At Defiance ETFs, we believe in the potential for technology to not only disrupt entire industries, but also dramatically change the way we work, play and live. Traditionally, investor access to these emerging technologies was limited to venture capital and initial public offerings. Now, through exchange-traded funds, it’s possible for any investor to tap into the key themes shaping our future.

Defiance ETFs was founded on the principal of giving all investors access to global, low-cost, targeted portfolios tied to transformative trends. Rooted in our distinct approach to disruptive investing, our ETFs empower investors to be on the leading edge of tomorrow’s biggest trends.
