Hey,
When you see that your company is not growing much, talk to your higher authority so that you can try to share some valuable piece advice to him for the growth.
Do not think to leave so early, rather think like if you can do something good for your company you will be recognized and get appreciation which is very rare in companies.
And if it is at all not working, then you can think of switching. Otherwise, without doing any good to your company do not leave it.
