Yep, in the financial district in San Francisco. Actually Lending Club (and Prosper which is just 5 blocks away) sit just outside what is typically defined as SF's financial district, which may have some symbolic justification as well. Makes sense these fin-tech companies are in SF which has loads of both financial and tech going on.
As for a man on the inside lol, I actually thought what the heck, why not wander by their office building. It is a highly secure building. Lots of companies in SF doing proprietary, important stuff but the building they are in is much more secure than the others. It has a sign saying as much. If you make loans or sell loans, I can see how you may have irate customers - it probably for the best having that kind of security. As an FYI, I was not trying to go inside.
As for the sailboat comment, whoosh- went right buy me - lol
