Higgsfield, an AI image and video generation platform, raised $400 million in Series B funding at a $5.4 billion valuation, according to the company's announcement. The round quadruples the company's Series A valuation of $1.3 billion set in January 2026.

Generative AI tools capable of producing visual media at scale continue to attract venture capital. Higgsfield now reports $700 million in annualized revenue, a figure that places the company among a narrow band of AI startups achieving nine-figure annual run rates within two years of Series A. The valuation-to-revenue multiple sits at 7.7x, higher than many infrastructure-layer AI plays but in line with application-tier generative tools that have commanded venture multiples above 5x.

Founded by Alex Mashrabov, formerly a product executive at Snap, Higgsfield positions itself in direct competition with Runway, Pika Labs, and OpenAI's video capabilities. The company's focus on user-facing creation tools rather than API-only access has driven the revenue scale. Mashrabov's background at Snap, where he worked on visual product development, informs Higgsfield's design philosophy around image-first interfaces.

The Series B was led by Goldman Sachs and DST Global, according to reporting on the funding. Other participants included existing backers from the Series A. The capital will fund product development, infrastructure scaling, and go-to-market expansion, the announcement states.

Higgsfield's valuation moved from $1.3 billion to $5.4 billion in seven months. A 4.15x valuation increase in this timeframe is rare outside the consumer AI space, where user adoption curves have driven both top-line growth and fundraising cycles. Most Series B rounds in the broader AI infrastructure sector see 1.5x to 2.5x valuation bumps year-over-year.

The company's $700 million annualized revenue is the metric to track. If Higgsfield sustains that run rate through the end of 2026 and into 2027, the valuation-to-revenue multiple will compress further and reshape venture expectations for Series C pricing in the generative media category.
