The replay in the stream chat suggested that there were no more Founder's keys.
If you missed the anniversary sale, you missed a chance to catch up with us Founders at a real bargain. At that price, I gifted a copy to a family member. Now, if we can get his wifi figured out, I have the next best thing to hotseat. But keep your eye out for sales and it doesn't seem like it will be hard to keep up.
