SENECA Investments has taken a stake in Yorkshire recruitment business PSI Energy.
Tadcaster-based PSI provides skilled contractors, consultants and full time staff to the oil and gas industry.
PSI director Rebecca Langrick, represented by Jonathan Simms from Clarion, said: "Our growth has been hampered recently due to the political unrest in the Middle East and the lack of mainstream funding available for SMEs to break into export markets.
"We particularly admired the speed in which Seneca put the deal together. It will allow us to set up in new markets worldwide and look at acquisition opportunities for bolt on to PSI."
Seneca Investments was launched last year focused on making equity investments in SMEs facing financial difficulties.
