Reimagining phone calling
with AI

Call Company designs human-sounding Voice-AI that answers in ~2 seconds, handles the routine, and hands off the rest with context. Our goal is simple: no missed calls, ever.

We’re building the fastest way for businesses to talk to people.

We believe in making AI accessible and valuable for everyone.

At One Second AI, our mission is to integrate AI into everyday life in ways that positively transform businesses and communities.

Our passion for developing AI solutions that deliver tangible value keeps us pushing boundaries, challenging the status quo and constantly setting higher standards for ourselves and our clients.

Together, we strive to build a better future, one intelligent solution at a time.

Book a Call

Finally. Phones that don’t ring out

Phones used to feel human. Then came phone trees, hold music, and missed calls. We built something better, an AI caller that sounds natural, answers instantly, and actually helps. We named it Callcompany to put calls back at the center.

What began as a “never miss a call” prototype is now a voice platform: picks up in ~2 seconds, handles routine requests, books and schedules, checks orders, and hands off tricky cases with a crisp summary, across 20+ languages and the tools you already use. Not a nicer bot, but a better way to run voice operations.

Today, teams from restaurants and retail to clinics, SaaS, and finance use Call Company to be reachable 24/7, cut tickets, and capture more bookings and orders, while people focus on work only humans can do. Our goal is simple: make business calls effortless, and a little magical, again.

Customer service that never goes unanswered

With our AI Phone Caller, every customer interaction becomes an opportunity. Capture more bookings, reservations, free up your team, and keep every conversation in your hands.

Humans stay in the loop

AI does the repetitive work; people do the meaningful work. Escalations are instant and informed.

Human-like automation

Natural tone, clear disclosures, and localized etiquette in 20+ languages. Useful before clever.

Privacy by design

Encryption, least-privilege access, audit logs, and GDPR from day one. HIPAA-eligible on request.

“At first, I thought this would just be an experiment, but the results exceeded all expectations… up and running quickly… refined so precisely I wouldn’t have believed it was even technically possible.”

Our Story

We started Call Company with a belief that voice is the most human interface, and that it deserved the same level of craft as great software. What began as a small prototype to eliminate missed calls became a full platform: real-time voice, knowledge you control, analytics, and integrations across the tools companies already use.
