The real reason your GTM isn’t working — and what to do about it before you run out of runway
There’s a version of the growth story that gets told a lot.
You hire a marketing person. You set up HubSpot. You get Clay. You connect it all up, write some sequences, start pushing leads into the top of the funnel — and wait for the machine to work.
It doesn’t.
Leads come in but don’t convert. Sales blames marketing. Marketing blames sales. Everyone adds another tool to fix the problem the last tool didn’t solve. And somewhere in the middle of all that, seven months of runway quietly becomes four.
I sat down with Brendan Tolleson — CEO of RevPartners and founder of Southbound — to unpack why this keeps happening. Brendan’s built RevPartners into one of the fastest-growing HubSpot Elite partners on the planet. He’s seen this movie a hundred times.
His diagnosis is pretty simple: the problem isn’t the tools. It’s the thinking behind them.
The Friction Tax
Here’s the thing nobody tells early-stage founders about their tech stack.
Every tool you add that your team doesn’t fully use isn’t neutral. It’s a tax. On your data. On your team’s time. On your ability to make a clear decision. Brendan calls it the Friction Tax — and once you see it, you can’t unsee it.
“Less is more. If you’re a high-growth organisation, you’re going to have turnover. If you have 20-plus tools in your stack, driving 100% adoption gets really hard, really messy.” — Brendan Tolleson
The promise of every new GTM tool is the same: move faster, close more, save time. The reality is that each one requires someone to own it, train it, monitor it, and fix it when it breaks. Most startups don’t have that person. So the tool sits half-configured on a shelf, feeding garbage data into a system that was supposed to give you clarity.
The market backs this up. Only 7% of revenue leaders feel confident about hitting their growth targets — and a major driver of that is operational complexity. Technology overload — selecting the right technology stack without creating redundancy or inefficiencies — is consistently cited as one of the biggest hurdles in revenue operations.
The fix isn’t finding better tools. It’s using fewer of them, better.
Brendan’s rule: Every tool needs a named owner and a live metric attached to it. If you can’t answer both in five seconds, the tool is overhead, not infrastructure.
The $1 Trillion Elephant in the Room
Let’s talk about the real leak in most early-stage GTM systems.
It’s not awareness. It’s not positioning. It’s not even the product.
It’s that sales and marketing aren’t actually working together — and the cost of that is staggering. Misaligned sales and marketing teams cost B2B companies 10% or more of revenue per year. For a $50 million company, that represents at least $5 million in annual losses from inefficient processes, wasted content, missed opportunities, and unproductive prospecting.
Scale that down to an early-stage startup with $800K ARR and you’re still talking about $80K walking out the door. That’s a hire. That’s three months of runway.
The finger-pointing dynamic Brendan describes is universal. Marketing says the leads are good. Sales says the leads are trash. Meanwhile, close to 75% of marketing leads never convert into a sale, and up to 60–70% of B2B content is not being used by the sales team that’s supposed to be using it.
Companies with strong sales and marketing alignment achieve 20% annual growth rate. Companies with poor alignment have a 4% revenue decline. That’s a 24-point spread. On the same product. In the same market.
Here’s what Brendan says actually fixes it: data, not conversation.
“When you get the data set up properly, it’s not he said, she said. It’s objective. It’s no longer a subjective thing.”
Once you can see where leads are dropping out of your funnel — not roughly, but specifically — the argument ends. You’re no longer debating opinions. You’re solving a problem.
The Revenue Bow Tie: A Framework for Finding Your Leak
This is the model Brendan uses with every early-stage client. It sounds simple. Most founders aren’t actually doing it.
Think of your revenue funnel as a bow tie. Left side is pre-customer. Right side is post-customer. Most early-stage companies only look at the left side — and even then, they’re not looking closely enough.
Here are the five stages you need to be tracking:
1. Top of Funnel Volume Are you generating enough lead volume to even have a conversion problem? If you’ve got 20 leads a month, your close rate doesn’t matter yet. Volume is the constraint.
2. Lead → MQL (Marketing Qualified Lead) Is marketing sending the right people? Are those leads matching your ICP, or just filling a quota?
3. MQL → SQL (Sales Qualified Lead) Is sales accepting what marketing sends? If sales is regularly rejecting MQLs, you don’t have a marketing problem. You have a handoff problem — and that’s a conversation you need to have with both teams in the same room.
4. SQL → Close This is the moment of truth. Does your product actually solve a problem your buyer is feeling right now? If conversion here is low, it’s not a messaging issue — it might be a product-market fit signal you can’t afford to ignore.
5. Close → Retention Are the right customers coming through the door? Retention data will eventually tell you whether your acquisition engine is bringing in people who actually stay.
The common failure mode: Founders see a revenue problem and go straight to “we need more leads.” Usually the real drop is happening at Stage 3 — the MQL to SQL handoff. You’re not under-marketing. You’re under-aligning.
The setup Brendan recommends for early-stage founders: Don’t over-engineer it. Four pipeline stages in HubSpot or whatever CRM you’re using. Define what it means to move from one stage to the next. Give it 90 days. The data will show you exactly where your funnel is breaking.
The Hub Illusion
Here’s a tension that doesn’t get talked about enough.
If everyone is using Clay to build the same sequences, targeting the same ICPs, using the same AI-generated personalisation — what actually differentiates you?
Brendan and I spent a good chunk of the conversation on this. And his answer was uncomfortable but honest: the tool is never the moat. The strategy and story behind it are.
“The sustainable competitive advantage is really your story, your brand — and your product differentiation.”
This is why the rise of intent-based outreach matters. Not because it’s a new trick, but because it’s how you cut through a world where everyone’s inbox is being managed by AI on their behalf. Brendan’s team at RevPartners is building outbound flows based on real buyer signals — website de-anonymisation, G2 page visits, LinkedIn engagement from specific thought leaders. The message isn’t generic. It’s contextual.
The example that stuck with me: For Southbound promotions, RevPartners targeted people who had engaged with posts from Yamini Rangan and Varun Anand — and invited them specifically to hear those speakers live. Not a blast. A signal-triggered, personalised reach-out.
That’s not AI automation replacing human connection. That’s AI putting the human in a position to connect.
From System of Record to System of Action
There’s a broader shift happening in how we think about CRMs — and it’s relevant whether you’re a solo founder with 50 customers or a Series A team scaling toward 500.
For years, a CRM was a system of record. A database. You put contacts in, tracked deals, ran reports. Mostly reactive. Mostly backward-looking.
What Brendan is describing — and what the best GTM teams are actually building — is a system of action. The CRM doesn’t just store what happened. It tells you what to do next.
“The shift we’re seeing is from system of record to system of action — from reactive to proactive. How does your database not just store, but inform the next action to take?”
In practice, that means: a contact goes quiet, the system flags it. A prospect visits your pricing page, and the sequence changes. When a customer’s job changes, the record updates, and a re-engagement play fires automatically.
This is where HubSpot and Clay, used well together, become genuinely powerful. Not because they’re magic. Because when they’re set up with real intent signals and clean lifecycle data, the outreach stops feeling like spam.
Gartner predicts that 75% of the highest-growth companies will adopt a RevOps model by the end of this year — up 30% from just two years ago. The companies winning the GTM game in 2026 aren’t the ones with the most tools. They’re the ones who’ve figured out how to make those tools talk to each other in service of one thing: the right message, to the right person, at the right time.
Trust Is the Only Currency That Doesn’t Inflate
We talked a lot about AI and automation. But the thread running underneath all of it was something older and simpler.
Trust.
Brendan put it plainly: “Trust is the currency, and it’s very fragile. It can get broken very fast. People can sniff that stuff out very quickly.”
The flood of AI-generated outreach hasn’t killed prospecting — but it has raised the bar on what earns attention. Direct mail is working again. Phone calls are making a comeback. In-person events are packed. Not because the digital channel is dead, but because humans are increasingly good at filtering out what doesn’t feel real.
This is why personal brand matters so much for early-stage founders right now. Your company brand is unknown. Your product is unproven. But your perspective, your story, your point of view — those have weight. They’re yours. They can’t be replicated by a competitor who buys the same Clay subscription.
Brendan’s rule on this: pick your platform, have a real point of view, and show up consistently. Not as a broadcaster. As a person with something to say.
The irony is that the more AI floods the channel, the more premium a real human voice becomes.
One Practical Thing to Do This Week
Before you add anything to your stack. Before you hire anyone. Before you run another campaign.
Map your funnel.
Not in theory. Literally open your CRM and count the drop-off at each stage. If you don’t have stages set up yet — that’s your answer. Set up four. Give them names that match how your buyers actually move. Spend a week looking at where deals go to die.
That data will tell you more than any consultant, any new tool, or any growth hack you’ll read on LinkedIn this week.
Then fix the leak. One thing. Don’t add fuel before you’ve patched the tank.
Where to Hear More of This: Southbound, Atlanta, April 16
If this conversation sparked something for you, there’s a room being built right now where you can go deeper.
Southbound is a one-day GTM conference for revenue leaders happening April 16 at the Coca-Cola Roxy in Atlanta. This is its third year. The theme is timeless principles and timely tactics for growth — which is exactly the tension Brendan and I kept coming back to in this episode.
The speaker lineup is genuinely excellent:
Yamini Rangan — CEO, HubSpot
Varun Anand — Co-Founder, Clay
Donald Miller — CEO, StoryBrand and NYT bestselling author
Mark Roberge — Co-Founder, Stage 2 Capital and founding CRO of HubSpot
Sangram Vajre — Founder & CEO, GTM Partners
And more
What makes Southbound different from most conferences isn’t the stage. It’s the intent. Brendan designed this as a high-trust environment — not a series of sponsored keynotes, but a room where revenue leaders can actually learn something and talk to each other. Capped at 500 people. Southern hospitality. And yes, a world-class mentalist closing out the day before happy hour.
