Quizizz
Quizizz is now Wayground. Trusted by educators in 90% of U.S. schools, Wayground is a supplemental curriculum platform that bridges the gap between district priorities and classroom realities and helps students hit grade-level standards faster. With AI support, teachers can personalize any resource once and automatically adapt it for each student's unique needs. From interactive assessments to differentiated assignments, we help educators spend time teaching students, not hunting for resources. Founded in 2015 as Quizizz and evolved into Wayground in 2025, we believe every student deserves access to grade-level resources in ways that work for their unique needs, and every teacher deserves standards-aligned resources their students love using. Let's find a way—together.

ClassDojo
ClassDojo's mission is to give every child on Earth an education they love. We started by building a network that connects teachers, children, and families. ClassDojo’s flagship app is the #1 communication app connecting K-8 teachers, children, and families, globally. They use it to share what’s happening throughout the day through photos, videos, messages, and activities. It is actively used at an unprecedented scale: in over 95% of US schools, reaching ~51 million children in ~180 countries, all built by a team of 65 people [1]). We are now beginning to use this network to give kids the best learning experiences in the world, far beyond those a standard school can provide. We hire for talent density. Our team comprises the most talented, entrepreneurial, and innovative teammates from around the world, with deep backgrounds in education and large scale consumer internet, including Instagram, Netflix, Dropbox, Uber, Y Combinator, and more. We’re building a company where the most talented people want to work. We believe you’ll do the best work of your life here—and you’ll pioneer the future of education, too.
