A total of 240 companies have already signed up the "Valuable 500" business-led initiative, which aims to get 500 top companies to commit to including those with disabilities.
Inclusion campaigner and Valuable 500 founder Caroline Casey said she was very emotional about the success of the movement so far.
She said the movement, which had its genesis in the O2 Ability awards, was actually launched at Davos last year amid an "absolute belief" that it could achieve its aims.
Valuable 500 aims to unlock the business, social and economic value of the 1.3 billion people living with a disability, the largest minority group worldwide.
Caroline Casey said 240 companies around the world have signed up - with the signatures of their chief executives - including companies in Japan, the UK, the US, India, Israel and Mexico. 13 companies from Ireland have also signed up to the initiative.
Ms Casey said that represents €3.6 trillion in business revenue and just under 10 million employees across 22 counties and 42 sectors. She said it was a "tipping point for change".

The inequality crisis for people with disabilities can not be solved without business, Ms Casey said, adding that in 2020 companies just can not leave 15% of the global population out of business.
She said there is no doubt that the digital revolution is leading the way with social media giving a voice to people with disabilities that they have never had, while Ms Casey also said that young people says that inclusion means inclusion for all.
She says there is a reluctance among business on the issue because there is a lack of understanding as well as a fear of getting it wrong and a fear of causing offence. That fear is stopping the conversation from even starting, she said.
But in order to avoid risking their brand, she said that companies must start down the path of inclusion.
