Strategic advisory for mid-market CEOs navigating complexity, growth, and transformation.
Harris | Allison is a strategic advisory firm that serves mid-market CEOs and growth-stage companies with revenues typically between $10 million and $500 million. Founded by Bill Harris, the firm combines senior executive experience with a proprietary methodology called the Trust Operating System™ to help organizations transform how they think, move, and perform.
Unlike traditional consulting firms that deploy junior staff, Harris | Allison engagements are led by senior partners who bring decades of operational experience directly to client challenges. The firm's approach is implementation-focused: we don't just advise, we help execute.
Harris | Allison serves mid-market companies - organizations large enough to face enterprise-level complexity but without the infrastructure of a Fortune 500. These companies are often founder-led or private equity-backed, navigating growth inflection points, leadership transitions, or operational transformations.
Leaders of companies between $10M-$500M in revenue who need strategic clarity and operational execution support without the overhead of Big 4 consulting.
Portfolio companies requiring rapid value creation, operational improvements, or M&A integration support with experienced operators, not just advisors.
Organizations navigating leadership succession, preparing for exit, or professionalizing operations while preserving what made them successful.
Organizational transformation requires more than strategy - it requires structural trust. The Trust Operating System™ provides the architecture for organizations to maintain coherence under pressure and execute with alignment.
Common data and interpretive frameworks that ensure everyone operates from the same understanding of reality. No hidden information, no competing narratives.
Consistent vocabulary and definitions across the organization. When everyone means the same thing by the same words, execution accelerates.
Aligned rhythms, rituals, and decision-making processes. Predictable patterns that maintain organizational coherence through change.
Every engagement is led by experienced executives who have operated at scale. You get decades of pattern recognition applied directly to your challenges.
We don't deliver slide decks and disappear. We stay engaged through execution, ensuring recommendations become operational reality.
Our proprietary methodology addresses the root cause of organizational dysfunction: lack of structural trust. Not team-building exercises - architectural change.
Human judgment amplified by intelligent orchestration. Our proprietary platform accelerates analysis and ensures nothing falls through the cracks.
