tetrate.io Reviews 

I received an unsolicited call from someone claiming to be from Tetrate. I'm relatively certain this person was cruising LinkedIn for potential clients and using a plugin that links phone numbers that have been harvested through dubious means. He knew my first name, employer's name and phone number, which isn't listed publicly.
When asked he was cagey about where he obtained my phone number. When he established I wasn't immediately going to go into his sales funnel, he hung up on me mid sentence. Clearly no idea about building relationships and how the contacts of today could become the clients of tomorrow.
I would avoid this company if contacted by them.
