Sourcebook is a networking service for the fashion industry connecting local textile producers, service providers and manufacturers directly to established and emerging creatives in the design sector.

We bring together a trusted network of industry experts with a fast growing community of makers and designers in order to initiate, implement and share new business concepts.

But we're not only active in the digital realm. Our offline activities include expert consultations – guiding you from concept stage to seasonal production – exclusive networking events, match-making trips abroad, cutting-edge seminars and professional tutorials, among other things such as material sourcing, serial production, logistics and distribution.

With a strong presence at progressive trade fairs and access to visionaries in the field of fashion, Sourcebook offers a platform promoting professionalism in the textile industry.

Founded in 2013, Sourcebook grew out of the EU-funded NEMONA project commissioned by the urban and regional development firm Inpolis. Since March 2015 Sourcebook operates as an independent limited company out of Kreuzberg, Berlin.
