Thena Pricing Explained (2026)
Thena starts at $29 per user on Starter, but the plan caps out at five users and 1,000 tickets a month — the jump to $79 Standard is a headcount decision, not a feature one.
| Plan | Price | Billing | What you get |
|---|---|---|---|
| Starter | $29/user/mo | per user, billed annually; up to 5 users, up to 1,000 tickets/month | Slack and email channels, AI ticket detection, AI summaries, AI tagging and AI assistant |
| Standard | $79/user/mo | per user, billed annually | Everything in Starter plus AI web chat, AI agent studio, MCP, APIs, AI auto-responses, AI co-pilot and AI-powered workflows |
| Enterprise | $119/user/mo | per user, billed annually | Everything in Standard plus custom AI agent deployments, Microsoft Teams, enterprise APIs, unlimited MCP and enterprise security |
The cheap tier has a volume ceiling, not a feature gate
Thena's Starter tier at $29 per user per month reads like a genuine small-team plan, and in feature terms it largely is — Slack and email channels, AI ticket detection, summaries, tagging and an AI assistant are all in it.
The constraint is elsewhere. Starter tops out at five users and 1,000 tickets a month. For a B2B support team that is roughly 45 tickets a working day, which a three-person team can clear comfortably. Cross it and the next stop is Standard at $79 — a 172% increase per seat driven purely by how many customers wrote in.
That is a different failure mode from most help desks, where growth is a seat-count problem. Here it is a demand problem, and demand is the thing you least control.
AI bundled is the structural argument
Thena's clearest pricing decision is that AI is not an add-on. Ticket detection, summaries, tagging and the assistant are in Starter; auto-responses, co-pilot and AI workflows are in Standard. Nothing is metered per resolution.
Set that against the obvious comparison:
| Product | Seat price (annual) | AI cost |
|---|---|---|
| Thena Standard | $79/user | Included |
| Pylon Professional | $89/seat | ~$50/seat add-on + agent usage |
| Unthread Pro | $75/agent | Included, 5-seat minimum |
On paper Pylon Professional and Thena Standard are ten dollars apart. With AI switched on they are roughly $139 against $79 — a gap of 76%, in Thena's favour, for a comparable Slack-native workflow.
The counter-argument is that bundled AI cannot be turned off to save money, and that metered models reward teams with low automation needs. That is real, but it applies to a shrinking set of buyers.
Annual-only changes the evaluation
There is no published monthly option at any tier. Starter for five seats is $1,740 committed up front.
For a product whose whole pitch is that it slots into how your team already works in Slack, that is a meaningful friction point. Run the trial hard before signing, and specifically test whether ticket auto-detection correctly identifies what counts as a ticket in your channels — that single behaviour determines whether the volume cap is comfortable or tight.
Teams support is an Enterprise paywall
Microsoft Teams sits in Enterprise at $119 per user. Slack sits in Starter at $29.
This is worth stating plainly because it is not a capability decision on the buyer's side. If your customers are enterprises standardised on Teams, your entry price for Thena is four times what a Slack-native startup pays for the same support workflow. That is a defensible commercial choice by Thena — Teams-first customers skew enterprise — but it means mid-market teams serving Teams customers should price alternatives carefully.
Model the three-year shape
A support team rarely stays still. The useful exercise is to price where you expect to be in eighteen months rather than where you are:
- Five users, under 1,000 tickets: $1,740/year on Starter
- Five users, 1,500 tickets: $4,740/year on Standard
- Ten users, any volume: $9,480/year on Standard
- Ten users on Teams: $14,280/year on Enterprise
The step from row one to row two costs $3,000 a year and is triggered by nothing you did — just more customers writing in. Budget for it rather than being surprised by it.
Who should buy it
B2B software teams running customer support in shared Slack channels who want AI included in the seat price rather than metered, and who are comfortable with an annual commitment. For that profile Thena is priced aggressively against Pylon and Unthread once AI is in the comparison.
It suits badly teams whose customers are on Microsoft Teams below enterprise scale, anyone who needs month-to-month billing, and small teams with high ticket volume — that combination hits Starter's ceiling immediately and pays Standard rates on a startup headcount. Check thena.ai for current tiers and confirm the ticket cap against your own last three months of volume.
What the pricing page doesn't show
- Starter's 1,000-ticket monthly ceiling is the real limit, not the 5-user cap. A three-person team handling 40 tickets a day crosses it inside a month and is pushed to Standard — a 172% per-seat increase driven by volume, not by any feature request.
- Every tier is billed annually. There is no published monthly option, so the entry commitment on Starter is $1,740 for five seats up front rather than a month-to-month trial of the paid product.
- Microsoft Teams support sits in Enterprise. Any organisation whose customers are on Teams rather than Slack is on the $119 tier from day one, regardless of team size — the channel your customers happen to use sets your price.
- The AI agent studio and MCP access arrive at Standard. If the reason you are buying Thena is to build custom AI agents, Starter is not an evaluation tier for that work, and the real entry price is $79.
- AI is bundled rather than metered, which is genuinely favourable — but it also means heavy AI usage cannot lower your seat count. The cost lever is headcount only, so teams that automate successfully still pay per human on the licence.
