Higgsfield, a San Francisco-based AI startup that makes marketing and media content tools, said on Aug. 17 that it raised US$400 million in a series B round that valued the company at US$5.4 billion, more than four times its valuation around six months earlier.

DST Capital led the round. Growth Equity at Goldman Sachs Alternatives, Tribe Capital, and Intel Capital also participated, while existing investors including Accel, Menlo Ventures, and GFT Ventures joined the financing.

Founded in 2023, Higgsfield sells tools that generate videos, product shots, ads, and other short-form creative assets for brands, agencies, studios, and enterprise teams.

Its last disclosed financing was a US$80 million series A extension in January 2026, at a US$1.3 billion valuation.

By comparison, AI video platform Synthesia was valued at US$2.1 billion in January 2025.

The sector is also drawing scrutiny. In 2024, the US Federal Trade Commission announced a crackdown on deceptive AI claims and AI tools used to facilitate misleading content.
