About Us

KB Partners, LLC is a suburban Chicago based investment firm established in 1996 to make investments in a variety of angel funded and venture capital opportunities. KB's objective is to build dominant new enterprises by working in partnership with talented entrepreneurs and experienced managers.

To be successful at building lasting companies, we feel it is critical to develop strong relationships with the entrepreneurs, investors, and other venture capital firms with which we work. Disagreements and difficult situations will always arise, but a foundation of mutual respect and cooperation helps to ensure long term success.

Our pledge to you:


  • We will always conduct our business in good faith, with honesty and integrity.
  • We will exhibit professionalism in all of our endeavors and conduct ourselves with the highest ethical and moral standard.
  • We will strive to create a win/win situation for all participants with whom we become involved.

Ultimately, we are a service organization dedicated to providing significant value to both the entrepreneurs we finance and to our investors. We are committed to creating an environment which allows entrepreneurs to feel confident that we will provide strong support in both prosperous and difficult times, and we will work constantly to foster a productive, enjoyable, and long-term relationship.


At our core, we are entrepreneurs with a passion for building great companies. We've been in the operating trenches before and recognize that building and growing early stage companies is as much art as science. No business plan or financial forecast can prepare an entrepreneur for the myriad of situations that will be faced when starting and building a company. However, experience can be the difference between exponential growth and severe growing pains.

The principal of KB Partners has a proven track record of helping young companies transform themselves into market leaders. We have faced many of the issues confronted regularly by the entrepreneurs that we back. Accordingly, our ability to apply our own operating experiences to these challenges enables us to provide hands-on assistance with all aspects of an organization.
