About

How I think about product

Great product work happens across three dimensions at once — betting on which customers and markets are worth the company's attention, experimenting your way to the right solution before committing to build, and shipping fast enough that real users tell you if you got it right. I've spent six years doing all three.

I started at a small, bootstrapped construction SaaS startup in India. Construction is not a normal software market — decisions happen on site, across owners, contractors, and project managers who all see the problem differently. 100+ visits taught me how to navigate that — and find the real problem underneath all of it.

From there I joined a US based, venture-funded growth-stage startup — where, under a strong product leadership team, I learnt what great product management actually looks like and grew from Product Owner to Product Manager over three years. Each step was a harder problem: first bringing reliability to how the team shipped, then using discovery to get customers to value faster, then owning the business problem of retention end to end.

I'm now at HHL Leipzig doing an MBA — adding business depth to product judgment. I'm building ventures alongside my studies, one in an EIR program at a climate tech collective and one in active incubation at HHL.

Market & problem selection

Deciding which customers and markets deserve the company's attention before a line of code is written.

Discovery under ambiguity

Getting to the real problem in markets where users disagree with each other — 100+ construction site visits taught this the hard way.

Shipping reliability

Turning an unpredictable delivery process into one a business can plan around.

Retention as a business problem

Owning churn end to end rather than treating it as a feature backlog.

Work

Case studies

Four problems, each harder than the last. Every study follows the same arc: the problem, what research changed, what I built, what it moved, and what I'd do differently.

Making delivery predictable

Product Owner

The team shipped, but nobody could say when. I rebuilt how work entered and left the pipeline so the business could plan around it.

Getting customers to value faster

Product Manager

New customers took too long to reach the moment the product earned its keep. Discovery work reshaped onboarding around that moment rather than around our feature set.

Owning retention end to end

Product Manager

Churn was treated as a backlog of requests. I reframed it as a business problem with a measurable target and worked the whole funnel behind it.
