The Head of GTM Engineering (Digital Success) is Apollo’s first architect of a scaled, AI-native digital success motion. This leader takes ownership of customer outcomes post-onboarding—where activation is scored, but expansion, pipeline generation, and digital orchestration remain untapped. This role is part strategist, part system-builder, and part revenue architect. They will design the Digital Success Engine for Apollo: orchestrating agentic adoption loops, outbound virality, contextual upsells, and cross-functional programs that convert onboarding momentum into sustained revenue impact. Core mandate: make Apollo customers successful by making them generate more pipeline, more meetings, and more sales—faster—via digital-first interventions.
