How to Build a Fractional Consulting Business for Nonprofits Through Your Network

Everyone talks about cold outreach, LinkedIn funnels, and lead magnets. Tracey van Marcke did none of that - and she's been running a thriving fractional COO practice serving nonprofit leaders for five years.

Her business grew entirely through her network. Projects turned into retainers. Clients who loved the work started pitching her on new things. When one engagement wound down, something else always appeared. Somewhere along the way, she became the "right-hand executive" to nonprofit CEOs who couldn't afford a full-time COO but desperately needed someone in their corner.

This post breaks down how she built it, what she's learned about managing fractional client relationships, and the specific red flag that gets her off a prospective client call every time.

The short answer:

The most sustainable fractional consulting businesses for nonprofits are built through relationships, not funnels. Start with your existing network, let project work become retainer work, and manage the natural rhythm of client engagements rather than fighting it.

How Did Tracey van Marcke Build a Fractional COO Practice Without Cold Outreach?

She didn't plan to. Tracey found herself in career transition during COVID and stayed open to what came next. When three different contacts in her network said, "While you're looking, could you help us with X?" she paid attention.

"After about the third one, I thought, hmm, there's something here," she said on Fracture. "And the projects themselves were drastically different. But the common theme was this sort of leaning in - they knew me, so it wasn't starting from scratch."

The key was being clear about her vision while staying flexible about what their needs actually were. Not every project looked the same. But the underlying value - an experienced nonprofit CEO who understood what leadership actually felt like and could shoulder some of it - was consistent.

Five years later, most of her business still comes from people who know her or were referred by someone who does. She hasn't needed another approach.

What's the Right Number of Fractional Clients for a Nonprofit Consultant?

Tracey's sweet spot is three to four fractional clients - and the type of work matters as much as the number.

"In some cases it's really more of a coaching kind of role with that CEO, where there isn't a lot of hands-on producing of things," she explained. "In other cases, it's doing a lot of supporting of grant writing or grant strategy and it's much more time intensive."

Three to four fractional clients, with varying intensity across the portfolio, gives her enough breadth to stay engaged while maintaining the depth each client deserves. She uses project work to fill gaps - particularly when long-term clients are at the bottom of what she calls "the bell curve" of an engagement.

The bell curve matters. Every fractional relationship has a natural arc. It starts with organisational development, becomes more forward-facing, and eventually begins to taper. Knowing where each client sits on that curve - and having project work to bridge the transition - is how she maintains consistency without white-knuckling every contract renewal.

What Are the Biggest Red Flags in Prospective Nonprofit Consulting Clients?

Tracey's number one: a prospective client who bad-mouths a previous consultant.

"The way they spoke about a prior consultant was a very huge red flag. No, I don't want that situation myself."

Cindy's own experience drove the point home on the episode: a contact reached out after a consultant from her network was fired by a difficult client. He warned her the client was bad-mouthing the consultant. Six months later, the client did the same thing to him. The client was the problem.

Tracey's other flags include prospective clients who are unrealistic about timeline and budget - and who push back when she's honest about what's achievable. She's learned to stop hedging on those conversations. "I understand that's your budget and what you want to accomplish. I can't do it at this time." Full stop.

"Trusting your gut a little bit more along the way about what's a good fit and what isn't - that's where I've had the biggest learning opportunity." - Tracey van Marcke

How Should Fractional Consultants Manage Scope Expansion With Existing Clients?

This is an art form, and Tracey is honest that she's still refining it.

Her approach starts with a detailed proposal. She gets specific about scope - what's included, what isn't, what the timeline looks like. That scope gets built into the contract, with the flexibility to update it at renewal. When new things come up (and they always do), she uses the renewal conversation as the natural moment to reevaluate fees.

She also pays attention to when a client has underused what they contracted for. If a client has been hovering without fully engaging, she shifts to a new project rather than holding space. That flexibility keeps the relationship valuable even when the original scope didn't land the way everyone expected.

The thing she won't do again: have client staff report to her. It happened once in a long-term engagement. As the relationship became more forward-facing, she became more integrated into their structure. It eventually felt wrong.

"Although I have loved developing teams over the course of my career, it was something I didn't want to do in my business. I built it to be something I could run by myself. And so having employees within the client organisation - I ultimately felt like it wasn't fair to them."

How Do Project Engagements Turn Into Long-Term Fractional Relationships?

Tracey uses project work as a deliberate entry point. Strategic planning and HR policy work are her two most successful doorways.

On strategic planning: "It's not my favourite thing to do as a standalone. But if I know there's potential to work long-term, my sweet spot is the bridge between strategy and implementation. So I always come to it with that lens, and then I can sort of craft, well, you'll want to do this - I could do this."

On HR policy work: "An executive director who can hand off their HR policy manual - one that at one point made sense, now doesn't, and no one's following it anymore - I can absorb all of that angst and then give them back something they can check off their list. And then they're like, they don't want to let me go."

That last part is the point. When a client experiences the relief of handing something genuinely difficult to someone who absorbs it competently and gives it back clean - they find reasons to keep you around. The project becomes a retainer. The retainer becomes a relationship.

Frequently Asked Questions

How do nonprofit fractional consultants find clients without cold outreach?

The most sustainable source is your existing network. Start by telling the people who already know and trust you what you're doing. Be curious about what they're struggling with - not what you can sell them. Let the first project prove the value, and let the relationship determine what comes next. Tracey van Marcke built a five-year fractional COO practice this way.

What is a fractional COO for a nonprofit?

A fractional COO for a nonprofit is a senior operations executive who works with the organisation on a part-time retainer basis - usually for a CEO or executive director who needs a strategic operational partner but doesn't have the budget or need for a full-time role. They are external to the organisation but deeply connected to the leadership relationship, handling whatever the CEO needs off their plate: process development, HR policy, funding strategy, board support, or all of the above.

How many fractional clients should a nonprofit COO consultant have?

Three to four is a sustainable range for most fractional COO consultants. The specific number depends on what each engagement involves. A coaching-focused relationship with a CEO requires less production time than one involving active grant strategy or HR process development. Know your own capacity at the project level, not just the client count.

How do you handle it when a fractional client engagement ends?

Expect it. Every fractional relationship has a natural arc - it rises, peaks, and tapers. The time to plan for the transition is during the engagement, not after it ends. Use that tapering phase to re-engage your network, take on project work, or deepen a relationship with an existing client that has more potential. Stressing about the timing doesn't change it - and in Tracey's experience, it always works out.

What's the difference between project consulting and fractional consulting for nonprofits?

Project consulting is time-bound and deliverable-focused - you're hired to produce a strategic plan, a policy manual, a specific outcome. Fractional consulting is a retained relationship with no fixed end date; you're available on an ongoing basis to think alongside the leader and implement. Project work can be a smart entry point into a fractional relationship, particularly with organisations that are reluctant to commit to a retainer before they've experienced what you do.

Should a fractional consultant have employees or manage client staff?

This is a personal choice, but Tracey van Marcke's experience suggests caution. She had client staff reporting to her during a long-term engagement - it grew organically but eventually felt misaligned. She hadn't built her business to manage employees. It wasn't fair to the staff, and it moved her away from the model she wanted to run. Clarify early whether managing people is part of your offer - and whether you actually want it to be.

How do you use strategic planning work to get fractional clients?

Tracey uses strategic planning as a doorway with a specific framing: her expertise is in the bridge between strategy and implementation. So when she does strategic planning work, she positions herself as the person who helps develop the strategy and helps execute it. That framing sets up a natural continuation into fractional work, because implementation needs someone. Be explicit about that vision during the project, so the conversation about what's next is natural rather than a sales pitch.


Building a fractional consulting business for nonprofits doesn't require a complex system. It requires relationships, clear positioning, patience to let project work prove itself, and the discipline to say no when something doesn't fit.

Tracey van Marcke has done it for five years. The advice she gives isn't glamorous. It works.
