The week's largest U.S. startup funding rounds were led by two $400 million cybersecurity deals, according to Crunchbase's latest roundup. Island, a Dallas-based enterprise security firm, raised Series F financing led by Evolution Equity Partners, setting a $6.4 billion valuation—more than double its 2024 figure. Cyera, a New York data security company, also secured $400 million in Series G extension funding, bringing its total raised to $2.7 billion.
Beyond cybersecurity, several AI and health-related startups attracted major capital. Snorkel AI, which builds tools for specialized training data, raised $350 million at a $3.2 billion valuation, with annual recurring revenue exceeding $375 million. Enveda, an AI-enabled drug discovery company, closed a $311 million Series E, and Precision Neuroscience, a neurotech startup, took in $250 million for its brain-computer interface work.
Other notable rounds include Hubble Network's $200 million for satellite-based Bluetooth connectivity, Rightway's $155 million for pharmacy benefits, and three $100 million deals: Rainmaker for cloud seeding, Numeral for AI-powered tax compliance, and Micro1 for AI training data. Crunchbase notes that Micro1's round is based on a Forbes report and has not been officially confirmed, making it the only deal in the top ten without direct verification from the company or investors.
