Cresta operates as a real-time agent-assist layer designed to enhance human performance in live customer service interactions, particularly in enterprise contact centers with 100+ agents, though its capabilities can benefit smaller building code consulting teams seeking to improve consultation quality and efficiency. According to their website and third-party reporting from early 2026, Cresta listens to live customer calls, surfaces real-time prompts to agents, auto-scores 100% of conversations, and runs automated coaching workflows—helping consultants provide more accurate, consistent, and empathetic responses during technical discussions about building codes or compliance requirements. The platform integrates with existing CCaaS infrastructure such as Genesys or Five9, functioning as an AI overlay that augments rather than replaces human agents.
