From Captions to Mirage: The $75 Mn Bet on AI Video’s Next Frontier

General Catalyst’s Customer Value Fund (CVF) has provided $75 million in growth financing to Mirage, the business behind the popular video editing tool Captions. However, this is more than simply another funding round; it represents a shift in the company’s self-perception and its place in the AI ecosystem.

The firm changed its name from Captions to Mirage as part of a strategic change during the last year. The change signals a transition from a video editing tool to a full-fledged AI lab with an emphasis on developing sophisticated models. Mirage currently aspires to be at the nexus of intelligence, automation, and creativity, supporting large businesses like marketing and advertising as well as individual producers.

Building AI That Understands Attention

One of Mirage’s most intriguing developments is its proprietary AI model trained specifically for short-form video dynamics. In a world dominated by reels, shorts, and quick-scroll content, understanding pacing, framing, and viewer attention is everything.

Mirage’s model is designed to optimize exactly that—helping users create videos that not only look good but also retain attention. This gives it a competitive edge in a space crowded with tools that focus primarily on editing, rather than engagement science.

The company is also exploring what it calls “assembly intelligence”—a concept that hints at the future of automated video creation. Instead of manually editing clips, users could soon rely on AI to assemble complete videos from multiple inputs—text, visuals, audio, and more—into a cohesive final product.

Competing in a Crowded Creator Economy

Mirage’s evolution comes at a time when competition in the video creation space is intensifying. Giants like ByteDance with CapCut and Meta with Edits are aggressively expanding their offerings.

To stay competitive, Mirage made a crucial shift in January 2025—moving to a freemium model. This allows users to access basic features for free while charging for premium capabilities. The strategy not only lowers the barrier to entry but also aligns with how modern creator tools scale globally.

Beyond individual creators, Mirage has also launched a video-creation suite tailored for businesses. This platform allows companies to produce and distribute videos in bulk—an increasingly important capability in the age of performance marketing and content-driven growth.

Solving for a Global Audience

A standout aspect of Mirage’s strategy is its focus on international users. According to the company, only about 25% of its revenue comes from the U.S., highlighting a deeply global footprint.

This global focus directly influenced the development of its new audio model—one that preserves accents in AI-generated videos. CEO Gaurav Misra shared a personal anecdote about how existing tools often “Americanized” accents, even when users spoke in their native tone.

By addressing this gap, Mirage is tapping into a subtle but powerful aspect of content authenticity. In a world where creators want to sound like themselves—not a generic voice—this feature could become a major differentiator.

Strong Traction and Growing Scale

The company’s growth metrics reinforce its rising influence. Over the past year, Captions has been downloaded more than 3.2 million times and generated $28.4 million in in-app revenue, according to Appfigures.

Even more impressively, the platform has been used to create over 200 million videos. These numbers point to strong product-market fit and a rapidly expanding user base across geographies.

Such traction likely played a key role in attracting funding from General Catalyst’s CVF, which focuses on scaling companies with proven customer demand and monetization potential.

What Comes Next for Mirage?

Looking ahead, Mirage plans to unify its offerings by merging its web-based marketing suite with its mobile-first editing platform. The goal is clear: create a seamless ecosystem that caters to both creators and small businesses.

This integrated approach could unlock new use cases—especially for small businesses looking to produce high-quality marketing content without large teams or budgets.

At the same time, Mirage’s continued investment in AI models suggests that the company is betting big on automation-led creativity. If successful, it could redefine how videos are made—shifting from manual editing to intelligent assembly.

The Bigger Picture

The transformation of the creative economy from tools to intelligence platforms is reflected in Mirage’s story. The winners will probably be those who actively foster creativity rather than just facilitate it when AI becomes a key component of content creation.

Mirage is establishing itself as more than just another editing tool thanks to new funding, a defined mission, and an expanding user base worldwide. It wants to be the driving force behind the upcoming wave of video content.
