Since 1997, the BIRD (Binational Industrial Research and Development) Foundation works to encourage cooperation between Israeli and American companies in various areas of technology, and provides free assistance in locating strategic partners from both countries for developing joint products. The BIRD Foundation supports projects without receiving any rights in the participating companies or in the project itself. The financial assistance is repaid as royalties from sales. The Foundation provides support of up to 50% of a project's budget, beginning with R&D and ending with the initial stages of sales and marketing. The Foundation shares the risk and does not demand that the investment be repaid if the project fails to reach the sales stage.
