Turning math into something fun and engaging for kids is a big win 🎉🧠. Kukumber feels like the kind of AI tool that builds confidence and curiosity from an early age.

As a new dad, I keep an eye on all innovations in digital products for kids. I haven’t yet built a strong view on that, but getting them to use tech for studies seems something unavoidable.

Love the idea and the first version of the app is fantastic. In fact it’s so good, I ended up playing with it for 2 hours…and I hate math))) Elena, Ivan, well done as always, I’m rooting for you!
