What we do
Experienced leadership.
Accountable execution.
One5 adds executive capacity, independent judgment and dedicated ownership when consequential decisions and initiatives need to move forward.
01 · Interim executive leadership
Maintain momentum.
Choose the right permanent leader.
Step into an executive role with defined authority, accountability and objectives. Maintain continuity while the board or owner evaluates internal candidates, sources external talent and clarifies the long-term leadership mandate.
Use the transition to advance critical work, address difficult decisions and establish a stronger foundation for the incoming leader. An interim with no interest in the permanent position gives the organization time to make a disciplined selection.
Typical mandates: Interim CEO or other C-suite roles, post-acquisition leadership transition, unexpected executive vacancy, and preparation for permanent succession.
02 · Board & executive advisory
Independent judgment for consequential decisions.
Work alongside the CEO, board, investor or executive team to assess options, resolve competing priorities and move decisions into action.
Bring experience and objectivity where internal leadership needs additional capacity or a perspective informed by operating responsibility. Define the decisions ahead, the tradeoffs involved and who will own execution.
Typical mandates: Strategic priorities, leadership and organizational choices, growth decisions, and complex stakeholder alignment.
03 · Transactions & integration
Carry the business case through the transition.

Lead through mergers, acquisitions, integrations, divestitures and separations. Align stakeholders around the intended value and translate transaction decisions into an executable transition plan.
Add leadership capacity from early board discussions and negotiation support through integration or separation planning and execution. Coordinate the specialists involved and keep organizational continuity and business outcomes in view.
Typical mandates: Integration leadership, complex carve-outs, separation planning, and coordination across executive teams and transaction advisors.
04 · Transformation leadership
Lead the initiative.
Buy the right support.
Provide a dedicated executive lead for major operational, financial or technology initiatives. Align the definition of success, resolve tradeoffs and establish accountability across participants who also have demanding day jobs.
Help the organization define, select and manage specialized support. Team size, expertise and cost follow the requirements of the work. Bring clear decision rights and visible executive sponsorship to initiatives that need sustained momentum.
Typical mandates: Enterprise transformation, cost reduction, restructuring, performance improvement and business leadership of major technology modernization.
Work alongside the relevant C-suite leaders, implementation partners and other specialists, with responsibility for connecting their work to the business outcome.
