Svensson turned professional in the summer of 2019 and joined the Nordic Golf League, where he won the 2020 Race to Himmerland, the season finale in Denmark.[4] In 2021, he was runner-up in the season opener, the Lindbytvätten Grand Opening, and again runner-up at the Stockholm Trophy in June, one stroke behind Jesper Kennegård.
In August 2021, he was runner-up at the Finnish Challenge on the Challenge Tour, two strokes behind winner Marcus Helligkilde of Denmark.[5] The following week, he took a one-stroke lead into day three of the Made in Esbjerg Challenge, another Challenge Tour event, where he ultimately finished T10.[6] The results propelled him into the top 45 of Challenge Tour Rankings, earning exemption in category 3c for the fall tournaments on the tour.[7]
Svensson was again in contention at the Empordà Challenge in Spain. After a run of seven birdies in the final round he was co-leader with Julien Brun at the 16th hole, but a bogey-bogey finish sent him down the leaderboard to a tie for 3rd.[8] The result lifted him to 33rd place in the Challenge Tour Rankings, approaching a spot in the top 20 that secures a European Tour card for 2022, with two tournaments left of the season.[9]
Svensson finished the 2021 Challenge Tour season ranked 36th on the Order of Merit, enable him a few starts on the 2022 European Tour, from that season named the DP World Tour.
