The Insight Toolkit was initially developed by six principal organizations, three commercial (Kitware, GE Corporate R&D, and Insightful) and three academic (UNC Chapel Hill, University of Utah, and University of Pennsylvania). Additional team members include Harvard Brigham & Women's Hospital, University of Pittsburgh, and Columbia University. The funding for the project is primarily from the National Library of Medicine at the National Institutes of Health.

Many generous sponsors have supported ITK and the NLM continues to provide executive leadership in the project's administration. This project has been funded in whole or in part with Federal funds from the National Institutes of Health (NLM, NIDCR, NIMH, NEI, NINDS, NIDCD, NCI), the NSF, and the DoD (TATRC). Funding has primarily come under the direction of the National Library of Medicine, National Institutes of Health, under numerous contracts. Recently, the major revision to the toolkit, ITKv4, was made possible by NLM directed funds from the American Reinvestment and Recovery Act (ARRA).
