The company has been on the lookout for a suitable investor for the London Stadium since the Hammers moved out of the Boleyn Ground in the summer.
The ground, which was until last year still referred to by many simply as the Olympic Stadium, became known as the ‘London Stadium’ last year.
But that name has only ever been a placeholder for the Stratford venue which has been seeking a naming rights partner for months now.
It is reported that E20 are chasing the same potential sponsors as Tottenham Hotspur and Chelsea in efforts to get best deal for the ground.
An Indian car firm were heavily linked with a naming rights deal prior to West Ham moving in to the London Stadium in August, in a move which would have seen the ground renamed the Mahindra Stadium.
Energy drinks giant Red Bull have also been linked with the naming rights deal and own a number of successful clubs throughout Europe.
E20 want a deal worth £4m-£6m per season over a 20 year period for the rights to the former Olympic Stadium’s name.
