As a remote company, what benefits do you offer to your remote team members to keep them engaged?

Curious to hear from the network!

Working fully remote has enormous advantages. I've been doing it for the last 3 years.

Yet at the same time, when you have remote employees and/or contractors, it might be difficult to keep them engaged and committed to your company long-term. Especially when competing with on-site companies that offer various "office perks" and benefits, that often are appealing to workers.
Due to being remote, it's not always possible to offer equal benefits. E.g. because the company is not registered in a specific country.

How do you make sure that you keep your remote team members engaged and satisfy their needs for social benefits?
Do you use any specific tools or services to accommodate and keep track of it?
