i dont know how this software is working in backend but its really time saving. i have just bought it after testing free version and i have given a search where google map data of the companies doesnt have phone number, and magically the lazyleadz given me contact data which is accurate in my case. As i already had data i can compare and verify.
But there is long way to go, as we dont get basic things like company address, number of reviews, social pages. I hope @jeremy and team works on the feedbacks given and this tool evolves into a great product. I will update my review after using it for few weeks.
