What's the story behind your product?

Cocoloops's answer

Cocoloops started from a simple problem: families living between languages struggle to find good children’s stories in their home language, and many kids’ audio apps are ad-heavy or English-only. Our team of audio producers, writers and engineers set out to build a safe, ad-free place where kids can hear well-narrated stories in the languages their families speak. It was the very problem the I as a founder faced, I am from India currently living in Switzerland and i find it very difficult to find stories for my children in Hindi language so that they understand and learn our culture and language, I tried recording my own Audios for stories as i could not also give much time making them learn and my children's were loosing my own language, so i decided to make cocoloops to help narrate stories in native languages to keep our heritage, language and culture alive.

Calcumber's answer:

When starting for a Master of Advances Study in Energy Systems, I was looking for a suitable state-of-the-art calculator. Then I built my own Calculator Calcumber and now the Eastern Switzerland University of Applied Sciences is using Calcumber for teaching students in thermodynamics.
