Rework is the silent tax on “fast shipping”.
Flat 18 helps teams avoid it: clear requirements, sharp UX, senior engineering, fewer surprises.

Flat 18 helps teams start the week by doing the unglamorous work that pays in the long run.
If your week keeps derailing, it’s often planning, not velocity.

Shipping isn’t the hard part.
Shipping something you don’t have to apologise for later is.
