The end of $3,000 enterprise licenses

If you work in BizOps or FP&A, you know the pain. You either buy an @RISK Excel license, write Python scripts, or manually hack RAND() functions until your browser crashes. MonteSheet eliminates the friction.

Ludicrous speed with zero cloud servers

Legacy add-ons send your data to slow cloud queues. MonteSheet temporarily clones your spreadsheet into your local browser memory. 100,000 iterations in seconds. Your data never leaves your machine.

Everything an analyst actually needs.

Without the enterprise bloat.

Tornado Charts

Spearman Rank Correlation instantly visualizes exactly which input is driving the most variance in your model.

Advanced Distributions

Unlock Log-Normal, PERT, Poisson, and Beta distributions required for accurate financial modeling.

Raw Data Exports

Dump the raw 100,000-row simulation matrix into a new Google Sheets tab for deep-dive pivot table analysis.

100% Local Privacy

No API calls. No cloud processing. Your proprietary cap tables and M&A data never touch our servers.

Seeded RNG

Auditors hate changing numbers. Use a seed string to guarantee your P50 result is mathematically identical tomorrow.
