I’m Arnab Ray, an entrepreneur, startup mentor, investor and author with 18 years of experience in the startup ecosystem. Over the years, I’ve advised 2,200+ startups, mentored 350+ founders, served 5,000+ global clients and built 12 ventures of my own. This journey has given me hands-on experience across business strategy, idea validation, business models, go-to-market, growth, financial planning, fundraising and venture building. Through Array Ventures, I work closely with early-stage startups, helping founders move from idea to execution and build sustainable, scalable businesses. I also mentor entrepreneurs through startup ecosystems, incubators and institutions, and regularly speak and teach on entrepreneurship, startup strategy and fundraising. My approach is practical and evidence-led. I focus on helping founders identify what actually matters, challenge assumptions, make better decisions and avoid expensive mistakes. I’m also the author of *Survival of the Smartest*, published by Bloomsbury, where I explore why some startups survive, adapt and grow while others disappear. If you’re building a startup, validating an idea, preparing to raise funds, working through a strategic challenge or simply need an experienced second opinion, I’d be happy to help.
