Gaurav Marballi

Chief Digital & AI Officer @ JGW | Author of “AI Inference with Ollama” | Harvard MBA

About

At JGW, I am leading our transformation into a truly data-driven organization, where AI + analytics is not a support function, it is the operating system for the entire business.

I have built and scaled analytics organizations across travel (Priceline), publishing (Barnes & Noble), financial data (S&P Global), and consumer financial services, proving that when technical excellence meets business acumen, data becomes a core asset that improves ROI.

Fluent in business and technology (Harvard MBA + Computer Science), I believe the future belongs to leaders who can bridge both worlds.

Impact Areas

  • Scaled analytics from zero to enterprise scale across five industries
  • Built teams that shape outcomes, not only report metrics
  • Architected data products that became core revenue drivers
