Is making a first step by sending a LinkedIn invite to my crush creepy?

I´m a shy person and I like an apparently shy guy. We just gaze at each other for quite a long time, without making any progress. I feel he likes me at least a little bit, but he is not approaching me at all.

Woudl it be creepy and show too much interest if I would send him an LinkedIn invite (not a Facebook invite, which is too personal)? I want just to start the conversation and know him better, not to catch and bed or even marry him :) :)
