Kaz, a seasoned finance skilled primarily based within the U.S., agreed to co-found Fillgoo. He now serves as the corporate’s CEO, whereas Grover focuses on advertising and marketing and promotion as chief advertising and marketing officer.
“Enterprise was by no means my sturdy swimsuit,” Grover laughs. “However when my brother stated he noticed actual potential and supplied to take this journey collectively, I assumed — if he’s main the way in which, I’m in.”

Household has all the time been central to Grover’s story.
