Private-equity firm CoreCo has an investment thesis you’re not likely to read about in The Wall Street Journal. The $54 million fund spots high-growth businesses in Central America that operate with sustainable business practices.

  • Expanding financial services in India
  • Seeding early-stage social ventures in the U.S.
  • De-commoditizing commodities
