Sales and marketing are often considered a single category on a business plan, but ironically, when it comes to building apps and services to help with them, they usually become separate entities, and so too do the teams that address sales and marketing in organizations. Today, however, a startup called Terminus — which is building a platform that views sales and marketing in a more integrated way, through account-based marketing — is announcing funding and growth, a sign of how its approach is gaining more traction. The startup has closed a Series C of $90 million, at a valuation we understand from sources to be around $400 million.
