Marketing chases attention. Sales chases revenue. The argument between them always breaks out at the same spot in the funnel — the one spot nobody has been made to own.
Most founders I work with can describe the symptom before I’ve finished asking. Marketing’s had a good month: leads up, cost-per-lead down, dashboard green. Sales says the leads are rubbish. They’re both looking at the same pipeline and they’re both sure they’re right.
More often than not, they both are. The leads marketing is proud of and the leads sales is dismissing are frequently the same leads, seen from opposite ends of a gap that neither team has been told to mind.
So the argument isn’t really about lead quality. It’s about two words the business has never sat down and defined together. MQL and SQL get used as labels — a tag marketing sticks on a lead before sliding it across to sales. Scored 75, call it qualified, send it over. Sales picks it up, finds someone who grabbed a download six weeks ago with no intention of buying anything, and quietly stops trusting the handoff. From then on every lead gets the same shrug, the good ones included.
What changes it isn’t a better scoring model or a pep talk about working together. It’s seeing what those two words actually are.
MQL and SQL are not stages. They’re doors.
A funnel really has three zones, not five or seven stages. Intake, where strangers first become known to you. Engagement, where the people who are known decide whether they’re actually in the market. And close, where a deal becomes real. MQL and SQL aren’t points along that line. They’re the doors between the zones.
MQL is the door into engagement. Its whole job is to say “worth a conversation, don’t lose them.” The bar belongs low. A lead clearing the MQL door isn’t a promise of revenue; it’s a sign you’ve stopped leaking the people you already paid to bring in.
SQL is the door out to sales, and it’s the costly one to get wrong. A lead should earn it by behaving like a buyer — the decision-maker asking pointed, problem-shaped questions and moving with some urgency — rather than by crossing a number on a scoring sheet.
Treat them as labels and the space between the two doors vanishes from view, so no one is responsible for it. Treat them as doors and that space becomes a real room in the business: the room between “worth a conversation” and “ready to buy.” It is the most fought-over, least-owned and most expensive stretch of the whole funnel. Marketing believes its job ended at the first door. Sales believes its job starts at the second. The room in between belongs to nobody, and that is where the revenue quietly drains away.
Why “just nurture them” doesn’t fix it
The usual prescription for that middle room is a nurture sequence: drop everyone into an email track and wait for them to warm up. It mostly disappoints, because it treats every lead in the room as the same person travelling the same road at the same speed. They aren’t. Two people sitting at an identical “MQL” can be a tyre-kicker who will never buy and a serious buyer a week out from deciding. One email track can’t speak to both. It bores the first and patronises the second.
What the middle actually needs isn’t more contact. It’s reading: being able to tell the lead who’s warming up from the one who’s going quietly cold, and doing something different for each. That’s a judgement call, not an automation, and it’s the part most businesses have never built any way of doing. So it collapses back into “send another email” and “sales will chase them when there’s time.”
The most valuable stretch of your pipeline is usually the one nobody has been made responsible for.
What this means if you’re the one carrying it
If your marketing and sales people are at war over lead quality, refereeing the argument won’t help. It isn’t a personality clash and it isn’t a motivation problem. The two doors of your funnel have never been defined, agreed and handed to someone to own, so the most valuable part of your pipeline runs on luck.
I spent twenty-two years building a marketing business to just under ten million in revenue, and I watched this same argument play out inside my own walls long before I saw it in the four hundred-odd founder businesses I’ve worked with since. It was almost never about how hard anyone was trying. It was about a seam in the business that nobody had drawn a line around and put a name against.
Three questions worth sitting with:
1. If you asked your head of marketing and your head of sales to each write down, on their own, what makes a lead an SQL — would the two answers match?
2. Who, by name, owns a lead while it sits between “captured” and “ready to buy”?
3. When a lead goes quiet, does anyone notice, or does it just sit in the CRM going cold?
If those don’t have clean answers, that middle room is costing you more than any single campaign is bringing in. And it won’t be solved by marketing or by sales, because it doesn’t belong to either of them. It’s a question of how the business is built — which is the work most founder-led companies never get to, because no one owns the seam where it lives.
