Latest / The Marketing Funnel Podcast with Fexingo: Awareness, Interest, Decision, and Action Stages / How HubSpot Built the Inbound Marketing Funnel
Transcript
- Lucas: So we've spent four episodes looking at specific companies and how they built — or in Casper's case, blew — their marketing funnels. But I realized we haven't done the origin story. The company that basically wrote the textbook on the modern digital marketing funnel. Luna: You're talking about HubSpot. Lucas: Exactly. HubSpot didn't just use a marketing funnel — they codified it. In 2006, Brian Halligan and Dharmesh Shah published the original inbound marketing framework: Attract, Convert, Close, Delight. That became the blueprint for basically every B2B SaaS company that followed. Luna: And they built an entire company around selling that methodology. HubSpot went from zero to over 100,000 customers by 2021. But I want to ask — does that original funnel still work in 2026? Lucas: That's exactly the question. Let's start with what they got right. The Attract stage — HubSpot's play was pure content marketing. They started blogging aggressively in 2006, long before most B2B companies took blogs seriously. By 2010, they were publishing multiple posts a day, and their blog was generating millions of visitors. Luna: Right, and the content wasn't just about their product. It was educational — 'how to write a blog post,' 'SEO for beginners,' 'email marketing tips.' They were capturing people at the awareness stage who had no idea they'd eventually buy marketing software. Lucas: That's the genius. They built the funnel for free. Someone searches 'how to improve email open rates,' lands on a HubSpot blog post, reads it, maybe downloads an ebook. That's the transition from Attract to Convert — they've captured a lead. Luna: Then the Close stage — sales team follows up, demos the product, closes the deal. And Delight — post-sale support, community, continuous education. HubSpot Academy is basically a free university for marketers. Lucas: And that's where the flywheel concept came in. Around 2018, HubSpot started talking about the flywheel instead of the funnel, because they realized delighted customers become your best marketers. They refer others, they write reviews, they show up at your events. That creates a self-reinforcing loop. Luna: But here's the tension — the funnel was designed for a world where people searched for information and found blogs. Today, ai generated content is flooding search results. HubSpot's own blog faces competition from ChatGPT summaries. Does the inbound model still work? Lucas: I think the principles still work, but the tactics have to evolve. HubSpot's own data shows that their blog traffic plateaued around 2023. They've had to lean harder into video, into podcasting, into personalized email sequences — the Convert stage now requires much more sophistication. Luna: And the Close stage has gotten harder too. Buyers are more skeptical. They've been pitched by a dozen SaaS companies before they even talk to you. HubSpot's response has been to integrate deeper with CRM data — so when a lead comes in, the sales rep knows exactly what content they've consumed. Lucas: Which brings us to the Delight stage. HubSpot's retention rates are actually quite good — north of 90 percent for enterprise customers — because they keep investing in the ecosystem. The community, the certifications, the annual INBOUND conference. They make it hard to leave. Luna: But for the small business that can't afford HubSpot's full suite — the starter package is still $20 a month — the funnel can feel daunting. All that content creation, all those email sequences. It requires a lot of time and consistency. Lucas: Yeah, and that's the criticism. HubSpot's funnel works brilliantly if you have a dedicated content team. If you're a solo founder, you're looking at a massive time investment before you see any return. But I'd argue the principles scale down. You don't need a blog with 500 articles. You need one really good piece per month, distributed where your audience actually is. Luna: Speaking of audience — there's another shift. HubSpot's original funnel assumed people would come to you. Today, you have to go to them. Social platforms, Reddit, Slack communities. The Attract stage is less about SEO and more about being present in the right conversations. Lucas: Which is why HubSpot has invested heavily in social listening and community management. They have a team that monitors Reddit threads about marketing automation and jumps in with helpful answers — not sales pitches. That's still inbound, just on someone else's turf. Luna: And it works. I've seen HubSpot employees in dozens of marketing groups on LinkedIn, just answering questions. No link dropping. Just value. Then when someone asks for a recommendation, three people in the thread say 'we use HubSpot.' Lucas: That's the flywheel in action. But let's talk numbers for a second. HubSpot's customer acquisition cost, or CAC, has actually gone up over time. In 2015, they were spending about 40 cents of every dollar on sales and marketing. By 2024, that number was closer to 55 cents. The funnel isn't as efficient as it used to be. Luna: But their lifetime value, or LTV, has gone up too. Because they've added more products — CMS, operations hub, commerce hub. Customers who start with marketing software often add sales hub, then service hub. The expansion revenue is significant. Lucas: So the funnel became a product-led growth engine. The original Attract stage gets you in the door with a free CRM. Then the Convert stage is about getting you to use more features. The Close stage is when you hit a usage limit and need to upgrade. And Delight is making sure you love the product enough to expand. Luna: That's a very different funnel from 2006. The stages are the same, but the mechanics are completely different. It's less about content and more about product experience. Lucas: And I think that's the key lesson for marketers today. Don't copy HubSpot's 2010 playbook. Copy their 2026 playbook — which is constantly evolving the tactics while keeping the core philosophy: attract people with value, convert them with ease, close with empathy, and delight them into advocates. Luna: Before we wrap, I want to touch on one more thing — HubSpot's own marketing has shifted toward brand building. They ran a Super Bowl ad in 2024. That's pure awareness, at scale, for a company that built its name on inbound, not outbound. Lucas: Yeah, and that's a fascinating admission that even the king of inbound needs mass awareness. But here's the thing — that Super Bowl ad wasn't a traditional product ad. It was about 'the power of 'and'' — inclusive language, celebrating diversity. It was still brand building through values, not interruption. Luna: Which brings us back to the funnel. Awareness can come from anywhere — a blog post, a Super Bowl ad, a Reddit comment. What matters is what happens next. Do you have a path for that person to become interested, then decide, then act? Lucas: If today's episode was useful to you and you want to keep it ad-free, buy me a coffee dot com slash fexingo helps. That's literally what funds these conversations. Luna: Yeah, and we really appreciate it. Every little bit goes straight into production. Lucas: Alright, so for this episode, the concrete takeaway: HubSpot's funnel is a living framework. The stages are durable, the tactics are not. If you're building a marketing funnel today, steal their philosophy — but build your own plays. Next episode, I want to look at a company that inverted the funnel entirely. Think about it — what if the decision stage comes first? Luna: That sounds like a teaser. I'm curious. Lucas: See you next time.
