Just imagine what you could do in an environment that nurtures you, values your opinions and embraces change as a Great Thing (tm). The job markets are in your favour these days. There are a lot of start ups and more established companies looking for people like you who obviously stand out. If I was you I'd start fishing to see what are my options in other places. One of these options will be something you just can't not take and your notice of resignation will be easier to hand out.
