Portsmouth have agreed a deal with telecommunications firm OneCom that could net the club up to £100,000.
Hampshire-based OneCom will directly invest £30,000 into the League Two outfit, as well as making further donations to the club's Supporters Trust every time a Pompey fan signs up to their services.
OneCom chief executive Darren Ridge told reporters: "I'm a Pompey fan and I'm delighted to be able to support the club in this way.
"At OneCom we're keen to find ways to give back to the community and this was too good an opportunity to miss.
"I'm pleased that we have tied up this deal in time for the first game of the season and I'm looking forward to continuing to support the club in what we hope will be a fantastic first year as a fan-owned club."
OneCom was formed earlier this year as a result of a merger between Premier Telecom and Business Phones Direct.
