The constraint

What had to change

Manual dialing and follow-up capped how many prospects the team could reach, and missed inbound calls meant lost opportunities

The response

Architecture and delivery

AI voice agents on Twilio and Vapi that run outbound campaigns and answer inbound calls, with automated voicemail drops and SMS follow-ups

We built an AI calling platform for a marketing company on Twilio and Vapi: voice agents answer inbound calls and run outbound campaigns, hold natural conversations with prospects, drop voicemails when nobody picks up, and follow up over SMS. Call routing, campaign workflows, and conversation logs are managed centrally, so the team can launch and monitor calling campaigns without manual dialing — and no call or missed call goes unhandled.
