Salentica's take:  Seismic's roots are in the asset management industry, originally being solely a document automation tool.  Seismic has gone on to build a strong platform on the theme of "the right content at the right time."  Key features include the ability to generate personalized sales and marketing collateral based on the attributes of your recipient (client, prospect, influencer, etc.) and to see tracking, analytics. Ultimately the tools are designed to help client-facing and prospect-facing team members be more effective and save time.  Seismic's integration for Dynamics 365 can leverage data inside Salentica Engage to accomplish this personalization.  Their LiveDocs technology can assemble documents and presentations from disparate data sources on-demand.
