CRM, email and social marketing company InfusionSoft has closed on a $54 million round of funding led by Goldman Sachs. The company competes with Eloqua (recently purchased by Oracle for $871 million) and HubSpot (recently closed a $35 million round) in an intensifying CRM / marketing automation field, with much attention going to small and midmarket companies. InfusionSoft plans to use the cash to educate small businesses and add functionality to its CRM and lead generation services.
