Cardboard

WellHired's take

“Cardboard is about as early and small as it gets - a 5-person, pre-seed YC company - but the founding team's specific background is unusually strong for this stage: Saksham was previously Co-founder/CTO of an EF-backed AI startup and has published at ACL, while Ishan spent ~5 years building performance-critical browser applications at HackerRank and built a Windows app with 5.7M+ downloads at age 14. Joining this early means genuine 0-to-1 ownership on a technically hard problem (a real-time video editor plus a reliable agentic AI layer, in the browser, simultaneously) - a strong fit if you want maximum ownership and equity upside at real technical-founder-quality company, but with all the volatility that comes with a team this size and stage.”

About Cardboard

Cardboard was founded in 2025 by Saksham Aggarwal and Ishan Sharma, backed by Y Combinator (W26 batch), headquartered in San Francisco. The company is building a browser-based video production system for growth and marketing teams and serious creators who need to ship videos consistently without long timelines or endless review cycles. Users upload raw footage plus a goal ("3 variants," "30s hook," "testimonials") and get a strong first cut in seconds that they can iterate on quickly - combining a high-performance in-browser editor with an AI agent that actually watches and understands footage to search across gigabytes of raw material, pull the right clips, sync to the beat, and source music, graphics, and sound effects automatically.

Become the default workspace for video production - the way Canva and Figma became the workspace for design - because it's collaborative, fast, and handles the tedious parts for you.
