Better decisions when growth creates complexity.
I help family-owned and growing organisations make critical decisions when governance, structure and execution are no longer keeping pace with growth.
When an organisation is moving, but important decisions keep slowing down, the issue is often not effort. It is decision clarity.
I work with leaders to bring structure, challenge and disciplined judgment to critical decisions before confusion becomes costly.
Former Big Four Partner | Risk, Governance and Decision-Making | Advising growing and family-owned organisations on
high-impact decisions
I’m Lucas Gomes Arruda, a former Big Four Partner with over 17 years of experience advising boards and executives on critical decisions.
Throughout my career, I have worked predominantly with family-owned businesses and growing organisations navigating expansion, governance transitions and increasing complexity.
These organisations rarely lack ambition or talent. The challenge is structural: growth creates complexity faster than governance, structure and leadership can adapt.
Earlier in my career, I built and led teams within a Big Four firm, supporting senior leadership in high-stakes environments where decisions carried material financial and reputational consequences.
More recently, working in the UK within a smaller organisation, I have operated even closer to ambiguity, resource constraints and real-world execution challenges.
This combination ensures decisions hold up in practice.
Where I add value
I work at the point where important decisions cannot wait, but the organisation is not fully set up to support them.
Critical strategic decisions
When direction, investment choices or trade-offs cannot be delayed, but clarity is still missing.
Execution without alignment
When teams are moving, but priorities, ownership and decision logic are not fully aligned.
Governance under pressure
When decisions are being tested, but forums, structure and accountability are not yet strong enough.
Growth creating structural strain
When the business is evolving faster than governance, leadership routines or decision-making discipline can adapt.
My perspective was built in demanding environments where the cost of poor decisions was real.
As a former Big Four Partner, I advised in contexts where financial, governance and reputational stakes were high.
Today, I work closer to the reality of growing organisations, where ambiguity is higher, resources are tighter and decisions still need to translate into action.
I understand both sides of the challenge: how decisions should be made, and what actually gets in the way inside an organisation.
That is where I do my best work: bringing clarity when something important is active, but not landing as it should.
