CallRail Tech Stack

AI-powered lead engagement platform for multi-channel attribution and sales automation

Software Development Atlanta, GA 201–500 employees Founded 2011 Privately Held

CallRail operates a lead engagement platform serving 220,000+ businesses with call, text, chat, and form attribution tied to marketing spend. The tech stack reveals a mobile-first architecture (iOS, Android, Swift, Kotlin) alongside enterprise sales tooling (Salesforce, Outreach, Gong, LeanData), while projects cluster heavily around voice AI—voice assist product development, onboarding, and demand expansion dominate the roadmap. The hiring mix (sales and product leading, engineering smaller) combined with pain points around Salesforce scaling and AI voice agent onboarding suggests CallRail is in a transition phase: moving from a traditional lead-capture vendor toward an AI-first platform while managing the operational complexity of a large installed base.
