From Station Master to Product Manager at PhysicsWallah

In short: I went from running about 2,400 freight trains a month as a Station Master at Indian Railways to becoming a Product Manager at PhysicsWallah, after declining an IIM MBA offer to keep building.

Building before the title

I'm Gautam Kumar. Long before I had "Product Manager" on my LinkedIn, I was building. From 2019 to 2021 I ran ReaderSpace, a WhatsApp news-analysis service that grew to 4,000+ members, 500 of them paying. From 2021 to 2023 I was an early Product & Growth member at MathonGo, helping scale the MARKS app to 100K+ downloads at 4.8★.

Alongside, I completed a BBA in Transportation Management at Gati Shakti Vishwavidyalaya.

A detour onto the tracks

In September 2023 I became a Station Master on Indian Railways' Dedicated Freight Corridor. Every month meant about 2,400 freight train operations, coordinated across 5+ departments, with no room for the wheel to stop.

It taught me things no product course does: operating at real scale, managing stakeholders under pressure, and deciding with incomplete information.

The fork in the road

Then came a choice. I had an MBA offer from IIM Sambalpur and a PGP offer from Mesa School of Business. I declined both. I wanted to learn product by shipping product.

Landing at PhysicsWallah

In 2025 I joined PhysicsWallah as Category Business Lead for IITJEE, a ₹320 Cr+ category, where attendance rose 4% and I shipped the PYQ Blueprint. Then I moved into product: I took Pi Lens App from 0 to 400K+ downloads and now drive product-led growth for PW Test Series.

What carried over

The railway taught me that systems at scale only work when every handoff is clear. That is most of product management: making sure the right thing reaches the right person at the right time, every time.
