We're building the infrastructure that lets AI agents handle email the way humans do—but faster, smarter, and 24/7.
It started with a simple observation. Voice agents were everywhere—handling customer service calls, booking appointments, answering questions. Companies poured billions into making AI sound human. The technology was impressive. You could call a pizza place and not realize you were talking to a machine.
Voice AI had arrived. The future was here.
But here's what nobody was talking about: voice is just the tip of the iceberg.
Behind every successful business, there's email. Millions of support tickets. Endless back-and-forth with customers. Order confirmations. Scheduling. Follow-ups. The unglamorous, invisible backbone of modern commerce.
Voice agents could answer a phone call, but what happened after? The customer still got an email confirmation. Still had to email for complex issues. Still waited days for a human to respond to their written queries.
Voice agents were solving 10% of the problem. The other 90%? Still stuck in overflowing inboxes.
We saw the trajectory clearly. Voice agents would need to do more than talk—they'd need to write. They'd need to handle the flood of emails that businesses deal with every single day.
But there was nothing built for this. Existing email APIs were designed for humans sending marketing campaigns. Help desk software assumed a person would read and respond. Nothing was built for AI-first, autonomous email handling.
We looked at each other and said: "This is what we need to build."
We built AIThreads from scratch to be the email infrastructure AI agents deserve. Not an afterthought. Not a retrofit. A purpose-built platform where AI can receive emails, understand context, compose intelligent responses, and handle conversations autonomously—with humans stepping in only when needed.
Today, we're making it possible for any developer to give their AI agent an email address in seconds. No DNS configuration. No SMTP headaches. Just pure, AI-first email infrastructure.
A world where AI handles the routine so humans can focus on what matters. Where no customer waits days for a response. Where email works for you, not against you.
A small team obsessed with making AI-powered email a reality.
Building the future of autonomous email, one API at a time.
Turning complex problems into elegant solutions.
We believe in rapid iteration. Real feedback from real users beats months of planning in a vacuum.
We build for developers. Clean APIs, great docs, and tools that just work. No enterprise sales-speak.
Everything we build assumes AI is the primary user. Human oversight is a feature, not the default.
We share our journey openly. Our shipping diaries, our decisions, our mistakes. Building in public.
