About Me

Hi, I’m Lev Dubinets

I am a Head of Engineering at a fintech company and for years I manually managed Slack and Google groups as my teams evolved. Finally, I put my engineering skills to use and built an app to automate this task.

My background in engineering spans 10+ years across companies large and small and one of the top CS universities in the world. I love building products and I hope GroupSync is as useful for you as it is for me!


Frequently Asked Questions

Can you give me an example of what gets synced?

Sure! If you have a Slack group called @engineers with three people, GroupSync will create a Google Group with those same three people. You can then email, add that alias to a calendar, and do anything else you'd normally do with a Google Group or email.

You can also sync from Google to Slack, in which case GroupSync would look at and create an @engineers Slack group with the same members, which you can use in Slack however you see fit.

If a group already exists on  both platforms, GroupSync will add/remove members to ensure that the group membership is the same on both ends.

What's the best way to onboard to GroupSync with a large amount of users?

If you sign up for the Background Sync plan, GroupSync will immediately sync all your groups over. For some customers with many users, this can come with a high cost. I recommend doing a One-Time Sync initially, and then immediately after signing up for the Background Sync.

Can I use GroupSync to sync Google Calendar memberships?

If you use Google Calendar to have a team calendar, you can simply add your email to any calendar or meeting invite, and have GroupSync manage the group itself. This is exactly how I use GroupSync, and what I built it for!

Can I use GroupSync to sync Slack channel membership?

Not yet, but this is commonly requested and coming soon.

Can I see a demo?

I really should record a demo, but to be honest, it takes less than a minute to sign up and see a preview. You won't be charged to see a sync preview, so just click "Sync your groups" in the top right and sign up :)
