  "account": "Deeptech startup Strong by Form has secured €5.8 million in Series A funding to challenge concrete and steel in the construction industry. Founded in Chile, the company operates from Madrid, Santiago, and Stuttgart. Traditional concrete and steel construction are major sources of embodied carbon, limiting construction productivity. Mass timber solutions have faced challenges in achieving the same strength, span, and economics as concrete and steel. Strong by Form's answer is Woodflow-core, a structural slab designed to compete on strength and price, not sustainability. The market for concrete slabs is around $120 billion, while Cross-Laminated Timber accounts for less than $1.5 billion. Rather than competing with mass-timber producers, Strong by Form partners with them, offering a path into a market up to 80 times larger while improving margins by up to 50%. CEO Andrés Mitnik, an engineer by training, developed the idea after collaborating with architects interested in sustainability and efficient construction. The technology is inspired by the way trees grow, using computational design to place structural fibers only where needed, mimicking natural growth patterns. This results in a lighter product that requires up to 75% fewer trees than comparable mass-timber products. Strong by Form produces two products: Woodflow-core, used in high-rise and industrial buildings, and Woodflow-skin, an ultra-thin and strong architectural cladding already used in trains and interiors. The company's technology can utilize various wood species, aiming to use locally sourced wood to reduce transport emissions and minimize waste.",
