Why pipeline concentration is a growth risk (and what to do about it)
By Baidy Barton, Founder of Tailwind Growth ·
The short answer
When a small number of clients make up most of your revenue, one phone call can wipe out your capacity plan and your cashflow. Feast or famine usually isn't bad luck. It comes from focusing 100% on delivery. You reduce the risk by keeping pipeline work going during busy periods, and by regularly stress-testing your model with one question: what happens if we lost this client?
Five buckets of hummus
I eat a lot of hummus. My daughter eats a lot of hummus. Heck, hummus is a whole family staple. I also hate going to Woolies more than once a week.
One week we had five buckets of hummus in the fridge (too many, or a new record, depending on how you look at it). But I'd rather have five buckets than one. Because that last bucket will definitely be borderline empty when I reach for it on Tuesday night. Cue a meltdown.
Your client base works the same way.
What concentration risk looks like in practice
I work with a founder who had two key clients, both on an embedded partnership model. In the same month, one client called to cut their hours by 66%, and the other cut back by 55%.
Suddenly they were scrambling, chasing new leads to fill their team's spare capacity, and managing cashflow to cover payroll.
Feast or famine isn't bad luck
It's the result of 100% focus on delivery, and not stepping back to ask "what happens if we lost this client?", even when things are going well.
It's an easy trap. When a big client is keeping you busy, pipeline work feels optional. I've been there: early in my career I was so deep in delivery for a major client that I never built the relationships with their new leadership. When the work went out to tender, I had to hustle twice as hard.
How to reduce pipeline concentration risk
Keep the pipeline moving when you're busy. Busy periods are exactly when pipeline work gets dropped, and exactly when you need it most, because the next opportunity takes months to land.
Stress-test your model. Step back regularly to poke and prod your business: which clients would hurt most to lose, how quickly could you replace them, and what's your cashflow runway if they cut back?
Build relationships beyond your main contact. Know the decision-makers, especially when leadership changes.
The goal is that when a client calls to halve their spend, it's an inconvenience, not DEFCON 1.
Frequently asked questions
What is pipeline concentration risk?
The risk that comes from relying on a small number of clients for most of your revenue, so losing or downsizing one of them has an outsized impact on capacity and cashflow.
How do I stop the feast-or-famine cycle?
Keep doing pipeline work during busy periods, track opportunities in a simple system, and regularly ask what would happen if your biggest client left.
How many clients is too few?
There's no fixed number, but if losing any single client would force you to cut staff or scramble for cashflow, your revenue is too concentrated.
