Praktika.ai
Praktika.ai is an AI-powered language learning app that lets people practice speaking through conversations with personalized AI avatar tutors. Instead of the tap-and-match drills common to language apps, Praktika simulates the responsive, spoken back-and-forth of a private tutor - complete with realistic voices, accents and emotional inflection - at roughly $8 a month versus hundreds for a human tutor. Founded by the team behind AI service firm Cleverbots, the company reports over 30 million learners, 1.2 million monthly active users across 100 countries, and raised a $35.5M Series A led by Blossom Capital in May 2024.
Flow Club
Flow Club is a virtual coworking community that runs live, hosted focus sessions where people work side-by-side on video to get into flow and beat procrastination. Built around 'body doubling' - the idea that the quiet presence of others working keeps you on task - each 50-minute sprint opens with quick goal-setting, runs on focused silence with music, and closes with a recap. Founded in 2020 by Ricky Yean and David Tran, the Y Combinator (S21) startup has become a popular tool for remote, independent, and neurodivergent workers, often described by its founders as 'Peloton for coworking.'
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.
