IEF is a Dutch VC investment fund founded by Randolf Nijsse and Siemon van den Berg. They provide more than just capital, acting as a sparring partner to exchange ideas and share knowledge. IEF partners invest their own capital, making calculated risks and ensuring fast decision-making. They have no predefined investment criteria or exit pressure, and are willing to invest for an indefinite period. IEF can be the lead investor or co-invest alongside like-minded partners, with a typical initial commitment of €250k to €1m.
