NimbleRetro
3.8Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs a time-boxed retro through Icebreaker, Ideate, Group, Vote, Discuss and Feedback stages, ending in a 5-Why root cause drill-down on whatever the team voted up. Action items created in the Discuss stage convert directly into Nimble work items (user stories, cards) in the project the retro was created from. There is no separate purchase — Retrospectives ship to every Public SaaS Nimble account by default.

Retrium
5.0Guided retrospectives and Team Radars for scrum and agile teams
Retrium is a long-running, retrospectives-only tool built around a guided five-phase facilitation flow, anonymous brainstorming, dot voting, a persistent action plan, and Team Radar health checks. Since August 2026 the vendor has also run Retrium Next, a separate free open beta that rebuilds the retro around an AI co-facilitator.

NimbleRetro — pros
- + 5-Why root cause analysis is a <em>built-in retro stage</em>, not an afterthought — almost no other retro tool ships one
- + Anonymous voting plus a facilitator-set timer on every stage keeps a 60-minute retro on the rails
- + Action items convert directly into Nimble work items, so follow-up lands in the same backlog the team already works from
- + Included by default in every Public SaaS Nimble account — no separate purchase, no tier upgrade, available to all user roles
- + NimbleWork runs annual SOC 2 Type II and ISO/IEC 27001:2022 audits, supports SAMLv2/ADFSv3 SSO, and publishes a separate EU data region
NimbleRetro — cons
- − The dedicated NimbleRetro iOS and Android apps have been delisted from both the App Store and Google Play, while the product pages still advertise them
- − No health checks, no recurring retros, no async mode, and no documented export of a retro board in any format
- − The platform surface — REST API, outgoing webhooks and the new Nimble MCP server — reaches Nimble cards only; none of it touches a retro, and no AI runs on retro data despite the Retrium comparison page ticking <em>Generative AI</em>
- − Participants are limited to members of the Nimble project the retro was created from, and the module is unavailable outside Public SaaS
- − No rate card: the only NimbleRetro-specific price NimbleWork publishes ($15/mo for up to 20 users) sits on a blog post, and the retro 'pricing' page is a product page with a demo form
Retrium — pros
- + Battle-tested five-phase guided facilitation flow — think, group, vote, discuss, wrap-up
- + Anonymous brainstorming and grouping by design, with a documented Fishbone root-cause format
- + Persistent team-room action plan that carries forward between retros
- + Team Radar health check — ten prebuilt radars plus a custom-spoke template, anonymous 1–5 scoring
- + Per-team-room pricing at <strong>$39/mo</strong> with unlimited users on every plan
Retrium — cons
- − No free plan — 30-day trial only, and the Fishbone technique and SSO are excluded from it
- − Integrations stop at Jira Cloud and a <em>still-beta</em> Slack app — no Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence
- − AI exists only in <strong>Retrium Next</strong>, a separate free open beta with no data migration, no uptime commitment and no pricing yet — the product you actually pay for has none
- − The only API is an Enterprise-gated SCIM 2.0 user-provisioning endpoint; no webhooks, and export stops at CSV, TXT and send-to-Jira
- − The shipping product has published no release notes since <strong>August 2024</strong>, and the Continuous Improvement Journey beta closed in December 2023
