It bugs me when I hear an executive talk about 'doubling down' on an initiative. It's most often used to indicate that someone is redoubling their efforts in order to win, or that they're otherwise entering a 'make or break' period.

At the blackjack table, doubling down means to reduce your chances of success when you're in a good position in exchange for the ability to increase your bet. Doubling down when you're behind in order to catch up is a rookie move.

Things have been progressing quickly with a few other gorups we've been talking with. We're still very interested in working with A16Z (your reputation among those we've spoken with has been stellar) but we are getting a bit constrained with the timing. Would you be able to meet some time this week?
