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.

−25 → +3 Feature NPS, first net-positive in tracked period
Process · First Hire

No PM, no process — and three cofounders still approving every line of code.

FareHarbor's first external PM hire, with no delivery process to inherit. When Amsterdam's need for small pull requests collided with three cofounders who required sign-off on every merge, I found the third option that let both sides keep what mattered.

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.
