Does anyone have a good read on what their revenue growth rates are?? In their prospectus it shows that their revenue from 2018 - 2020 declined but this is due to the transition to SAAS, which I can understand.

However, they did not provide any data pre 2018, which I wanted to assess to understand the underlying revenue growth prior to any transition to SAAS. Anyone know where do I go to look for that info?? Is it 10 growth? 20% growth? No growth??
