Classroom engagement tools built for chemistry students

We’re changing the way college students learn STEM

The tools that college students use to learn math and science haven’t fundamentally changed in 100 years. Today, students have a myriad of textbooks, online homework, and response clickers, which mostly rely on static content and generic multiple choice or fill-in-the-blank problems. Instead, we are delivering uniquely tailored, touch-based tools that create new ways for students to visualize and experience abstract math and science topics.

Our first app, Chem101, replaces the clicker and provides tools for chemistry professors to engage their students in the classroom. Chem101 features a module that allows students to intuitively draw and visualize Lewis structures on their mobile devices. Rather than multiple choice questions, students draw and submit molecular structures in assignments that professors create inside the app. When students submit structures, professors see what their students are drawing in real time and Chem101 automatically pulls out the most common mistakes. Chem101 was piloted during the Fall 2016 semester at 10 U.S. colleges/universities including Carnegie Mellon University, Columbia University, and the University of Cincinnati.

We are growing a team of visionary scientists and engineers to expand our approach into a broad range of math and science topics that cause pain to many of the 4.5M U.S. college students who take STEM courses every year. With more engaged students, we aim to reduce the college STEM major dropout rate, fill the workforce gap, and help create the next generation of scientists, engineers, and technologists.

Meet the team defining the future of educational software

Justin Weinberg


Justin is the visionary behind 101 and has been teaching forms of math and science for nearly a decade as a tutor and a university TA. Prior to 101, he created Chem Pro, a mobile app with over 500K downloads that is designed to help students learn how to solve chemistry problems with video lessons. Now, Justin is leading 101 to bring its interactive tools to college STEM courses across the country. Justin is a PhD candidate in chemical engineering at Carnegie Mellon University and is a recipient of the prestigious National Science Foundation (NSF) Graduate Research Fellowship.

Igor Belyayev


Igor leads technical development at 101, responsible for bringing our novel interactive experiences to reality on iOS and Android. He's worked as a mobile developer at startups like and Hackerati, as well as media companies like The Huffington Post and Viacom. Igor holds a bachelor's degree in mechanical engineering from The Cooper Union. Igor and Justin have been working together since 2011 when they originally teamed up to develop the first Android version of Chem Pro.

Bharani Rajakumar


Bharani is the co-founder and CEO of LearnBop, which develops an interactive learning system for K-12 math students. At an early age, Bharani recognized the inequities in education and created LearnBop to make high quality educational support available to every student everywhere. After five years of hard work, his vision has become a reality, and students are seeing real gains as a result of the data-driven, step-by-step approach he helped develop.

Harris Goodman


Harris is currently the Vice President of Business Development at Achieve3000 where he helps build strategic partnerships with the edtech community and drives revenue growth. Prior to Achieve3000, he co-founded Late Nite Labs, which focused on developing highly immersive digital labs for college science students. At Late Nite Labs, Harris spearheaded and secured a Series A investment, helped build out the organization, and managed the sale to Macmillan New Ventures all while helping the company grow 200% in under two years.
