A fast-growing tech firm is more than doubling its footprint in a new downtown Dallas redevelopment.

Digital firm OrderMyGear has rented 23,000 square feet of offices in the new East Quarter redevelopment along Commerce Street at Cesar Chavez. The building where the company is expanding at 2211 Commerce Street was a Cadillac auto dealership back in the 1920s and 1930s.

OrderMyGear, which provides digital software services for the apparel and sporting goods industries, has 80 workers at its downtown headquarters. It is one of the largest businesses located in the 8-block area that is being redeveloped on the east side of downtown.

The company recently earned a spot on Inc.'s annual ranking of fastest growing businesses in the nation. With revenues of $13 million in 2017, OrderMyGear posted three-year growth of 676 percent.

Earlier this year, OrderMyGear raised $35 million from investors to add new features to its software and to boost marketing efforts.

"The expanded space will support the potential doubling of our headcount during the next few years," James Skidmore, company co-founder and COO, said in a statement. "Our team is excited to expand and be a part of the growth in the East Quarter."

Developer Todd Interests and J.P. Morgan Asset Management acquired more than a dozen buildings and land in the area earlier this year and have begun renovations of the old commercial properties — most built between the 1920s and 1930s. The old buidings are being converted to new office, restaurant and retail stores.

"The East Quarter district provided a unique opportunity for OrderMyGear to renew and expand in its current space," Cushman & Wakefield senior director Cribb Altman said in a statement. "The chance to be an anchor tenant in a new downtown district, while also staying in a building that's part of the company's history, were major selling points."

Cushman & Wakefield's Altman and Charlie Beck negotiated the new lease with Patrick Todd of Todd Interests.
