Azeem Rafiq spoke to the sports editor of the British Broadcasting Corporation.
The Azeem Rafiq racism scandal has led to more than 1,000 people contacting an inquiry into discrimination in cricket.
The Independent Commission for Equity in Cricket opened a call for evidence on 9 November.
Rafiq testified to the MPs on Tuesday about his experiences at Yorkshire.
Cindy Butts said it showed that cricket must change.
Over 1,000 people have come forward to share their experiences with us since we launched part one of our call for evidence last week.
Many people who are inspired by Azeem's bravery have the chance to be heard.
Rafiq, who is from Yorkshire, told the radio station that sharing his experiences of racism at Yorkshire will be the moment that society as a whole moves in a different direction.
He urged anyone who had experienced abuse in cricket to speak out, as he expects the "floodgates" to open.
"You have to come forward and tell the truth and you will be heard," he said.
I'll stand by you no matter what anyone else does.
Rafiq's testimony can leave no one in any doubt that cricket must change, and it must change now, said Butt.
She said that the issues he raised get to the heart of the ICEC's aim of looking into "the culture of the game, the lack of progression of Black and Asian players across the talent pathway and in the professional game as well as the governance and leadership of the England".
She urged anyone who has experienced discrimination to respond to the call for evidence.
Rafiq claimed that "institutional racism" at Yorkshire left him close to taking his own life, and that's when the ICEC was set up.
Butts was appointed chair of the Kick It Out board in March.
The culture of cricket was "archaic" according to a former player and umpire.
He said that some of the things that went off there would never be accepted in any other environment.
It looks like it still is a toxic environment.
Rafiq was found to have been a victim of racial harassment and bullied at Yorkshire, but the club said they would not take action against any player, employee or executive.
Several senior members have resigned, while Nike and many other sponsors have either ended partnerships or said they wouldn't continue deals because of the club's response.
Yorkshire has been suspended from hosting international matches by the England and Wales Cricket Board.
Dawood, who played for Yorkshire in 2004 and 2005, said the club stuck its head in the sand and never tackled the problems of the culture at the heart.
They have never been interested in or accepted that they have a problem. The recent debacle is something that they always felt was better than others.
It's difficult for Azeem to talk about it because it brings back memories of how many of us were treated as subhuman.
The club will address the charge of institutional racism "head on", according to the chairman who apologized to Rafiq and settled an employment tribunal with him.
Azeem has shown incredible courage in speaking out, and we are appalled by what he has experienced. This must be a turning point for our game, as his evidence was harrowing.
There is no place for discrimination of any kind in our game. We must learn lessons from these events, and we are thoroughly investigating them.
In June, Dawood withdrew his employment claim against the ECB after he said he intended to file a lawsuit.
The claims of racism were not upheld, according to the ECB.
The investigations recommended an independent review of the appointment of umpires and that they have implemented several changes as a result of the review and are aiming to reach a target of 15% BAME umpires within the National Panel by the end of the year.
