Congrats on the initial traction. I asked this in your Show HN thread, and I'll ask again: where did you get the list of emails belonging to "over 350 million professionals?" This is clearly your main value-add and the reason people are paying you money. But was the data legally sourced? This is the first question any competent VC will ask, and you better have a damn good answer to it, especially in today's political climate around personal data.
