Granola reference architecture

Granola Reference Architecture

Overview

Enterprise reference architecture for deploying Granola as the meeting intelligence platform across an organization. Covers the core capture pipeline, Zapier middleware routing, multi-workspace topology, security layers, and integration patterns for Slack, Notion, CRM, and task management.

Prerequisites

• Granola Enterprise plan ($35+/user/month)
• Zapier Professional or higher (for multi-step Zaps and Paths)
• Destination systems provisioned (Slack, Notion, CRM, Linear/Jira)
• IT architecture review completed

Step 2 — Folder-Based Routing Topology

Design folder structure to drive automated routing:

Folder	Trigger Type	Destinations	Permissions
Sales / Discovery	Auto	Slack #sales + HubSpot Deal + Follow-up Email	Sales team
Sales / Demo	Auto	Slack #sales + HubSpot Contact	Sales team
Engineering / Sprint	Auto	Slack #eng + Linear tasks + Notion wiki	Engineering
Engineering / Architecture	Auto	Slack #eng-arch + Notion ADR database	Senior engineers
Product / Customer Feedback	Auto	Slack #product + Notion feedback DB	Product team
Leadership / All-Hands	Auto	Slack #general + Google Drive archive	All
Leadership / Board	Manual only	Private Notion, no Slack	Executives only
HR / Interviews	Manual share	Greenhouse scorecard	Hiring managers
HR / 1-on-1s	None	Private, no automation	Individual

Step 3 — Multi-Workspace Topology

Organization (Enterprise)
├── Engineering Workspace
│   ├── Folders: Sprint, Architecture, Standup, Retro
│   ├── Integrations: Linear, Notion, Slack #engineering
│   └── Retention: 2 years notes, 90 days transcripts
│
├── Sales Workspace
│   ├── Folders: Discovery, Demo, Pipeline Review
│   ├── Integrations: HubSpot, Slack #sales, Gmail
│   └── Retention: 1 year notes, 90 days transcripts
│
├── Product Workspace
│   ├── Folders: Customer Feedback, Design Review, PRD
│   ├── Integrations: Notion, Linear, Slack #product
│   └── Retention: 2 years notes, 90 days transcripts
│
├── HR Workspace (Confidential)
│   ├── Folders: Interviews, 1-on-1s, Performance
│   ├── Integrations: Greenhouse (via Zapier)
│   ├── Retention: 30 days notes, 7 days transcripts
│   └── Restrictions: No external sharing, MFA required
│
└── Executive Workspace (Confidential)
    ├── Folders: Board, Strategy, M&A
    ├── Integrations: Private Notion only
    ├── Retention: Custom (legal hold capable)
    └── Restrictions: IP allowlist, 4-hour session timeout

Step 4 — Security Architecture

Authentication Layer:
  SSO (Okta/Azure AD) → SCIM provisioning → JIT workspace assignment

Data Protection:
  In Transit: TLS 1.3 (all API calls)
  At Rest: AES-256 (server-side storage)
  Local: FileVault/BitLocker (cache-v3.json encryption)

Access Control:
  Org Owner → Workspace Admin → Team Lead → Member → Viewer → Guest
  ↓
  SSO groups mapped to Granola roles per workspace

Data Classification:
  Confidential: HR, Legal, Board (restricted sharing, short retention)
  Internal: Engineering, Product (team sharing, standard retention)
  External-Facing: Sales, Customer Success (CRM sync allowed)

Compliance:
  SOC 2 Type 2: Certified (July 2025)
  GDPR: DPA available, data export/deletion supported
  AI Training: Opt-out enforced org-wide (Enterprise default)

Step 5 — Integration Data Flow Patterns

Pattern A: Standard Meeting (Parallel)

Note enhanced → Folder trigger fires
  ├─→ Slack notification (immediate)
  ├─→ Notion archive (immediate)
  └─→ Linear tasks (per action item)

Pattern B: Sales Meeting (Sequential)

Note enhanced → "Sales / Discovery" folder
  │
  ├─→ HubSpot: Find Contact by attendee email
  │     ├─→ Found: Log meeting note on Contact
  │     └─→ Not found: Create Contact, then log note
  │
  ├─→ ChatGPT: Generate BANT analysis + follow-up email
  │     └─→ Gmail: Create draft to external attendees
  │
  └─→ Slack: Post summary to #sales with deal context

Pattern C: Executive Meeting (Restricted)

Note enhanced → "Board" folder (no auto-trigger)
  │
  └─→ Manual share to private Notion database only
       └─→ Link expires in 7 days

Step 6 — Disaster Recovery & Data Export

Backup Strategy:
  Primary: Granola cloud storage (server-side, encrypted)
  Secondary: Local cache (cache-v3.json on each user's device)
  Tertiary: Nightly export to cloud storage (via Zapier + GCS/S3)

Recovery Procedures:
  1. User device loss: Re-authenticate, data syncs from server
  2. Integration outage: Zapier retries automatically; monitor Zap history
  3. Granola service outage: Manual notes during outage; capture resumes on recovery
  4. Data export request: Enterprise API bulk export or per-user Settings > Data > Export

Output

• Complete meeting ecosystem architecture documented
• Folder-based routing configured per department
• Multi-workspace topology deployed with appropriate isolation
• Security and compliance controls mapped to org requirements
• Disaster recovery plan established

Error Handling

Error	Cause	Fix
Notes routing to wrong destination	Filter logic error in Zapier Paths	Review path conditions, test with sample data
Cross-workspace access denied	Permission boundaries working correctly	Elevate user role or add to target workspace
Integration sync delay > 5 min	Zapier queue or destination rate limit	Add delay step, check destination API limits
Missing CRM updates for new contacts	Native integration doesn't auto-create	Add Zapier "Find or Create" step
Audit log gaps	Logging not enabled on workspace	Enable in Workspace Settings > Security
