How AI rewrote it
Nine shifts that already changed every stage. None of them are coming; they have happened.

The shape changed
The funnel did not break. It changed shape. AI did not replace the path from stranger to customer, it rewrote what happens at each stage.
Discovery moved upstream of your website. The form is being disassembled. Velocity replaced volume as the strongest intent signal. Conversation is replacing the static page for complex offers. Outcome-based pricing restructured the close. And the checkout itself is moving to agents.

Ten shifts
None of these are coming. They have already happened. Ten shifts, each grounded in something verifiable, mapped across the five stages.
Discovery moved into the model. AI search filters visitors before they arrive, so they reach you already shortlisted. Ahrefs measured AI-referred traffic converting far higher than organic on its own site (one source, hold it lightly); Similarweb's cross-site ecommerce data is steadier at 11.4% versus 5.3%.

Visitors arrive already decided. 6sense surveyed 4,000 B2B buyers: 94% have a preferred vendor at first contact, and buy from that early favourite 77% of the time. The convincing has to happen before they land. 6sense
Personalisation went agentic. An agent reads the visitor's signals and chooses the next move with no marketer writing the rule. Mutiny's Notion build lifted product signups 60% while running 850% more tests. Mutiny
The form is being enriched away. Enrichment fills role, company, and pain from a single email, so the visible form shrinks while the data grows. Gong lifted demo-request conversions 70% by cutting fields; the benchmark is a 3 to 6% lift per field removed. Clearbit
Speed became the signal. AI scores how fast a visitor moves, not how often. SAP Concur cut time in the engaged stage from 137 days to 35, a 4x speed-up at the same volume. Demandbase
The messy middle collapses. Google's messy middle is the loop between exploring, adding options, and evaluating, narrowing down, that runs between trigger and purchase. AI compresses it: the assistant synthesises and compares inside one chat, so the consideration that used to play out across your pages now happens before anyone arrives. With consented first-party data layered onto behavioural biases, Google found personalisation can move up to 43% of people off their stated first-choice brand. Messy middle AI search First-party data
Conversation replaced the static page. Sierra's conversational agents run at 40% of the Fortune 50. For a trust-first, high-complexity offer the chat is the landing page. Sierra
Polish reads as suspicious. As AI floods the zone, signs of humanness gain value. Klaviyo found 32% of consumers trust brands less for AI content; labelling it openly made 41% feel more positive. Klaviyo Zefr
Outcome pricing reached software. HubSpot's Breeze charges $0.50 per resolved conversation and $1 per qualified lead. You pay when it works, so the buyer's 'what if it fails' objection collapses because the seller carries the risk. HubSpot
Agentic commerce reaches the checkout. AI assistants are being optimised to act on the buyer's behalf, from discovery to checkout. 'Share of prompt' is becoming the new 'share of mind', and these systems reward structured specificity over beautiful copy, so a homepage is one signal among thousands. The Universal Commerce Protocol, codeveloped with Shopify, Etsy, Wayfair, Target and Walmart, formalises machine-to-machine checkout. Share of prompt Commerce protocol
