What Musio does

AKA株式会社 (DBA: Musio) is a Tokyo-headquartered AI company, with US parent AKASTUDY LIMITED (California), that develops conversational AI products centered on its proprietary Muse AI engine. The core offering is the Musio AI social robot and a portfolio of consumer/enterprise applications — MuseSpeak (speaking assessment), MuseReplica (AI dubbing), Musio ESAT-J (English exam preparation), ReSmart (cognitive enhancement), Musio Edge/EOS (enterprise sales training), and Musio Academy (educational platform) — spanning NLP, computer vision, speech, and generative AI capabilities. The company serves English-language learners (particularly in Japan and Korea), K-12 and higher education institutions, enterprise sales teams, and the entertainment industry.

The business model combines hardware sales (Musio robot line — though new registrations closed in 2025 with after-sales service ending March 31, 2026), subscription services (Friend Plan, Musio English, Musio Academy), app-based monetization (ESAT-J, MuseSpeak premium tier), and enterprise B2B offerings (EOS sales training, MuseReplica dubbing). Distribution combines direct e-commerce, app stores (iOS/Android), retail partnerships (SoftBank C&S for Japan, Isetan Shinjuku), and direct B2B sales to educational institutions. The company has deployed its robots in approximately 250 educational institutions across Korea and Japan and reached 170,000 ESAT-J app downloads as of August 2025.

The company reports 8 employees in Japan and 30 globally (as of January 2023), with registered capital of 16.11 million yen. It is privately held, founder-controlled by CEO Raymond Jung, and has no disclosed institutional venture funding beyond a 2015 Indiegogo crowdfunding raise of $101,167. Recent strategic emphasis has shifted toward software/services (especially MuseReplica launch in March 2025 and Korean education expansion in 2024) while pulling back from consumer hardware.
