"William" Jakrapatr Kaewpanpong, or William LYKN, is a quarter-American Thai singer, guitarist, pianist and main vocalist of the boy group LYKN (ไลแคน) signed under Riser Music (ไรเซอร์มิวสิค) and GMMTV (จีเอ็มเอ็มทีวี). He was previously a vocalist and guitarist in the band Broccoli (ผักเขียว). Originally from Hat Yai, he graduated from Mahidol University's Young Artists Music Program majoring in musical theatre and was a territorial defense student.
During the finale of "Project Alpha," William was named one of the show's winners, making it into Riser Music's first boy group. Two months later, on May 5, 2023, LYKN's debut single "May I?" (เลิกกับเขาเดี๋ยวเหงาเป็นเพื่อน) was released. His first solo single, "Last Twilight" (ภาพสุดท้าย), was released on January 5, 2024.
After William made his acting debut with a starring role in the short film "No Worries" (แอบรักไม่ทำให้ใครตาย) in 2023, he went on to book his first series with a starring role in "Thame-Po Heart That Skips a Beat" (เธม-โป้ Heart That Skips a Beat).
In May 2024, LYKN won Best New Artist at the 2024 Komchadluek Awards. In March 2025, they were awarded Best Boy Group of the Year at the 23rd The Guitar Mag Awards.
William owns an online fashion brand called Zaven (เซฟเฟ่น).
