Track Record

Founded in 1996, JK&B has built a track record of generating exceptional returns for investors by identifying and investing in companies with technologies which have been critical to the growth of the world’s information economy.

A key to JK&B’s success has been its ability to leverage its substantial technology domain expertise to identify, analyze and access the most promising emerging technologies and the companies behind them. JK&B then provide these companies with financial support, strategic guidance and most importantly technical guidance to help them grow and prosper.

JK&B has distinguished itself in the venture capital industry through the level of “hands-on” technology expertise resident among its team of eight investment professionals and through the rigorous research, analysis and investment discipline it applies to each of its investments.

Strong Leadership

JK&B Partners are recognized in the industry as thought leaders, industry visionaries and highly sought after value-added Partners within their areas of expertise. The firm’s Partners through their previous executive positions have established an extensive network of industry contacts and proprietary relationships extending JK&B’s intellectual reach and offering its portfolio companies high level access to potential customers, strategic partners and financing sources.

Direct Access
