Tamarack Global has closed a $72 million fund and is actively seeking space investment opportunities, having already allocated a third of the fund, including support for Impulse Space's $150 million Series B round. Co-founder Jamie Lee expressed a strong interest in early-stage companies, emphasizing a focus on concentrated investments due to the industry's high failure rate. The firm, based in Connecticut with a network in California, aims to invest in aerospace, robotics, data intelligence, and energy transition sectors.
