I would say go for it.
From my experience, a company can't be partially remote. Fully remote is a much better option.
Communication breaks down when you do partial remote. Some people would attend physical meetings. The remote ones are out of the loop and a separate remote 'meeting' is needed to update them. The non-remote people are also very unlikely to get on Slack, Jira, or whatever. It falls apart, and you end up with non-remote people handholding the remote ones.
The one fully remote team I worked with was extremely productive. Our Slack had about 20,000 messages a day. People were very good friends with each other; it's amazing how shitposting at 4 AM builds relationships faster than face to face conversation.
We didn't even need meetings. Since we talked on Slack 24/7, it was clear what the next step is for everyone, what everyone was doing, what wasn't being done, and what possible risks crop up.
Other benefits including saving on office space and cost saving of being able to hire top tier people from cheaper countries. 25k Euro annually will net you a good software developer in Lisbon or Kuala Lumpur. Double that, which is about the median for Berlin, and you'll net top tier devs from these countries.
For big things like a full app design workshop or training session, you can still handle them in person, fly everyone in.
Take note that many people can't work remotely. You'll be hiring from a different pool of recruits, the ones who prefer remote.
I'm in the office before sunrise, back home at sunset. 7 to 7 sounds crazy, but there are naps in between, playing with the kids, and plenty of rest. I know a guy who does two 3 hour batches in the day, and 2 hours at night, and does grocery shopping or laundry in between, during his rest. You also get the night owls who are happy working 6 PM to 6 AM.
For that reason, we had stand up meetings at 6 PM, where one group clocked out and another group clocked in. Side benefit was that we could assign one group work at night and the management team did code reviews in the morning. When the night team was exhausted, a fresh pair of eyes might spot a solution they didn't see, and vice versa.
p/s if you want to leave a country just to avoid taxes, Malaysia offers entrepreneur visas. Top of corporate and income tax here is about 25%.
