We want to build an amazing spreadsheet.
We used to spend 10+ hours a day in spreadsheets on Wall Street and loved Excel.
With the introduction of AI, people have been seeking new ways to create spreadsheets.
Why can’t we leverage AI to build spreadsheets the same way people leverage it to write docs, PRDs, code, generate images and more?
So we decided to build it ourselves.
We know the bar is extremely high, and we hope to exceed it. It might take a while, but we're committed. We've been working on this for more than 4 years.
We hope you'll join us on this journey.
Give Subset a try and let us know what you think.
Engineering
Built on strong technology foundations
We've been building Subset for more than 4 years, and we're obsessed with performance.
- Rust-based spreadsheet engine
A fast and reliable foundation, suitable for large datasets, complex workbooks and maximum compatibility with existing spreadsheet formats.
- Custom sync protocol
Version history, offline editing, and realtime sync, built on an algorithm faster and more memory-efficient than CRDTs and OTs.
- Cross platform desktop app
Built on Tauri, a secure and lightweight application foundation that allows us to support Windows and Linux in the future.

Don't take our word for it
