Supabase has raised $150 million in growth equity led by GIC, with participation from CapitalG, IronArc, and SquarePeg, and acquired Turso, a database company built for agentic workloads. The funding round arrives four months after Supabase's $366.7 million Series F.
Turso's architecture enables on-demand, per-agent databases without requiring a dedicated machine for each deployment—critical as AI agent fleets scale. The company already serves Superhuman and Mastra. Turso founder Glauber Costa will join Supabase as head of agentic services.
The timing reflects a sharp shift in database architecture economics. Supabase now adds over 1 million users and 4 million databases monthly, with 70 percent of new databases created by agents or other AI-driven tools. In June alone, the platform saw a reported 600 percent year-over-year increase in database provisioning, with agents responsible for the majority of new deployments.
The $150 million will fund product development for agent-focused database capabilities, with a portion reserved for employee liquidity—a signal that competing for GPU-era engineering talent requires tangible cash liquidity, not just equity.
The bet is straightforward: as AI agents write and deploy code, the backend market shifts from human-friendly developer tools to infrastructure optimized for machine-driven workloads at scale. Efficient database provisioning for autonomous systems represents a defensible moat in AI infrastructure, similar to how spot-instance markets and containerization became moats in prior cloud cycles.
