We met Andy awhile back because of his domain expertise and wanted to learn from him - never thought of approaching him for angel investment. He has been very helpful pointing us to the right direction when needed, and overtime, he decided to also be an investor and we could not be more thrilled! Andy is extremely thoughtful and down to earth. He's supportive of entrepreneurs (because he is one, not 'was one', so he understands what we're going through and still 'gets' it).
We feel lucky to have him on our team very unexpectedly as an investor. Do anything you can to get his attention!
