# Subprocessor.info - Complete Documentation > Free database tracking subprocessor relationships across the SaaS ecosystem. Real-time visibility into which vendors your software providers use for infrastructure, AI, analytics, communications, payments, and security. --- ## Overview Subprocessor.info is a public intelligence resource that maps vendor relationships across the B2B SaaS ecosystem. When you use a SaaS product, that company typically uses dozens of other vendors (subprocessors) to deliver their service—cloud infrastructure, analytics, AI, communications, payments, and more. This site tracks and visualizes these relationships, making it easy to: - See which vendors a company relies on - Discover which companies use a specific vendor - Understand the interconnected SaaS ecosystem - Conduct vendor due diligence ### Why This Matters **For Security & Compliance**: GDPR Article 28 requires data controllers to know their processors' subprocessors. SOC 2 and other frameworks require vendor risk management. **For Procurement**: Before buying software, understanding their vendor dependencies helps assess risk concentration and data flows. **For Research**: The SaaS ecosystem is deeply interconnected. This data reveals patterns in infrastructure choices, AI adoption, and vendor preferences. --- ## Current Statistics - **17+ Companies Tracked** - **177+ Subprocessor Links** - **71+ Unique Vendors** - **7 Categories** - **37 AI Relationships Mapped** - **Average: 10.4 subprocessors per company** --- ## Companies Tracked ### Full Company List with Subprocessor Counts | Company | Subprocessors | Website | |---------|---------------|---------| | Figma | 21 | figma.com | | Vercel | 12 | vercel.com | | Stripe | 12 | stripe.com | | Rippling | 12 | rippling.com | | Atlassian | 10 | atlassian.com | | Intercom | 10 | intercom.com | | Notion | 9 | notion.so | | Linear | 9 | linear.app | | And more... | | | ### How Companies Are Selected Companies are added based on: - Public availability of subprocessor information - Relevance to B2B SaaS ecosystem - Quality of documentation (SOC 2, DPA, trust centers) --- ## Vendor Categories ### Infrastructure (57 vendors) Cloud and infrastructure providers including: - Amazon Web Services (AWS) - Google Cloud Platform - Microsoft Azure - Cloudflare - Fastly - And more... **Key Insight**: Cloudflare is the most commonly used infrastructure vendor across tracked companies. ### AI (37 vendors) Artificial intelligence and machine learning providers: - OpenAI - Anthropic - Google Vertex AI - And more... **Key Insight**: AI subprocessor relationships are growing rapidly as companies integrate LLMs and ML capabilities. ### Analytics (26 vendors) Data and analytics platforms: - Snowflake - Datadog - Amplitude - Segment - And more... ### Communications (21 vendors) Email, SMS, and messaging infrastructure: - Twilio - SendGrid - Mailgun - And more... **Key Insight**: The communications category is dominated by the Twilio ecosystem (Twilio, SendGrid). ### Customer Support Support and helpdesk platforms: - Zendesk - Intercom - And more... **Key Insight**: Zendesk and Intercom dominate the customer support subprocessor space. ### Payments Payment processing vendors: - Stripe - And more... ### Security Security and compliance vendors tracked across companies. --- ## Vendor Leaderboard Most common subprocessors across all tracked companies: | Rank | Vendor | Companies Using | |------|--------|-----------------| | 1 | Amazon Web Services | 13 | | 2 | Cloudflare | 11 | | 3 | Snowflake | 9 | | 4 | Twilio | 8 | | 5 | Datadog | 7 | | 6 | Sentry | 7 | | 7 | Intercom | 7 | | 8 | Zendesk | 7 | | ... | ... | ... | --- ## Data Sources All information is compiled from publicly available sources: ### Primary Sources - **Public Subprocessor Pages**: Many companies publish subprocessor lists on their websites - **SOC 2 Reports**: Type II reports often list key vendors - **DPA Documentation**: Data Processing Agreements frequently include subprocessor annexes - **Trust Center Pages**: Security and compliance portals ### Update Frequency Data is reviewed and updated regularly as companies publish new subprocessor information. ### Data Quality - Only publicly verifiable information is included - Sources are documented for each relationship - Outdated information is removed when detected --- ## Use Cases ### Security & Compliance Teams **Vendor Due Diligence** Before approving a new SaaS vendor, security teams need to understand the vendor's supply chain.
