In 2020 Spier hosted a panel on "The Future of Intelligent Investing" with Niall Ferguson, Sandy Climan and Daniel Aegerter.

Upon leaving the investment banking Spier founded the Aquamarine Fund, an investment partnership inspired by, and styled after Warren Buffett's 1950s investment partnerships – which he continues to manage today and which had $250 in AUM as of December 31st, 2019

In 2016 Spier, along with Phil Town and Matthew Peterson successfully petitioned Judge Sontchi at the Delaware Court of Bankruptcy to form an official committee of equity holders of Horsehead Corporation – which had filed for bankruptcy earlier that year.

In 2014 Palgrave MacMillan published "The Education of a Value Investor" which narrates Spier's early career struggles in investment banking on Wall Street and his transformation into a Value investor. The book has sold more than 50,000 copies in English and has been translated into Spanish, German, Japanese, Korean, Chinese, Polish and Vietnamese.

Spier lives in Zurich with his wife Lory and three children – Eva, Isaac and Sarah. He is related to the Lazard banking family through his great great grandmother, Johanna Lazard. He is a former resident of Tuxedo Park, New York, the village constructed by Pierre Lorillard in the late 1800s, where he lived in the Bruce Price Cottage. He is a member of Entrepreneurs' Organization and of the Young Presidents' Organization.

Spier has regularly advocated for probity and modesty in the management of financial firms. In 2008 Spier published a paper along with Peter Sinclair and Tom Skinner on "Bonuses, Credit Rating Agencies and the Credit Crunch" which argued that part of the cause of the 2008 crisis was short-termism leading to the miscalculation of bonuses at Credit Rating and other financial firms. He has also strongly advocated in favor of Zero management fees when it comes to professional investment management.

In 2003, Spier became the target, along with David Einhorn, Bill Ackman, and Whitney Tilson, of investigations by Eliot Spitzer, then the New York Attorney General, as well as by the U.S. Securities and Exchange Commission regarding short sales of Farmer Mac, MBIA corp and Allied Capital. The melt down of these companies during the late-2000s financial crisis vindicated their short thesis and was the subject of books by Ackman and Einhorn.

From 2000 to 2005 Spier served, with the close support of Amanda Pullinger as the President of the Oxford Alumni Association of New York. Under his and Pullinger's leadership, the association grew to over 5,000 members and was a pioneer in bringing an American style approach on alumni relations to a British university. From 2007 to 2009, Spier served on the Advisory Board of the Dakshana Foundation.. In 2011, Spier founded the VALUEx conference in Klosters. In 2017 Spier joined the newly formed board of the Swiss Friends of Oxford University. He also serves on the advisory boards of Horasis, and World Minds He is also a member of the International Council of the Global Leadership Foundation which was founded by Nobel Peace Prize winner F. W. de Klerk.

In 1997, Spier spoke out in the Independent against the increasing intrusion of paparazzi in British public life, writing "...if such a regime had been in place before last weekend, every tabloid which published photographs of Princess Diana and Dodi on their summer holidays would have been required to pay the resulting profits to them. I do not think that it would take too fine a legal mind to distinguish between public events, such as speeches and hospital visits, and private events, such as a ski trip with one's children or a ride in a car with a friend." In 2002, writing in the Financial Times Spier questioned the motives of the directors of the Hershey Trust Company for selling out their stake asking, "Why would anybody in their right mind want to trade a significant share of Hershey, with its excellent characteristics, for an insignificant share of a hotchpotch of US business, probably chosen by some adviser who is better at getting selected than at delivering investment performance?"

In 1990 Spier was offered places both in the Joint Business and Economics PhD program and at the MBA Program at Harvard. He opted to do the MBA and in 1993 he completed his MBA. Contemporaries at HBS include Mark Pincus, Chris Hohn and Sherry Coutu.

From 1988 to 1990, Spier was an associate at Braxton Assoiates, the strategy consulting firm which was later sold to Deloitte Consulting. Based out of the London and Paris offices, Spier worked with colleagues David Pitt-Watson, Michael Liebreich and others in advising British and European companies on their strategy vis-a-vis the European Common market. He subsequently took up an internship at the Forward Studies Unit (Cellule de Prospective) at the European Commission in Brussels.
