Crunchbase News·low signal

The week ending March 27 saw $13.4B+ across the 10 largest funding rounds, led by OpenAI ($10B) and Shield AI ($2B at $12.7B valuation). Three of the ten went to AI-native vertical SaaS companies: Harvey ($200M legal AI, $11B), Qualified Health ($125M healthcare AI), and Dash0 ($110M agentic observability, $1B). Capital is concentrating in AI companies targeting specific verticals rather than horizontal platforms, with defense tech (Shield AI, Performance Drone Works) as the other dominant theme.
