Consulting · Bespoke AI · Team training

We don't sell AI off the shelf.
We study your business first.

Every company is different, so every system we build is different. We look at the real problems in front of you, design AI around them — and make sure your team actually knows how to use it.

AI consulting

We sit with you, map how your business actually runs, and find where AI saves real hours or real money — and, just as honestly, where it doesn't. You leave with a clear, prioritised roadmap, not a sales pitch.

Bespoke AI systems

Then we build it — designed around your specific problems, your tools and your data. Not a generic product with your logo dropped on top. A system that fits the way your company works, and grows with it.

Training for your team

Hands-on courses and workshops that take your people from AI-curious to AI-confident — tailored to their roles and the exact tools they use every day. Because the best system is worthless if your team doesn't know how to use it.

Made by 21:7 · From a single image to a finished film

Built from zero.

Two recent originals. One brand already existed — we built the film. One brand didn't exist at all — we built everything.

Brand exists · We built the film

Aqua Coco — from one photo to a Coca-Cola-style ad.

Aqua Coco is a real Brazilian coconut-water brand. The product exists; the film didn't. We took a single reference photo of the bottle and produced a hypermotion commercial — condensation, label snap-zoom, splash physics, pour cinematics — plus a creator-style UGC clip with a photoreal AI character. No on-set crew, no studio.

Aqua Coco — original product reference photo we started with

02Output · Built by 21:7

Same product · Different cut · Creator-style UGC

The same bottle reference, now in an authentic iPhone-candid vertical clip with a photoreal AI character on a Brazilian beach. Shown at its native 9:16 — the format it was built for.

VECTOR — a drone brand we invented from zero.

VECTOR doesn't exist. We invented the name, designed the V mark, produced three hero variants (white, red, raw), built the product visualisation, and shot a Tesla-style teaser film in a fictional Manhattan skyline. End-to-end brand creation — identity → product → film.
