    Why Vinci & BMW Are Betting on 3D Wood Composites to Replace Steel

    Andres Mitnik is the CEO and founder of Strong by Form, a deeptech startup revolutionizing sustainable construction materials. With a background in civil engineering and advanced degrees from Harvard and NYU, Andres is tackling industrial decarbonization—responsible for 30% of global carbon emissions. Strong by Form has developed Wood Flow, a next-generation timber composite that replaces steel, concrete, and aluminum at a fraction of the weight and, critically, at a price point competitive with traditional materials. After seven years of development and over €5 million raised, the company has secured partnerships with industry giants including BMW, Deutsche Bahn, and Vinci. Now preparing for their Series A, Strong by Form is proving that climate tech can compete on both performance and cost in the $16 trillion construction industry. In this conversation, Andres shares the journey from prototype to commercialization, the challenges of deep tech fundraising, lessons from product-market fit research, and why he measures success not by exits, but by impact.
