However, Mashaba denied rumours that among the prominent people soon to be announced is Gauteng EFF provincial leader Mandisa Mashego who has fallen out of favour with the party leaders.
"I have never spoken to a single individual in the EFF," said Mashaba, who formed The People's Dialogue in December after resigning from the DA following Helen Zille's appointment as DA chairperson of the federal council.
Not long after Mashaba's resignation, Maimane also stepped down.
The two hinted that the possibility of working together but this did not materialise.
Boughey said his decision to join Mashaba was not about "choosing one over the other".
"It is not a question of choosing one over the other. I have great respect for Mmusi and I am very close to him," Boughey said.
"At this stage Herman and Mmusi decided to pursue the ventures that they did. I am hopeful that going to the future there might be a coalition or a coming together at some stage."
Boughey move to The People's Dialogue is a big political catch for Mashaba.
Boughey spent five years as the CEO of the DA but had also worked with other party leaders such as Tony Leon and Zille.
