New ventures face a trade-off when considering corporate venture capital (CVC) funding. Corporate investors can provide complementary assets that enhance the commercialization of new venture technologies. However, tight links with a particular corporate investor has drawbacks and may constrain new ventures from accessing complementary assets from diverse sources in an open market. Taking this trade-off into account, we explore conditions under which CVC funding is beneficial to new ventures. Using a sample of computer, semiconductor, and wireless ventures, we find that CVC funding is particularly beneficial for new ventures when they require specialized complementary assets or operate in uncertain environments.
