25-year-old Dobey is aiming for a place in the world’s top 50 and a spot at the dart’s world championship.
This year Dobey reached the last 16 of three consecutive Players Championship tournaments and came close to shocking world number one Michael van Gerwen in the quarter-finals of the German Darts Masters in March.
Hunt, 22, is having a good year on the PDC Development Tour.
He’s won one tournament, reached the final of another event and made two quarter-final appearances.
Hunt is currently in third place on the Development Tour Order of Merit.
According to Unicorn stablemate and double world champion Gary Anderson, Dobey and Hunt are both capable of making a big impression on darts.
Anderson adds: “The link-up with Unicorn will help that process.
“They are both cracking players and cracking lads and deserve all the success that’s going to come their way.”
Unicorn player liaison Matt Rankin says: “Both are hugely talented players and we look forward to assisting their development over the coming months and years.’’
