SmartLineYour US Phone Number with a Personal Assistant
Your AI assistant answers every call, screens every caller, and sends you only what's worth your time.
The Thesis
Every call you answer costs you an hour of deep work. Every call you miss costs you a lead.
Founders were never meant to be receptionists. But every phone system ever built assumed you should answer.
We disagreed. The phone call is the last interruption-first communication tool left. Email became async. Slack became async. Meetings became optional. The phone never changed.
Until now.
SmartLine is the first business number built for founders who don't answer. It works from anywhere. Any country. Any timezone. Your US number follows you — Palma, Bangkok, Singapore, wherever you dock next.
Your AI PA answers every call. A world-class assistant that screens, qualifies, and handles — the way only the best human assistants ever could.
You get the summary. You decide what's worth your time.
You get the signal. Never the noise.
