Construct Capital has successfully closed its third fund, raising $300 million to invest in early-stage startups focused on defense and manufacturing technologies. This marks a significant increase from their previous $225 million fund and a $75 million pool for later-stage investments. The firm, founded by Dayna Grayson and Rachel Holt, is capitalizing on rising institutional interest in defense tech amid geopolitical tensions. Notable investments include Hadrian and Veho, which specialize in software manufacturing and last-mile delivery, respectively. This funding reflects a broader trend of support for innovative tech in critical sectors.
