Andrew Wilkinson is someone I've heard of (see his tweets across my timeline every few days), and so his signal gets boosted a lot in trendier tech circles.
Another Canadian company ("Berkshire Hathaway" of software) is Constellation Software. $3.1 billion in revenue in 2019 and is publicly traded [1]. They too are interested in buying SAAS companies and internet properties. I didn't hear about them until I came across it randomly (again on Twitter).
Does anyone know if there's a compiled list of these kinds of operations (software holding co's / Berkshires of SAAS type of thing)?
