timely responses, and giving visibility into what's happening across all your customer channels. It uses AI to help triage and respond, surface insights, and reduce the manual overhead of keeping up with many conversations. By bringing ticketing-like structure and intelligence to chat-based support, Thena solves a real problem for B2B teams whose customers expect to reach them in Slack or Teams but who need the accountability and tracking of a proper support system.

Thena is aimed at B2B SaaS companies and others whose customer relationships and support happen heavily in shared messaging channels, and who want to manage that professionally rather than letting requests slip through informal chats. It connects to the broader support and CRM stack so customer context and data flow where they're needed. As B2B communication continues shifting into Slack and Teams, and as AI makes managing those conversations smarter, platforms that bring order and intelligence to channel-based support are increasingly valuable. For B2B companies that support customers in Slack or Teams and want a structured, AI-assisted way to manage it, Thena offers a focused, modern and genuinely useful solution.
