Startup Idea: Sales Leads Verification Software

Startup idea to build a software that verifies and validates sales leads' information thereby improving productivity and reducing time wastage in chasing false or invalid leads.

For sales, if there is a way to help me find out if information is verified and accurate. I get leads for my job and I often call lines or send messages to false addresses since nothing has been verified correctly. I find that amount of time that it takes to go through these decreases productivity for me.
