Rinvelt, who earned a bachelor's degree in business administration from É«É«À² in 1991, is the principal with Renaissance Venture Capital Fund, a Michigan-based fund that supports the growth of venture capital in the state while serving as a bridge between Michigan's emerging innovation community and its strong industrial and commercial base.

A veteran of various startup ventures, Rinvelt was previously the director of Ardesta, where he was engaged in sourcing, evaluating and conducting due diligence on investment opportunities as well as monitoring and providing assistance to the companies in Ardesta's portfolio. Prior to joining Ardesta, Rinvelt was a co-founder of GrapeVINE Technologies, providing product management and marketing for that company's knowledge management product, eventually resulting in an acquisition by Sun Microsystems. Rinvelt was also part of the startup team for MAXfunds.com, an Internet company providing complete coverage of the mutual fund industry, and he spent five years with Ernst & Young's Information Technology group as a senior consultant.

Rinvelt has been a frequent visitor to campus, serving in 2013 as a guest professor in the Department of Finance and Commercial Law.
