Every missed call is a lost customer. I build AI voice agents that answer your phone 24/7, qualify callers, book appointments, update your CRM and hand off to a person when it matters.
Three ways I can build your agent
Single prompt agent One well-structured prompt holds the agent's identity, rules, script and closing. I add custom functions, such as transferring the call to your team or firing a webhook to your CRM, and capture post-call fields like {{customer_name}}, {{customer_email}} and {{appointment_time}}. Fast to launch and ideal for focused use cases like a front desk or FAQ line.
Conversational flow agent A node-based flow where each step of the call (greeting, qualifying, booking, transfer, closing) is designed and controlled separately. This gives far more control over how the agent behaves, with the same custom functions and post-call data attached to the steps where they belong. Best for calls with branches, rules or compliance needs.
Persona-based agent The persona (name, tone, voice, speaking style) is built separately and attached to a conversational flow. Identity and script stay apart, so you can swap the persona for a different brand, campaign or language without rebuilding the logic.
