We provide Entrepreneurial Stage Capital to SaaS companies in B2B markets. Dedicated to industries being transformed by IT, Tamarind Hill concentrates specifically on investments within the healthcare and logistics verticals. With offices in Ann Arbor and Columbus, we focus on opportunities throughout the Midwest.

We invest in very early- through growth- stage companies that need $50,000 to $5,000,000 in new capital, and which possess key attributes that lead to sustained, predictable growth.

We have direct experience with entrepreneurial growth-stage companies and know where we can add value and when we should get out of the way.
