Mirage (Formerly Captions) Secures $75 Million to Lead AI Short Video Editing

The popular AI video subtitling application, Captions, has undergone a significant transformation, rebranding as Mirage. The startup is repositioning itself as an AI lab specializing in video editing, with a new ambition to develop proprietary models rather than merely integrating third-party APIs. This strategic pivot is supported by a $75 million funding round led by General Catalyst’s Customer Value Fund.

Models Tailored for Short Videos

While many AI video editing tools focus on generating content from scratch, Mirage zeroes in on the day-to-day needs of creators and marketing teams: assembling, framing, pacing, and localizing videos. The company has developed a model specifically trained for framing and optimizing attention dynamics within short-form videos, recognizing that the first three seconds are critical for viewer engagement in today's fast-paced digital landscape.

CEO and co-founder Gaurav Misra describes their methodology as "assembly intelligence." Rather than relying on a single monolithic model, Mirage combines specialized systems to accelerate creation while preserving essential editorial control.

The Importance of Preserving Accents

A key development underway is the creation of an audio model capable of preserving original accents in generated videos. Most existing text-to-speech solutions primarily offer a neutral, often American, accent, which frequently falls short of the expectations of international creators.

Impressive Figures in a Crowded Market

Despite a highly competitive market, the Captions application achieved remarkable success, with over 3.2 million downloads in the past 12 months and generating $28.4 million in in-app revenue, according to Appfigures. More than 200 million videos have been created on the platform.

These compelling statistics clearly swayed General Catalyst. Pranav Singhvi, Managing Director of CVF, noted that "Mirage's economic equation is perfectly mastered. They know exactly how to spend a dollar and generate an attractive ROI."

Positioning Between CapCut and Enterprise Tools

Mirage is entering a seemingly saturated market, dominated by consumer apps like CapCut (ByteDance) and Edits (Meta) with their aggressive freemium models and massive distribution. Other players like Canva, D-ID, HeyGen, Webflow, and Avataar also occupy various segments.

Mirage aims to bridge the gap by merging its mobile editor with its web marketing suite. This strategy targets small businesses that need to produce numerous videos from a single integrated environment. The startup is also focusing on rapidly growing Asian markets, which further justifies its investment in sophisticated multilingual audio models.
