A founding story

A Cyber-shot in 2002, a market stall, an accidental prototype, and the long way back to the culling desk.

The long way back to the culling desk.

The oldest digital photographs in my archive are dated September 2002. The camera reported its model to the file as, simply, CYBERSHOT — one of those early flat Sonys that felt like the future and, for its time, produced beautiful images. I used to love photographing streams, flowers, nature — anything that would hold still long enough. I was fourteen. To fund the next camera I had my eye on, I sold greeting cards at the local market.

That next camera was a Sony F828 — the one with the odd twisting body and, for its day, a serious amount of capability. I got there eventually. I mostly remember pointing it up: long, patient exposures of the night sky, a fairly primitive kind of astrophotography, waiting to see what the sensor had caught that my eyes couldn't.

I didn't become a professional photographer. I became a software engineer. The two never quite stayed out of each other's way.

An accidental prototype

Years later I was living in Montreal — I'd met someone from there while travelling, and stayed, for her and for a city with more creative energy than I'd struck anywhere else. I was retraining as a web developer, and gave myself a first proper self-assignment: build something real, end to end. The app I chose to build was called Stockify. Its README describes it in one line: quickly tag and remove unwanted photos from a photo collection. Arrow keys to pick and reject. A grid to browse. Batch-remove the rejects.

My first act as a software developer was to build a culling app. It took me another decade to realise the dream.

Narrative

The hint got louder. I spent two years at Narrative, working on culling software used by professional photographers all over the world. I have a lot of respect for what that company did — James Broadbent, a wedding photographer who'd lived the problem himself, more or less created the AI-culling category with Narrative. Working there taught me how deep the problem runs for repeat-shoot photographers: culling isn't a niche annoyance. It's the tax on every wedding, every event, every session — thousands of frames sitting between the shoot and the art.

Full circle

A few years later, when it came time to work out what was next, I kept arriving at the same answer: I liked working on photography software too much to work on anything else. So I went back to the start — the kid with the Cyber-shot, the web developer with the arrow-key prototype — and set about building a culling tool I could only have dreamed of twenty years ago, with everything I'd learned in between. Once I started, I couldn't stop.

The standard

Cullibrate's promise is speed you can feel, and that sort of speed isn't a feature you add — it's a discipline you keep. Early on I spent two weeks running hundreds of experiments across thousands of images, measuring load times against what the hardware can theoretically do, and whittling at the gap. The first thing a friend said on trying it: "that loaded instantly." That's the golden stamp I was after.

That's the plan, stated plainly: take a career's worth of precision engineering and point it at photographic artistry — at the unglamorous, every-shoot work that sits between photographers and their best frames. The kid at the market stall would mostly want to know it loads fast. It does.
