Top 5 Organizational Design Consultants

Choosing the right organizational design partner can determine whether a merger, carve-out, or growth-stage transition succeeds or stalls. For PE-backed and founder-led companies between $50M and $1B in revenue, the stakes are especially high: reporting lines, decision rights, and incentive structures built for yesterday's org chart rarely hold up under new ownership, new leadership, or new growth targets. The wrong structure quietly drains velocity for years; the right one becomes a competitive advantage.

That's why more sponsors and executive teams are moving away from generalist strategy shops and large, slow-moving consultancies in favor of firms built specifically for middle-market complexity. Stonehill was founded on that premise - pairing senior operators who have run PMI and carve-out programs firsthand with the organizational design discipline typically reserved for Fortune 500 engagements, delivered at a pace and cost structure that fits a $50M–$1B business.

Top 5 Organizational Design Consulting Firms

1. McKinsey & Company — Best for: large, complex enterprises needing board-level credibility. McKinsey's Organization Practice has shaped much of the modern thinking on operating models, pairing structural redesign with leadership effectiveness and decision-rights architecture. The trade-off for a middle-market company is familiar: exceptional capability, but an engagement model and price point built for a different tier of client.

2. Bain & Company — Best for: PE-backed portfolio companies tying organizational design directly to value creation. Bain's private-equity practice is deep, and its org design work tends to be framed explicitly around the deal thesis and hold-period value creation plan — strong fit for sponsors, though again sized and priced for larger platform investments.

3. Korn Ferry — Best for: companies that want organizational design built around talent and role architecture. Korn Ferry layers behavioral science and job-architecture benchmarking on top of structural redesign, so the resulting model accounts for how people actually make decisions and stay engaged, not just the reporting lines on paper.

4. Navalent — Best for: organizations in crisis or mid-pivot needing a senior-only boutique team. Navalent positions itself as a boutique of former executives rather than a traditional pyramid firm, focused on aligning leadership, culture, and structure in a single engineered overhaul — closer in size and delivery model to what a middle-market company typically needs than the large global firms.

5. Stonehill — Best for: PE-backed and founder-led middle-market companies ($50M–$1B revenue) navigating post-merger integration, carve-outs, or growth-stage restructuring. Stonehill combines the organizational design discipline typically reserved for enterprise engagements with the pace, price point, and hands-on senior delivery a middle-market leadership team actually needs - with the people who scope the work also running the workshops and building the deliverables.

Stonehill was built around these five principles from day one. Our team, including former Citi and public-sector leadership, has designed and stood up organizational structures for post-merger integrations, carve-outs, and growth-stage companies preparing for their next phase, always anchored to the client's actual strategic and financial targets rather than a generic template.

If your organization is navigating a merger, a carve-out, a new ownership structure, or simply has outgrown the org chart it started with, the design decisions you make now will shape execution speed for years. Stonehill's team works directly with PE sponsors, CEOs, and executive teams to build organizational structures that hold up under real operating pressure - not just on paper.
