I am incredibly grateful to have found AA-ISP (after reading Trish Bertuzzi's book "Sales Development Playbook") and it has been a great resource in the short time I have been using this website. I am a new manager of an inside sales team. My team has been using extremely low quality data for prospecting. I need a new data source, and was wondering who is the best provider of data? My company is in the IT service/consulting space.
