2 min read

Monolithic Power Systems, Inc. (MPS) (Nasdaq: MPWR), a leading company in high-performance power solutions, today announced the acquisition of Axign B.V., a Enschede-based fabless semiconductor startup that specializes in breakthrough analogue/mixed signal technology and IC’s for audio amplifier systems. The acquisition means that has sold its stake in Axign. The fund has been a shareholder of the Enschede company since 2021.

The chips from UT spinoff Axign distinguish themselves by combining superior audio quality with very low energy consumption, two important features for modern, portable audio systems. CEO of Axign, Paul Sandberg: “We have been able to grow Axign into a global player in the audio industry. MPS and Axign have been working strategically together for a long time because the products fit well together. With the increasing integration of components, the acquisition is a logical next step.” In addition, MPS's sales organization and reputation will help expand the customer base in the consumer and automotive industries, Sandberg expects: “This is an important strategic step for us in our further development towards market leadership.”

“When I listened to music from an Axign amplifier, I instantly recognized the excellent sound quality — the rich texture, wide dynamics, and clear spatial resolution,” said Michael Hsing, the founder and CEO of MPS. “I realized that combined with MPS’s technologies, we can bring that audiophile quality to the mass market. Axign’s passion for delivering best-in-class performance products matches our culture — the pursuit of excellence.” MPS will retain the Dutch team and the office in Enschede will become their 'Center of Excellence' for audio applications, leveraging Axign’s established local presence with universities. 

From small startup to global player

Axign was founded in 2014 and has supplied audio controller chips to leading brands such as Harman Kardon, JBL, Bluesound and Masimo. Initially, the company received backing primarily from business angels. As it progressed, notable investors such as Innovation Industries, KBC Focus Fund, Ten Cate Investeringsmaatschappij, Atlantic Bridge,, and Innovatiefonds Overijssel came on board, strengthening its financial support.

Arjan Gobel, partner at “We are excited about this acquisition as it will allow Axign's technology to be implemented on a global scale. MPS has the resources and expertise to bring Axign to the next level.”
