About
Clarity was founded by Rebecca Sebastian to partner with organisations and senior leaders navigating growth, complexity and high-stakes leadership challenges. Rebecca works with organisations building leadership capability at scale, and with senior leaders at points where expectations increase, roles expand and the cost of getting decisions wrong is high.
Rebecca brings over 20 years of global experience across leadership, organisational effectiveness and executive advisory. A former corporate executive, she has led global talent and organisational development at TikTok and Bank of America Merrill Lynch, working closely with executive teams and boards across the US, Europe and Asia.
As an organisational psychologist with an MSc from Purdue University, USA and an ICF-certified coach, her work combines psychological depth with a clear understanding of how organisations operate in practice.
Her focus is on sectors defined by rapid growth and regulatory complexity, including technology, fintech, financial services and professional services.
Organisations and leaders typically engage Clarity in the following situations:
Leadership and talent strategy: Designing succession approaches, talent pipelines and development programmes aligned to growth and transformation
Leadership programme delivery: Building capability across senior and high-potential cohorts through targeted development initiatives
Executive transitions: Supporting leaders stepping into significantly larger or more complex roles
Systemic performance challenges: Addressing senior team or board-level issues affecting alignment and decision-making
High-stakes environments: Supporting leaders operating under pressure, scrutiny or complex stakeholder dynamics
Rebecca’s style is thoughtful, direct and grounded in real organisational context.
Based in London, she works with a global portfolio of clients in person and virtually.
