Smile Direct Club plans to hire 2,010 new employees through 2024, the fast-growing Nashville-based startup announced Wednesday.

The growth would more than double the five-year-old company's presence in Music City, and represents an increase of more than 45 percent in its nationwide workforce.

The planned $217 million investment also comes as the company — valued at $3.2 billion last year — reportedly is considering making an initial public offering this summer.

The new jobs will be divided between its downtown offices and expanded facilities in Antioch, officials said in a joint press conference with Gov. Bill Lee on Wednesday morning at the company’s downtown Nashville headquarters.

“It is really a great day for Tennessee,” Gov. Bill Lee said. "One of the things that changes people’s lives is having a good job and one of the ways jobs are created is companies making a decision to commit to our community.”

The company pulled in $400 million in revenue last year and anticipates more than doubling that to $1 billion this year.

Its Nashville growth will come with a new "significant incentive" from the state, officials said. But the package, which could involve cash payments and tax breaks, has not yet been finalized, said Department of Economic and Community Development Commissioner Bob Rolfe.

"We're still negotiating the final incentive," Rolfe said. "It's a healthcare company, it's a beauty company, a tech company, a manufacturing company. These jobs are such high quality, family wage jobs."

This would be the second incentive from the state in two years. In February 2017, state officials provided $330,000 to the company, with the promise that they would invest at least $4.5 million and create 439 jobs. Performance reports for that grant were not immediately available Wednesday, but state officials said the company exceeded those targets.

Smile Direct Club specializes in low-cost at-home teeth straightening products. It has more than 200 shops around the country where customers can be fitted for clear teeth aligners and retainers. Customers can also use at-home impression kits to order the products.

Its headquarters moved from Detroit to Nashville in 2016.

"Smile Direct Club is a disruptor in the orthodontics space," said Cheryl DeSantis, the company's chief people officer. "We provide our customers with an affordable and convenient way to straighten their smiles through invisible aligner therapy. Our mission has always been to increase access to affordable care."

More than 500,000 customers have ordered the tech-enhanced braces.

But the American Association of Orthodontists has filed complaints against the company and similar direct-to-consumer medical businesses. The trade association recommends thorough teeth and jaw X-rays, and in-person medical consultations, before and while undergoing treatment. Smile Direct Club officials said it partners with hundreds of licensed dentists and orthodontists.

Smile Direct Club's Nashville headquarters occupy floors 7 to 10 of Philips Plaza, a 20-story building at 414 Union St.

Healthcare and technology company Philips has the largest presence in the building. It similarly leverages new and emerging technologies to deliver lower-cost healthcare products to market.

Smile Direct Club also has offices at 601 Bakertown Road in the southeast Nashville community of Antioch. Those include manufacturing, distribution, and research and development offices.

The company will concentrate most of its growth in the next five years in Antioch, where it expects to hire about 1,340 new employees. It will also expand its downtown offices with about 670 additional hires.

"We're very pleased and very proud that this company has decided to make a major expansion. They had a decision of many places to go for this expansion and they decided to to it here," Lee said. "Companies like this one are the ones that change our state, and take it from where it is today and make it a leader in the country."
