As new opportunities surface, or government regulations come down, businesses see the need to reinvest in their systems, he said.
"The temp industry starts to pick up as recession starts to end," Karpf said.
On Friday, the Department of Commerce reported that investment in durable goods, such as communications equipment and computers, rose 4.1% in August after a 5.3% drop in July.
Karpf said the acquisition of Danville-based Partners in Business Inc. expands his company's role in the IT-rich Bay Area market. The Glendale-based firm has 600 employees, with offices in North Carolina, Arizona, Texas and Florida.
Karpf said Partners in Business emphasizes consultants and specialists, while his firm traditionally is stronger in workforce staffing.
"The business mix was different, which was perfect," he said.
Merger talks began in January and were completed at the end of August, he added.
Karpf declined to reveal the names of SMCI clients, but Partners in Business lists employers including the American Bankers Assn. and the Department of Labor.
Even with the temp business up, Karpf said economic uncertainty lingers.
"We are not sure we are out of the recession yet," he said.

"On the permanent-hiring end of things, companies are a little uncertain about what is happening at the government level," Nakamoto said.
Meanwhile, Karpf has one piece of advice for IT job seekers: "Java developers are worth their weight in gold.
