Elias St. Elmo Lewis sketched the original purchase funnel in 1898. Awareness, Interest, Desire, Action — four clean stages that turned strangers into customers. For over a century, marketers treated it like gravity: invisible, universal, and non-negotiable. But something has changed. Buyers today don't fall neatly through a tube. They research on TikTok, read a Reddit thread at midnight, watch a YouTube teardown, ignore your retargeting ads for three weeks, then convert through a friend's DM. The funnel didn't break. It became obsolete.
What the Funnel Got Right
Before dismantling something, it's worth understanding why it worked. The linear funnel succeeded because the information environment was linear. A customer saw a newspaper ad, walked into a store, spoke to a salesperson, and bought — or didn't. Brands controlled nearly every touchpoint. The funnel was less a description of customer psychology and more a map of media access. When you own the roads, you can predict the route.
It also gave marketing teams a shared vocabulary. Top-of-funnel, mid-funnel, conversion — these terms aligned budgets, KPIs, and creative briefs across entire organizations. Even if imperfect, a shared model is powerful. That's worth preserving in whatever replaces it.
Why It No Longer Maps to Reality
Modern buyers operate in a high-information, peer-influenced, always-on environment. Consider what McKinsey identified as the "messy middle" — the chaotic space between a trigger event and a purchase decision where consumers loop endlessly between exploration and evaluation. A person becomes aware of your product, explores alternatives, evaluates yours again, gets distracted by a competitor's influencer campaign, comes back through organic search, and finally buys — three months later. No stage was skipped. All of them repeated.
Three specific shifts killed the linear model:
- Peer trust outranks brand trust. A 2023 Edelman study found that 63% of consumers trust what other people say about a brand more than what the brand says about itself. The funnel assumes the brand narrates the journey. Peers do that now.
- Discovery is decentralized. In 2024, 40% of Gen Z uses TikTok or Instagram as their primary search engine, according to Adobe. Awareness doesn't start at your ad. It starts at a comment section you've never seen.
- Post-purchase is pre-purchase for someone else. Unboxing videos, review posts, and community discussions mean your existing customers are actively creating awareness content. The bottom of your funnel feeds the top of someone else's journey.
What to Build Instead
Replacing the funnel doesn't mean abandoning structure. It means adopting a model that reflects how people actually buy. Two frameworks worth adopting — or blending:
The Flywheel
HubSpot's flywheel replaced the funnel with a circular model: Attract, Engage, Delight. Customers who are delighted become advocates who attract new customers — eliminating the artificial "end" of the funnel. The energy you put in compounds. Friction anywhere in the loop slows the entire wheel. This model forces organizations to care about retention and referral as much as acquisition, which is where most revenue actually lives.
The Orbit Model
Originally designed for developer communities, the Orbit model maps relationships by gravity (how much someone loves your product) and reach (their influence). People at different orbits — casual fans to evangelists — are nurtured differently, not pushed toward a single conversion gate. This is especially useful for brands where community and content drive sales more than paid acquisition.
Practical Steps to Make the Shift
You don't need to rip out your CRM or rebrand your entire go-to-market. Start with three adjustments:
- Audit your touchpoints by channel, not by stage. Find out where people actually first encounter your brand — most companies are surprised to find it's not where they spend the most budget.
- Measure momentum, not just conversion. Track NPS, community engagement, referral rate, and content shares alongside MQL and close rate. These are the leading indicators the funnel ignores.
- Invest in post-purchase content. Onboarding guides, tutorial videos, and community spaces don't just reduce churn — they produce the peer content that drives the next buyer's awareness.
The funnel isn't broken because someone made a mistake. It's outdated because the world it was designed to describe no longer exists. Today's most effective marketing strategies treat buying less like a descent through stages and more like a gravitational pull — built from trust, sustained by community, and amplified by every customer who sticks around long enough to become a promoter. That's not a funnel. That's a growth engine.
