Investment Thesis

Boom Capital invests early in founders building at the frontiers of science. The firm positions founders as "scientist-protagonists" and focuses on breakthrough innovations in frontier sectors including genomics, machine intelligence, aerospace, new chemistries, and adjacent deep science areas. Solo GP Celestine Schnugg specifically treats technical founders with scientific rigor as the protagonists of breakthrough ventures, seeking to back underrepresented leaders tackling non-obvious, ambitious scientific problems.

Founder Preferences and Investment Approach

Boom Capital prioritizes:

  • Highly technical, science-based founders with deep domain expertise
  • Teams tackling high technical and market risk problems
  • Underrepresented leaders in frontier science
  • Early-stage founders building durable science companies

Celestine Schnugg is known for being the first institutional investor in portfolio companies including Mammoth Biosciences, A-Alpha Bio, and Fauna Bio, demonstrating a pattern of early conviction in exceptional scientific teams.
