Bas Rieter at Dutch Founders Fund specializes in B2B marketplaces and recommerce in under-digitized industries like scrap metal and refurbished electronics, where he focuses on adding grading, inspection, and financial layers to legacy pen-and-paper markets. His background includes running his own venture and managing over €1M at ASIF Ventures while in his early 20s, giving him operator experience from both sides of the investment table that shapes his direct, no-bullshit approach to founder feedback and his emphasis on ultra-focused niche market entry strategies.
