Retrium

Retrium is a long-running, retrospectives-only tool that emphasises guided five-phase facilitation, anonymous brainstorming, voting, a persistent action plan, and Team Radar health checks for distributed teams.

Retrium pitches itself as facilitated retrospectives that turn into a real discussion for scrum and agile teams, with a customer roster that leans heavily on engineering orgs (Adobe, Amazon, Eventbrite, GoDaddy, Etsy, Zapier).

"Your team can ensure psychological safety with private rooms, and everyone can share feedback openly because comments are anonymous."

The site foregrounds an opinionated five-phase flow — generation, grouping, voting, discussion, wrap-up rating — and positions Team Radar as the recurring pulse alongside the retro, with customisable spokes for safety, scrum values or remote work. Beyond engineering, Retrium markets itself to marketing, sales, HR and finance teams running any kind of recurring retro. Pricing is per team room rather than per seat, with unlimited users on every plan and an Enterprise tier aimed at organisations running 25+ teams.

Retrium is one of the older retro-only tools and it shows in the right ways: the facilitation flow is opinionated, the anonymous brainstorming is genuinely anonymous, and the persistent team-room action plan is a real differentiator over scratchpad-style retros. Team Radar is a credible health-check feature — anonymous 1-to-5 spoke ratings, customisable spokes, a Safety Check Radar variant, and sentiment tracked across cycles so you can see whether action items move the needle.

The gaps are sharper by mid-2026. The vendor's own changelog and blog show no shipped product activity in 2025 or 2026 — the most recent updates page is 2024 (Team Room Home refresh, guided tour, a Slack reinstall), and 2025 status entries are infrastructure maintenance, not features. Integrations haven't kept pace with the agile stack: Jira Cloud is solid, the Slack app is still labelled beta on Retrium's own integrations page, and there is no published Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence integration. There are no AI features at all on Retrium's site or trust center — no summary, clustering, action-item extraction, sentiment or trend insight — which is increasingly table stakes. Per-team-room pricing at $39/room/mo lands a typical small org of 3 teams × 8 users at $117/mo on the Team tier; SAML SSO sits on Business and SCIM is gated to Enterprise.

Best fit: a scrum master or coach who wants a clean, focused retro tool plus a recurring radar, lives mostly in Jira Cloud, and doesn't need AI or a Microsoft-stack footprint.
