Bertrand is leading the group alongside British technology expert Omar Mir, who is the sole funder of the proposed minority share buyout through investment vehicle Sloane Street Capital (SSC).
AFC Wimbledon have been fan-owned since their inception in 2002 as a phoenix club after the original Wimbledon FC were relocated to Milton Keynes.
The Dons Trust continues to hold a controlling stake in the club, owning 50.01 per cent of the voting shares, and the board presented the consortium’s proposals to its members on Wednesday night.

Under the terms of the deal, the Dons Trust voting rights would be unaffected. They would also hold veto control of the Cherry Red Records Stadium freehold, while SSC would take two of the 12 seats on the club’s board.
The Dons Trust would also retain a veto over the club's name, badge, colours, ground and constitution.
Dons Trust members have until November 17 to vote on the proposal, which is one of 20 they have received since voting earlier this year in favour of external investment on the condition that the club remains fan-owned and controlled.
On the proposal, Bertrand said: "AFC Wimbledon's story is unique in English football and it was built by its supporters. We felt at home from our very first meetings.
"We are not here to change what this club is. We are here to help it go further on and off the pitch, for the men's team, the women's team and the academy.
"It would be an honour to join the Wimbledon family and help write the next chapter, and we look forward to meeting members and answering their questions over the coming weeks."
Angus Fox, chair of the Dons Trust board, said: "The deal brings at least £87m into AFC Wimbledon over five years, while the Trust keeps a permanent majority of the votes, control of the Plough Lane freehold and a veto over everything that makes us who we are.
“We have set out the factors to weigh as plainly as the opportunities. The board recommends a yes vote, but this is our members' club and our members' decision."
