JAMES SINEGAL

Sinegal grew up in Pittsburgh and landed his first retail job bagging groceries at FedMart in San Diego in 1955, at 18 or 19. FedMart's founder was Sol Price, the man who later invented the membership warehouse, and Sinegal absorbed everything.

He rose to executive vice president of merchandising and operations at FedMart. After Price lost control of FedMart, Sinegal spent a year at Builders Emporium, then a year as executive vice president at Price's new Price Company, the business behind Price Club.

From 1979 to 1983 he ran Sinegal/Chamberlin and Associates, a broker and sales rep firm. In 1983, Sinegal and partner Jeff Brotman opened the first Costco warehouse in Seattle, Washington.

They merged with Price Club in 1993 to form PriceCostco, later renamed Costco Wholesale. Sinegal was CEO from 1983 until he stepped down on 1 January 2012, growing the company from a single warehouse to about 600 locations doing roughly $99 billion a year in sales.

He stayed on the board until 2018.

Costco Wholesale is the company Sinegal built his legacy on. He co-founded it in Seattle in 1983 with Jeff Brotman, after years at FedMart under Sol Price, a short stint at Price Company and four years running his own retail brokerage.

The Kirkland Signature private-label line, launched on his watch in 1995, brought in about $90 billion in sales in 2025, which makes it bigger than Nike. He stepped down as CEO at the start of 2012 and left Costco's board in January 2018.

Sinegal is a builder, not a trader. He compounded value by building customer loyalty and employee loyalty simultaneously rather than by extracting margin.

His core investment insight was that undercutting everyone on price while overpaying workers would create a loyalty flywheel that compounders couldn't touch. He was more interested in reinvesting for long-term shelf space than satisfying short-term investors — and was publicly willing to say so.

Kirkland Signature. Creating a private-label brand that members would trust as much as any national brand was the defining retail innovation of his career.

Launched in 1995, it brought in about $90 billion in sales in 2025, more than Nike's entire revenue. It's a trust machine.

Every time a Kirkland product outperforms a name brand for less money, members get one more reason to renew.

Costco was slow to take online retail seriously. Its e-commerce business stayed a small slice of sales for years while Amazon was building its juggernaut.

Sinegal's whole model was built on getting people into the warehouse, where the treasure-hunt aisles and the $1.50 hot dog did the selling. That model still works, but it left a generation of online bulk buyers to Amazon.

Markup caps are a philosophy, not just a price decision. Sinegal famously enforced a 14% maximum markup at Costco, even on Kirkland products, when competitors were taking 30-50%.

He believed that extracting short-term margin destroyed long-term trust, and that trust was Costco's actual product. He told Wall Street this directly and often.

It was a genuinely unusual thing for a public company CEO to say out loud.

Married to Janet Sinegal for decades. They have three children.

Their son David runs Sinegal Estate, a winery in St. Helena, California.

Sinegal is a Democrat who spoke at the 2012 Democratic National Convention and hosted President Barack Obama at his home twice. He keeps the rest of his family life largely out of the business press.

Earned an associate degree from San Diego City College in 1955 and a bachelor's degree from San Diego State University in 1959. His real education, though, was the warehouse floor.

He started bagging groceries at FedMart in 1955, while he was still a student. Dartmouth gave him an honorary doctorate in 2017.
