TrashLab, the San Francisco-based AI-native operating system for waste haulers, raised a $12.0M Growth round led by early-growth equity firm Ventana with participation from existing investors Bienville Capital, Harlem Capital and CreativeCo, marking a follow-on financing rather than a first round. The company said it will use the funding to accelerate its product roadmap, expand its agentic workflows and grow its go-to-market team, with Ventana Co-founder and Partner Vinay Kumar joining TrashLab in a board capacity as part of the round. The announcement did not disclose specific metrics such as client count, revenue, pipeline or employee count.
