Dial gives developers a way to put an agent on a dedicated number for calls and messages.

Give the callback somewhere to land

An agent can know what it needs to say and still need a number to call from. When the person calls or texts back, the reply needs to reach the same workflow. Dial gives the agent a dedicated number for that exchange. [1][2]

Developers can connect voice and SMS to an agent through Dial. The number can handle outbound calls and messages as well as incoming replies. [1]

A cancellation on the dental calendar

Co-founder Gal Dayan suggested a dental waitlist as an example. A cancellation opens up a slot. An agent calls people on the list and can follow up by text if someone misses the call. Once someone confirms, the scheduling workflow can book the opening. [1][3]

The agent uses its own number while the practice keeps its main line for patient calls. A patient who returns the call or texts back can continue the same conversation. [3]

A phone line for software

Gal Dayan and Omri Ben Shoham founded Dial in 2025. The company joined a16z speedrun’s fourth cohort. Its product is for developers who want the agents they build to be reachable by phone. [1][2]

The bigger picture

An opening to fill can turn into a string of calls and replies. A dedicated line gives the workflow one place to pick up where it left off. [1][3]
