What makes legal360 unique?

We are the most highly recognized business development, marketing, and practice intelligence solution built on the Microsoft Dynamics 365 platform.  This means one platform for your team, no third-party tools, and with pre-built connectors that harvest data from internal and external systems to build your firm’s own ‘Dataverse’.

“How do we get our professionals to contribute their contacts?”  Our integrated ERM and Advanced Contact Processing solution overcomes this obstacle by monitoring Outlook, identifying key contacts, harvesting data via email signature scraping, and assembling the connections to create an invaluable network of the firm’s relationships.

This has been a real game-changer in terms of being able to quickly and efficiently keep our data clean, which is something all law firms struggle with. This tool has saved a significant amount of time through automation and has eliminated mistakes by reducing human interaction.”
