Open infrastructure
Relationship intelligence
infrastructure.
An API and MCP server that connects relationship context to any workflow. GitHub-native storage. User-controlled AI. No vendor lock-in.
Works with Claude Desktop, VS Code, Cursor, CRMs, and any MCP client
How it works
Capture, structure, connect
Meetings become structured data
Connect your calendar and Groupthink captures every conversation. Transcripts are automatically extracted into person-centric relationship records: commitments, context, history.
Data lives in your GitHub repo
Relationship data is stored as structured files in a GitHub repository you control. Version history, branch-level access, full portability. No proprietary database.
Any tool can query it
Use the REST API directly or connect via MCP. Claude Desktop, VS Code, Cursor, or your own tools can pull relationship context exactly when it is needed.
Capabilities
The intelligence layer
your tools are missing
API-first architecture
Every feature is an API endpoint. Build custom integrations, automate workflows, or query relationship data from any environment. REST with comprehensive documentation.
MCP protocol support
Native Model Context Protocol server. Claude Desktop, VS Code, Cursor, and any MCP-compatible client can access relationship intelligence without custom integration work.
GitHub-native storage
Relationship data is stored in your GitHub repository. You own it, you version it, you control access. Fork it, back it up, migrate it. No lock-in.
Person-centric intelligence
Data is organized around people, not meetings. Every interaction builds a richer profile: background, commitments, context, communication patterns.
Pre-meeting briefings
Automated briefings delivered before every meeting. Relationship history, open threads, and suggested talking points compiled from the full record.
User-controlled AI
AI retrieves and aggregates. You confirm significance. The system learns from your judgments, not the other way around. Pattern detection surfaces hypotheses with evidence, not conclusions.
Who it is for
Built for developers and teams
who want relationship context everywhere
Infrastructure that adapts to your stack, not the other way around.
AI-native teams
Pipe relationship context into Claude, GPT, or any LLM workflow via MCP. Your AI assistant knows the history before you ask.
Developer tools builders
Build CRM features, meeting prep, or relationship dashboards on top of the API. The intelligence layer is already built.
Sales and partnerships
Query relationship history from your existing CRM or deal flow tools. Every interaction is captured and queryable.
Investors and VCs
Relationship data across your entire portfolio, accessible from any tool. Track every founder and LP conversation automatically.
Consultants
Client relationship memory that travels with you. Access the full history from Claude Desktop, your project management tool, or the API.
Open source contributors
GitHub-native storage means your relationship data is just another repo. Inspect it, build on it, contribute tooling around it.
