Girish Manghani

I'm a FinTech Product Leader at Fidelity Investments, where I own the strategy and transformation of digital investing, trading, and financial planning experiences — products that help millions of customers take meaningful control of their financial future.

With more than a decade in product management, I've built my career at the intersection of strategy, finance, business, and design. My teams build the award-winning apps and websites that power Fidelity's digital presence, supporting over 30 million active users, delivering consistent revenue growth, and maintaining a steady 5-star customer satisfaction rating — with rock-solid stability and resiliency.

As a people leader, I champion an inclusive culture and build cross-functional organizations that compete aggressively and win top industry awards. I believe the best products come from teams that feel safe to challenge assumptions, move fast, and care deeply about the people they're building for.

Why this site?

Product management is changing faster than any point in the discipline's history. AI isn't just a new tool — it's reshaping the entire job: how we discover, how we build, how we decide, and how we lead. I started this site because I couldn't find a single destination for substantive, practitioner-level thinking on what that means.

My goal is to write clearly about what's actually changing, what it means for PMs at every stage of their career, and how to navigate the shift intelligently — whether you're a seasoned leader trying to stay sharp, a junior PM building your foundation, or someone making the move into product for the first time.
