Founder, GPT-Video
Alessio builds GPT-Video, an AI video editor that turns long recordings into short vertical clips. He works on the clip-scoring and captioning pipeline day to day, and publishes short-form video with the tool while building it: the workflows in these posts are the ones he runs. Before GPT-Video he built Quantly, a multi-agent AI platform for retail trading. He works between Milan, New York and Hong Kong.
