The family then moved to purchase Banco de Colombia for $365 million, in what was then the largest privatization in Colombia's history. A group of premier private equity investors led by Morgan Stanley Asset Management investing $65 million, billionaire George Soros investing $50 million and Tiger Asset Management with $35 million together with more than 100 other European and North American institutional investors co-invested with Gilinski. Later, the family sold control of the bank to Banco Industrial Colombiano, and its controlling stakeholder Sindicato Antioqueño, in a deal valued at $800 million, among Colombia's largest deals. Gilinski received $418 million for its stake and retained a minority position in the new bank as part of the deal. As of 2018, Bancolombia was the largest in Colombia with a market capitalization of $11 billion on the NYSE.

In September 2013, Banco Sabadell announced that Gilinski became its largest shareholder as the anchor investor in a US $1.8 billion capital raise. Through the ABB and share rights issue, Gilinski's investment totals approximately $500 million. Banco Sabadell is the 5th largest bank in Spain, with over US $220 billion in assets and a 13% market share.

In May 2012, HSBC announced the sale of its Latin American operations (Colombia, Peru, Paraguay) to Banco GNB Sudameris for $400 million in cash.

In 2003, Gilinski acquired and subsequently merged Banco Sudameris and Banco Tequendama. This merger created GNB Sudameris, a bank with assets of over US $10 billion that ranks among the largest private Colombian banks as of 2018. The purchase of Servibanca, an ATM network with over 2,600 machines, and Suma Valores, a stock exchange commission agent company, has further expanded the network.

In the 1990s, Gilinski acquired the Colombian assets of BCCI (Bank of Credit and Commerce International) for a nominal sum after its global collapse. Renamed Banco Andino, it became one of the most efficient banks in the Colombian banking system within four years. The Gilinski Group sold the reconstituted bank for a reported $70 million.

In the 1990s, the Gilinskis contributed US$8 million to the Fundacion Santa Fe. This was during Jaime Gilinski's time as chairman of Banco de Colombia. La Fundación Santa Fe de Bogotá supports Santa Fe Hospital in Bogotá. Founded in 1972, this hospital is recognized as Colombia’s most technologically advanced.

Gilinski earned his BS in Industrial Engineering from Georgia Tech in 1978, and an MBA from Harvard Business School in 1980.
