Fractional CS/PS Leadership

Who It's For

Built for companies that need the leader now and can't wait out a search.

The usual triggers are a VP who left, a team that grew faster than its management layer, or a sponsor that wants post-sales fixed before the next board meeting. A full-time search for a VP of Customer Success or a CCO takes months, and the team still has to run in the meantime. Fractional leadership covers that gap, and it often clarifies what the permanent role should look like.

Good fit

When fractional leadership makes sense

  • The head of CS or PS has left and the search will take months.
  • The team grew faster than its management layer.
  • A PE-backed company has a post-sales turnaround on a deadline.
  • A founder-led company is ready for its first post-sales leader and wants to get the role right.
Scope

What Jeff owns

  • Leadership team meetings and post-sales reporting to the CEO and board.
  • Day-to-day management of CS, implementation, PS or support staff.
  • Escalations and executive conversations with customers.
  • Process, playbook and tooling decisions for the post-sales team.
  • Weekly work product the team can put to use immediately.

How It Works

How a fractional engagement runs

The engagement is scoped to the problem, and it runs on the company's own operating cadence.

01

Scope

We agree on the teams Jeff will lead, the decisions he owns and how the company will measure success.

02

Embed

Jeff joins the leadership meetings, the team's operating cadence and the open customer escalations.

03

Deliver weekly

Every week the company gets work product the team can use, such as playbooks, reports, process fixes and coaching.

04

Hand off

When the permanent leader starts, Jeff hands over the operation, the documentation and the plan.

How It Compares

Fractional leadership and advisory are different engagements

Advisory gives a CEO or CS leader a senior thinking partner while the team does the work. In a fractional engagement Jeff is in the seat, so he runs the meetings, manages the staff and owns the deliverables.

Common Questions

Questions about the fractional engagement

What does fractional CS or PS leadership look like day to day?
Jeff acts as the functional team lead. He attends leadership meetings, works directly with customers and stakeholders, oversees CS or PS staff and delivers weekly work product. When something needs to get built or a customer call needs a senior voice in the room, that is part of the engagement.
How is fractional leadership different from strategic advisory?
In a fractional engagement Jeff leads the team and owns the deliverables. In an advisory engagement he meets weekly with the CEO or CS leader, who keeps ownership of the team and the decisions.
Which functions can a fractional leader cover?
Jeff covers customer success, onboarding and implementation, professional services, support and renewals, in any combination the company needs.
Do you work with PE-backed companies?
A significant share of our work is with PE portfolio companies that need a fast post-sales turnaround, and fractional leadership is often how that turnaround starts.
What happens when the company hires a permanent leader?
Jeff hands over the operation, the documentation and the plan so the new leader starts with a working team.
