I started in engineering, spent more than three years running operations and finance for a creator company, and now design, build and run my own products. I also help creators and founder-led businesses run theirs.

Building now: HexStep, Better Check-In and Stagebook.

Better Check-In

A front desk that checks people in by itself, and knows when to call staff.

For studios that book on Wix. Live on the Wix App Market. See the listing

  1. A client walks up to the tablet and types their name.

    Today's bookings come straight from the studio's Wix calendar.

  2. It checks the booking, the payment and the waiver.

    Three things the front desk would otherwise check by hand.

  3. If everything is in order, they're checked in.

    One tap, and the booking is marked as attended.

  4. If something is missing, it sends them to staff, and shows staff why.

    Here, a payment hasn't been collected. Staff see the reason and decide.

Kiosk: a client types their name to find today's booking Kiosk: Ava T. is ready to check in. Booking confirmed, payment complete, waiver complete Kiosk: you're checked in Kiosk: Noah K., please see staff, booking needs attention
Staff view: Noah Kim needs staff because the payment was not collected
What staff see

Screens from Better Check-In with demo bookings. The tablet frame is an illustration.
