AI Video Unicorn Higgsfield Raises $400M, Aiming to Become Marketing’s New Infrastructure

San Francisco–based generative AI video startup Higgsfield has raised a fresh $400 million round at a post‑money valuation of $5.4 billion, according to investor newsletter reports. The company builds workflow‑oriented tools that let marketing teams and creators generate short‑form ads and social clips using a mix of large language models and image/video generation models.

Founded in 2023 by former Snap generative AI lead Alex Mashrabov and co‑founder Erzat Dulat, Higgsfield launched its browser‑based product in 2025 and has grown quickly as brands shift more ad spend into AI‑produced video. Earlier this year the firm was valued at just over $1.3 billion after an extended Series A, making the latest round a major step‑up that firmly places it in “mega‑unicorn” territory.

For advertisers, the appeal is clear: instead of traditional shoots that take weeks and large budgets, teams can iterate dozens of variants in hours, testing different visuals, scripts, and formats. Industry observers increasingly describe tools like Higgsfield as emerging “infrastructure” for modern marketing. At the same time, rapid advances in image and video generation continue to raise tough questions around copyright, performers’ likeness rights, and deepfake abuse. The new funding highlights both the commercial momentum behind AI‑driven creative production and the urgency of parallel work on standards and regulation.
