Built with Harper Voice
A growing roster of products with diverse use cases all use Harper Voice to make phone calls for their users. If automatically making a phone call for your users can benefit your product, it belongs here too.

- →Calls to elected representatives' offices
- →Healthcare advocacy calls
- →Tax & fiscal policy calls
- →Local zoning & land-use issues
- →Recurring weekly advocacy campaigns
Call for Action
Call for Action places calls to elected representatives and government offices on a constituent's behalf, navigating the hold times, phone trees, and bureaucracy so their message actually gets heard. Calls go out from the user's own number, so they land as genuine constituent contact. Harper Voice handles the caller ID, compliance rules, and agent guardrails that keep every advocacy call within bounds at scale.

- →Doctor & dentist appointment scheduling
- →Insurance billing disputes
- →Subscription cancellations
- →Reservation follow-ups
- →One-off administrative calls
Harper Edison
Harper Edison is a general-purpose assistant for any phone call you'd rather not make. Ask it in plain language to reschedule a dentist appointment, dispute a bill, or chase down a contractor, and it places the call, waits through the hold music, sees the conversation through, and hands back a clean summary. The interface is just a chat. Underneath, Harper Voice handles the dialing, retries, voicemail, and structured outcomes, so the user never has to pick up the phone.
- →HVAC service scheduling
- →Plumber & electrician bookings
- →Gutter & exterior maintenance
- →Vendor follow-up & confirmation
- →Service cancellation & rescheduling
Homewise
Homewise tracks every maintenance task a home needs and schedules the right vendors automatically. When a task is due, it calls the vendor, negotiates a time that works, and books it on the homeowner's calendar. That real-time back-and-forth runs on Harper Voice's live negotiation and calendar tool calls, with no telephony stack to build.
- →Vendor availability & booking
- →Venue coordination calls
- →Day-of logistics confirmation
- →Supplier follow-up & reminders
- →Post-event wrap & reconciliation
Run the Show
Run the Show is a production coordination platform for live events, where every event hides a web of vendor calls: caterers, AV teams, venues, and logistics. It handles all of them automatically, so the event team never picks up a phone. Because events are time-sensitive, Harper Voice's priority queue and compliance-aware retries make sure critical calls happen the moment they need to.

if calls were easy?
Every one of these products started with a feature that needed a phone call. Harper Voice is what made it buildable.
