Leadership isn’t linear. Your support shouldn’t be either.

At Sullivan Collective, we work with founders and leadership teams across all stages of growth – early traction, rapid scale, strategic inflection points, and everything in between.

We don’t offer off-the-shelf solutions. We create space – for clearer thinking, sharper decisions, and more focused execution. Whether you need a reset, a steady hand inside the business, or a trusted sounding board, our services are designed to meet you where you are – and evolve as you do.

Strategic Audit

Recalibrate your strategy. Refocus your team. Move forward with confidence.

A structured review to unlock clarity, align your operational focus, and set priorities that actually stick. Includes a strategy workshop, a tailored plan, and quarterly check-ins to keep things on track.

Fractional COO

Get your business out of the weeds. Build the engine that drives scale.

Hands-on, embedded operational leadership to drive structure, focus and delivery. For when you need momentum and maturity – but not a full-time hire.

Leadership Mentoring

High-trust support for the person steering the business.

Confidential, strategic mentoring for founders and senior leaders. Think: perspective, decision support, and calm in the chaos – without internal politics or performance.

Executive-led Projects

Strategic support for companies navigating major change.

Confidential, senior-level guidance for CEOs and leadership teams during M&A, restructures or operating model shifts – bringing clarity, alignment and a steady hand through complexity.

The spaces we create

Our work creates space – for leaders to operate better, teams to align faster, and businesses to scale with more intention.

Space to think clearly.

Space to step back from the day-to-day.

Space to grow into your next chapter.

Space to lead with confidence.

Whether we’re reviewing strategy, embedding in operations, or mentoring through high-stakes decisions, the space we create gives leaders room to breathe – and the structure to act.

Flexible by design

Our programs are built to be flexible and interchangeable. Need a strategy reset that rolls into fractional support? Done. Want to combine mentoring with operational input? Let’s shape it around you.

Because the reality of growing a business doesn’t fit into clean boxes – and your support shouldn’t either.

Let’s build your next move – together. Let’s talk.
