Tideline was founded in 2014 as a Certified Women-Owned Business by Christina Leijonhufvud, Ben Thornley, and Kim Wright-Violich, who together brought over three decades of impact investing experience to the firm and a vision to build a specialized consultant for the impact investing market. True to this vision, Tideline has played an important role in the growth and maturation of the impact investing industry with a long history of pioneering many of the concepts and practices that have evolved into today’s industry standards. From the introduction of “impact classes” to the development of a methodology for “impact verification,” Tideline has continuously helped raise the bar for impact investing with 145 projects completed to date and influencing clients which advise and manage $13.5 trillion.

Consistent with Tideline’s mission of “enabling investors to integrate and deliver impact with confidence,” our approach to impact investing consulting has always emphasized excellence, commitment, and openness. These values guide not only every client interaction and assignment but also how we grow the firm and empower our team. This ensures that our work is genuine and contributes to scaling the impact investing industry with integrity.
