What we do

Agentic workflow design & build

Custom AI agents that automate intake, scheduling, and coordination — built around how your business actually operates.

SMS & messaging automation

Operational text-message systems with carrier-compliant opt-in and opt-out, wired into your workflow end to end.

Systems integration

Connecting calendars, telephony, and third-party data sources into one reliable, automated system.

Our work

Trip booking & flight-change notifications for private drivers

One of our systems helps private drivers manage their schedules end to end. It parses incoming ride requests, checks them against the driver's calendar for conflicts, and confirms bookings. It also monitors flight status and automatically texts the driver when a tracked flight is delayed or cancelled, so pickups can be adjusted in real time.

The messaging in this system is operational and goes only to the driver who uses it — see our SMS Terms for details.
