Latest / The Marketing Funnel Podcast with Fexingo: Awareness, Interest, Decision, and Action Stages / How HubSpot Turned Its Own Marketing Funnel Into a Case Study
Transcript
- Lucas: So HubSpot. By now it's basically a verb, right? You tell a marketer you're 'doing inbound,' and everyone knows you mean HubSpot's playbook. But the company itself has built one of the most deliberate marketing funnels in the software industry. And they've done it by turning their own methodology into the product. Luna: It's almost recursive. They teach you how to build a funnel, and then they build that exact funnel to sell you the tool that teaches it. Lucas: Exactly. And it started over twenty years ago, back in 2004 in Cambridge, Massachusetts. Brian Halligan and Dharmesh Shah were MIT Sloan students, and they noticed something. Traditional outbound marketing—cold calls, spammy emails, interruptive ads—was getting less and less effective. People were tuning it out. So they flipped it. Instead of chasing customers, they said, let's create content that pulls them in. That's the original 'inbound' thesis. Luna: And that thesis became a blog, and that blog became the engine for everything else. Lucas: Right. The blog was the top of the funnel. And the key move was that they didn't just write about their product—they wrote about marketing itself. How to write better emails, how to optimize a landing page, how to measure a campaign. For years, they were basically giving away their consulting playbook. Back in 2006 they even published a free e-book called 'Internet Marketing: The What, The Why, and The How.' It was essentially their course material, free. Luna: So they were building trust with a massive audience before they had a product to sell? What did they even sell back then? Lucas: They were actually a consulting agency first, and this content was their lead magnet. But pretty quickly they realized the real product should be software that automates all this. The blog, the e-books, the free tools—they were the top of the funnel, pulling in anyone who wanted to learn. Then the conversion stage was offering free trials of their marketing automation platform. And it worked. By 2012, they had over 10,000 customers and went public on the New York Stock Exchange at a valuation around nine hundred million dollars. Luna: And now they're what, a multi-billion dollar company with over two hundred thousand customers? But the funnel has evolved a lot since then, hasn't it? Lucas: Yeah, and that's the interesting part. They used to call it a funnel, but around 2018 they rebranded to the 'flywheel.' Partly because the funnel implies a one-way transaction—you get customers at the end. The flywheel is about momentum. Happy customers create referrals, which feed back into awareness. So the top of the funnel isn't just content anymore. It's your existing customers' success. Luna: And they built a whole new product around that idea. The CRM. Lucas: Yes. In 2014, HubSpot launched a free CRM. And that was a masterstroke for the middle of the funnel. Now, instead of just reading their blog, you could actually use their product for free. That CRM was the lead magnet—it captured their email, their company info, their pain points. And then the natural next step was to upgrade to the paid marketing hub, sales hub, or service hub. It's a classic freemium funnel, but HubSpot made it work because the free tier is genuinely useful. It's not a stripped-down demo. Luna: I used it myself at a small startup. We never paid a dime, but we were in their system every day. It did feel like the natural next step to start using their email tools. Lucas: That's exactly the intended behavior. And it's not just the product—their content engine is still going strong. They have one of the most popular marketing blogs on the internet, now reaching millions of readers a month. They also have free certification courses, an academy, industry reports. All that content feeds the top of the funnel. Then the free tools and the CRM are the middle. And the paid upgrades are the bottom. But the genius is how the bottom feeds back to the top. Luna: So how do they measure the success of their funnel? I mean, they're a public company, so they have to report numbers, but what are the key metrics they look at? Lucas: They report things like customer count, average revenue per customer, and net revenue retention. Net revenue retention is crucial because it shows if they're really building a flywheel. If existing customers are expanding their spend over time, that's the flywheel spinning. In recent years, they've been reporting net revenue retention in the high ninety percent range or even above a hundred percent. That means the average customer is spending more each year, which is a powerful signal for a SaaS business. Luna: And those expansion dollars aren't coming from new marketing—they're coming from the product and the ecosystem. That's the flywheel effect in practice. Lucas: Exactly. But here's a nuance. HubSpot's funnel isn't just a series of steps. It's a full ecosystem. The blog, the academy, the free tools, the CRM—they all work together to keep people in the system. And they've expanded into a full customer platform. You can run your entire marketing, sales, and service operations inside HubSpot. So once you're in, the switching costs are high. That's the moat. They've essentially built a funnel that ends in lock-in, but it feels like partnership. Luna: It's interesting because a lot of people criticize HubSpot for being expensive as you scale up. But the argument is that the cost is justified because it replaces a stack of other tools. Lucas: Right. And that's part of the decision stage. They make the comparison easy: why pay for a separate email tool, a social scheduler, a CRM, an analytics tool, when you can have it all in one? And their marketing collateral is full of these calculators and ROI templates. They're actively helping you justify the cost to your boss. That's the decision-stage content—they give you the ammunition you need to buy. Luna: So what can a small business learn from HubSpot? Because I imagine most of our listeners don't have a two-hundred-person marketing team. Lucas: Great question. The core principle is to create value before you ask for anything. HubSpot's blog was their top of funnel for years, and it worked because it was genuinely helpful. A small business can do the same—write about the problems your customers face, answer their questions, and do it consistently. You don't need to be a giant to do that. You just need to be useful. Luna: And the freemium lesson: offer something of real value for free, even if it's small. A free consultation, a free tool, a helpful checklist. It builds trust and starts the relationship. Lucas: Exactly. HubSpot's free CRM is the perfect example. It's not a lead magnet that's only good for capturing emails—it's a genuinely useful product. That's why it works. And that's the bigger lesson: the best funnels are built on generosity, not tricks. Luna: That's a good note to end on. So if you want to learn more about building a funnel that works, you know where to look. Lucas: Honestly, if today was worth a coffee to you, that's the link—buy me a coffee dot com slash fexingo. It helps us keep these conversations ad-free. Luna: And we really appreciate it. But back to the funnel—one thing I want to ask about is the risk. HubSpot depends a lot on its own content and inbound, but what happens if Google changes its search algorithm or if LinkedIn changes how it promotes content? Isn't that a risk? Lucas: It's a real risk, and HubSpot has diversified. They're not just on SEO anymore. They have a huge presence on YouTube, they run the INBOUND conference, they have a massive email list. And of course, their product itself is the ultimate moat. But you're right—relying on a single channel is dangerous. That's why they've built a multi-channel approach. For small businesses, the lesson is to not put all your eggs in one basket. Use your blog, but also build an email list, a podcast, a YouTube channel. Diversify your awareness sources. Luna: And that's a perfect transition to what they've done with their academy. That's another top of funnel asset that builds trust and authority. Lucas: Absolutely. The HubSpot Academy offers free certification courses on inbound marketing, sales, and customer service. Over a million people have taken these courses. That's millions of people who have learned the HubSpot way and see them as the authority. And when those people eventually need a marketing platform, guess which one they think of first? Luna: It's like a university funnel for a software company. Lucas: Exactly. And they've also built a huge partner ecosystem. Agencies that specialize in HubSpot implementation refer business to them. That's a massive B2B referral engine. So even if some channels decline, they've got multiple paths into the funnel. Luna: So if I'm a small business owner, what's the one takeaway from this episode? Should I go build a free course? Should I buy a HubSpot CRM? Lucas: I'd say the takeaway is to think about your funnel as a cycle, not a straight line. Don't just focus on getting new customers—think about how you can create value for them after the sale so they become advocates. HubSpot's flywheel is all about that momentum. And you can start small. Offer a free tip sheet, a free consultation, or even just a really helpful email series. The key is to be genuinely useful at every stage. Luna: And that's the kind of marketing that builds long-term trust, not just a quick sale. Lucas: Yeah. And that's what makes HubSpot's funnel a case study worth studying. It's not just about the tactics—it's about the philosophy. Give first, earn the right to ask later. That's a principle that works for any business, regardless of size.
