Senior Product Manager · Payments & Fintech

I build products where money moves and trust has to be earned.

Seven years owning payments end-to-end — integrations, checkout, billing, market expansion. I work at the intersection of financial systems and user behaviour: where a bad decision costs real money, and a good one compounds.

Billing · Monetisation

The billing system that scaled 60×

Built lean to validate, broke under load, rebuilt right. The infrastructure behind $12M of annual revenue — and two scars that shaped how it got there.

Payments · Strategy

The validation bet that stopped a bad PSP build

Leadership overruled a hard no. I found a third option: a 2-week PayPal test instead of a 6-month integration. The evidence it produced reshaped our market strategy.

2 weeks vs. a multi-month full PSP build
Market Expansion · Delivery

Two new markets. Half the integration time.

Compressed a 9-month PSP integration to 3–4 months by resequencing the build. Held the delivery together as the team reformed around me mid-project.

Craft · Experimentation

The first A/B test, done right

FareHarbor's first experiment. Pre-registered MDE, held the run length when the early signal was tempting. Now a practice running at 25+ experiments a year across the org.

Vision · Strategy

A vision that outlived my ownership of it

Authored a reporting vision, let go of the surface, watched the thesis become a pillar of company strategy — delivered by a team I no longer ran.

Discovery · Reframe

The wrong solution, caught before we built it

CS asked for bulk cancellation tools. The data said individual bookers controlled their own decisions. I reframed the problem — and dispute rates dropped 60%.

How I work

Principles that show up consistently across the stories — in how I frame problems, make bets, and decide when to let go.

I go to the source before committing to a solution

The first framing of a problem is usually someone's assumption. I query the data, talk to the operators, and let the evidence reshape the question before building anything.

Measurement is a design decision, not an afterthought

Pre-registered experiments. Dispute backtests timed to window closure. Dashboards built because the instrument didn't exist yet. Rigour is how I earn the numbers I cite.

When something is blocked, I look for the third option

A hard no from leadership isn't always the end. A validation bet, a segmented experiment, a redirected framing — constraints often produce sharper solutions than open mandates.

I surface structural problems honestly, even when it costs me

Twice I told my manager I couldn't do justice to two surfaces simultaneously. Both times a new team was created. I'd rather lose scope than quietly underdeliver on both.

A bit about me

Adithya Venkat

I came into product through engineering and finance — a risk manager at Optiver before I realised what I actually liked was finding hard problems in transactional systems and building things that solved them. I didn't yet know that work was called product management.

I've been at FareHarbor since 2019, where I've owned Payments end-to-end across two product teams. I'm based in Amsterdam.
