Towles Consultancy
I help growth-focused and investor-backed businesses accelerate revenue performance, strengthen commercial capability, and build the leadership infrastructure required for sustainable scale.
Currently taking on a small number of new fractional and coaching engagements.
I'm Sarah Slack, Managing Director of Towles Consultancy. Two decades in commercial leadership have taken me from building sales organisations from scratch to turning around functions that had stalled — always with the same focus: teams that perform, and growth that holds up under scrutiny.
These days that experience goes to work fractionally. Founders, boards, and investors bring me in at the point a business needs senior commercial leadership but isn't ready for — or doesn't want — a full-time hire, and I step into that gap directly.
The route there varies: sometimes it's growth, sometimes a transformation that's overdue, sometimes getting the business investment-ready. What stays constant is the standard — decisions grounded in experience, and outcomes you can actually measure.
Turning ambition into a repeatable plan for accelerating growth.
Rebuilding commercial functions so they hold up under real pressure.
Raising what a sales team is capable of, not just what it's doing.
Turning strategy into a plan the business can actually run.
Building leaders who can hold a room and hold a standard.
The judgement calls that decide how a deal really lands.
Aligning structure and accountability around what's needed now.
Raising the bar without knocking confidence.
Engagements are shaped around whichever of these is most needed right now — often more than one, working together.
