About Us

Nice to Meet You.

About-Us-Narrow

Hello! We’re Isabelle and Antoine.

In 2017, we sold our house (and everything in it), quit our engineering careers, and moved into our self-built campervan. Every day is an opportunity for a new adventure... We’re chasing our dreams, and hopefully it inspires others to do the same!
