Advice: OK to pursue a guy if he's 'seeing someone'?

There is a guy I'm interested in, and I want to get to know him better. We have had a few conversations about basic business or networking. A friend of mine recently had a conversation with him and he shared with her that he is "seeing someone" and broke it down to say to her, "He's investigating that possibility still and is willing to go there if his investigation yields promising results" in regards to the girl he's seeing. My question is, would it be wrong or leading myself astray if I still attempted to get to know him and possibly pursue something romantic? I don't know him as well as my friend, so we have not had any personal or romantic discussions. I just know he seems like a great guy, attractive and has great values, and I really wanna see if I can take it there. I'm just wondering if I'm wasting my time since he is "seeing someone."
