Santtu Seppälä is a Finnish-American finance professional best known as the husband of actress Sarah Rafferty, who became internationally famous for portraying Donna Paulsen in the legal drama Suits. Although his wife has spent decades working in television and entertainment, Santtu has developed a successful career in investment management, financial analysis, and business development. Their marriage has attracted increasing attention as audiences continue discovering Suits and Rafferty’s more recent television projects.
The couple met while studying at Yale University and married on June 23, 2001. They have two daughters, Oona Gray and Iris Friday, and have maintained a relatively private family life despite Rafferty’s international recognition. Their relationship combines two different professional worlds, with Santtu working in finance while Sarah pursues acting.
Beyond his marriage, Santtu has an extensive professional background that includes positions at Salomon Brothers, Lazard Asset Management, Cantillon Capital Management, Kiitos Capital Management, and Angeleno Group. His career demonstrates that he is an established financial professional rather than simply a celebrity spouse.
Who Is Santtu Seppälä?
Santtu Seppälä is an investment professional whose full name is Aleksanteri Olli-Pekka Seppälä. He has Finnish and American connections and has worked in the United States for much of his professional life.
He became widely recognized through his marriage to Sarah Rafferty, but his career began before the actress achieved international fame through Suits.
His professional experience includes investment banking, equity research, portfolio management, and business development. These roles require evaluating financial information, understanding business performance, and making strategic decisions.
Unlike his wife, Santtu rarely participates in entertainment interviews. Most reliable information about him comes from professional biographies and occasional family-related coverage.
Santtu Seppälä’s Early Life and Background
Santtu has Finnish family roots and maintains connections with Finland. Public biographical records identify his parents as Mr. and Mrs. Antti V. Seppälä, who were associated with Lake Forest, Illinois, at the time of his marriage.
Although several websites publish specific birth dates and estimates of his age, authoritative sources do not consistently confirm those details. His exact age in October 2026 should therefore be treated as unverified.
His educational and professional history is considerably better documented than his childhood.
Santtu eventually attended Yale University, where he developed the academic foundation for his future career in investment management. His connection with Yale also became personally important because it was where he met Sarah Rafferty.
Santtu Seppälä’s Education
Santtu attended Yale College and earned a bachelor’s degree in Ethics, Politics, and Economics. The interdisciplinary program provided exposure to subjects relevant to financial markets, business decisions, and public policy.
He subsequently attended the Wharton School at the University of Pennsylvania, earning a Master of Business Administration.
Wharton is widely recognized for graduate business education, particularly in finance, management, and corporate strategy.
His academic background helped prepare him for employment at established financial institutions.
Rather than moving into entertainment after marrying Rafferty, Santtu continued building a career based on investment research and financial management.
Santtu Seppälä’s Career in Finance
Santtu began his professional career in investment banking, including work at Salomon Brothers and Morgan Stanley.
He later joined Lazard Asset Management, where he spent approximately five years analyzing healthcare companies and investment opportunities.
His responsibilities involved researching businesses, evaluating financial performance, and identifying potential investments across international markets.
Santtu subsequently worked at Cantillon Capital Management in New York. There, he served as an analyst and portfolio manager, including responsibility for the Cantillon Health Fund.
These positions gave him extensive experience managing investments and evaluating market opportunities.
His career eventually progressed toward establishing his own investment management business.
Kiitos Capital Management
In 2008, Santtu founded Kiitos Capital Management, where he served as chief investment officer and managing member.
The firm focused on investment research and portfolio management.
As chief investment officer, Santtu was responsible for directing investment strategies and evaluating opportunities within the firm’s investment framework.
A January 2016 white paper published by Kiitos identified him as the firm’s founder and described his previous experience at Cantillon Capital Management and Lazard Asset Management.
The document provides direct evidence of his professional responsibilities and establishes that he had developed considerable investment experience by that time.
However, the company’s financial performance, assets under management, and Santtu’s personal earnings have not been fully disclosed in recent public information.
Santtu Seppälä’s Role at Angeleno Group
Santtu moved into a business development position with Angeleno Group in 2021.
The Los Angeles-based investment firm focuses on opportunities connected with energy, climate technology, and related industries.
According to People, he became vice president of strategy and business development after spending approximately two decades in investment management.
The transition represented a shift from traditional portfolio management toward broader business and investment strategy.
His experience evaluating companies and financial markets provided a foundation for this work.
As of October 2026, his current professional position should be checked against updated company information rather than assuming that every historical title remains unchanged.
Nevertheless, his association with Angeleno Group remains an important documented stage of his career.
How Did Santtu Seppälä Meet Sarah Rafferty?
Santtu met Sarah Rafferty while they were studying at Yale University.
Rafferty attended the Yale School of Drama, where she completed her graduate acting education.
Their relationship developed during a period when both were preparing for demanding professional careers.
Santtu pursued opportunities in finance, while Sarah continued training and auditioning as an actress.
Their early relationship therefore began long before Suits became a major television success.
Although they later entered very different industries, their shared educational background became an important part of their personal history.
The couple dated for several years before marrying in 2001.
Santtu Seppälä and Sarah Rafferty’s Wedding
Santtu and Sarah married on June 23, 2001, at St. Mary’s Roman Catholic Church in Greenwich, Connecticut.
Their wedding took place approximately ten years before Suits premiered in 2011.
Consequently, their marriage developed before Rafferty became internationally recognizable as Donna Paulsen.
In June 2021, Sarah celebrated their twentieth wedding anniversary with a social media tribute.
She has occasionally shared photographs from their travels and family life, although the couple generally keeps their relationship private.
As of October 2026, they have been married for more than 25 years.
Recent entertainment coverage continues identifying Santtu as Rafferty’s husband.
Who Is Sarah Rafferty?
Sarah Rafferty is an American actress born on December 6, 1972, in Connecticut.
She studied at Hamilton College before completing graduate training at the Yale School of Drama.
Her acting career includes television appearances, film roles, and stage performances.
However, she became particularly famous through Suits, which aired from 2011 to 2019.
Rafferty portrayed Donna Paulsen, a highly capable legal secretary who later became chief operating officer at the fictional law firm.
Her character’s relationship with Harvey Specter, played by Gabriel Macht, became an important part of the series.
Following Suits, Rafferty appeared in Chicago Med and Netflix’s My Life with the Walter Boys, portraying Katherine Walter.
Although fans sometimes associate her strongly with romantic storylines from Suits, her real-life husband is Santtu Seppälä.
Santtu Seppälä’s Children
Santtu and Sarah have two daughters, Oona Gray Seppälä and Iris Friday Seppälä.
Oona was born on October 22, 2007, while Iris was born on January 27, 2012.
Their parents have occasionally discussed family life in interviews, particularly the challenges of balancing professional responsibilities with raising children.
During the production of Suits, Sarah worked in Toronto while the family maintained connections with Los Angeles.
This sometimes required travel and adjustments to the children’s routines.
Rafferty has explained that she and Santtu worked together to manage their responsibilities.
However, their daughters’ everyday activities and private experiences have not been extensively documented.
Santtu Seppälä’s Public Appearances
Although Santtu generally works outside entertainment, he has accompanied Sarah to selected industry events.
In 2017, they attended a Moncler dinner in Toronto and an Alzheimer’s Association fundraising event in California.
In May 2018, the couple attended the wedding of Prince Harry and Meghan Markle at Windsor Castle.
Rafferty’s connection with Meghan developed through their work on Suits, where Meghan portrayed Rachel Zane.
The royal wedding became one of Santtu’s most widely photographed public appearances.
These appearances demonstrate his involvement in important occasions connected with his wife’s professional and personal relationships.
However, attending celebrity events does not mean he works professionally in acting or television.
Santtu Seppälä’s Net Worth
Santtu Seppälä’s exact net worth has not been independently verified.
Some celebrity websites publish estimates of several million dollars, but they generally do not provide reliable financial statements or detailed evidence supporting those figures.
His career in investment management suggests substantial professional experience, but job titles alone cannot establish personal wealth.
An accurate net worth calculation would require information about salary, investments, business ownership, property, and financial obligations.
Sarah Rafferty’s earnings should also not automatically be treated as Santtu’s individual assets.
His financial position therefore remains private.
Where Is Santtu Seppälä Now in 2026?
As of October 2026, Santtu remains publicly known through his career in finance and his longstanding marriage to Sarah Rafferty.
His most recently documented professional background includes his work at Angeleno Group following years in investment management.
The couple continue to be identified as married in recent entertainment coverage, including profiles discussing the cast of My Life with the Walter Boys.
Although Santtu occasionally appears in photographs with Sarah, he has not developed a regular entertainment or social media career.
His current personal income and detailed professional responsibilities remain outside extensive public reporting.
