Santtu Seppälä’s Age and Birthday
Santtu’s exact date of birth is not reliably confirmed.
Some online biographies list December 6, 1974, but this information conflicts with a birthday post from Sarah Rafferty. In 2020, Sarah reportedly celebrated Santtu’s 50th birthday, which would suggest he was born around 1970.
December 6 is also Sarah Rafferty’s birthday, making the online claim about Santtu’s birth date more questionable.
For this reason, his exact age and birthday should not be presented as confirmed facts.
Where Is Santtu Seppälä From?
Santtu Seppälä was reportedly born and raised in Finland.
His exact city of birth has not been publicly established in the available information.
Some online sources claim he was born in the United States, but stronger biographical information describes him as Finnish-born.
He is reported to hold dual citizenship in Finland and the United States.
He Grew Up in Several Countries
Santtu Seppälä had an international upbringing.
He has reportedly lived in:
- Finland
- Sweden
- Denmark
- France
- Germany
- United States
He eventually attended university in the United States and later built much of his professional career there.
Santtu Seppälä’s Parents and Siblings
Very little reliable information is publicly available about Santtu’s parents.
Their names and professions have not been confirmed in the supplied information.
It is also not publicly clear whether he has any brothers or sisters.
He Studied at Yale University
Santtu Seppälä attended Yale University.
He reportedly graduated in 1993.
Some sources describe his Yale qualification as a degree in finance, while another describes it simply as a Bachelor of Arts. Because the available reports differ, his exact undergraduate major should be treated carefully.
Yale was also important to Santtu’s personal life because it was where he met Sarah Rafferty.
Santtu Played Tennis at Yale
Santtu was involved in college sports while studying at Yale.
He was a member of the Yale varsity tennis team and has been described as an Ivy Champion.
His time as a college athlete is one of the few publicly reported details about his life before entering finance.
He Earned an MBA From The Wharton School
After Yale, Santtu Seppälä continued his education at The Wharton School of the University of Pennsylvania.
He reportedly entered Wharton in 1994 and earned his MBA in 1998.
His business education was followed by a long career involving investment management, portfolio management, strategy, and business development.
Santtu Seppälä’s Career in Finance
Santtu built a professional career outside the entertainment industry.
He has worked in finance and investment management for more than two decades.
His reported career includes positions at Salomon Brothers, Lazard Asset Management, Cantillon Capital Management, Kiitos Capital Management, and Angeleno Group.
He has worked as an analyst, investment professional, portfolio manager, chief investment officer, and business development executive.
His Early Career at Salomon Brothers
Santtu Seppälä reportedly began his professional career at Salomon Brothers around 1993.
Sources describe his early role as either a financial analyst or investment banker.
Salomon Brothers was one of the early steps in his long career in finance.
Reported Time With the Finnish Defence Force
One source reports that Santtu spent about a year with the Finnish Defence Force during the 1990s.
This detail is not included in all available profiles, so it is best treated as reported rather than fully confirmed.
He Worked at Lazard Asset Management
Santtu Seppälä reportedly worked as an analyst at Lazard Asset Management.
One source says he spent around five years there.
He later moved into more senior positions in investment management.
His Work at Cantillon Capital Management
Santtu Seppälä also worked at Cantillon Capital Management in New York.
He served as a portfolio manager, according to the available information.
This position formed part of the roughly two decades he spent working in investment management.
He Founded Kiitos Capital Management
Santtu Seppälä later became the founder of Kiitos Capital Management.
He also served as the firm’s Chief Investment Officer.
This was a senior role involving investment management and decision-making.
Santtu Seppälä and Angeleno Group
Santtu Seppälä joined Angeleno Group in 2021, according to the available biographical information.
He was identified as the company’s Vice President of Strategy and Business Development.
Angeleno Group is a Los Angeles-based investment firm.
Because business positions can change, the supplied information does not establish with certainty that this remains his exact job title in 2026.
His Reported Role at Staxxon
Another source also connects Santtu with Staxxon.
It reports that he served as Chief Strategy Officer and a member of the company’s management committee.
This position is less clearly documented in the supplied information than his work with Angeleno Group, so it should be treated as a reported role.
How Did Santtu Seppälä Meet Sarah Rafferty?
Santtu and Sarah Rafferty met when they were both students at Yale University.
They dated for several years before getting married.
Sarah shared an old photograph in 2020 that reportedly showed the couple together in 1994. She described it as their first photograph together as a couple.
This means their relationship dates back to at least the mid-1990s.
Santtu Seppälä and Sarah Rafferty Married in 2001
Santtu and Sarah married on June 23, 2001.
Their wedding reportedly took place at the Roman Catholic Church of St. Mary in Greenwich.
The ceremony was reportedly officiated by Rev. Alfred Riendeau.
Sarah celebrated their 20th wedding anniversary in 2021 by sharing a photograph from their wedding.
In June 2026, they reached 25 years of marriage.
Who Is Sarah Rafferty?
Sarah Rafferty is an American actress best known for playing Donna Paulsen in the legal drama Suits.
She appeared on the show from 2011 to 2019 alongside actors including Gabriel Macht, Patrick J. Adams, and Meghan Markle.
Sarah has also appeared in projects including Chicago Med, My Life with the Walter Boys, Speakeasy, All Things Valentine, and Small, Beautifully Moving Parts.
Her career is very different from Santtu’s work in finance and investment management.
Santtu and Sarah Have Two Daughters
Santtu and Sarah have two daughters, Oona Gray Seppälä and Iris Friday Seppälä.
Oona was born in 2007. One supplied source gives her birthday as October 22, 2007.
Iris was born in 2012, with one source placing her birth in January.
Sarah occasionally shares family moments on Instagram, but the couple generally keeps detailed information about their daughters private.
Their Family Life During Suits
Sarah’s work on Suits required her to spend significant time in Toronto, Canada, where the show was filmed.
The family’s main home base was in Los Angeles.
Instead of living separately for long periods, Santtu, Sarah, and their children moved between Los Angeles and Toronto as a family.
Sarah said in a 2013 interview that one of their daughters attended two schools because of the arrangement. Although Sarah initially worried about it, she later described it as a positive experience for her daughter.
Sarah Has Called Santtu an Important Partner
Sarah has publicly credited Santtu with helping their family manage two demanding careers.
She described him as an “amazing spouse” and said they worked as a team so both could work while remaining present for their children.
Sarah said she did not believe their lives had a perfect work-life balance. Instead, they learned how to handle changing responsibilities together.
Santtu and Sarah Enjoy Traveling
Travel has been part of Santtu and Sarah’s relationship for many years.
Sarah has shared photographs from several trips they took together.
One picture came from a trip to Istanbul in 2004. Another was from Bhutan in 2005.
In a birthday post, Sarah described traveling around the world with Santtu as one of her favorite activities.
They Spend Time Together Away From Work
Sarah has also discussed some of the activities she enjoys with Santtu.
She has said they enjoy hot yoga, hiking, and going out to dinner together.
She described having dinner without interruptions as a chance for them to talk away from their work and parenting responsibilities.
Sarah has also said that an ideal family Sunday can include Finnish pancakes made by Santtu.
They Attended Prince Harry and Meghan Markle’s Wedding
Santtu accompanied Sarah to the wedding of Prince Harry and Meghan Markle on May 19, 2018.
The wedding took place at St George’s Chapel at Windsor Castle in England.
Sarah knew Meghan through Suits, where Meghan played Rachel Zane.
Santtu and Sarah were photographed arriving together for the royal wedding.
Santtu Seppälä’s Other Public Appearances
Santtu occasionally attends public events with his wife.
On October 25, 2017, he and Sarah attended a Moncler dinner in Toronto celebrating the opening of a boutique.
He has also appeared with Sarah at other selected events.
However, Santtu generally maintains a much lower public profile than his actress wife.
Does Santtu Seppälä Have Social Media?
Santtu does not have a clearly confirmed public social media account in the available information.
Sarah Rafferty is active on social media and sometimes shares photographs of her husband.
As a result, many public photographs and personal details about Santtu come from Sarah’s accounts rather than his own.
Santtu Seppälä’s Net Worth
Santtu’s personal net worth is not reliably known.
Some online sources estimate his wealth at around $10 million, but there is no authoritative financial information confirming that figure.
The $10 million amount should therefore be treated only as an unverified online estimate.
