Yes you can, if you can afford it. You'll have a product team for each product, product areas for each group, and verticals for security frameworks and auditing and the like.

I've successfully worked with 30+ concurrent product teams (of 6-12 devs each) in the past so yes, it can definitely be done. We would build huge systems. It's a nightmare if you're a stakeholder for every team of course so you need to have a team to delegate leadership as well. In the end I had 6 product area managers and a handful of architects that would be responsible for the overall ecosystem between them as a technical leadership team.

Managing a successful suite of products isn't an issue, the issue comes when you start having non-performing products and you start facing pressure to cut costs. This is where things can get shitty quickly. If you want to compare to Google, think Google Plus.

Their service is great, no doubt, but let’s not forget about this.

Proton Mail Discloses User Data Leading to Arrest in Spain #531039

Yikes might need to abandon the Google ship! Google Sheets was the only think kind of keeping me there.

A good spreadsheet is hard to find. I use Libre on my Linux and it’s terrible at times. It won’t even do simple functions like sum!

I like my spreadsheets like I like my porn: Safely on my computer. This won't make me give up LibreOffice, that's for sure.

One thing worth remembering about Google's growth is that they also killed products when they thought they weren't worth it (Reader still pisses me off). I'd imagine Proton's got the same plan if this fails.

I use only the proton mail for some specific throwaway emails / services. I do not rely on their services because I have enough of my personal servers and services.

I think they can as long as they don’t stray too far from the core product offers.

In short, yes. If they grow their team in a healthy way. Google is very good at security. They just don't care about privacy. Their addition of apps makes sense to me as well. People want to replace Google. The reality is it takes a suite of apps to do that.

Caveat. I would have the same concern as you. Many companies struggle with growth.

FWIW I have only ever used and trusted their email service. They did buy simplelogin which I used prior to the purchase. For the office apps I self host Nextcloud and there are good companies like Federated Computer for those that can't self host. But I don't use Spreadsheets in Nextcloud. I stick to Libre Office which is great and if I need to share I can use Nextcloud or Syncthing.

Yeah, I always dislike when companies start small, in a niche, but then start expanding and spreading themselves thin. Personally, I don't like it. Do one thing and do it well.
