AgentPhone

Zero Index is excited to back AgentPhone (YC P26). AI agents can write code and manage workflows - but the moment they need to make a phone call or send a text, everything breaks. Developers end up duct-taping together telecom providers, voice APIs, compliance layers, and routing logic just to give an agent basic communication. AgentPhone's bet: if agents are doing real work, they need to work on the channels people actually use. One API provisions phone numbers with voice, SMS, iMessage, WhatsApp, and RCS built in. No vendor juggling, no compliance headaches. Just plug in and your agent can call and text in the real world. Early users have built AI recruiters that screen candidates over text, agents you can literally call to open a PR, and internal company brains that handle workflows over the phone. Meet Modi built AI agent infrastructure on WhatsApp at Meta, serving 280+ million businesses. Manav Modi led the Vogue app revamp at ROKMETRO, growing usage from ~100K to over 1M users. They're brothers who've been building together for two decades - and they've watched the biggest bottleneck in the agent stack shift from intelligence to connectivity. Telephony infrastructure that lets agents talk to the world. https://lnkd.in/geXR-YR4

AgentPhone in Forbes today. Voice and messaging built for AI agents: calls, SMS, iMessage, with real identity. The internet gave agents APIs. We're giving them a way to call and text. Link to the article in the comment.

I’m very excited to launch Linc! Our new AI intake assistant at LegalOS (YC W26). This project has been very special to me. Since starting at LegalOS, I’ve been looking for ways to streamline our initial intake process so we can cut down on multiple discovery calls. My solution was Linc! I’m absolutely not a technical founder, so it was especially fun to tackle my first coding project — and to have it be something that streamlines a part of my job and makes life a little easier for my clients. Shout out to Matthew Asir for encouraging me to take this on myself and for taking over once we needed to debug (lol). Also special shout out to Meet Modi and AgentPhone for making it super easy for us to set up the phone number. Linc helps people start their immigration journey over SMS or iMessage: answer a few questions, share the key details, and get routed toward the right attorney consultation faster. With Linc, you can get a rough qualification in just 10-15 minutes. It is built for founders, executives, operators, and highly skilled talent navigating O-1, H-1B, EB-1A, EB-2 NIW, L-1, TN, and more. The goal is simple: make immigration intake faster and clearer while still making sure every case gets to a real attorney. Linc is live now. Try it out here and please let me know what you think! https://lnkd.in/gX7f6zzS
