Dear potential sponsors, My name is Pieter Buist I am a professional athlete in MMA in the Lightweight division who lives in the Netherlands Breda. I am is 2nd ranked of 114 active fighters in Southeast Asia and 4th ranked of 572 active fighters in Western Europe. I hold a record of 17 wins, 4 loses and 0 draws. Within these 17 wins he holds 4 titles; 2 times FIMAC European Champion 77kg, SHC European Champion 70 kg, and World Champion of WFL “World Fighting League” 70 kg. After winning the WFL world title I was given the opportunity to show my talent within "ONE Championship". ONE is Asia’s largest global sports media property in history, with a global broadcast reach of 2.7 billion potential viewers across 150+ countries. They also achieved some of the highest TV ratings and social media engagement metrics across Asia with its unique brand of Asian values. The events are held in the largest stadiums in the most iconic cities across Asia. Due to his spectacular fighting style and undefeated streak in his last 8 matches, he became one of the popular fighters within ONE. On top of that Pieter is also announced as one of the best looking fighter in the organization. The mission of ONE is to unleash real life superheroes who ignite the world with hope, dreams, inspiration and strength. This mission suits me as no other, as a fighter and as an inspirator. My history has inspired many. Where I grew up in a tough neighbourhood, from being homeless to becoming a garbage man and now candidate. After defaulting a former ONE Championship world champion, to become the world champion for the biggest MMA organization in the world. I am also ambassador for children that cannot afford to participate in sports. With this task I managed to get the funds for a large group of children who are now able to do the sports they love the most. The reason I reach out to you is to see if there are any possibilities regarding sponsorship. I am aware of the large opportunities that are among us. The reach of ONE is major which means that your brand is able to conquer not only south-east Asia where the fights are held, but also all the 150+ countries where the fights are broadcasted. These are broadcasted via the highlight-clips on social media, and in the ONE app. Next to this market I own a fanbase in the Netherlands which reaches out to through his social-media. The chances/possibilities for you lays in the worldwide advertisement and brand expanding. With this perfect match I am confident that I can help your company to create new leads/prospects and increase opportunities for existing customers in the market worldwide. If you are interested I would like to hear what you can offer to contribute to making the “brand” Pieter Buist bigger than it is now. If we would team up in his mission to become the ONE world champion, the benefits for both parties would be big. I hope to inspire you with this as I inspires the people in my environment. Thank you.

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.
