Feedback:
“Anastasia, through Substanz, has become a key figure in the world of bio-based materials. Her knowledge of bio-based materials goes far beyond sourcing, she understands their real potential, their limits, and how they behave in actual production contexts. She helped us navigate a complex and fast-moving landscape, bringing both clarity and precision at key moments of our project. But more than that, she showed a rare level of commitment, staying involved, curious and generous, even beyond the scope of our collaboration. Substanz plays a crucial role in structuring this emerging field. It’s a rare and one of the only valuable bridge between emerging materials and real-world applications.”
