Interesting and captivating are not exact substitutes. Interesting means that something holds your interest or makes you think. Captivating is stronger and means that something holds attention in a powerful way. By itself, the word "interesting" does not mean "boring" or "confusing," and it can offer sincere praise in many work settings.
What "interesting" doesn't tell you
"The client said the pitch was interesting."
This sentence reports the client's word. It does not prove that the client liked the offer, disliked it, or plans to accept it. Ask for direct feedback before drawing that conclusion.

See how Lyra Practice works →What "captivating" adds
Captivating gives clear and strong praise. It describes material that holds a person's attention. It does not promise approval, agreement, or a purchase.
"I found the pitch captivating, especially its opening customer story."
"Several audience members called her opening story captivating in their feedback."
The first sentence states the speaker's own view. The second reports feedback from the audience. Neither one claims to know what every person thought.
