Affinity is a relationship-focused CRM built for private equity, venture capital, and investment banking. The stack signals a maturing platform: Salesforce + Outreach + Salesloft for core sales workflows, plus active adoption of Agentforce and RAG systems to automate deal workflows and data enrichment. Engineering-led hiring (11 of 26 roles) combined with projects in AI agents, API layers, and Kotlin Multiplatform development indicates a shift toward platform extensibility and intelligent automation—likely responding to pain points around long sales cycles and scaling beyond $100M ARR.
