The company’s name wasn’t revealed, but Sandy Springs officials think it’s worth holding onto: The City Council on Tuesday approved $294,855 in incentives to keep the firm, code-named “Project Stone,” and its more-than 400 jobs from leaving the city.

The company is expected to decide whether to stay or leave within 30 days, Economic Development Director Andrea Hall told the Council.

The firm sought a waiver of building permit fees and a three-year waiver of business occupational taxes. In exchange, it promised to add more than 125 net new jobs over the next three years, commit to a 10-year lease and invest more than $15 million renovating and expanding its offices.

The new hires and improvements qualify the company for economic development incentives, Hall said.

Each of the 125 new positions “generally reflect high-paying jobs with anticipated total compensation exceeding $100,000 per person,” Savills Studley, a commercial real estate adviser representing the company, said in a letter to the city.
