What Solfeg.io does

Solfeg.io, operating as SIA Solfegio, is a Riga, Latvia-headquartered EdTech company founded in 2017 that builds a music education platform combining a proprietary Easy Notation™ method with a curated library of simplified popular songs. The platform is delivered via two primary products: a web-based Online Platform for Schools designed for classroom projector-led teaching, quiz assignment, and student progress tracking, and a mobile app (iOS, Android) plus Chrome desktop PWA for self-directed learning of guitar, piano, ukulele, and singing. Underlying technology includes real-time audio processing for backing track isolation, pitch shifting, tempo control, live performance feedback, and an AI Help Assistant that provides personalized guidance for music-related questions. The company also produces lesson plans, theory quizzes, and instrument classes aligned with K-12 curriculum standards.

Solfeg.io serves two primary customer segments: K-12 schools and school districts (its core enterprise vertical) and individual self-learners (B2C via app stores). The go-to-market is dual-track — freemium with self-serve app store subscriptions for consumers, and a sales-assisted enterprise motion for schools with free 2-week trials, quote-based pricing, purchase order support, and annual invoicing (no automatic renewals). School pricing tiers include Free, Solo (free via referrals), Maestro (mid-tier, curated library), Virtuoso (full 200+ song library), and Divo ($1,499/year premium tier with priority support); district-level multi-school subscriptions offer centralized billing. The company integrates with Google Classroom for assignment syncing, uses Stripe for web payments, and Apple/Google for in-app billing. Distribution is global, with operational offices in Riga, Malmö (Sweden), and Claymont, Delaware (USA).

Solfeg.io has achieved meaningful scale with 25,000+ schools using the platform, a 4.6-star App Store rating, and cumulative venture funding of approximately $1.02 million (largest disclosed round: $1,018,556 led by Iron Wolf Capital in September 2021). The company holds COPPA compliance certification, enabling safe use by US students under 13. Co-founders Tom Gale (CEO) and Lauma Kazaka (COO) lead the company, which operates with 11–50 employees and has received industry recognition from GES Awards, MIDEM, SXSW, QS, Forbes, and Capterra.

Emerging players

• Flat: Flat is a music notation platform with collaborative editing and classroom tools. Comparable to Solfeg.io on the notation and classroom-collaboration layer, though its primary focus is composition/notation rather than instrument instruction with pop songs.

• Noteflight: Noteflight is a web-based music notation and learning platform used in schools for composition and theory lessons. Comparable to Solfeg.io on the music-theory and web-classroom angle, though weaker on consumer instrument instruction.
