Unresolved leadership gaps stall execution and weaken succession pipelines.
High-potential executives rarely fail due to lack of talent.
They fail when leadership gaps disrupt succession, retention, and execution at scale.
Executive Accelerator is a 9-month leadership upgrade for high-potential executives operating under real strategic and organizational pressure.
It accelerates decision clarity, executive alignment, and execution at scale.
Convert high-potential executives into high-impact decision-makers
without pulling them out of the business.
Over 9 months, executives engage in three immersive retreats designed to sharpen judgment, strengthen leadership posture, and improve decision quality, while staying fully accountable for day-to-day execution.
Three immersive retreats (3 × 4 days) – offsite, execution-focused
360° Leadership Assessment – baseline, progress tracking, sponsor visibility
1:1 Executive Coaching (8 sessions) – applied to live business challenges
Peer Leadership Calls (8 sessions) – pressure-testing decisions with equals
Private Executive Network & Custom GPTs – ongoing strategic leverage
A diagnostic and development framework designed to surface the real constraints limiting executive effectiveness over time.
Five measurable pillars, evolving over time. We’ll assess your starting point, and you’ll see your leadership radar shift as the retreat progresses.
Executive Accelerator Timeline
Preselection, Alignment & Leadership Baseline
Sponsor alignment, executive casting, and leadership diagnostics (including 360°). This phase establishes a clear baseline, decision priorities, and success criteria before entering the program.
Retreat 1 – Leadership Under Pressure
Executives work on reactivity, decision patterns, and leadership behaviors under real constraints.
Live feedback, individual and group work sharpen judgment, presence, and personal leadership impact.
Retreat 2 – Executive Impact & Influence
Focus on authority, courageous conversations, and influence at scale.
Executives clarify their leadership stance, align values with strategy, and strengthen communication in high-stakes situations.
Retreat 3 – Enterprise Leadership & Strategic Voice
Executives consolidate their leadership positioning beyond their role. They finalize strategic priorities, practice executive-level communication, and strengthen their impact across the organization and governance layers.
Executive Outcomes & Transition
Executives deliver a clear strategic narrative and leadership roadmap.
Final sessions support integration and transition into the On a Quest executive network.
