The hybrid phone system for growing teams

Your team answers.
AI covers the rest.

Calls, texts and web chat land in one inbox your whole team works from — web or mobile. Whatever nobody picks up, the AI answers — then books the job, writes the summary and sends the follow-up.

Tenant maintenance calls, leasing inquiries and after-hours emergencies.

How To Get Started

Set up the assistant once — about 5 minutes. From the first call on, everything below happens on its own.

1
Set up your assistant

Scan your website to preset your assistant, then customize it further. Get a phone number and add your team if you want.

Someone picks up — or the AI does

That is the whole logic. No phone menu, no extensions, no voicemail box. The call rings your team; if nobody answers, the AI takes it.

1
It rings your team
Web and mobile, everyone at once
2
Nobody picks up, the AI answers
Never a voicemail beep, day or night
3
You get the recap

Every conversation comes back as a summary, a transcript, a task and an updated contact — ready the moment the call ends.

From there you can add automations, or connect your favorite tools to take action based on call outcomes.

Human + AI Communications Win

Every one of these is a moment where a phone system alone leaves voicemail, and an AI receptionist alone can't act.

Start free
After-hours emergencies

Leaks and lockouts answered at 2am, vendor dispatched, manager only woken if it's real.

Leasing overflow

Ad traffic answered on ring one, qualified, and booked into the right agent's calendar.

Storm-day surges

Forty simultaneous calls: unlimited concurrency, queued for your team by urgency.

Techs on the road

Mobile app on the business number — never a personal cell, always in the thread.

Renewals & rent questions

Answered from your lease terms at any hour, with anything unresolved left as a task.

Owner & vendor calls

Recorded, summarised and filed against the property, whoever took the call.

WORKS WITH YOUR STACK

Connects to the
tools you already use

Every call and text logs itself — contacts, summaries, outcomes and recordings. Calendars connect natively; everything else flows through Zapier or a direct webhook.
