Subscription revenue if I correctly recall is currently around $30-50k/month. It should at least double with the introduction of option for live pricing on all pages and no doubt a handful of additional incoming improvements+benefits like the recently introduced 15 free trades with yearly subscription.
Having a subscription myself has actually resulted in most of my best trades, by learning from the portfolios and trades of the best performers. It took time learning how to use the Analysis and Research features, but 100% worth having access to that data.

As to Raiz, I've recently had two friends migrate from it to SelfWealth. Main reasons being Raiz is not CHESS sponsored and my friends wanted the option to buy/sell any shares, not just a limited number of ETFs held in trust by Raiz.
