Sander Nevejans is the CEO, Creative Director, and Lead Engineer at Seastex Ltd, holding degrees in electromechanical engineering and interior design. After 12 years working at his father's metal fabrication company, Sander shifted his focus to interior and product design. Over the next nine years, he worked for firms in the US, Japan, and the UK.

In June 2021, Sander founded Seastex, inspired by the potential of mussel beards, a by-product of the aquaculture industry. Following 2.5 years of R&D, Seastex successfully launched its MVP, the Acoustic Byssus Core (ABC) Tiles, at the 2023 London Design Festival. 

In 2024, Sander secured three grants to advance Seastex's innovative textile processing technology, enhance its MVP into a commercial product, and develop a new quality control method. With the opening of its pilot production facility in Glasgow in October 2024, Seastex has begun producing small batches of products weekly, with further exciting developments on the horizon.
