NimbleRetro
3.6Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs structured, time-bound retros through Icebreaker, Ideation, Grouping, Voting, and Root Cause Analysis stages, with anonymous input, action item tracking, and a 5-Why root cause workflow. Native iOS and Android apps complement the web product, and action items convert directly into Nimble workitems (user stories and cards).

NimbleRetro — pros
- + Structured 5-Why root cause workflow built into the retro flow
- + Anonymous input and time-bound stages keep retros focused
- + Native iOS and Android apps for mobile participation
- + NimbleWork runs an annual SOC 2 Type II audit and an ISO/IEC 27001:2022 audit, with SAMLv2/ADFSv3 SSO at the platform level
- + Action items convert directly into Nimble work items, so follow-up lands in the same backlog the team already works from
NimbleRetro — cons
- − Only four templates, and custom templates cap out at four columns
- − No SCIM provisioning or audit logs documented; SSO and the SOC 2 / ISO 27001 attestations sit at the NimbleWork platform level, not the retro module
- − Comparison pages tick 'Generative AI' for NimbleRetro, but no retro AI (clustering, summaries, sentiment) is documented — NimbleWork's AI Agents are a separately licensed add-on aimed at Nimble cards and analytics
- − No documented export of a retro board in any format
- − Thin direct-integration story for the agile stack — no documented Jira, GitHub, Linear, or Azure DevOps hooks for the retro module
- − Participants are limited to members of the Nimble project the retro is created from
- − NimbleRetro's own pricing page is demo-gated; the only published rate card is the Nimble suite's ($10/user/mo Team, $26/user/mo Business)
Retrium — pros
- + Battle-tested five-phase guided facilitation flow
- + Anonymous brainstorming and grouping by design
- + Persistent team-room action plan that carries forward between retros
- + Team Radar health check — up to seven customisable spokes, anonymous 1–5 scoring
- + Per-team-room pricing with unlimited users on every plan
Retrium — cons
- − No free plan — 30-day trial only, and the Fishbone technique stays paid-only during it
- − Integrations stop at Jira Cloud and a <em>still-beta</em> Slack app — no Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence
- − <strong>No AI features at all</strong> — no summary, clustering, action-item extraction or sentiment
- − The only API is an Enterprise-gated SCIM 2.0 user-provisioning endpoint; no webhooks, and export stops at CSV and TXT
- − No published product updates since <strong>August 2024</strong> — the help centre's yearly updates series ends at 2024
