"YG came highly recommend by colleagues of mine that works for large CE brands, as someone who embraces projects from both large corporations and startups alike (after all, weren't all large corporations startups at one time?).

YG gets it, at each stage of our startup project he always acted as a partner in our entrepreneurship, never "just a vendor".

I am not just happy to work with Alan as my partner, I am truly and deeply grateful for it."
