Less than a month after announcing it would open a technology hub in a yet-to-be-named Central Indiana city, India-based Infosys has made a quick decision.

Infosys has leased 35,000 square feet at the 36-story OneAmerica Tower in Downtown Indianapolis, where it will open a technology center for up to 2,000 employees. Infosys revealed its decision Tuesday at Lucas Oil Stadium, exactly three weeks after the company said it would begin searching for space across the Indianapolis area.

"Infosys joining Indianapolis in no small measure reveals our city's future," Mayor Joe Hogsett said. "For when Infosys invests in Indianapolis, it also begins investing in our city's youth, bringing STEM (science, technology, engineering and mathematics) and technology training programs to local students and positioning our children to succeed in the global workforce of the 21st century."

Infosys did not make anyone available for an interview. While a handful of company officials attended the announcement, held in the unusual setting of an NFL stadium concourse, top executives were in San Francisco for the company's Infosys Confluence conference.

Infosys Chief Operations Officer Ravi Kumar in a statement touted Indiana's workforce and universities, saying "innovation and education are at the heart of Infosys."

The company's decision adds momentum to Indianapolis' push to become a tech hub — a distinction for which Indianapolis is competing against virtually every other sizable city in America, including its suburbs.

San Francisco-based cloud computing giant Salesforce last week officially opened its 250,000-square-foot space in the newly renamed Salesforce Tower, perhaps the city's greatest tech victory to date. But the city also has a thriving startup culture that includes a wide range of fast-growing companies such as food-delivery service ClusterTruck and email signature marketing company Sigstr.

While Infosys is broadly known for information technology, its work includes cloud computing, artificial intelligence, machine learning and other technology services. The company's plan for Indianapolis marks what could become the state's second-largest job announcement to Honda's decision more than a decade ago to build a $578 million plant in Greensburg and hire 2,064 workers.

In exchange for choosing Indiana, Infosys is in line for the largest incentive package in state history. It could receive up to $31 million in conditional tax credits and training grants.

The city also is offering Infosys a 10-year property tax abatement and $2.5 million training grant if the company hires and retains at least 37 full-time jobs with average wages of at least $45 per hour and 300 jobs paying an average of at least $36 an hour. The company must complete its hiring by the end of 2019.

Infosys has said it could add as many as 2,000 jobs by 2021. The company already has 140 employees in Indiana, including workers based at companies such as Cummins and Eli Lilly.

Infosys plans to hire 100 more workers by the end of 2017 and an additional 400 people next year. The company expects to spend more than $8.7 million to essentially create a U.S. headquarters.

Launching an Indianapolis hub marks a turn for Infosys, which is known for a business model of hiring Indian engineers on H-1B visas and outsourcing their labor to U.S businesses.

Indianapolis officials met with Infosys several months ago when it expressed interest in Central Indiana, Hogsett said.

"We got to know one another," he said.

State officials earlier this month said Infosys was considering six sites in Central Indiana. Infosys' May 2 announcement was a "green flag for all the communities throughout Central Indiana," Hogsett said. The city began making its case "at the end of the press conference," he added.

"Cities like Fishers and Carmel were, I think, very aggressive in their recruitment of Infosys, as were we," Hogsett said.

Raju Chinthala, the president of the Indiana India Business Council, who has worked with Infosys to help acclimate the company to Central Indiana, said Infosys signed its OneAmerica lease last week.

The company's announcement came three days after Salesforce CEO Marc Benioff seemed to inadvertently disclose that Infosys had decided to locate in Indianapolis — though Benioff told the Indianapolis Business Journal that Infosys would lease space in Salesforce Tower, not OneAmerica.

Chinthala said he thinks Infosys will stick with the OneAmerica Tower "for now." Infosys officials did not address Benioff's comment.
