Welcome to Founder Real Talk, a podcast for founders, by founders.
We explore the real journey of building and growing a company. Each episode, we go beyond the highlight reel to unpack the strategies, decisions, and hard lessons that shaped successful businesses, revealing the good, the bad, and the ugly behind the growth. In this episode, Josh sits down with Malur Narayan, CEO of Xtrium, a startup leveraging quantitative AI and graph networks to fix critical manufacturing supply chains. Malur breaks down why China's 95% chokehold on critical raw materials impacts everyday American products, how he transitioned from managing thousand-person corporate teams to working 16-hour days with no salary, and why surviving as a founder requires embracing the reality that 99% of incoming news will be rejections.
