This research explores how entrepreneurs take defense mechanisms facing with possible risk of misappropriation of their own resources by established corporate “sharks” at the interfirm tie formations and during the relationships. Prior literatures have examined legal and timing defenses as well as social defenses in investment relationships. Conducting qualitative analysis based on interviews to entrepreneurs, we specified broader defense strategies including seven invisible defense mechanisms. We contribute to existing body of knowledge by showing the invisible defense mechanisms such as 'control of competitive state', 'resolution of information asymmetry', 'capability of idea execution', 'choice of composition' which seemingly cannot be seen as a defense mechanism.
