Antimatter Systems

Antimatter Systems is an education technology company building a peer-to-peer learning network where students demonstrate mastery by making memes, puzzles, and games rather than by writing essays or sitting tests. Founded by Jonathan Libov, the company raised a $2M seed round led by Version One Ventures in 2023, joined by Spacecadet, Ordinary Holdings, Haystack and Compound. Its classroom product lets teachers create meme-based activities with deadlines and instructions, invite students by shareable link, moderate submissions, restrict learners to view-only, work from a library of pre-approved templates, catch unedited-image uploads with plagiarism detection, and grade every submission in one place; the company states it should be free for schools. Antimatter also ships a Sorcerer AI instructional coach plus the consumer Antimatter: Creator and Antimatter: Universe iOS apps. The platform runs on the web at playantimatter.com. As of July 2026 the company publishes no public API, developer portal, SDKs, or machine-readable API specifications.

Antimatter Systems is profiled on the APIs.io network. Tagged areas include Company, Education, EdTech, Learning, and Classroom.

Antimatter Systems’ developer surface includes signup flow, support, YouTube channel, and 10 more developer resources.
