The right operating model
Define entities, calculations, states, permissions, and decisions before polishing screens.
Software around the work / 11
Build the tool your workflow is already asking for.
When spreadsheets, disconnected apps, and manual checks start hiding the real picture, Crelyvo prototypes and builds a focused operational product.
Who it is for
For operations that have outgrown disconnected spreadsheets or generic tools and need a focused product around real entities, calculations, permissions, approvals, and decisions.
What the system needs to solve
A testable sandbox
Validate formulas and interactions with synthetic data before introducing production risk.
A maintainable product
Plan hosting, security, observability, ownership, and change management as part of the build.
Decisions that matter
Designed around the real work.
What deserves software
Identify the costly coordination or decision problem rather than rebuilding every existing spreadsheet.
Model before interface
Define entities, states, formulas, permissions, and audit needs before polishing screens.
Release responsibility
Plan ownership, backups, monitoring, access changes, and safe deployment as part of the product.

FAQ
Can we test calculations before development?
Yes. The four public software sandboxes demonstrate the value of validating formulas and decisions first.
Does custom software need to replace every spreadsheet?
No. The goal is to solve the costly coordination problem, not rebuild useful tools without reason.
