Arga Labs, an enterprise AI agent training platform, has raised $10 million in a seed round led by General Catalyst, with participation from Box Group, Emergence, Gradient, and SV Angel. The company builds digital twin training environments for enterprise software including Salesforce, Workday, and email clients. Arga Labs said its platform replicates permission systems and webhooks to address the difficulty of resetting enterprise software for large-scale reinforcement learning training and to support agent training across complex multi-system workflows. CEO and co-founder Philip Li said agent systems still struggle with cross-system information ambiguity, making Arga’s reproducible sandbox environment a key part of the approach.
