1. Kaushe: Social Commerce Meets the Group Buy
Kaushe—Japan's top-ranked group-buying app by annual sales—raised approximately 2.2 billion yen in a Series B round. Investors included Bonds Investment Group (lead), SIG Asia Investment (US Susquehanna International Group affiliate), Sumitomo Mitsui Marine Capital, Sony Innovation Fund, Mobile Internet Capital, Dentsu Ventures, and existing investors.
How it works: A Kaushe user finds a product they want to buy, then invites someone else to purchase the same item together. The group purchase typically unlocks a discount or benefit. It's a digital realization of social buying.
Why this model resonates: The behavior already exists in physical retail. At Costco Japan, you regularly see groups of people splitting bulk purchases—a pack of olive oil divided between two households, an oversized bag of chips shared among friends. Kaushe digitizes this pattern and makes it work for e-commerce.
The investors that participated—Sony Innovation Fund, Dentsu Ventures—suggest interest beyond pure financial returns. Sony and Dentsu both have strategic reasons to understand how social dynamics influence consumer purchases. Group-buy data reveals something that ordinary e-commerce data doesn't: who buys together with whom, and why.
2. Vattenfall's Wind Blade Skis: Upcycling the Hard Part
Swedish utility Vattenfall announced it would transform decommissioned wind turbine blades into skis and snowboards.
The recycling context: Approximately 90% of a wind turbine can be recycled through conventional material streams—steel, copper, electronics. The exception is the blades, which are made from composite fiber materials (fiberglass, carbon fiber, and resin) that are difficult to separate and process. Most blade disposal today involves shredding and landfilling.
Vattenfall's solution for the remaining 10%: convert the blade material into durable sporting goods. The structural properties that make turbine blades strong and lightweight—composite fiber construction—are also the properties that make good skis.
The model: This is upcycling at industrial scale. Rather than downcycling (shredding into low-value aggregate) or landfilling, Vattenfall is converting the material into a product with meaningful value.
What would make this better: Tracking recycling rates publicly—not just announcing the program, but reporting annually on what percentage of decommissioned blades go into skis, what percentage go to landfill, and what the trend is. Making recycling rates visible creates accountability and generates data that the industry can learn from. When companies make recycling rate data public and comparable, it creates a race to improve.
