Lirvana Labs is an early-stage, VC-backed ed-tech startup turning the dream of truly personalized learning into everyday reality. Backed by Kapor Capital and other mission-aligned investors, with design and development partners such as Sesame Workshop, TNTP, Educators Rising, Stanford University’s Deliberative Democracy Lab, MIT Solve and MIT Raise, we are racing toward our next horizon of impact and ground-breaking use of AI to push the envelope in learning, teaching and coaching.
Our flagship suite combines Yeti Confetti Kids—a playful AI tutor that adapts on the fly—with a Teacher Co-Pilot Portal that delivers real-time insights and one-click actions for educators. Under the hood, we’re pushing LLMs to the edge of what’s possible in recommendation, session planning, and formative feedback, ensuring each student gets just-right challenges while teachers stay firmly in the loop.
We’re gearing up to expand our elementary literacy, math and SEL programming success beyond K12, with new and existing market expansion across APAC, the Middle East, and the U.S. Join us if you’d rather build the future of education than wait for it.
