ProtoBag Studio supports emerging bag brands with custom bag development review, paid sampling coordination, OEM production follow-up, shipping, logistics, and reorder support. We work with independent designers, indie founders, and growing brands across European design hubs (Berlin, Amsterdam, Copenhagen, Stockholm, London, Paris, Milan, Munich) and beyond.
Independent designers and indie founders often need one production-side workflow rather than a loose list of factory contacts. ProtoBag Studio helps coordinate the path from project review to paid sampling, factory communication, production follow-up, shipment preparation, logistics, and future reorders.
The company is led by Hao-Wei Su, who bridges client communication and production-side coordination in English, German, and Chinese. The goal is to keep the client-facing work clear while the production-side follow-up is handled in one organized workflow.
Our production facility carries over twenty years of bag-making heritage, with 120 highly skilled workers and 330+ machines on the production floor. Equipment and quality control are kept on the same site, which is why sampling and production stay consistent from prototype to batch. The facility works across backpacks, totes, duffels, slings, technical bags, travel pouches, and modular carry tools, in nylon, polyester, canvas, PU, vegan textiles, and recycled materials.
Recent client outcomes include 15M+ units shipped for one North American partner and $12M in revenue generated for one partner in 2025, with 10+ international brands currently in active development. The company works best with independent designers, indie founders, growing brands, and niche product teams across European design hubs — Berlin, Amsterdam, Copenhagen, Stockholm, London, Paris, Milan, Munich — and beyond.
Four things define the support model: clear communication in English, German, and Chinese; paid sampling coordination; production follow-up; and strict confidentiality, with NDA arrangements available before sensitive design files are shared. Selected facility certifications such as Higg and SMETA are available on request where relevant to the production arrangement.
