DETERMINISTIC · ALL 10 PROVINCES

Engine

Every number, engine-verified

A deterministic engine computes your plan the same way every time — federal and provincial tax across all ten provinces, including Quebec and QPP. The Optimizer proposes candidate strategies, but only reports numbers the engine actually computed. Nothing is invented by a language model.

Paycheque

Your retirement paycheque

In retirement, your dashboard becomes a paycheque view — showing exactly which accounts to pull from, how much to withdraw, and when. Retirement income, simplified.

Built in Canada

The math is the proof.

Slackwater is bootstrapped and independently built in Canada. There's no sales team and no marketing spin — just an engine you can trust. It's a deterministic projection engine that computes your plan the same way every time, with tax accuracy across all ten provinces, including Quebec.

The Optimizer works on the principle that the agent proposes and the engine verifies. It only ever reports numbers the engine actually computed — never a figure invented by a language model. Every result you see is one the engine can reproduce.
