Jewel Commerce LLC, a Detroit-based startup that offers rebates to online customers of luxury retailers, has been acquired by Capital One Financial Corp. just two years after launching.

More expansion is in store for the company following the purchase, which closed earlier this month, said Andrew Landau, co-founder of Jewel Commerce. Its five employees will remain, and more are expected to be hired. Landau remains CEO of the company and co-founder Dushan Shimko keeps the role of chief technology officer.

Terms of the transaction were not disclosed.

"Capital One is developing a set of tools that help customers simplify their lives and make smart financial decisions," Landau said. "This (acquisition) is part of a way to add to that."

Landau said he could not pass up the opportunity to become part of a company that has the resources and capital to help it scale.

"Whether they are shopping luxury retailers or everyday brands, consumers want to be able to shop with confidence that they are getting great value," Walt Roloson, vice president at Capital One Financial, said in an emailed statement. "Capital One and Jewel have a shared goal of providing simple, straightforward digital tools that can help consumers effortlessly save time and money."

On Jewel's website, usejewel.com, users can browse goods from luxury and high-end clothing, accessory, home goods and shoe retailers. Purchasing through the website earns users cash rebates of anywhere from 2 percent at Arhaus to 35 percent at Stitch Fix and 60 percent at Scentbird.

Landau said the company has deals with "hundreds of retailers" and has issued "hundreds of thousands of dollars" in rebates to customers.

Jewel is the second company Landau has helped build from scratch and sell. He founded Chalkfly LLC, a Detroit-based online provider of office and janitorial supplies, in 2012 with his brother before it was sold in 2014. After that, he moved to New York to take a job as head of business development for e-commerce company jet.com. He moved back to Detroit in 2017 and founded Jewel.

The company initially raised $175,000 in seed funding from three local angel investors, Crain's reported last June. Since then, it has raised a total of $500,000 in capital from those same investors. It has grown from two to five full-time employees, and revenue growth has been "exponential," Landau said. He declined to disclose figures.

Jewel, which is headquartered at Grand Circus downtown, will remain in Detroit — a stipulation for Landau.

"It's a smart entrepreneurial decision to start a business in Detroit because of the people and the culture and attitude of the overall community," he said.

Details for hiring more employees have not been solidified.

"I think we're really just at 'chapter one' of where the business is going to go," he said.
