Will Bosi is a climber from Edinburgh in Scotland. He started out as a competition climber, first progressing through national competitions and then European youth comps where he had a string of podium finishes. He struggled somewhat to replicate the successes of the youth comps in the adult circuit, with his best performances being two 4th place finishes in 2019.
Since retiring from comps he has turned to sport climbing and bouldering outdoors, where he has been extremely successful. In 2020 he became the second British climber to climb 9b sport with his repeat of La Capella. He then replicated this success in 2021 with hard first ascents and repeats including among others:
Since 2022 he has focused more on bouldering, where he has also excelled. For example he flashed Charizard 8B+ and, as of 2024, has repeated four 9A boulders:

Alphane | 9A | Boulder | worked | 31st Oct 2022 | 9A (soft) |
Third ascent. Around 13 sessions. Easier than Honey Badger.
Before the first ascent Will had been playing on the boulder with Dave Graham and trying some of the moves. At the time the line seemed too futuristic so he didn't dedicate to it. After Shawn Raboutou made the first ascent Will got psyched on the line again and headed out with Aidan Roberts, initially just to try the line and then, when he made quick progress, to send it.
