Frequently asked questions

How does Osage source proprietary deal flow?
The firm cultivates relationships with technology transfer offices and research labs across Mid-Atlantic and Northeastern universities, including Carnegie Mellon, the University of Pennsylvania, and the University of Maryland system.
