Investment Approach

  • Profit driven. Our fund is private, for profit, and ROI driven.
  • Networked capital & deal sourcing. Every year, we raise capital from up to 99 alums ($50k – $500k per investor). We are introduced to deals by our investors and others in the MIT venture ecosystem.
  • Diverse and broad. We invest in 15-25 deals per year spanning a range of industries, stages, and geographies.
  • Connected co-investment. We primarily invest alongside top-tier venture investors. We do not lead deals, price rounds, or take Board seats. We aim to be valuable to the portfolio company and frictionless in the deal.

Our Style

  • Intentionally inclusive. We are an experienced, diverse community from different MIT departments and backgrounds, with different reasons for being involved.
  • Open. Our level of community involvement and transparency is unprecedented in the VC community.
  • High tech and high touch. We make intelligent use of technology, while also enjoying meet-ups and connecting.
  • Hard-nosed, soft-hearted. We are tough decision-makers and invest in only a small percentage of the deals we see. Yet we’ll hear anyone’s pitch and strive to be supportive and helpful.
  • Optimistic. We believe that we can help foster entrepreneurship and aim to add value for anyone in the Castor Ventures community.
