What Thomastik-Infeld does

Thomastik-Infeld is a Vienna-headquartered manufacturer of premium musical instrument strings, founded in 1919 and operating today with approximately 206 employees. The company develops and produces high-performance orchestral strings (violin, viola, cello, double bass), guitar strings (acoustic, electric, jazz, and bass guitar), folk and world music strings (mandolin, mandola, oud, pipa, erhu, banjo, cavaquinho, Schrammel guitar), and rosin accessories. Its technology base rests on proprietary synthetic core formulations (the Dominant line, launched 1970 and claimed as the world's most widely played synthetic-core string), spiral rope core designs (Spirocore, since 1960), and an in-house extreme-precision rolling mill with 0.5µm accuracy, supported by a portfolio of more than 80 patents and registered utility models (28 of them granted under the current CEO).

Revenue is generated via hardware sales of replaceable string sets distributed through 593 authorized dealers across 60+ countries, a direct e-commerce storefront (shop.thomastik-infeld.com), a US distributor (Connolly Music Company), and a protected dealer portal. Sub-brands include DYNAMO/DYNAMO SOLO, RONDO/RONDO GOLD, DOMINANT PRO, Peter Infeld, Alphayue, EVERTONE, Infeld Red/Blue, Belcanto, and the recently acquired Jargar Strings brand (Danish, founded 1956, integrated in January 2026). The Infeld family retains ownership, with Zdenka Infeld serving as CEO since 2009.

The go-to-market model is product-led and centered on tone-color breadth, reliability, and artist endorsement (including Ray Chen, George Benson, Timothy Ridout, Santiago Cañón-Valencia, and Sergei Dogadin). Supporting marketing channels include the Stringtelligence educational platform (over 20,000 words, 90+ chapters, 19 video tutorials), the Stringfinder recommendation tool, trade show presence at NAMM (Anaheim), akustika (Nuremberg), and Music China (Shanghai), an extensive YouTube video library, social media including RedNote/Xiaohongshu for Asian markets, and a press area. Customer segments span orchestra players, soloists, chamber musicians, luthiers, guitarists across jazz/acoustic/electric genres, jazz bassists, world-music instrumentalists, and serious amateurs globally.
