What is ZBee?

ZBee answers one question: how much can you safely spend per year in retirement?

It connects to your brokerage and retirement accounts read-only (or takes manual entry) and measures the maximum sustainable annual spend for the plan you actually have, with taxes, RMDs, Social Security timing, and sequence-of-returns risk (Guyton-Klinger style guardrails) in the math.

Everything computes locally: your holdings never leave your Mac, and the backend only brokers the read-only account connection. It measures rather than advises: no restructuring recommendations, one transparent assumption set, every assumption disclosed.

Free demo mode on sample data; ZBee Pro ($99/year, 30-day free trial) for your own data. Ships as a signed and notarized DMG.
