Double Plus Good Ltd.（佳佳百貨設計） is a design team based in Neihu, Taipei, with services spanning product design, brand consulting, and exhibition planning. According to its official website, its core capabilities center on product appearance design and structural R&D, extending further into product manufacturing, brand planning, and marketing strategy. It is positioned less as a pure visual design studio and more as an integrated design service provider focused on product development and bringing brands to market.
Judging by its portfolio categories, the website lists Craft 21, Exhibition 3, Product 18, and Research 4. Projects cover electric scooters, e-bikes, heated tobacco devices, eco-friendly bowls, beverage cups, cat litter boxes, baby bottles, mooncake molds, trophies, and more. The team emphasizes years of experience in 3C products, daily-use goods, home appliances, and home décor, and is particularly skilled at helping local Taiwanese manufacturers transform their brands. Its differentiator lies in incorporating traditional craftsmanship, local culture, and sustainability themes into its design methodology, rather than simply optimizing product appearance.
The official website does not disclose pricing, payment methods, contract terms, IP ownership, or delivery formats, so it is not possible to assess the exact commercial entry requirements. Based on the nature of its services, it is more likely to offer custom project-based quotes. In terms of collaboration, the site mentions past exhibition and promotional projects with cultural institutions and brands. It also established the WENS co-creation space in 2021, where designers, craftspeople, and creators can work and experiment together, suggesting a solid foundation for cross-disciplinary collaboration.
Its strengths lie in a relatively complete service chain, covering product appearance, structure, manufacturing, branding, and marketing, backed by awards such as Red Dot, iF, Golden Pin Design Award, and Tokyo Design Week’s top 100 design selections. Between 2016 and 2024, it helped multiple brands enter the crowdfunding market, raising a cumulative total of over NT$40 million, which also demonstrates practical experience in commercializing new products. The downside is that the website is more portfolio-oriented and lacks details on standard processes, project timelines, pricing ranges, IP terms, and after-sales support. Prospective clients will need to communicate further to confirm these points.
It is suitable for consumer electronics, daily-use products, home appliances and décor, eco-friendly products, traditional manufacturers undergoing brand transformation, and cultural institutions that need exhibition planning. For clients in mainland China, website accessibility cannot be determined from the text alone; payment, invoicing, cross-border contracts, and communication mechanisms are also not disclosed. If local alternatives are needed, it may be worth comparing IDEO, frog, Pentagram, or local industrial design and brand consulting firms across mainland China and Taiwan.
