*Inc. Founder Friendly Investors  – Awarded by Inc. Magazine in October each year. This determination is made following application from private equity / venture capital firms that have exited U.S.-based, founder-led, private portfolio companies.

Founders fill out a questionnaire about their experiences partnering with private equity and venture capital firms and shared share data on how their portfolio companies have grown during these partnerships.
