Goldman Sachs Group Inc. is eyeing the region as a possible home for its asset-management arm, according to people familiar with the matter. A spokesman said the company was pursuing a “strategy of locating more jobs in high-value locations throughout the U.S., but we have no specific plans to announce at this time.”

A string of smaller tech and finance firms recently opened offices in the area, or said plans are in the works. Venture capitalists including Keith Rabois and Jon Oringer have moved here and hailed its emerging tech scene.

“The sun, moon and stars have all aligned,” said Nitin Motwani, managing partner of the Miami Worldcenter mixed-use development, who has helped woo firms to the city. “The new normal is going to see a lot more growth happening here.”

Various factors are at play beyond beaches and subtropical weather, he and others say. Florida has no personal income tax and low corporate taxes. The 2017 federal tax law capping deductions for state and local taxes enhanced Florida’s appeal for wealthy residents of high-tax states. And the coronavirus pandemic made clear for many people that they could work remotely from anywhere.

Blackstone settled on Miami for its new office in part because of the growing pool of tech talent, fed by local universities and existing companies, said John Stecher, the firm’s chief technology officer. Other pluses: the city’s nightlife, restaurants and thriving arts scene.

It is “a world-class destination city where people want to live,” Mr. Stecher said.

Skeptics say much of the migration involves small firms that aren’t major job creators or wealthy executives moving for personal reasons. An effort to create a tech hub in Miami during the 1990s dot-com boom withered after the boom turned to bust.

Miami also faces some of the challenges confronting all U.S. office markets in the months to come as they deal with the pandemic and the economic downturn. Leasing activity in the third quarter of 2020 in Miami was “limited as offices sat mostly empty and firms were forced to reimagine their space needs,” according to a JLL report.

A 2020 study by CBRE Group Inc. found that South Florida added 14,700 tech jobs between 2015 and 2019, far below a market such as Denver but on par with one like Portland, Ore.

“We’ve created more of an ecosystem here,” said Shay Pope, a CBRE senior vice president in Miami.

The Miami Downtown Development Authority, an economic-development agency, launched a campaign to court hedge funds in 2013, holding cocktail events in New York and elsewhere. The effort, which later targeted financial and tech firms, scored some successes.
