The PERSUIT platform has the ability to invite up to 100 firms in a single request. There is no limit as to how many contacts the request is sent to within those invited firms.
If you would like to invite more than 100 firms, we recommend creating multiple requests. You can reach out to your organization's CSM if you have any questions regarding the best way to structure those requests.
You can also find more information on how to create and publish a request through this article.
