Software the bank can stand behind.

Parsiy is the internal development unit of GN Bank. We design and run the systems behind the bank's daily work: quiet software, plainly documented, built to the same standard as the workpapers it produces.

simplification + automation = transformation

The name

parsev.
To resolve a thing into its parts; to think clearly about what is actually there before acting on it.
parsimonyn.
The principle that the simplest sufficient explanation is the right one. Pick it, then act.

How the unit works

We build for a bank, so we build like one. Every system ships with its own documentation, prints to a clean page, and states its status in words rather than color alone. Document first: a screen should read like a defensible workpaper. Evidence, dated: a claim about a system carries the day it was last observed true. Parsimony throughout: when two designs both work, the simpler one is already finished.
