Affinity.co Tech Stack

CRM for private capital with relationship intelligence and AI

Software Development San Francisco, California 201–500 employees Founded 2014 Privately Held

Affinity is a CRM built for dealmakers in private equity, venture capital, and investment banking. The stack—React, TypeScript, Rails, Postgres, AWS—is conventional, but the project list reveals a company pivoting toward AI: ambient intelligence for CRM, LLM-powered agents, and RAG adoption signal a shift from pure relationship tracking toward generative intelligence. Engineering-heavy hiring (9 of 23 open roles) with senior and director-level focus suggests they're scaling product velocity, not just headcount.
