Self-Managed
William Marshall is a rising South African karting talent from Cape Town, competing with Ward Racing and building momentum on the FIA karting stage. With a clear F1 trajectory, strong race results, and a highly sponsor-friendly youth motorsport profile, he offers brands a compelling mix of performance, ambition, and authentic reach in the racing community.
I am a 15-year-old South African racing driver building a pathway from international karting into Formula 4 and the European single-seater ladder. My social audience is growing quickly, with Instagram approaching 50,000 followers and the United States now my largest audience market. I offer sponsors a combination of race-weekend storytelling, digital content, motorsport credibility, kart/racewear branding, behind-the-scenes access and long-term ambassador value as my career develops. I have won South African and African karting titles, earned Protea Colours for motorsport, finished 2nd overall in the Champions of the Future Academy programme, took pole position at the FIA OK-N World Cup and have been selected for the Richard Mille Young Talent Academy Shootout. My story is about carrying South African racing talent onto the international stage. I am currently racing with Ward Racing internationally, preparing for Formula 4 testing and building toward European F4 competition. I am looking for partners who want to support ambition, performance, discipline and the journey of a young driver from South Africa chasing the international racing ladder.

Genisys Credit Union, headquartered in Auburn Hills, Michigan, has done something most brands never do with athlete sponsorship: it kept renewing. What started as a single partnership with Detroit Lions tight end Sam LaPorta has become a multi-year, two-athlete program that Genisys has renewed and expanded every season since 2024, adding Lions wide receiver Isaac TeSlaa in 2025 and renewing him again in 2026.
