Fashion for Good

Amsterdam, Netherlands · Accelerator

Fashion for Good is an Amsterdam-based innovation platform and accelerator dedicated to making the fashion industry more sustainable and circular. Launched in 2017 with backing from founding partner Laudes Foundation (formerly C&A Foundation), Fashion for Good runs a 9-month accelerator program for startups developing technologies or business models that improve fashion’s environmental or social impact. Focus areas include innovative materials (e.g. bio-based fibers, textile recycling), new dyeing and finishing processes, circular business models (rental, resale), and supply chain traceability solutions. Each batch (around 10 companies) receives coaching, pilot opportunities, and a small grant; uniquely, the program is venture client-oriented: Fashion for Good’s corporate partners – which include Adidas, Kering, PVH, Stella McCartney, C&A and other major brands – collaborate with the startups to test and implement their innovations. For example, early cohort member Ambercycle (USA) has partnered with Adidas on textile recycling pilots, and Pili Bio (France) worked with brands on microbial dyes. In addition to the accelerator, Fashion for Good runs Scaling Programs for more mature innovators to facilitate larger deals (often joint ventures or first-of-a-kind factory deployments). It also operates a public Experience Museum in Amsterdam showcasing sustainable fashion and educating consumers. By 2022, Fashion for Good had accelerated over 125 startups, helping many secure follow-on funding – alumni have collectively raised hundreds of millions. Notable graduates include Renewcell (Sweden, textile recycling, IPO’d), Natural Fiber Welding (US, plant-based leather, now partnering with Ralph Lauren) and Circular.Fashion (Germany, circular design SaaS acquired by Zalando). Fashion for Good’s success lies in its consortium approach: besides brands, it engages manufacturers and investors (like AccelR8, a fashion-focused VC) to ensure innovations can actually be adopted at scale. Its impact is tangible – alumni like Orange Fiber (Italy, citrus-based silk) have seen their materials used in collections by H&M and Ferragamo. As the fashion industry faces pressure to reduce waste and emissions, Fashion for Good has positioned Amsterdam as a key nexus of fashion tech and sustainability, proving that collaboration across the value chain can accelerate the transition to a Good Fashion future.

Sting (Stockholm Innovation & Growth) is Sweden’s leading startup accelerator and incubator, founded in 2002 and based in Stockholm.

Each year, ~25 startups participate in Sting’s programs, which are tailored to ICT, sustainability, and deep tech ventures. Sting offers two main tracks: the Accelerate program (a shorter, intensive accelerator with investment) and the Incubate program (a longer incubation with office space and coaching). Startups benefit from SEK 400,000 (≈€35,000) in pre-seed investment via Sting’s Propel Capital angel fund, as well as hands-on mentorship from experienced entrepreneurs. Sting is notable for its extensive network in the Nordics – participants get access to 80+ industry mentors and introductions to a broad investor pool in Sweden and internationally. The results speak volumes: Sting has supported 270+ startups since inception, with a survival rate over 70% and multiple high-profile alumni. Success stories include Yubico (security keys unicorn), Sellpy (fashion recommerce, acquired by H&M), and ClimateView (climate planning SaaS). In addition to funding and coaching, Sting offers free office space at A House in Stockholm, product development labs, and perks from partners. The program emphasizes key performance indicators (KPIs) and growth milestones – Sting aims to help companies reach first customers, significant revenues, or Series A readiness within 6–18 months. Beyond individual companies, Sting has played a crucial role in Stockholm’s ecosystem: it co-founded SUP46 (Start-Up People of Sweden) co-working space and hosts Sweden’s annual Startup Demo Day. Sting alumni have collectively raised over €600 million. With the Swedish ecosystem maturing, Sting remains a cornerstone – providing new founders with structured support, an entrepreneurial community, and that all-important first investment to turbocharge their growth.
