Why idenflow exists
I was done doing this by hand.
For more than eight years I have worked with Google Workspace, for companies such as HelloFresh: first as an IT manager, later as product
owner. Today, as a freelancer, I set up and run Google Workspace for new clients.
At HelloFresh I saw how fast a company can grow:
about 5,000 employees when I started, and 25,000 user accounts when I left.

In Germany alone, around 50 people joined in a typical month and 10 to 25 left. Done by hand, every one of those cases is a ticket: written,
read, carried out in the Admin console. Things are easily forgotten. And an exit handled too late is a
security risk.
Over the years I have administered IT, led it and automated it, always working closely with HR and management. I know Personio from
working with HR, and Google Workspace from running it.
That is how I saw the gap: Personio knows who joins, moves and leaves. In Google Workspace, someone has to carry it out. And nobody owns
that hand-over.
At my next employer, again on Personio and Google Workspace, I started closing that gap. A rudimentary version of idenflow that I
had set up in the meantime ran there: Google followed Personio, with no ticket in between.
Alongside it ran a tool of my own that backs up leavers' mail and Drive from Google Vault before the licence goes. As of November 2026,
the tool had completed 267 of 269 accounts and backed up 5.2 TB in
about 4.8 million emails and files. The licences it freed up cost
about €29,800 a year.
My goal is to save as many companies as possible the time these tickets take, so they can focus on what matters. That is why I rebuilt
idenflow from scratch: for many companies, not just one.
I build and run it myself. When you get in touch, you talk to me.

Who left but is still active in Google?
You connect Personio and Google Workspace and see where the two do not match.

About an hour, set up with us; you need Personio Core Pro and a super admin.
Nothing is written to Google before you approve: rules start on review, playbooks stay off.
Status: built and tested, not yet in use at any customer. We will offer the free
check once idenflow runs in production; you can request it now. To hear when idenflow is
available, join the waitlist.
Pricing is on request during the pilot phase. Write to us through the form. You can work out
above what slips through at your company today, with your own numbers.
Do we need an identity platform?
No. The connection runs directly from Personio to Google Workspace. Single sign-on and multi-factor sign-in for other apps are not part of
idenflow; for those, an identity platform remains the right tool.
Couldn't we automate this ourselves?
Yes, with general automation tools. You then add approvals, safety limits and logging to every flow yourself, and whoever built your API
calls maintains them when Personio or Google change. In idenflow, all three are built in.
What if something in Personio is wrong?
Personio is the reference, so a wrong value becomes a planned change. If the rule is on review, you reject it; it does not come back while
nothing changes. The fix goes into Personio.
What data does idenflow process, and what does the works council get?
From Personio, core data such as name, status, start and leaving dates, department and manager; from Google, a copy of each account's
directory record. For data protection and the works council, idenflow generates a
system description from your configuration.
Is idenflow available in German?
The app's interface is in English for now. Mail templates are kept per language, and each person gets the one in their language, or the
English one otherwise.
