Free evaluation

Send us a spreadsheet or a program. We'll show you its Pebble Stream equivalent.

A critical workbook, a COBOL batch job, a SQL procedure: we'll rebuild its rules as a governed Pebble Stream workbook and prove it gives the same results as the original.

  1. 1Tell us about it. What it is and what it does. We'll confirm your email.
  2. 2Accept our evaluation terms online, in about two minutes. Prefer your own NDA? Send it to us.
  3. 3We confirm within one business day and email you a private, secure upload link.
  4. 4Upload, and choose how long we keep it. Your files are deleted automatically when that time is up, or the moment you ask.

What happens to your files

  • Stored encrypted in a private container for the region you choose, and scanned for malware on arrival
  • Kept and processed in that region: the US (Claude hosted on Azure) or the EU (Claude through Amazon Bedrock in Frankfurt), and never used to train AI models
  • Deleted automatically on the date you choose, or sooner on request
  • Seen only by the engineers working on your evaluation

What you get back

The Pebble Stream workbook

Its rules as worksheets and formulas, with PebbleScript notes your team can read in Excel.

Proof it matches

The original and the workbook run on the same inputs, compared field by field, with the results inside the file.

A short findings note

What we found along the way: hidden assumptions, fragile steps, defects worth knowing about.
