The Story
Your career shouldn't be a black box.
ShowCal wasn't dreamed up in an office. I built it with Rusty after years on set, tired of running our own working lives through other people.
Sc. 01 · Set life
I came up on the monitor cart.
I studied computer science in Indiana and paid for it running a pizza business. Then a semester in Cape Town rearranged everything. I stayed, and spent the better part of a decade as an aerial cinematographer and drone operator — across Africa and the Middle East, on films like Black Panther and Maze Runner, and more car commercials than I can count. It was on the helicopter unit of Tomb Raider that aerial clicked for me: the camera in the air, the whole set laid out below, every move timed to the minute.
Freelance life is a strange business. The work is glorious. The admin is a nightmare. My availability lived in my head and five group texts, and the only way anyone knew whether I was free was to call and ask.
Sc. 02 · What we built
Rusty, and everything before ShowCal.
Rusty Ruthven and I kept ending up on the same jobs, and eventually in the same businesses. He's a DIT who built Monstrum into one of the biggest post-production crews in South Africa — the people who keep a production's footage alive all the way from the set to the edit.
Between us we built a few things. Film Gear, the continent's first online store for film equipment, which grew 300% in the middle of COVID (we closed it in 2024 to put everything into ShowCal). Kelvin Corner, a coworking space we made out of an old secondhand-furniture shop in Cape Town, where half the international crews passing through town ended up working. And a bonded-cellular streaming rig that put live HD on any set from anywhere, which helped get South African productions moving again when the industry froze. We learned to run lean businesses with real systems underneath them.
Sc. 03 · The black box
The part nobody could see.
Here's the thing Rusty and I had in common. A freelancer runs bookings through an agent; an agency runs them through a back office. Both work, and both are a black box. You want to know if you're free next Tuesday, or who's on hold for a job, and the answer is always a phone call away. Rusty watched his coordinators burn whole afternoons chasing confirmations that lived in someone else's head. I built spreadsheet after spreadsheet trying to see my own working life.
So I built ShowCal for myself first — a personal agent to hold my calendar, my bookings, and my rates in one place I could finally see into.

The i/o is gone.
That became showcal.io: an operating system for crew. It was good. But it still required the i/o — you fed it, it showed you back. So we went back to the drawing board, waited for the technology to actually catch up, and rebuilt the whole thing from the ground up on infrastructure we'd battle-tested over five-plus years of real jobs, real crews, and real call times.
That's showcal.ai. The platform is live today. And the agent is back — but this time it's yours. We're building it to be always on: to answer with your availability the moment a job comes knocking while you're on set, so you don't lose the gig to a missed call; to plug into the tools you already use; and in time to take the back-office you dread off your plate. When both sides run on ShowCal, the endless back-and-forth just goes away.
All of it points at the one thing that got us into this: putting the right crew on the right jobs, and helping the work find you.
The i/o is gone. What's left is an agent.
