Julian Croonenberghs Built a Rare Path From Hockey to Finance

Introduction

Julian Croonenberghs works in private equity at Hg in New York. Before finance, though, his story looked very different.

He played international field hockey.

He studied mathematics and computer science.

Then finance took over.

Hg currently lists Croonenberghs as a member of its Mercury team. The firm says he joined in 2024 after working for Goldman Sachs in New York.

That mix of sport, technology, mathematics, and finance has made people curious about him, especially after his name entered wider entertainment coverage in 2026.

Who Is Julian Croonenberghs?

Julian Croonenberghs is a New York-based finance professional who currently works with Hg’s Mercury team.

His path there was not standard.

Before private equity, he worked in investment banking at Goldman Sachs. Before Goldman, he studied Applied Mathematics and Computer Science at Brown University. Before that career even started, competitive field hockey was already a major part of his life.

He reached senior international level.

That is the interesting part.

USA Field Hockey’s 2019 annual report records Croonenberghs earning his first senior international cap for the United States during matches against Ireland in May 2019.

Early Life in Belgium

Croonenberghs spent much of his early life in Belgium.

A 2019 interview with Belgian hockey publication Okey gives one of the clearest public accounts of his family background. It described him as the son of a Belgian father and American mother. His father, Olivier, came from the Antwerp region.

Hockey arrived very early.

Croonenberghs played at Orée, a Belgian hockey club, and his childhood became closely tied to the sport.

The same interview shows something else.

His connection with the United States was already part of his family story. That later gave him a route into American international hockey after moving to the U.S. for university.

Public records connect him with Tervuren, Belgium, during his hockey years. USA junior-team material also listed him with Tervuren.

His Hockey Years

Hockey came before banking.

Way before.

Croonenberghs played in Belgium while growing up and later entered the United States national-team setup.

His route into American hockey happened almost by chance.

In his 2019 Okey interview, Croonenberghs explained that he did not expect to continue serious field hockey after arriving at Brown University. During his first days there, a chance connection with coach Rutger Wiese helped put him back into competitive hockey.

Things moved quickly after that.

In 2019, he entered the senior United States setup.

USA Field Hockey’s annual report says the May series against Ireland produced the first international caps for Julian Croonenberghs and Alberto Montilla.

Croonenberghs then appeared at the 2019 FIH Series Finals in Bhubaneswar, India.

Global Sports Archive records five appearances in that competition and one field goal. The United States played South Africa, Mexico, Japan, South Africa again, and Japan during his five recorded tournament appearances.

He was still involved with the American system later that year.

An October 2019 U.S. U-21 Men’s National Training Squad included Croonenberghs and listed his location as Tervuren, Belgium.

So yes, the hockey record is real.

He did not simply play recreationally.

He reached international level.

Brown University Education

Croonenberghs attended Brown University.

Hg states that he received a B.S. in Applied Mathematics & Computer Science from Brown.

It is a technically demanding academic combination.

Brown describes its Applied Mathematics–Computer Science Sc.B. program as combining mathematical analysis, computation, computer science, and related quantitative work.

That academic background makes his later finance career easier to understand.

Math mattered.

So did computing.

And his university work was not limited to textbooks.

Interest in Programming and Machine Learning

Croonenberghs also has a public software portfolio.

His Devpost profile lists programming skills including Python, Java, C, JavaScript, and TypeScript. It also lists interests in cybersecurity, fintech, and machine learning/AI.

One project stands out.

In 2020, Croonenberghs worked with James Pirozzolo and William Kantaros on “What’s the vibe? Twitter Sentiment Analysis.”

The project was submitted to Brown Deep Learning Day 2020.

Their idea was simple to explain.

They used deep learning to analyse whether Twitter posts carried positive or negative sentiment. The team built the work in Python and tested its model on large sets of tweets.

Basically, his technical background was real before his move into full-time finance.

That matters.

It shows a broader academic profile than the usual celebrity coverage suggests.

From Brown to Goldman Sachs

After university, Croonenberghs entered investment banking.

Goldman Sachs became the big name on his early finance résumé.

FINRA records show that Julian L. Croonenberghs was registered with Goldman Sachs & Co. LLC in New York from August 2022 until August 2024.

Hg gives more detail.

According to his official company profile, he worked on Goldman Sachs’ Financial Institutions Investment Banking team in New York.

That placed him inside a finance group dealing with companies in financial services.

His FINRA record also shows two general industry/product examinations on his regulatory record and no disclosure events in the current BrokerCheck report.

The wording matters here.

That means FINRA’s report currently lists no disclosure events. It should not be stretched into claims about areas outside FINRA’s reporting scope.

Joining Hg

Croonenberghs left Goldman Sachs and joined Hg in 2024.

Hg is where he works now.

His official company page identifies him as a member of the Mercury team in New York.

This marked his move from investment banking into private equity.

The career line is pretty clear:

Brown University → Goldman Sachs → Hg.

But hockey sits beside that path.

So does software.

That combination makes his background less typical than it first appears.

What Does Julian Croonenberghs Do at Hg?

Hg publicly identifies him as part of its Mercury team.

The company does not publish a detailed day-to-day breakdown of his individual responsibilities on his profile. So claims about specific deals, personal investment decisions, compensation, or portfolio ownership should not be added without stronger evidence.

What we can say is simple.

He works with the Mercury team.

He is based in New York.

And he joined after working in Goldman Sachs’ Financial Institutions Investment Banking team.

Julian Croonenberghs and Olivia Rodrigo

Croonenberghs became far more widely searched in 2026 after being photographed with singer Olivia Rodrigo.

Entertainment coverage first linked the pair after they were seen together in Brooklyn in June 2026.

They were later photographed together again, including during a Brooklyn park outing. People described Croonenberghs as Rodrigo’s new boyfriend in its coverage.

There is one detail to keep clear.

Neither Rodrigo nor Croonenberghs had given a direct public statement confirming their relationship in the reliable coverage checked for this article.

Elle reported the sightings while also noting that the pair had not publicly confirmed the relationship themselves.

So the safest description is that they have been publicly linked and photographed together.

His Family’s Link With Music

Croonenberghs’ sister, Jade Croonenberghs, has also appeared in 2026 coverage.

People reports that Jade works in the music business and has been involved with Les Filles while also working as a DJ.

This led to guesses that she may have connected her brother with Olivia Rodrigo.

But that story is not confirmed.

Elle noted the possible connection while making clear that the exact way Julian and Rodrigo met remains unclear.

So it should stay a theory.

Not a fact.

Does Julian Croonenberghs Have a Public Net Worth?

No reliable public figure is available.

Various entertainment and profile websites may attach dollar amounts to his name, but there is no strong financial source supporting a personal net-worth estimate.

His employers are public.

His assets are not.

So publishing a specific figure would mean guessing.

The same issue applies to his current salary at Hg.

No verified personal salary has been publicly disclosed in the sources checked for this article.

What About His Exact Age and Birthday?

A precise date of birth appears on some secondary profile websites.

It is not confirmed by the strongest sources checked here.

The 2019 Okey interview described Croonenberghs as 18 at that time, but it did not provide a full verified date of birth.

Because of that, an exact birthday should not be presented as settled fact without a better source.

Is Julian Croonenberghs Married?

Reliable public reporting does not establish a marriage.

There is also no strong public record in the sources checked here showing that he has children.

His private life attracted little media attention before 2026.

That changed once he began appearing in entertainment coverage with Olivia Rodrigo.

Why Is Julian Croonenberghs Getting Attention?

The easy answer is Olivia Rodrigo.

But that is only part of it.

His own record is unusual.

He grew up around Belgian hockey, played internationally for the United States, studied applied mathematics and computer science at Brown, worked with machine-learning projects, entered investment banking at Goldman Sachs, and later moved to Hg.

Those are documented steps.

No hype needed.

Final Thought

Julian Croonenberghs had already built an interesting career before entertainment media started following him.

Sport came first.

Then Brown.

Then Wall Street.

Now he works in private equity with Hg’s Mercury team in New York.

His U.S. field-hockey record is documented, his Brown education is confirmed, and his Goldman-to-Hg career path is public.

The private parts should stay private.

Exact wealth claims, unsupported personal details, and guesses about his relationships or family should not be treated as facts.
