 I'm Shaya and this is Sergei. We're from PolyUp. We just had a talk at the AI for Good Conference. We were talking about how to incorporate AI and artificial intelligence into making education better. So at PolyUp we're an education startup trying to empower a global community of problem solvers. So we have a digital math playground that makes math really exciting and experimental. Students can play around with all the elements of math and it's a ton of fun. I joined PolyUp about two years ago. I love the story. I love the people and I love the mission statement. So I've been managing the international relations ever since and in the last four months with something we called PolyChallenge. We got into 30 countries, more than 100,000 students and we solved more than 20 million problems. So these are our great numbers and we wanted to explain how can AI get advantage of all the data we got from all these problem solvers. And also we wanted to broader our community in a place where the UN is such a big thing.
