Leadership advisory and executive coaching for senior leaders and founders
Partnering with leaders navigating scale, transition and organisational complexity
Areas of focus
We provide targeted engagements for leaders navigating changes in scale, responsibility and organisational complexity.
EXECUTIVE ADVISORY
Best For:
CEOs and C-suite leaders with enterprise-level accountability, global scope or complex organisational mandates.
Focus:
A sustained, high-trust and discreet partnership for leaders operating at the top of the organisation. This is a rigorous sounding board for complex situations, not a development programme. We examine how you exercise authority, make high-stakes decisions and shape organisational performance.
Impact:
Clearer, strategic judgement in complex situations.
Stronger decision-making at enterprise level.
Leadership that matches the scale and demands of the role.
FOUNDER ADVISORY
Best For:
Founders scaling organisations through institutionalisation, private equity investment, Series C/D or pre-IPO.
Focus:
Strategic support for founders as their role shifts from hands-on builder to leader of a complex institution. We address the practical implications of scale, including changes in control, delegation, managing competing stakeholder priorities, decision-making and leadership style.
Impact:
Reduced dependency on the founder in day-to-day operations.
Stronger leadership layers and clearer accountability.
Leadership model built for institutional growth.
LEADERSHIP TRANSITIONS
Best For:
Leaders stepping into new roles such as first-time C-suite roles, CEO positions, board appointments or significantly broader remits.
Focus:
An intensive, time-bound engagement focused on reducing risk and accelerating effectiveness during the first 90–120 days. The program focuses on understanding stakeholder dynamics, navigating organisational politics and establishing authority quickly so you can lead with credibility from day one.
Impact:
Building faster stakeholder alignment and influence.
Strong early authority and credibility.
Reduced risk during high-exposure transitions.
TEAM DEVELOPMENT
Best For:
Leadership teams, high-potential cohorts and senior teams needing to strengthen collective effectiveness or develop specific capabilities.
Focus:
Custom-designed programs addressing team dynamics, communication and leadership development. This includes team effectiveness work focused on alignment, conflict and decision-making, high-potential programs and workshops on difficult conversations, strategic influence and leadership presence.
Impact:
Improved communication, conflict navigation and team alignment
Stronger decision-making and collective effectiveness
Accelerated leadership development across cohort
Working together
Engagement design
Each engagement is tailored to the individual or organisation, depending on what will be most effective. This may take the form of:
Ongoing advisory: A monthly retainer providing consistent access and support
Time-bound engagements: Structured work over a defined period, often aligned to a transition or specific objective
Targeted interventions: Focused work on a particular challenge or moment
Team engagements: Bespoke work with senior teams to strengthen alignment and performance
Initial conversation
We begin with a confidential conversation to understand your context, what you're navigating and whether there is a strong fit.
Delivery
Work is delivered in person (London-based) or virtually, depending on location and preference.

About us
Clarity was founded by Rebecca Sebastian to partner with senior executives and founders at pivotal moments where scale, complexity and responsibility fundamentally change the requirements of leadership. In high-stakes environments, Clarity provides the reflective space and psychological rigour required to lead with precision.
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 functions 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 and an ICF-certified coach, Rebecca combines psychological depth with an acute understanding of how institutional systems operate. Her practice is focused on sectors defined by rapid growth and regulatory complexity - specifically Technology, Fintech, Financial Services and Professional Services.
Leaders partner with Rebecca when the stakes are high. Her work most often involves:
Executive Transitions: Navigating the shift into materially larger or more complex global roles.
Scaling & Institutional Growth: Supporting founders and CEOs as they move from hands-on operations to strategic enterprise leadership.
Systemic Performance: Addressing senior team or board-level challenges to strengthen alignment and decision quality.
High-Stakes Scrutiny: Providing a discreet sounding board for leaders operating under intense public or regulatory pressure.
Rebecca’s style is known for being thoughtful, direct and operationally grounded. Based in London, she works with a global portfolio of clients both in person and virtually.
