> Who's Number One

Who’s Number One (WNO) — officially branded as the FloGrappling WNO Championship — is a professional grappling event series organized since 2019 by FloGrappling, a subdivision of FloSports. Headquartered in Austin, Texas, WNO presents elite no-gi and gi Brazilian jiu-jitsu matchups across men’s and women’s weight divisions, streamed exclusively on the FloSports subscription platform.

FloSports was founded in 2006 in Austin, Texas by Martin Floreani, Mark Floreani, and Madhu Venkatesan, originally as a streaming service for niche sports. FloGrappling became a significant force in professional grappling by commissioning WNO events and signing the sport’s top athletes to exclusive streaming deals. WNO events typically feature supermatches between elite grapplers rather than tournament brackets, giving the series a prestige-bout feel distinct from traditional tournament-format promotions. The series has featured athletes such as Gordon Ryan, Craig Jones, Ffion Davies, and Nicholas Meregali, positioning it alongside ADCC as one of the most prominent platforms in professional submission grappling.
