Thena vs Intercom (2026)

TL;DR

• Where do your customers ask for help? Shared Slack channels point to Thena. Your own web or mobile app points to Intercom.
• Thena bundles AI into the seat: $29 Starter (5 users, 1,000 tickets/month cap), $79 Standard, $119 Enterprise, annual only.
• Intercom splits the bill in two: $29/$85/$132 per seat, plus Fin at $0.99 per resolved issue. Volume, not headcount, sets the invoice.
• Thena is the newer, narrower product. Intercom is the more complete one and charges accordingly.

Channel is the whole decision

Thena was built on the observation that B2B software companies increasingly support customers in shared Slack Connect channels, and that those conversations have no ticket structure, no SLA, and no reporting. It converts Slack messages into tracked tickets automatically, pulls email and web chat into the same queue, and groups everything by account so you see the whole relationship rather than isolated threads.

Intercom came from the opposite side. Its native habitat is the messenger embedded in your product, where an end user clicks a bubble and gets help without leaving the page. Around that it has grown ticketing, a help center, proactive in-app messaging, and omnichannel coverage across email, SMS, WhatsApp, and social.

Try to force either into the other's shape and you get a poor product. Intercom has no meaningful answer for a customer who only ever talks to you in a shared Slack channel. Thena has no in-product messenger, no product tours, no lifecycle messaging triggered on usage data.

Pricing

Thena publishes $29, $79, and $119 per user per month, annual billing only, with no month-to-month option at any tier. Starter is capped at five users and 1,000 tickets a month. The AI — ticket detection, summaries, tagging, assistant at Starter; auto-responses, co-pilot, agent studio, workflows at Standard — is bundled. Nothing is metered.

Intercom publishes $29 (Essential), $85 (Advanced), and $132 (Expert) per seat annually, with monthly options at $39/$99/$139. Fin, the AI agent, is available on every plan but charged at $0.99 per resolution. Copilot, the agent-facing AI, is a separate $29/agent/month. Proactive Support Plus is $99/month for 500 sent messages; advanced analytics is another $99/month capped at 1,000 conversations.

The structural contrast matters more than the numbers. Thena's cost lever is headcount and, on Starter, ticket volume. Intercom's is resolution volume — a six-seat Advanced team pays $510 in seats and anywhere from $495 to $4,950 in Fin depending purely on how much AI does. One model is predictable; the other is outcome-linked but hard to forecast a year out.

AI economics run in opposite directions

Bundling AI removes the meter, so nobody at Thena hesitates before switching something on. The flip side: successful automation cannot lower your bill, because the only lever is human seats.

Intercom's counter is that you should pay for outcomes, and $0.99 per resolved issue is genuinely honest — escalations to a human are not billed. The flip side is that teams often buy both meters. Copilot makes agents faster while Fin reduces the tickets reaching agents at all; running both is defensible at high volume and wasteful at low.

The practical test: if a large slice of your inbound is repetitive and self-servable, Intercom's model can undercut the agents you would otherwise hire. If your inbound is a modest volume of hard, account-specific questions, per-resolution pricing gives you nothing.

Maturity and the honest gaps

Intercom is the more finished platform, and in places clearly best in class — the omnichannel inbox and in-product messenger especially. It also carries the costs of size: real setup time, a lot of surface small teams never touch, and add-ons whose caps (500 outbound messages, 1,000 analyzed conversations) run out faster than the price suggests.

Thena is younger, and its own positioning admits enterprise security features are still maturing. Two constraints matter. Microsoft Teams support sits at Enterprise, $119 per user, so customers standardized on Teams quadruple your entry price for the same workflow. And Starter's 1,000-ticket ceiling is a demand limit, not a headcount limit: a three-person team clearing 45 tickets a day crosses it inside a month and lands on $79 — a 172% per-seat increase triggered by nothing they chose.

Account context versus user context

Thena tracks at the account level, grouping tickets by company so a lean team supporting many enterprise logos sees the whole relationship. That is the right unit for B2B, where the customer is an organization with several people writing in. Intercom tracks at the user level and enriches it with product behavior — what the person did, where they got stuck, what lifecycle stage they are in. That is the right unit for product-led SaaS, where the best support is often a message sent before anyone asks. Neither is superior in the abstract; they describe different businesses.

Who should pick what

• B2B SaaS supporting customers in Slack Connect channels → Thena. Nothing in Intercom addresses this.
• Product-led software with in-app support and high self-serve volume → Intercom, with Fin turned on.
• Teams that need firm budget numbers twelve months out → Thena. Bundled AI means the invoice is seats times price.
• Companies whose customers live in Microsoft Teams → check Thena Enterprise pricing before assuming it is affordable; Intercom does not serve this pattern either.
• Qualifying early-stage startups → Intercom's Early Stage program advertises up to 93% off plus a year of Fin, which distorts the comparison for year one only.
• Low-volume, high-complexity support → Thena. Intercom's AI meter returns nothing when every ticket needs a human.

Bottom line

Not a close feature fight, because the two barely overlap. Thena is a Slack-first B2B desk with predictable bundled-AI pricing, an annual-only commitment, and a Starter tier whose ticket ceiling deserves checking against your last three months of volume. Intercom is a mature omnichannel platform whose messenger and AI agent are among the best available, sold with a variable meter that rewards deflection and punishes low-volume complexity. Pick by where your customers already talk to you, then price the tier that actually holds what you need — Standard for Thena if you want the automation layer, Advanced for Intercom if you route to more than one team.
