TL;DR
- Non-selling activities consume two-thirds of the average sales team's time. For founders who sell part-time, the ratio is worse (McKinsey)
- It takes 12+ touches to reach a prospect, and callback rates sit below 1%. Companies with optimized sales development convert leads at 40% - without it, less than 5% (Gartner)
- 73% of B2B buyers avoid suppliers who send irrelevant outreach (Gartner). Yet research is the first thing founders cut when time runs short
- The 70% Problem is the cause. Pipeline Leakage is the effect. The product solves both
A Few Weeks Ago, I Wrote About the 70% Problem
Professionals who sell alongside their core work - founders, consultants, executives - spend the vast majority of their "selling" time on activities that aren't selling. Research, writing, follow-ups, scheduling. McKinsey found that the average sales rep spends only about 16% of their day in front of customers. In top-performing organizations, that number reaches 40-50%. The gap isn't talent. It's how much non-selling work gets in the way.
That resonated with a lot of people. But there was a response I kept hearing in conversations afterward that the post didn't address:
'I don't even do that stuff.'
Not 'I spend too much time on it.' Not 'it's frustrating.' Just... 'I don't do it.' No systematic research. No follow-up cadence. No qualification framework. They take meetings when they come, send outreach when they remember, and follow up when they have a window.
This isn't laziness. It's rational triage. When you have a client deliverable due Thursday and a prospect you met at a conference last week, the deliverable wins every time. The prospect email doesn't get written. The follow-up from two weeks ago doesn't get sent. The lead that responded warmly last month doesn't hear from you again.
That's Pipeline Leakage. And the data says it's the norm, not the exception.
The Follow-Up Gap
Gartner's research shows it takes more than 12 touches to reach an individual prospect. Callback rates sit below 1%.
Those numbers assume someone is actually doing the touching. For a full-time SDR, persistence is the job. For a founder who sells 10 hours a week between client work, touch number 4 doesn't happen because a deliverable deadline moved up and the selling window closed.
The conversion gap here is massive. Companies with optimized sales development functions convert leads at 40%. Organizations that pass leads directly to quota-carrying reps without that function convert at less than 5% - an 8x difference.
What creates that gap? Consistent execution. The research before the call. The follow-up after it. The second and third touch when the first one didn't land. It's not one thing - it's all of them, done reliably, every time.
McKinsey found that non-selling activities consume two-thirds of the average sales team's time. For a full-time seller, that's a productivity drag. For a founder juggling five roles, it's the reason the pipeline goes quiet for two weeks every time a client project heats up.
The Qualification Gap
Follow-ups aren't the only casualty. The research that separates good leads from bad leads doesn't happen either.
HBR reported on a technology company that started rigorously disqualifying prospects after initial discovery - over 50% of leads were filtered out. The result? Win rates increased by 50%. Deal sizes grew by 30%. Revenue jumped 40% in the first year.
That's counterintuitive until you think about where the time goes. Without qualification, a founder takes a demo call with someone who was never going to buy. They spend 30 minutes on discovery, 30 minutes on the pitch, an hour on follow-up materials - and the deal was dead before it started because nobody asked the qualifying questions upfront.
HBR's research confirms the pattern: the quality of a sales interaction accounts for 25% to more than half of the purchasing decision in B2B. One company saw a 17% revenue increase when it pushed reps to do more calls per day - but then a 24% increase when it shifted focus to reaching decision-makers specifically. Effectiveness compounded where efficiency plateaued.
The time-strapped founder isn't just losing deals. They're wasting the few selling hours they have on the wrong ones.
The Personalization Gap
When research doesn't happen, outreach goes out generic. And generic outreach has a measurable cost.
73% of B2B buyers actively avoid suppliers who send irrelevant or poorly timed outreach. Not irrelevant spam from strangers - any outreach that doesn't demonstrate you've done your homework. One bad message to a warm referral can undo months of relationship building.
The data on the other side is just as stark. McKinsey found that one B2B company using AI-driven personalization saw 40% higher conversion rates and 30% faster lead execution. Winning B2B companies disproportionately use hyper-personalization in their outreach - not because it's trendy, but because generic alternatives underperform by a wide margin.
For a founder juggling five roles, the research step is the first thing cut. The 40 minutes it takes to properly research one prospect is 40 minutes they don't have. So the outreach goes out generic, the response rate drops, and the pipeline gets thinner.
The 70% Problem Is the Cause. Pipeline Leakage Is the Effect
A few weeks ago, I framed the problem as time: professionals who sell lose most of their selling time to non-selling activities. That's true, and it resonates.
But the deeper problem is what happens when the time pressure gets too high: the work stops happening entirely. Follow-ups stop. Research gets skipped. Qualification doesn't happen.
The result is pipeline that was never built. Revenue that never materialized. Not lost to a competitor - lost to an overflowing inbox and a calendar that doesn't have room.
McKinsey estimates that a modest 10-20% improvement in win rates translates to 4-12% topline growth. And leading B2B companies have already offloaded up to 50% of non-selling tasks, opening 20% more capacity for actual selling. The opportunity isn't doing the work faster. It's doing the work at all - consistently, for every lead, regardless of what else is on the calendar.
The Question This Raises
If you're a professional who sells, you already know which category you fall into on any given week:
- Some weeks you do the work. You research prospects, write personalized outreach, follow up on time. And it takes all your selling hours.
- Other weeks, you don't. Client work wins, the pipeline goes quiet, and leads go cold.
Both weeks have the same problem. In one, you're drowning in the work. In the other, you're losing revenue because the work isn't happening.
The answer isn't more discipline or better time management. It's a system that does the work whether you're available or not - that follows up on Day 3, Day 7, and Day 14 because it's Tuesday, not because you had a gap between client calls. That researches every prospect before the first message goes out, because it doesn't have a client deliverable competing for its attention.
The 70% Problem is about getting your time back. Pipeline Leakage is about building pipeline that wouldn't exist without a system doing the work for you.
Either way, the answer is the same. But the urgency is different.
