Weekly AI: agent infrastructure draws capital while foundation-model economics get repriced
The week's deal flow shows where investors are placing the next tranche of AI capital. Rillet raised a $100 million Series C at a $1 billion valuation after a single board update, Instinct reached a $2.5 billion valuation four months after founding, and Socure closed $156 million while absorbing agentic-AI compliance startup Fravity. Infrastructure plays drew comparable attention: Agentrys raised $24.5 million for chip-design agents, Keenable raised $26 million for an agent-optimised web index, and Arga Labs raised $10 million for agent sandboxes.
