Rebuild Tax
Canonical definition (Arco Lexicon)
The engineering cost of re-architecting a system built under MVP conditions when the business reaches meaningful scale — the deferred liability of every architectural shortcut taken in the name of speed.
Extended Definition
The Rebuild Tax is the hidden cost of the MVP model. When a startup builds for exploration — prioritising speed over permanence, iteration over architecture — every shortcut taken becomes a constraint on the business that eventually succeeds. The infrastructure designed for a hundred users cannot carry ten thousand. The codebase written for a product that was pivoting cannot support a product that has stopped pivoting. The debt arrives at the worst possible moment: when the business is growing and every engineering hour spent on reconstruction is an hour not spent on scaling.
