Category: ABM / Account-Based Marketing
OSS Maturity:Weak
Build note: Combine Mautic (automation) + erxes/SuiteCRM (CRM) + PostHog (analytics) + n8n (orchestration) to build ABM-like capabilities.
Gap:No dedicated open-source ABM platform exists. This is one of the most commercially-dominated GTM categories.
