A field guide to the 7 red flags I used to ignore, and what each one cost me.
Every consultant has a client story that still makes them wince. Mine usually start the same way. A great first call. A founder who "gets it." A deal that closes fast because nobody pushed back.
That speed should have been the warning.
So, here’s who I don't take anymore, and why I learned it the expensive way.
They don't want a system. They want a number by Friday.
I once onboarded someone who didn't want pipeline. He wanted a headcount he could report upward. The moment you agree to a lead number, you've stopped being a GTM partner and become a vendor he'll haggle with every month. And he will haggle.
Zero patience for the part where the system actually gets built.
Every real GTM engine has a runway before liftoff. ICP validation, messaging tests, list building, sequence iteration. I onboarded a client once who skipped straight to "so when do the calls start." Month one became a referendum on a system that hadn't been given a chance to exist yet.
Nothing to sell yet, but a full GTM stack expected anyway.
No product-market fit. No customer base to learn from. Sometimes no finished product. I've had someone at this stage want outbound, LinkedIn, positioning, all running in parallel, funded out of his own savings. You will get blamed for the thing you were never hired to fix: the product itself.
CEO, closer, content machine, and therapist. All before lunch.
Some engagements quietly expect the founder to post daily, comment on fifty threads, join every call, and somehow still run the company. That's not founder-led sales. That's founder burnout with a growth chart attached.
"Everyone is our customer" is not a strategy. It's a confession.
If a founder can't tell you who he loses deals to, or who his best customer actually looks like, you are not being hired to execute a GTM motion. You are being hired to have an opinion he will overrule in week three.
Zero to a million in two months, because apparently we own a magic wand.
I once had a client convinced that GTM consultants keep a secret lever somewhere. Pull it, revenue appears. When the timeline is fantasy, the retrospective is always the same: it must be your fault, because the plan was flawless.
Weeks of positioning work, collapsed into "how many calls happened this week."
You can build the sharpest ICP, the cleanest messaging, a sequence that actually converts, and it still gets flattened into one question every Friday. The system stops mattering. Only the leaderboard does.
And the one I say out loud on every discovery call now
We are not your SDR team. We never will be.
We build the system. We don't sit in a chair and dial all day. If the expectation is a warm body doing outreach at agency day rates, that's a different vendor, and a different conversation.
Every one of these clients looked fine on the first call. That's the actual lesson here, not the checklist. The people worth working with reveal themselves in what they ask for in week one, not in how well they pitch themselves in the first thirty minutes.
So here's the real question I've started asking before any proposal goes out.
What is this founder optimizing for: a system, or a number he can screenshot?
