A genuinely useful free tier, and Pro at £99 a year — about one consultant-hour, annually. No seats to count, no quote to chase, no procurement saga.

Desktop risk suites are typically thousands per seat per year, behind a demo call. Excellent tools — priced for organisations, not analysts.
The whole analysis runs client-side. No servers crunching your schedule means no server bill baked into your subscription — and no upload for your security team to review.
£99/year is under the line where individual analysts and small consultancies need approval. Monthly-cycle QSRA should be a habit, not a procurement event.
Yes. The licence is a signed key, not an account — paste it into the app on any machine and it activates there too. It's verified in your browser and works offline.
The subscription renews through Stripe and your key's expiry extends automatically. If you cancel, Pro simply lapses at the end of the paid year — the app drops back to the free tier, and every file you've saved keeps working.
If Pro isn't right for you in the first 14 days, email hello@runmontecarlo.com and we'll refund it, no forms.
Nowhere. Import, simulation and reporting all run in your browser; your files never touch our servers. The only network calls are checkout and one-time licence activation. The in-app guide (Help button) has the full privacy model.
Stripe emails a receipt automatically at purchase. Need a formal invoice with your company details or VAT number on it? Email hello@runmontecarlo.com and we'll issue one.
Today it's one key per analyst at £99 each — for a team of five that's still less than one day of one consultant. If you need white-label reports or 10+ keys, email us and we'll sort something sensible.
No trial clock, no card required — the free tier doesn't expire.
