Team messaging, video, and async communications platforms ranked by GrowthFriction Score (AUG v3 framework). Slack, Discord, Zoom, Loom scored across 7 factors. Slack (52) leads on team-level lock-in.
Slack (52) is the team-messaging fleet champion — category-defining + team-level switching cost. Discord (39) on community + voice + viral server invites. Zoom (29) on post-pandemic-plateau video. Loom (16) on async-video utility. The category compounds via team-adoption + per-seat enterprise contracts; video is the post-COVID maturity test.
Ranking — sorted by GrowthFriction Score
Slack
Fleet championGrowthFriction Score
51.84
team messaging (Salesforce-owned) · founded 2013 · confidence 0.8
Slack is the team-messaging fleet champion. AUG composite ~52, fleet-champion tier. The framework predicts this — Slack defined the team-messaging category and compounds via team-level lock-in. Microsoft Teams is the structural threat (free with Office 365 = -1 in Slack's long-term Acquisition advantage). AUG framework shows Slack still champion-tier despite competitive pressure. The lesson: category-defining + workflow-lock-in compound for 10+ years before competition can dislodge.

Discord
ThrivingGrowthFriction Score
38.88
community + voice chat (B2C with B2B reach) · founded 2015 · confidence 0.8
Discord is the community-fleet champion. AUG composite ~39, fleet-thriving tier (would be champion if Monetization compounded). The framework correctly shows Discord as quintuple-strong on engagement factors but capped by Monetization. The free-first strategy is intentional (network effects > per-user revenue) but the structural ceiling is monetization velocity. The lesson: consumer products can grow to $20B+ valuations on engagement compound even when monetization lags — but the monetization eventually has to come.

Zoom
HealthyGrowthFriction Score
29.03
video conferencing (post-pandemic plateau) · founded 2011 · confidence 0.8
Zoom is the post-COVID-plateau video product. AUG composite ~29, fleet-thriving tier. The 2020-2022 hyper-growth moment created a brand peak; the subsequent plateau is structural (Microsoft Teams + Google Meet bundle pressure, Slack Huddles fragmentation). AUG framework shows Zoom still in fleet-thriving tier — the underlying product strength remains. The lesson: even peak moments end; durable products survive by deepening other factors (Zoom Phone, Zoom Rooms, Zoom AI) when the original moment fades.

Loom

15.81
async video (Atlassian-owned) · founded 2016 · confidence 0.8
Loom is the async-video category leader. AUG composite ~16, healthy tier. The framework shows Loom healthy but capped — per-need usage limits Engagement/Retention compounding even with strong Activation. Post-Atlassian acquisition (2023, $975M), product velocity has slowed slightly. The lesson: per-need utility tools have a structural ceiling around composite 20 unless they integrate into daily workflows. Loom's Atlassian integration may be the unlock.

Methodology + confidence
Every audit is external-observation — scored from publicly visible signals only. Composite formula: AUG = 100 × Acq × Act × Eng × Ret × Adv × Mon × Perf ÷ 10⁷ — multiplicative, so a zero in any factor near-zeros the whole. See full scoring transparency.
