California-based artificial intelligence startup Baseten, co-founded by Australians, announced a $1.5 billion funding round that values the company at $13 billion. The investment highlights the surge of capital flowing into AI firms, particularly those supplying infrastructure to commercialize generative AI.

The round was led by U.S.-based investors Sands Capital and Wellington Management. Australian venture capital firm Blackbird VC contributed what it described as the firm's largest-ever investment, without disclosing the specific amount. Baseten's software and infrastructure allow companies to customize their own AI models, offering a cost-effective alternative to providers like OpenAI and Anthropic.

Revenue growth has been substantial for Baseten, with the company reporting a 20-fold increase over the past year. This growth is driven by rising demand for inference, the stage where trained AI models generate outputs in real-world applications. The deal marks Baseten's fourth capital raising in 18 months, reflecting investor appetite for companies in this space.

Michael Tolo, partner at Blackbird, described the investment as a signal of conviction. He noted that the latest outlay may represent the biggest investment to date by an Australian venture capital firm. Tolo emphasized that Baseten competes with companies like OpenAI and Anthropic at a lower price point for businesses integrating AI into their tech systems.

This shift in unit economics and competitive leverage within the AI market is significant, according to Tolo. Baseten plans to use the funds to expand computing capacity, enhance software offerings, and increase hiring.


For companies building AI into their systems, Baseten's lower-cost alternative presents a competitive advantage. The company's growth trajectory and the substantial funding round reflect the broader trend of capital allocation toward AI infrastructure and services.
