Marcus Eyers

Founder, Ember

Marcus Eyers is the founder of Ember, a multi-currency FIRE (Financial Independence / Retire Early) modelling tool for internationally-mobile people. He built Ember to answer his own cross-border questions — UK pensions, non-UK tax residency, capital gains across jurisdictions, and the timing of a move — with an engine that models the numbers rather than guessing at them. Every article here is engine-anchored and reviewed by a named human, not scaled AI content.

Marcus Eyers writes and reviews every article in Ember’s Knowledge Hub, published by Planespoken Ltd (company number 11084007).
