One-Page Brief
Verdict
No as described. Go, small, as anonymous questions for Microsoft Teams.
A paid Slack bot for "one team ritual, pick later" is a real but small business. The best evidence is Abot: one developer, ~$4k MRR, ~100 paying teams from 5,000+ installs, $50k total profit over 5+ years, on ~5 hours a month (founder, June 2022). That is close to the ceiling for this kind of app, not the median. A later entrant in the same Slack niche, Anonymous Bot, has $891 MRR from 11 subscriptions after 6 years (Stripe-verified, TrustMRR).
Narrowed to anonymous questions on Microsoft Teams, the odds of reaching $1k MRR by month 24 are about 45% at ~15 hrs/week and 55% full-time. At $10k they are 6% and 10%. At $20k they are 2% and 4%. These are judgment estimates. See 01-verdict.md.
The five things that matter
- Most rituals are already free or native. Standups: Geekbot is free for up to 10 people, and Slack AI recaps now come with every paid Slack plan. Kudos: Microsoft's Praise is built into Teams. Birthdays: many free bots, and low willingness to pay. On-call handoffs: owned by PagerDuty, incident.io and Jira Service Management. Anonymous posting is the one ritual neither Slack nor Teams offers natively in channels, and people have paid for it for 8 years.
- Slack is the crowded version of this wedge. At least 6 anonymous apps are listed on the Slack Marketplace, at $7–120 a month. Since the 29 May 2025 terms change, the Marketplace is "the only appropriate channel" for commercial Slack apps. A listing needs 10 active installs before review, and the functional review takes up to 10 weeks.
- Teams is less crowded, but harder to get into. Teams channels have no anonymous posting. The anonymous options there are surveys (Forms, Polly, Team Survey) and in-event town-hall Q&A. But Teams admins can block third-party apps, so every sale needs IT approval.
- Installs are the limit, not code or margin. Hosting costs tens of dollars a month, and gross margin is ~93–95%. Abot converted ~2% of installs to paid. At that rate, $10k MRR needs ~7,000 installs. Nothing in the evidence shows a single-ritual Teams app getting that volume.
- Trust is the product. If the app ever stores who posted, one legal demand or breach ends the business. Build it so that you can't know.
Feature sort (headline)
- Table stakes: per-workspace pricing, trial, admin install, a moderation queue, basic anonymous polls.
- Differentiators: anonymous channel posts on Teams, the all-hands "question window" with upvotes and a ranked host view, provable anonymity (no identity stored), a one-click IT approval pack.
- Distractions: a multi-ritual bundle, standups, birthdays, a Slack-first launch, Google Chat, AI sentiment dashboards before $5k MRR.
- Liabilities: an admin "reveal identity" option, marketing as a whistleblowing channel, unmoderated posting, sending content to third-party AI.
Most likely cause of death
Distribution. The Teams Store brings a trickle of installs, IT admins block half of those, and the app stalls at 10–20 paying organisations. Early warning: fewer than 30 trials a month by month 6.
Next 90 days
Do: 10–15 calls with people who run all-hands at 100–2,000-person organisations on Teams. Run 3 paid pilot question windows by hand. Then build a thin Teams bot and submit it to the Store. Stop: choosing the ritual later. Pick anonymous questions now, and don't build for Slack first.
