Great
thanks Jogo, pretty much as I thought. just wondered if you were using forecast or actual.
I also struggle to work out margins.
Companies report numerous different metrics on "margin". EBTDA margin, gross margin, margin on some earnings but not all etc etc. I am not smart enough o be able to work out the difference myself. Im working on upskilling!

The additional aspect for SaaS companies is the marked difference in companies with average vs great retention rates.
Joe Magyer talks a lot about this. https://www.lakehousecapital.com.au/2019/02/08/3-key-insights-from-the-worlds-premier-saas-event/ and how to interpret retention rates in varying stages of a company's development.

So I am working on a multiple that could be applied to either your or Rokewa's output.

My guess is a non-linear multiple: for example retention rate squared, which will give an exponential difference between average and good retention rates.
Although there are numerous other factors that I try to be take into account the other biggy for me is how that growth is being bought.
i.e. what the cost of achieving that growth is. I hate buying into fast growing companies that constantly have to have CR to fund growth and you are never actually sure are going to become profitable (mini Ubers). Some metrics are easy to interpret such as Nearmap giving a group sales team ratio, for others the expenditure vs revenue ratio gives an indication of whether an inflection point is being reached (https://mattjoass.com/2018/11/10/inflection-point-investing/)
Anyway
Thanks to you guys for your input and good luck with your holdings. Hope you enjoy the articles.
BTW as a result of the above exercises EVS, BTH, STG, RBL, ELO come out favourably
