ABOUT STEFFEN WALTER
My passion is to enable organizations to execute at the highest level, avoiding costly mistakes when turning great ideas into operational reality. My career has brought me from bench science to general business, spanning two continents. As a COO and former CSO/CTO with 25 years of immuno-oncology experience across R&D, CMC, quality, and commercial-scale manufacturing, I have a proven track record building and scaling transatlantic organizations from inception to public company, including oversight of INDs, GMP platforms, and supporting >$900m in financing. I’m currently overseeing the preparation of the CMC package for a CGT BLA submission. As such, I have been a trusted partner to boards and executive teams in high-growth, high-regulation environments. I emphasize pairing strong technology with strong teams operating with integrity. My working style is highly collaborative and highly structured, emphasizing efficiency. I’m a US/German dual citizen.Increasingly, I am also interested in contributing these insights at the board level, providing strategic guidance and operational discipline to high-growth companies.
