Who founded zero

The answer is : Pingala
He was an Indian mathematician.
His book Chhandah-shastra contains the first known use of zero.
Pingala presents the first known description of a binary numeral system. He described the binary numeral system in connection with the listing of Vedic meters with short and long syllables. His work also contains the basic ideas of maatraameru (Fibonacci number) and meruprastaara (Pascal's triangle).

Now there were many cases before of 0 being used (or something like 0), but this was the first fully recorded version of 0 in history.
