CROSS-CATEGORY: $1.56B in AI Infrastructure Mega-Rounds in a Single Week — Modal, Exa, Hark, Decart Signal Consolidation of the Agent Compute Layer

Crunchbase News·high signal

In the week ending May 23, four AI infrastructure companies raised a combined $1.56B: Modal Labs ($355M), Decart ($300M), Exa ($250M), and Hark ($700M). All four build different layers of the stack that AI agents depend on — compute (Modal), search (Exa), generation (Decart), and edge hardware (Hark). The concentration of capital signals that investors see the AI infrastructure layer consolidating around a few well-capitalized players, which has direct implications for SaaS builders: the compute/search/inference layer is becoming a utility with winner-take-most economics, not a commodity.
