Ms. Podesta, who runs a lobbying firm with dozens of corporate clients, including Apple and Yelp, said she had seen a surge in interest in her Democratic-leaning firm, signing up new clients in recent weeks in advance of an expected Biden win.
“The real shift will come in December,” she said. “It takes a while for Fortune 500 companies to make these decisions.”
Others well positioned to profit in the Biden era include the lobbying firm owned by Jeff Ricchetti, the brother of Mr. Biden’s campaign chairman and incoming White House counselor, Steve Ricchetti, and a firm co-founded by Jeffrey Peck, who worked on the Senate Judiciary Committee under Mr. Biden and served as treasurer of the Biden Foundation.
Mr. Peck deregistered as a lobbyist early this year, but the firm that bears his name continues to do a brisk lobbying business, adding clients like the International Franchise Association in the months before the election.
The Biden administration is also expected to generate new business for firms with connections to Mr. Biden or his team that help clients get their way in Washington without formally registering to lobby — including WestExec Advisors and Albright Stonebridge Group, as well as Beacon Global Strategies. Beacon Global, which has represented Raytheon and Citi among other clients, was co-founded by Jeremy Bash, a former Obama Defense Department official who has worked closely with Mr. Biden’s newly named White House chief of staff, Ron Klain.
Precision Strategies, the self-described “integrated strategy and marketing agency” co-founded by Mr. Biden’s campaign manager and incoming deputy White House chief of staff, Jennifer O’Malley Dillon, was retained starting in August to do public relations work by the American Investment Council, a lobbying group representing private equity firms.
One of the most prominent of these firms is SKDK, which provides communications and fund-raising advice to corporate, political and foreign clients, including the Biden campaign, a super PAC started by the former New York City Mayor Michael R. Bloomberg, and an Israeli spyware firm. (SKDK has registered under lobby laws in the past, but it says that was for public affairs consulting and that it does not lobby.)
