The Tigers struggled to survive in the Championship last season, and Pearson has met with potential investors.
Pearson told the club's official magazine: "We have found some people who are prepared to buy in, but it is just a case of getting the balance between release of equity an investment of funds.
"We obviously need to raise money. The money that we managed to bring in last summer and build up through prudently running the company properly was spent without really increasing the asset value of the company.
"Basically we are back to square one and it is not a financial commitment I can find on my own this time. We are going to have to draw on some other people."
