Mobile-first teaching and assessment tools built specifically for college STEM courses

Our mission

101 builds mobile-first teaching and assessment tools specifically for college STEM courses. Current STEM course tools such as online homework and response clickers poorly utilize technology to engage students in learning by wrapping generic question types (multiple choice, fill-in-the-blank, etc) around static textbook content. Instead, we deliver uniquely tailored, touch-based interfaces that create new ways for students to visualize abstract math and science topics during critical problem solving sessions.

Our first app, Chem101, provides tools for chemistry instructors to create engaging in-class and homework assignments around these modules and receive intelligent, real-time feedback on student performance. The first module of Chem101 will be piloted during Fall 2016 in over 30 U.S. colleges/universities including MIT, Carnegie Mellon University, and Columbia University.

We are growing a team of visionary scientists and engineers to expand this 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 towards filling the workforce gap and to 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 math and science for nearly a decade as a tutor and a university TA. He created the mobile app, Chem Pro, based on his experience teaching chemistry and that has recently crossed over 500K downloads organically. Now, Justin is leading 101 to bring its new interactive platform to college courses around the world. 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 Learnosity, where he helps build strategic partnerships with the ed tech community and drives revenue growth. Prior to Learnosity, 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.
