Meet Penny

Your clients call.
Penny answers.

Reviews

What early users are saying.

We cut Monday morning admin from three hours to about twenty minutes. Penny handles the enquiries that used to pile up over the weekend before anyone even gets in.

Sarah Chen

Principal, Chen Advisory Group

I was paying for HubSpot, Calendly, Mailchimp, and a virtual receptionist. stack replaced all of them — and the AI actually understands my business.

David Marchetti

Director, Marchetti Financial Planning

My team actually uses this one. That's the highest praise I can give a tool. Setup took an afternoon and they were running on it by the next morning.

FAQ

Questions we actually get asked.

Most clients are live within an afternoon. You follow a few prompts during onboarding — connect your email, calendar, and phone number — and you'll land in the OS with everything configured. No data migration, no IT team, no technical knowledge needed.

Not on day one. stack integrates with the tools you already use — Xero, MYOB, Google Workspace, Microsoft 365, and more. Most clients find they naturally consolidate over time, but there's no hard cut-over required.

Yes. stack handles Australian phone numbers, operates within Australian business hours, and is supported by a team based in Melbourne. This isn't a US platform adapted for Australia — it was designed here, for here.

Your data belongs to you. It's stored securely in Australia, never used to train AI models, and we operate under Australian privacy law. Happy to walk you through our data handling on a call before you sign up.

We're offering founding member pricing to early waitlist sign-ups. You'll get preferential rates locked in before we open to the public. No credit card needed to join — just your email, and we'll follow up with an onboarding call.

Yes. stack works as a mobile web app with full feature parity — same visibility and control as the desktop experience. A native app for iOS and Android is on the roadmap.

Stop paying for 8 tools that don't talk to each other.

No credit card. No commitment. We'll reach out with a proper onboarding call when your spot opens.
