Managed by Mundi Ventures, the textile fund is said to align with Inditex's broader strategy of supporting start-ups focused on developing new materials and technologies that minimise environmental impact.
According to Spanish publication El Confidencial and Reuters the move underscores Inditex's commitment to sustainability and its aim to decarbonise its business by 2040.
Inditex also plans to make 100% of its raw materials and fibres more sustainable by 2030.
By the end of 2023, more than 50% of the raw materials it incorporated into its collections had come from recycling or organic or regenerative cultivation.
In July Inditex acquired a stake in Galy, a start-up founded in 2019 in the US, which is developing an innovative process for growing cotton in a laboratory from cotton stem cells to produce sustainable material.
Inditex has previously invested in US companies such as Circ, known for its textile-to-textile recycling efforts and Inditex's flagship brand Zara launched a clothing collection with Circ that was made from recycled polycotton blended textiles.
