About Us

Who We Are

Defiance is a leader in first-mover thematic ETFs designed to provide exposure to the emerging technology sectors defining the future.

We build ETFs around areas that are moving beyond themes and becoming distinct investable categories, from quantum computing and AI infrastructure to modern warfare and other emerging sectors reshaping global markets.

Our approach is built around purity of exposure: identifying these categories early and creating ETFs that give investors targeted access.
