Shofo

The World's Largest Video Library. We are building the world’s largest video library. We've aggregated billions of videos into a searchable index and use agents to find and label the exact datasets a lab needs on demand. If a lab needs 100K hours of cooking videos where someone is holding a pan, with reasoning annotations on top, our agents search the index, extract the matching subset, route it through our labeling pipeline, and deliver a custom dataset in days, not months.

Cardboard

Agentic video editor. Cardboard is an agentic video editor for growth/marketing teams and serious creators who need to ship videos consistently. Instead of agencies, long timelines, and infinite review cycles, teams give cardboard a footage + a goal (“3 variants”, “30s hook”, “testimonials”) to get a strong first cut in minutes on which they can iterate quickly. Multimodal LLMs can finally reason over footage, and WebGPU/WebCodecs make a real NLE possible in the browser. For the first time, an “AI director” inside a professional editor can be a reality. We have to build two hard things at once: a high-performance editor in the browser and an agentic editor that is reliable for production use cases. Most startups do one; incumbents can’t rebuild their stack without breaking everything. Saksham and Ishan met in school and have known each other since 15 years. Saksham was Co-founder/CTO of

Wideframe

AI coworker for video editors to ship more video faster. Wideframe is an AI coworker for video editors. It automates the searching, labeling, organizing, and sequencing of footage so editors can ship videos faster. Why is this important? Well, it turns out that editors spend 3x more time preparing footage than actually editing. One agency said we will save their editors 10 hours per week. Another organized an entire documentary worth of footage in hours rather than weeks. He had 2,500+ videos, 500+ audio clips, across >2.5 TB of files and our agent handled them effortlessly. Users link footage to Wideframe and then our Agent acts like an Assistant Editor to handle work like searching, labeling, organizing, and sequencing footage. Wideframe works with footage across local filesystems and cloud providers. We also supports Adobe Premiere Pro (.prproj) roundtrip. Our robust integrations are

cocreate

video production software. Cocreate was built alongside our friends and colleagues — editors and their assistants, DITs, post supervisors, and UPMs — to design something that will keep individual professionals competitive in a landscape rapidly overrun by needless automation. We've spent the past few years collecting as many grumbling stories of production and post production inefficiency; lost footage, wasted time. Shots un-slated, timecodes un-jammed, script supervisor notes incoherent; days wasted on menial tasks. What if there was a tool to take care of all that?

Synthetic Society

Synthetic Videos to Simulate Real Users.
