Jon Miller, who helped popularize the MQL, now compares its linear funnel to the geocentric model of the solar system. He argues it was a once-useful simplification that no longer reflects the complex, nonlinear reality of B2B buying, as it ignores the most important, untrackable parts of the journey.
Jon Miller calls measuring marketing-sourced vs. sales-sourced pipeline a "terrible KPI." He argues it’s impossible to do accurately due to the complex buyer journey. More importantly, it actively undermines the collaboration required for GTM success by creating a culture of credit-taking instead of teamwork.
Jon Miller highlights a fatal flaw in the common practice of calculating marketing budget by working backward from new ARR goals. This "reverse waterfall" model is entirely focused on net-new acquisition, which means it inherently allocates zero budget for marketing to existing customers, crippling retention and expansion efforts.
The real potential of AI in marketing lies in creating a unique journey "playlist" for each buyer, like a Spotify DJ. Instead of forcing prospects into predefined paths, AI can dynamically curate and adjust the entire experience based on individual signals, enabling true one-to-one marketing at scale.
Jon Miller notes a foundational flaw in legacy platforms like Marketo: they were built only for new business. Marketo's core customer journey model literally stops at "opportunity close," ignoring the post-sale lifecycle. This architectural choice makes effective customer marketing and expansion technically difficult to implement.
Jon Miller argues no CMO is great at all three marketing pillars: brand, product marketing, and demand gen. You get a major, a minor, and a gap. An exceptional CMO’s strength isn't being a unicorn, but having the self-awareness to identify their own gap and hire a strong leader to fill it.
Jon Miller realized his successful Marketo playbook failed at Demandbase because Marketo's powerful brand acted as a "tailwind," inflating program performance. This reveals that GTM success can be misattributed to tactics when brand is the true, unmeasured driver, creating a false positive for the playbook itself.
To counter a CFO's "gumball machine" view of marketing ROI, Jon Miller suggests asking them to detail their own recent B2B purchase journey. This personal reflection often reveals a complex, non-linear process driven by word-of-mouth, making them more open to funding hard-to-measure brand initiatives.
