The 25-year-old has linked up with the Glovers after seeing his contract run out at Wycombe Wanderers.
He had various options to consider after dropping into the free agent pool, with a number of second tier sides prepared to put terms to him.
Grant admits he discussed a move to Portman Road with Ipswich boss Mick McCarthy, but is delighted to have made his way to Huish Park.
He told the Western Gazette: "There's been a bit of interest, so I've heard from my agent. I was lucky enough to meet Mick McCarthy and he's an excellent manager.
"But, at the end of the day, Yeovil have shown a keen interest right from the beginning of the close season and it's one that I have decided to take them up on.
"I know it's going to be tough for everyone, but we will all give it a good go and that is something I want to be part of - trying to keep Yeovil in the Championship.
"It was the work ethic of the team that attracted me, as well as the fact they earned promotion last season and the manager (Gary Johnson).
"Speaking to him reminded me of Gareth Ainsworth at Wycombe Wanderers, because he's strong on work ethic and it's something I have improved in my game in recent years."
