Moonlight
Moonlight is a San Francisco seed-stage startup founded in 2023 by Stanford MBA and former Activision product manager Siran Jiang. It began as Moonlight Focus, a science-backed productivity and biohacking app built around ultradian rhythms, live focus tracking and flow-state interventions, and has since evolved toward Moonlight AI - a personalized learning platform that turns any topic into gamified, AI-generated quests for children. Across both incarnations, the through-line is the same: use behavioral science and playful mechanics to help people direct their attention on purpose.

Kyron Learning
Kyron Learning is an AI education company building an interactive video platform that turns recorded lessons into two-way tutoring conversations.

Founded in 2022 by former Google Cloud AI VP Rajen Sheth and Qwiklabs founder Enis Konuk, the public benefit company raised a $14.6M Series A in December 2023 to open its platform to any learning provider.
