Launch YC: Cardboard - Agentic Video Editor

"Edit videos at the speed of thought!"

TL;DR Cardboard is an agentic video editor. It gives you the power of Premiere Pro or DaVinci Resolve without the learning curve. It is orders of magnitude faster + cheaper than the old way of making videos.

Cardboard lives in your browser and helps you go from a sea of raw footage (talking heads, screen recordings, screenshots, B-rolls) to a great video in seconds.

Think of it as “vibe editing

The Problem

Video has become the default distribution channel for growth, marketing, and brand storytelling. The teams who iterate fastest on video, compound attention over time.

Many of us sit on mountains of raw assets - product walkthroughs, customer feedback, tweets, blogs, changelogs, emails, and newsletters - that should turn into testimonials, launch videos, recaps, and ad experiments.

But, editing is painfully slow. Getting to a first cut still means hours of manual work, expensive tools, and async feedback loops. This is where the momentum dies.

As a result, most teams ship far fewer videos than they should - not because they lack ideas or footage, but because the editing process can’t keep up.

The Solution

Cardboard - an agentic video editor that lives in your browser.

You can:

  1. Ask for a first cut (“make a 60s recap” / “cut this into ads”).
  2. Search footage by meaning, not filenames.
  3. Then refine it yourself on a timeline.

The goal is to make video production feel closer to modern design / coding tools - fast, accessible, and collaborative - so the teams can iterate fast and ship more.

Why Cardboard?

The founders met in middle school and have been best friends for the last 15yrs. They built Cardboard because they have lived with this problem themselves:

  • Saksham created content on Instagram and LinkedIn, with ~250k views/month on an average.
  • Ishan produced Apple-style internal launch videos for HackerRank’s all-hands demo days (350+ attendees) [Example: Video 1, Video 2].

Both of the founders hit the same wall: tools like Premiere Pro or DaVinci are powerful, but the learning curve is steep and getting to a first cut takes hours. Creativity starts to feel like manual work.

Cardboard exists to remove those painful steps - so that people can focus on what they’re actually good at: telling great stories.
