How many companies are listed on NEO?

Could you please clarify for me how many businesses are currently listed on the NEO blockchain platform? I'm interested in understanding the scale and diversity of the NEO ecosystem, and the number of companies listed seems to be an important metric in assessing that. I'm also wondering if there's a way to easily access this information, perhaps through an official channel or a trusted third-party source. Could you provide any insights into this matter? Thank you in advance for your assistance.
