Cardboard - Agentic Video Editor

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.

It 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

We are building Cardboard - it is 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 us?

We met in middle school and have been best friends since the last 15yrs. We built Cardboard because we lived with this problem ourselves:

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

Both of us 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.

Ask

If you’re leading or working in a growth / marketing team that uses video as a distribution channel (launches, ads, recaps, testimonials, or weekly content) and you care about speed, we’d love to work closely with you.
