ArtMaster, the Prague-based makers of the successful Artie piano learning app, have raised a $2.4M seed round. Joining past supporters such as Robert Kyncl (CEO, Warner Music Group) and Jaroslav Beck (founder of Beat Saber, acquired by Meta), new investors include Factorial Capital, Reflex Capital, Moises, Nir Zicherman (founder of Anchor, acquired by Spotify), Grant Davis (founder of Wand, acquired by Krea), and Eliska Vorel (Google/Deep Mind, PM at Gemini). ArtMaster will use this funding to continue to build and refine AI models that support independent development of creative skills, starting with musical performance.
“In my view, one of the highest and best uses of AI is to help people learn. AI models have expanded beyond language and can now listen to people play music and meet them at their skill level. This unlocks an entire category of how people can learn beyond ChatGPT.” notes Matt Hartman of Factorial Capital, who while at Betaworks was the first investor in Hugging Face, the popular hub for open-source AI developers.
Artie is ArtMaster’s first learning app. According to the company, it provides personalized learning paths and feedback on users’ instrumental playing. With personalized learning paths and responsive feedback to playing, the company says Artie reached more than 500,000 users and generated more than 100 million social views in its first year.
Since October 2025, paying subscribers and monthly recurring revenue have grown 38% and 39% month-over-month respectively. Once they download the app, many users stay engaged. Aspiring musicians in the top 10% of users clock sessions that run an average of 36 minutes.
This engagement comes as no surprise due to the society-wide interest in self-development and self-directed instruction. Bite-sized microlearning is now part of many people’s everyday lives, as the success of apps like Duolingo demonstrate. Learners increasingly expect highly personalized experiences with feedback that helps them improve and lessons that target what they need to master, the kind of experiences enabled by ArtMaster’s AI models.
Along with languages, learning musical skills is frequently cited as a personal aspiration by consumers. More than 700M people worldwide spend 65B hours learning music every year, and around 50B of those hours are solo practice without the guidance of a teacher. This time can feel frustrating and unproductive, leading players to seek ways to practice more intentionally. Artie and ArtMaster have cracked the code to provide this guidance.
ArtMaster was inspired by co-founder Radim Vysoky’s moment of frustration in music lessons: He wanted to dive in immediately and start playing, not drill endlessly. He wanted to play the music he loved, not the canonical classical repertoire. The experience urged him to rethink how music is taught and to break down learners into specific types.
The resulting approach became the basis for ArtMaster, a successful music school in Prague that Vysoky co-founded with Michal Novak. ArtMaster grew rapidly during lockdown as the school pivoted online and created successful video lessons. Yet something was missing: that personalized feedback a teacher gives a student. “Beginners are often making six mistakes at once. They need help prioritizing what to tackle first,” Vysoky reflects. “Even the best video can’t give you that. We decided we needed to create an app that would give real guidance, structure your practice, and help you meet your goals as a learner more quickly.”
“AI can personalize learning for any physical skill, and this is where we’re heading, building on what we’ve achieved for music,” muses Vysoky. “We’re just starting with music, and we plan to go way beyond it. Music demands you develop muscle memory, analytical ability, and emotional expression all at once, and these elements are transferable to other skills. We plan to apply our models to more instruments and then to more creative skills that enrich people’s lives.”
