Software Development Toronto, Ontario 201–500 employees Founded 2016 Privately Held

CloudTalk operates a VoIP calling platform with AI-driven analytics, serving 5,000+ customers across 160+ countries. The stack reveals a mature, integrations-first architecture—HubSpot, Salesforce, Zendesk, plus WebRTC and Asterisk for telephony—paired with real-time infrastructure (Kafka, Redis, Elasticsearch). Active projects signal a sales-efficiency push: dual-track agile, PLG funnel ownership, AI voice agents, and AE training all point to a company in heavy product-led and sales-led motion simultaneously, while pain points around trial-to-paid conversion and time-to-first-value suggest bottlenecks in onboarding and early activation.
