The speed of improvements made by these guys never ceases to amaze me.
If you fall into the majority category of people who want to access and manipulate key data stored and don't know SQL, don't rush to learn it, just use Trevor.
Super attentive to feedback, detail and requests for help figuring out how to query something a little bit "out there" (by non-Techie standards) - as far as I'm concerned, it's a product and service unrivalled for what it's made to do.
We've used Trevor at Trail for over a year and we only rely on it more - the whole team has access to query customer data, and we even run the majority of our customer-facing dashboards & reports via Trevor feeds (with Slemma). Highly recommended.
