Andy Grammer has a really similar sound. His song Build Me A Girl is one of my favorites. Jason Mraz is another one. I would recommend his new song I Won't Give Up. And Colbie Caillat is a girl with pretty much the same sound. Realize is my favorite by her. Also, you could try Lucky, it's an amazing duet by Colbie and Jason. Christina Grimme you might find interesting, she does covers of songs. She has an amazing voice, but no guitar, instead her weapon of choice is a keyboard. I really hope this helped
