CdeCiencia

CdeCiencia's real name is Martí, which he shares openly in his YouTube channel description. The channel name itself is a play on Spanish — "C de Ciencia" means "C for Science" — giving the brand both a personal and educational identity.

Yes. CdeCiencia created CosmoClass, an educational app he promotes under the handle @cosmoclass_app. He describes it as free in his Instagram bio, which fits his broader mission of making science and the universe accessible to Spanish-speaking audiences worldwide.

Both. Martí explicitly states in his YouTube bio that CdeCiencia explores the most fascinating topics of the universe and existence from a scientific but also philosophical perspective. That dual angle is a defining feature of the channel and sets it apart from more narrowly technical science accounts.

Yes. CdeCiencia published a video on Asteroid Apophis after NASA confirmed the key date tied to the asteroid's close approach. Space science is one of his core topics, and videos like this consistently drive strong engagement well above the category average.

CdeCiencia dedicated a video to an aircraft capable of circumnavigating the globe in roughly three hours, breaking down the aerospace engineering and physics that would make such extreme speed possible. It is a strong example of how he takes high-concept science topics and makes them compelling for a general Spanish-speaking audience.

Sezar Blue is a Spanish science communicator who collaborated with Martí on a video explaining why making aioli (allioli) is nearly impossible to do without error, applying real food science to a classic Mediterranean recipe. The crossover is typical of CdeCiencia's style of grounding scientific thinking in everyday experience.

CdeCiencia has partnered with PLAUD.AI, Trade Republic, MyHeritage, Brilliant, and Surfshark, all through sponsored YouTube integrations. The mix of AI productivity tools, personal finance, genealogy, and online learning reflects a sponsor profile well matched to his adult, intellectually curious audience.

The PLAUD Note Pin is an AI-powered recording device by PLAUD.AI that clips onto a phone and automatically transcribes conversations and meetings. CdeCiencia featured it as a sponsor in a YouTube video, pairing naturally with the productivity angle he occasionally explores alongside his core science content.

CdeCiencia has over 5 million subscribers on YouTube, placing him in the Mega creator tier for Spanish-language science content. His engagement rate runs far above the typical benchmark for science channels, which points to an unusually loyal and active community.

Spain is CdeCiencia's largest audience, followed by strong viewership from Mexico, Argentina, and Colombia, with a smaller share from Spanish-speaking communities in the United States. That reach across multiple continents makes him one of the most widely watched science voices in the Spanish-speaking world.
