🎯

Business use case

An AI voice/telephony workflow that handles calls — booking, qualifying or answering — without human agents, ideal for reception, scheduling and outbound campaigns.

📈

Phone handling is costly and hard to staff. AI voice agents answer every call instantly and scale infinitely — a fast-growing, high-value category.

💰

Market value

AI voice-agent platforms charge per-minute plus $99–$999/mo. Voice is one of the fastest-growing AI categories in 2025–2026.
