What is Thena AI?

Thena's homepage: a Kanban-style support queue pulling in tickets from named accounts like PwC, Shell, ADP, and Sony.

Thena is a support platform built specifically for B2B teams, most often SaaS companies whose customers already live in shared Slack channels rather than emailing a support address. Founded in April 2022 by Ankit Saxena, Govind Kavaturi, Mike Molinet, and Unmukt Raizada, the company raised a $2.2 million pre-seed round from Pear VC and Tenacity Venture Capital, followed by a $5 million seed round from Lightspeed and First Round Capital, per its own press release, bringing disclosed funding to roughly $7.2 million. One third-party tracker lists a slightly higher total; we're using the figure the press release itself supports.

Thena's pricing page names Braze, Embrace, Tropic, Amplitude, Redpanda, and Oligo under a "Trusted by the best of B2B companies" banner, though it doesn't attach a case study or usage figure to any of them.

How does Thena's AI work?

The core mechanic is converting a Slack or Teams message into a trackable ticket without forcing the customer to leave the channel they're already in. A message in a shared Slack Connect channel, a Teams thread, an email, or a web chat form all land in the same underlying queue, tagged, routed, and (per Thena's own framing) handled by "purpose-built AI agents" that can "respond to customers, apply fields, create tickets, and escalate issues instantly."

That's the mechanism worth understanding: Thena isn't asking a B2B customer to adopt a new support portal. It's asking the vendor's support team to manage Slack-based conversations with the same triage, routing, and reporting discipline as a traditional help desk, using AI to close the gap between "a customer pinged us in Slack" and "someone tracked, tagged, and resolved that."

Agent Studio and MCP

On the Standard plan and above, Thena includes an AI agent studio for building and customizing AI agents, plus MCP (Model Context Protocol) support for connecting Thena's support data to external AI tools, including Claude, Cursor, Windsurf, and Raycast, per its own site. That MCP integration is a genuinely current mechanism: instead of only running Thena's own agents, a team can expose its support data to whatever AI tooling its engineers already use for other work.

Smart routing and account context

Thena centralizes account data across every channel a customer uses, so a Slack message and a follow-up email from the same company land against one account record rather than two disconnected threads. Auto-triage and role-based assignment route incoming messages to the right person or team, with customizable boards for tracking status. For a B2B support team managing dozens of Slack Connect channels simultaneously, that consolidation is the actual product, more than any single AI feature layered on top.

What features does Thena include?

• Omnichannel ticketing across Slack, Microsoft Teams, email, web chat and Discord, unified into one queue.
• AI ticket detection, summaries, and tagging, included on every plan including Starter.
• AI assistant and AI co-pilot for drafting responses (co-pilot ships from the Standard plan up).
• Agent Studio, for building custom AI agents (Standard plan and above).
• MCP support, connecting Thena's support data to external AI tools like Claude and Cursor.
• Account-level context, unifying a customer's messages across channels into one record.
• Knowledge management, private or public branded help centers.
• Broadcasting, multi-channel announcements with account-level targeting.

How much does Thena AI cost?

Thena's pricing page: Starter, Standard, and Enterprise, all billed annually per user.

Thena publishes real, checkable pricing on its own site, billed annually (re-checked 24 September 2026):

Thena's own pricing page states plainly that "AI is the baseline in all plans," meaning the AI ticket detection and tagging aren't an add-on tier, they ship even on Starter. Thena's homepage says "No credit card for free plan," but the pricing page itself doesn't list a free tier or its limits.

The gap worth noticing is that only Starter shows limits: 5 seats and 1,000 tickets a month. The Standard card says "Everything in Starter +" and lists features, not a higher ceiling, so it isn't clear from the page whether a team paying $79/user instead of $29/user also gets more seats or ticket volume. A team that mainly needs more headroom should ask Thena for the Standard and Enterprise limits in writing before it upgrades.

What reviewers say: Thena holds 4.9 out of 5 from 65 reviews on G2, checked 21 September 2026. Capterra lists Thena but carries no reviews, so G2 is the only real sample available.

What are Thena's pros and cons?

Pros

• Real, published, per-seat pricing, plus a free plan that needs no credit card.
• Genuine Slack- and Teams-native workflow, matching how B2B SaaS customers actually communicate with vendors today.
• MCP support lets a team plug Thena's data into AI tools it already uses elsewhere.
• AI ticket detection and tagging included on every paid tier, not gated to the top plan.

Cons

• Named customers (Braze, Amplitude, Redpanda, and others) appear as logos only, with no case study or usage figure attached to any of them.
• Only Starter publishes seat and ticket limits (5 seats, 1,000 tickets a month); Standard and Enterprise state none, so volume headroom above Starter needs a sales conversation.
• Narrowly built for B2B/SaaS support conducted primarily through Slack and Teams; a consumer support team gets little benefit from the core mechanism.
• The Enterprise card shows $119 without saying whether that is per user, so the cost at scale needs a quote to pin down.

Who is Thena AI best for?

Thena fits a B2B SaaS company whose customers already reach out through shared Slack Connect channels or Teams threads instead of a support portal, and whose support team needs those conversations tracked and routed with the same discipline as email tickets. The AI ticket detection and tagging, included even on Starter, mean a small team can get real triage automation without buying into the top tier.

It's a weaker fit for a consumer-facing support team, since the entire mechanism is built around Slack- and Teams-based B2B relationships rather than a customer-facing chat widget or a traditional email queue. It's also a mismatch for a team already committed to Zendesk, Freshdesk, or another established help desk that mainly wants AI layered on top of tickets already flowing through that system, rather than a new platform to manage Slack-based support separately.

How does Thena AI compare with Pylon and Macha?

Thena and Macha aren't really solving the same problem. Thena is a full support platform built around Slack- and Teams-native conversations; Macha is an AI agent layer that runs on top of a help desk a team already has, like Zendesk, Freshdesk, Gorgias, Front, HubSpot or Intercom. Macha fits teams that have already standardized on one of those help desks and want the tickets flowing through it automated, instead of adopting a new platform to manage support separately. Macha is also done for you: the Macha team analyzes your past tickets, builds the knowledge base and the agent on your help desk, and runs it in safe mode until the drafts are right. The price, about $0.40 a ticket, includes that setup and a dedicated success manager who handles your changes. Thena fits a B2B team whose actual support conversation happens in Slack and needs that turned into trackable, AI-assisted tickets in the first place. For a closer comparison within the Slack-native category, Pylon covers similar ground with its own take on B2B, channel-based support.

The two products Thena is most often compared against both have full guides here: Pylon, the closest direct competitor for B2B, channel-based support, and Unthread, which does the Slack-to-ticket job with less account tooling around it.
