The other thing is: I have no idea who you are, so why would I hand over my Google Analytics information to you? You have a client list, but no general "about" page, no information about your team, etc.
In its current form, I wouldn't trust this one bit.
EDIT: I see from an above comment that it's a new product. Fine. Still: work on your credibility if you don't want to be confused for a phishing attempt.
EDIT2: For anyone wondering, it's definitely legit, see the added LinkedIn profile. Nice work!
As for handing over GA info, it's only handing it over to Google as they handle all login and authorization. The data can only be seen by you and is not accessed or stored on our side. However, someone else voiced the same concern, so I will definitely make it more clear.
I have been working in the field of web analytics for many years but this is a brand new site (old one was at akravitz.com) About page is coming!
