Investment analyst / researcher

I want to develop a database of all the SaaS B2B marketplaces like hubspot app marketplace, salesforce app exchange, athenahealth Marketplace etc. I need you to use google, chat gpt, perplexity to develop a comprehensive list (there are over 600 of them). And for each marketplace, I will specify specific characteristics to input e.g. type of customers they serve, the number of apps on the marketplace, the growth of the marketplace etc.
