Scoring Card

Dimension	Score	Rationale
Pain	3/5	Growth teams live in Slack — important events are buried in dashboards nobody checks
Revenue	3/5	Increases platform stickiness and perceived value for team-plan customers
Build	4/5	Straightforward Slack app with event routing — well-documented API
Moat	2/5	Slack integrations are common, but GrowthOS event bus makes routing richer
Total	12/20

Classification

Vitamin

Vitamin

Slack integration is a quality-of-life feature that makes GrowthOS data visible where growth teams actually work. It reduces dashboard fatigue and enables faster response to critical events like NPS detractors and churn signals.

---

The Pain It Kills

“A user gave us NPS 2 on Monday. We didn’t see it until the weekly dashboard review on Friday. By then, they had churned.”

• Growth teams live in Slack — important events are buried in dashboards nobody checks daily.
• By the time someone notices a detractor NPS score, churn signal, or campaign failure, it is too late to act.
• Custom webhook integrations with Zapier are fragile and limited in formatting.
• No way to route different event types to different Slack channels without custom code.

---

What It Does

• Slack app installation — standard OAuth-based Slack app with channel permissions.
• Event-to-channel routing — configurable rules: new signup → #growth, NPS detractor → #support, referral conversion → #wins, billing event → #revenue.
• Configurable alert templates — rich Slack message formatting with actionable context (contact name, score, event details, direct link to GrowthOS dashboard).
• Channel management — select which Slack channels receive which event types.
• Notification preferences — per-user and per-team notification settings to prevent alert fatigue.

Competition & What We Replace

Tool	Pricing	Limitation
Custom webhook + Zapier	$20-50/mo	Fragile, limited formatting, manual setup per event
Native tool integrations	Varies	Each tool (PostHog, Stripe, etc.) sends to Slack separately — no unified view
Datadog/PagerDuty	$15+/host/mo	Infrastructure-focused, not growth-event-focused

GrowthOS Slack integration provides a unified stream of growth events — one app, one configuration, all events routed intelligently.

Moat & Defensibility

Event bus breadth (2/5).

• Every GrowthOS module emits events to the event bus — Slack integration can route any of them.
• Unified event format means consistent, rich Slack messages regardless of source module.
• As new modules are added, they automatically become available for Slack routing.
• The combination of breadth (all growth events) and routing (per-channel configuration) is unique.

Interoperability Advantage

What Ships

• Slack app installation — OAuth-based with channel permissions
• Event-to-channel routing — configurable rules for event → channel mapping
• Configurable alert templates — rich message formatting with context and action links
• Channel management — UI for selecting channels and event types
• Notification preferences — per-user and per-team alert settings
• Event filtering — threshold-based alerts (e.g., only alert on NPS ≤ 3, not all NPS submissions)

---

What Does NOT Ship

• Slack chatbot (no conversational AI in Slack)
• Slack-based workflows (no triggering GrowthOS actions from Slack)
• Bi-directional Slack commands (no /growthos slash commands)
• Microsoft Teams integration (Slack only in v1)

---

Build vs Buy

BUILD.

Slack app development is well-documented and straightforward. The unique value is the connection to the GrowthOS event bus, which provides richer event data and more flexible routing than any generic webhook integration.

Estimated effort: 2-3 weeks.

Dependencies

Dependency	Why
None	Standalone integration — connects to the GrowthOS event bus which exists from Phase 1.
