Data Flow Patterns

Pattern 1: Standard Meeting

code

Meeting Ends
     ↓
Granola Processes (2 min)
     ↓
Zapier Trigger
     ↓
┌────────────────────┐
│ Parallel Actions   │
├────────────────────┤
│ → Slack notify     │
│ → Notion archive   │
│ → Linear tasks     │
└────────────────────┘

Pattern 2: Client Meeting

code

Meeting Ends (external attendee detected)
     ↓
Granola Processes
     ↓
Zapier Trigger + Filter
     ↓
┌────────────────────┐
│ CRM Path           │
├────────────────────┤
│ → HubSpot note     │
│ → Contact update   │
│ → Deal activity    │
│ → Follow-up task   │
└────────────────────┘
     +
┌────────────────────┐
│ Standard Path      │
├────────────────────┤
│ → Notion archive   │
│ → Slack notify     │
└────────────────────┘

Pattern 3: Executive Meeting

code

Corporate	Private	Executive only	exec-team
Engineering	Team	Engineering + PM	engineering
Sales	Team + CRM	Sales + Success	sales
HR	Confidential	HR only	hr-team

Integration Per Workspace

yaml

Corporate:
  - Notion (private database)
  - Slack (#exec-team private)
  - No CRM

Engineering:
  - Notion (engineering wiki)
  - Slack (#dev-meetings)
  - Linear (auto-tasks)
  - GitHub (PR references)

Sales:
  - Notion (sales playbook)
  - Slack (#sales-updates)
  - HubSpot (full sync)
  - Gong (call coaching)

HR:
  - Notion (confidential)
  - Slack (HR DMs only)
  - Greenhouse (if recruiting)

Security Architecture

Data Classification

Data Type	Classification	Handling
Transcripts	Confidential	Encrypted, access-controlled
Summaries	Internal	Team-shared
Action Items	Internal	Public within org
Attendee Names	PII	GDPR compliant

Encryption & Access

code

Data at Rest: AES-256
Data in Transit: TLS 1.3
Access Control: RBAC + SSO
Audit: Full logging enabled
Retention: Configurable per workspace

Scalability Considerations

Volume Planning

Team Size	Meetings/Month	Storage/Year	Plan
1-10	100-500	5-25 GB	Pro
10-50	500-2500	25-125 GB	Business
50-200	2500-10000	125-500 GB	Enterprise
200+	10000+	500+ GB	Enterprise+

Performance Budgets

Metric	Target	Measurement
Note availability	< 3 min	Post-meeting
Integration latency	< 1 min	Zapier to destination
Search response	< 500 ms	Within Granola
Export time	< 30 sec	For any meeting

Disaster Recovery

Backup Strategy

markdown

Primary: Granola cloud storage
Secondary: Nightly export to company storage
Tertiary: Weekly archive to cold storage

Recovery Points:
- RPO: 24 hours (daily export)
- RTO: 4 hours (restore from export)

Failover Procedures

markdown

If Granola unavailable:
1. Manual notes during meeting
2. Record with backup tool
3. Transcribe post-meeting
4. Manual upload when restored
