Your data, in your analytics stack

Affinity sends relationship and deal data directly to data shares like Snowflake. No exports. No pipelines to maintain. Live data in your analytics environment.

MCP: Affinity's relationship data in any AI tool

Affinity's hosted MCP server connects your CRM to Claude, ChatGPT, Gemini, and Copilot. A partner asking their AI assistant about a target gets back relationship history, deal context, and introduction paths from live Affinity data. No local setup. No engineering resources. The same permissions that govern what you see in the CRM apply to what your AI tools can access.

An API built for private capital firms

The Affinity API gives data teams full access to the relationship graph, deal records, contact data, and enrichment. Use it to sync Affinity with internal reporting tools, build custom deal intake flows, or connect portfolio monitoring systems that need live CRM data. Built around private capital's data model: funds, deals, LP relationships, and relationship strength scores.

Data shares for proprietary analytics stacks

For firms where relationship and deal data belongs in their analytics stack, Affinity delivers it directly to your data share. Your data team queries live Affinity data alongside fund performance, portfolio metrics, and market data in the same environment they already use. No scheduled exports. No stale snapshots. The relationship graph is in your warehouse when you need it.

One API layer. Your whole firm covered.

Most CRMs lock data inside a single interface. Affinity's API layer is built to move. The MCP server puts relationship intelligence into your AI tools. Affinity's API connects your CRM to the systems your firm runs. Data shares deliver it to the analytics layer where investment decisions get made. The same relationship graph, available everywhere your team works.
