The London company turned a rejected bicycle-wheel ad into spinning LED displays used by Nike, Coca-Cola and the Sphere. Its real product is not a hologram so much as a carefully engineered interruption.
The London startup began by making famous faces speak new languages. Its real business arrived when ordinary employees asked for something less glamorous: a way to turn the next PowerPoint, policy update or training manual into video without booking a studio.

Captions began as a clever subtitle app. Now it cuts footage, fixes eye contact, dubs speech, builds AI presenters and even takes edit notes by text - useful power for people whose real job is not editing video.

Elai gives the dreary slide deck a presenter, a voice and a passport. For learning teams buried in updates and translations, that trade can be genuinely useful - as long as nobody mistakes an avatar for an actor.

Talking avatars draw the eye; the clever move is turning a dusty policy deck into editable, multilingual training without booking a camera, a presenter or half the calendar.

Creatify can turn a product link into a small army of ads, then help launch and judge them. The clever part is the workflow; the catch is that cheap abundance still needs an editor with taste.

A failed chat app, a rejected exit and a stubborn interest in how people express themselves led Akash Nigam to spend nearly a decade building digital characters. Now Genies is trying to give artificial intelligence a face, a wardrobe and somewhere to play.
The Los Angeles startup began with animated news, found money in celebrity cartoons, rode the NFT wave, and emerged with a more practical bet: persistent, game-ready AI characters. The lesson is not to predict the next platform perfectly - it is to keep the expensive technical core while replacing the story around it.
HeyGen wants to make the camera optional. Its digital twins, translation tools and video agents turn one human performance into a production system that can speak to almost anyone.
