Felix Plapperer built BOOOM around his work with sennder's cofounders, pairing founders with 12–18 month one-on-one mentoring from David Nothacker, Julius Köhler, or Nicolaus Schefenacker, and drawing on his own experience helping scale sennder to over 1,000 employees and more than €400 million raised. As a solo GP, he's brought together backing from unicorn founders and partners at firms like Accel, Index Ventures, and Creandum, while his focus on supply chain and procurement technology carries over from his earlier work at Paua Ventures and SquareOne.
