Former Histon chairman Gareth Baldwin says he is looking to sell his shares in the club as part of a drive to shake up the boardroom.
Baldwin, along with fellow ex-chairman Tony Roach, are keen to see the Bridge Road outfit take a new direction.
"New investment can come to the club and hopefully provide some stability," he told BBC Radio Cambridgeshire.
The Stutes have been relegated from the Blue Square Bet Premier after four years in non-league's top flight.
The club's board currently consists of chairman Russell Hands and directors Angelo Darma, Mac McDonald, Graham Muncey, Colin Pettit and Paul Pleszko.
"It's obviously pretty tough there at the moment," added Baldwin, who spent 18 years at the Stutes.
"It would be very difficult for the club to go forward with its current structure.
"They may be able to stabilise, but I doubt it, and it's likely the club is going to continue to go backwards unless something changes.
"I think the shareholders, who have invested hundreds of thousands of pounds, are looking at their investment thinking 'there's a lot of money, a huge amount of time gone into this project and it's going down the tube'."
Baldwin is currently acting as a commercial consultant at local rivals Cambridge United.
