Why Clients Choose Us

Wall Street discipline, applied to the climate economy

Our founder, Gary LaDrido, built his career executing mandates at Morgan Stanley and across global capital markets. We bring that institutional rigor to a sector that demands both financial sophistication and genuine domain expertise.

  • Deep specialization in clean energy, infrastructure and sustainability — not generalist coverage.
  • Cross-border execution with sponsors, developers, corporates, governments and institutions.
  • Access to a global base of pensions, endowments, foundations, sovereign wealth funds, insurers and family offices.
  • Senior-led engagements with bespoke structuring on every transaction.
Built for the energy transition and the next economy
