We’re building CAIL.IO — your AI-powered phone operator. Our voice agents make calls on your behalf, handle hold music, ask questions, and return with clean summaries. Think LLMs + VoIP + calendar + real-world impact.
Hiring:
• AI Voice Agent Engineers, maybe someone has experience (LLM, TTS/STT)
• New Grads / Interns (agent logic, testing, QA, voice UX, fast learners)
Lots of voice tech + AI challenges. Small team, lots of ownership.
I'm building CAIL – an AI that makes and answers phone calls for you.
You type what needs to be done – it calls, talks, waits on hold, asks questions, and sends you a summary. Kind of like a voice assistant, but for actual phone calls.
Also built an AI voicemail agent – it can answer missed or declined calls, figure out what they wanted, book a meeting in your free calendar slot, or even mess with spammers if needed.
Started as a personal pain after moving to the US. Now works for both people and businesses. Built our own voice infra. iOS, Android for B2C, and web dashboard for B2B. Building full-time with my wife – just pushed the first version of the mobile app this week.
That's cool! I wondered about this recently -- I'd be pretty annoyed if an AI called me. I would most likely hang up immediately, regardless of what was said. Am I in the minority here? Is that feedback you've gotten before?
I do however think people would be more tolerant of an AI answering a phone call they made, I'm bullish on that half of the equation.
App in review right now in App Store & Google Play! I will send you a link to LinkedIn on release, but now you can try it in web ui on https://app.cail.io
But on the web platform you need to deal with forwarding on your own, in our app we have a bunch of instructions for each carrier.
