Mirage, an AI foundation models company enabling video generation and editing, has raised $75M in growth financing led by General Catalyst. The capital supports development of proprietary multimodal models for short-form videos used by creators and businesses like HubSpot and Comcast. Funds will accelerate global expansion and agentic video capabilities.
AI Video Funding Frenzy Builds
The raise follows Synthesia's $200M Series E at a $4B valuation in January 2026, signaling investor rush into AI video tools. Mirage's non-dilutive growth financing from General Catalyst's Customer Value Fund targets post-product-market-fit scaling. This positions Mirage amid competitors like HeyGen ($74M raised) and Runway ML ($536M+), where custom models address gaps in accents and pacing.
Editing Time Drains Creator Productivity
Traditional video editing consumes one hour per minute of footage, per company data. Creators and marketers produce short-form content for social media, ads, and UGC at scale. Current tools lack seamless integration of generation, editing, and dubbing, slowing output for 20M+ users worldwide.
Proprietary Models Power All-in-One Editing
Mirage's Captions app offers chat-based editing, AI avatars, and auto-captions from text prompts or raw footage. Proprietary audio/video foundation models generate realistic short videos, preserving accents and emotions unlike general models. The Mirage API enables enterprise integration, powering 250M+ videos created and 3M+ monthly.
As Gaurav Misra, Co-Founder & CEO noted:
"Distribution and capital efficiency are the new defensibility."
Custom Audio Fills Accent Gaps
Mirage trained specialized models for short-video pacing, framing, and audio with regional accents. This differentiates from avatar-focused HeyGen or research-heavy Runway ML. Recent SOC 2 compliance bolsters enterprise trust for customers like King.
General Catalyst Backs Proven Economics
General Catalyst's Customer Value Fund provides non-dilutive capital for sales and marketing after PMF validation. Investors like Kevin Systrom highlight conviction in Mirage's trajectory, with prior $100M Series C bringing total to $175M+. Portfolio fits include Grammarly and Canva in AI content tools.
AI Video Market Scales Rapidly
The AI video generator market stands at $788.5M in 2025, projected to reach $3.44B by 2033 at 20.3% CAGR per Grand View Research. Trends favor custom models over general ones, as seen in Runway's Gen-4.5 release. Short-form explosion on TikTok and Reels drives demand.
Snap Expertise Drives Video Innovation
Co-Founder & CEO Gaurav Misra led Snap Spotlight, a TikTok rival, and Snap Map at Snap. Co-Founder & COO Dwight Churchill scaled operations at Klaviyo. The team attracts FAANG talent from Meta, Spotify, and Amazon post-rebrand from Captions in September 2025.
Hiring Fuels Agentic Expansion
Post-raise, Mirage hires web/product engineers in NYC with unlimited token budgets and agentic video roles. Plans target Asia via partnerships like Soundraw in Japan. Emphasis on enterprise suites merges web tools with the mobile app for global scale.
