Demand Generation vs Lead Generation: What 6sense Says About First Contact
On this page
B2B buyers now make first contact with a seller 61% of the way through their buying journey, according to 6sense's 2025 survey of more than 4,000 buyers. By that point, 94% have already ranked their shortlist in order of preference. That is the demand generation vs lead generation argument settled in two numbers. Lead generation records a decision. Demand generation is where the decision gets made.
Key takeaways
- Buyers reach out late and with a favourite already chosen. 6sense's 2025 Buyer Experience Report puts first seller contact at 61% of the journey, down from about 69% in 2023 and 2024. And 94% of buyers had ranked their shortlist before that contact.
- The early favourite usually wins, though less often than before. The vendor ranked first before sellers were involved won 77% of the time in 2025, against 83% in prior years, per the same 6sense report.
- Gartner's buyer research points the same direction by a different route. In a 632-buyer Gartner survey fielded in August and September 2024, 61% of B2B buyers said they prefer an overall rep-free buying experience.
- Both studies measure what buyers say, not what buyers did. "61% through the journey" is a self-reported estimate from buyers spending at least $25,000, in a study published by a company that sells intent data to demand generation teams.
Demand generation vs lead generation, defined by timing
Demand generation creates and shapes a buyer's preference before that buyer is ready to talk to anyone. Lead generation captures the contact details of a buyer who is already looking, so sales can follow up. The difference is not channel or budget line. It is where in the buying journey each one acts.
Most arguments about the two terms go wrong because they treat them as rival tactics. Gated ebooks get filed under lead gen, podcasts under demand gen, and the debate turns into a fight about which content formats deserve money.
That framing misses the useful question. A buyer's journey has a point where they first raise their hand. Everything before that point is invisible to your CRM. Everything after it is lead management. Demand generation is the work you do before the hand goes up. Lead generation is the work of catching the hand.
Framed this way, the question stops being philosophical. If the hand goes up early, lead capture has most of the journey left to influence. If it goes up late, the decision is largely made by the time you get a name. So the real question is empirical: when do B2B buyers first contact you? That is what 6sense's buyer research tries to measure.
What the 6sense buyer experience report found in 2025
6sense has run its Buyer Experience Report for several years. The 2025 edition, published on 12 November 2025, is framed around how AI is and is not changing B2B buying journeys. The headline finding is that first contact is happening earlier than it used to, though still well past the halfway point.
First contact moved from 69% to 61%
The report measures what it calls the point of first contact, or POFC. In 2023 and 2024, buyers placed it at about 69% of the way through their journey. In 2025, the figure fell to 61%. 6sense describes the balance between independent research and seller engagement as having shifted from roughly 70/30 to 60/40.
6sense attributes part of the shift to two pressures. In the report, 58% of buyers said they engaged sellers sooner than they otherwise would have to get answers about how AI was implemented in a product. 62% said economic uncertainty made them engage earlier.
The shortlist is ranked before you meet
The more consequential number sits beside the timing one. 94% of buyers said they ranked their shortlist by preference before engaging sellers. The favourite at that stage went on to win 77% of the time, down from 83% in earlier years.
Buyers evaluated an average of 5.1 vendors in 2025, up from 4.5. The vendor that won came from the buyer's day-one shortlist 95% of the time, up from 85%. So buyers are looking at more options while the eventual winner is more likely to have been known from the start.
Buyers initiated 79% of first engagements in 2025, compared with 82% in prior years, per the report. That matters for the lead generation side of this debate. Most first contact is inbound. The buyer finds you, fills in the form or books the call, and arrives with a ranking already in mind.
My read is that this is the strongest argument for keeping lead capture clean and fast rather than cutting it. The buyer who chose you is about to hand you their name. Losing them to a slow follow-up or a hostile form is losing a deal the demand work already won. That is a separate cost from the one examined in the economics of gating content behind forms, which is about capture too early, not too late.
How 6sense measured the B2B buyer journey
The numbers above get quoted constantly, usually without the conditions attached. The conditions change what the numbers can support.
| Study | Sample | Who qualified | What it measures |
|---|---|---|---|
| 6sense Buyer Experience Report 2025 | 3,744 in the main survey plus 766 in a supplemental survey, 4,510 total | Recent B2B buyers with at least $25,000 of purchase spend in the past 2 years. | Self-reported timing, shortlist behaviour, vendor outcomes. |
| 6sense Buyer Experience Report 2024 | 2,509 recent B2B buyers | Not stated on the public page. | Same core measures, partly different question wording. |
| Gartner sales survey, 2024 wave | 632 B2B buyers, fielded August to September 2024 | Not stated in public coverage. | Stated preference for rep-free buying, channel use by task. |
| Gartner sales survey, 2025 wave | 646 B2B buyers, fielded August to September 2025 | Not stated in public coverage. | Stated preference for rep-free buying, AI use in a recent purchase. |
6sense samples are from its report pages and a RevCity post by 6sense staff, November 2025. Gartner samples are from the June 2025 Gartner press release and Distribution Strategy Group's March 2026 report. Neither firm publishes full questionnaires or weighting on its public pages.
Who was asked
Every respondent in the 2025 6sense study had spent at least $25,000 on a purchase in the previous two years. The median purchase fell between $200,000 and $300,000. That is a mid-market and enterprise sample. It tells you little about a $40 per seat tool bought on a credit card, where there may be no seller to contact at all.
The sample is also made of buyers who completed a purchase. Journeys that stalled, or ended in a decision to do nothing, are not in the data. If early seller contact makes a stalled deal more likely to revive, this design cannot see it.
The report defines the point of first contact as the respondent's stated percentage through the buying journey when sellers were first engaged. Nobody timed it. A buyer was asked, after the fact, to place a moment on a scale whose start point they defined for themselves.
That makes the figure a perception measure. It is useful for comparing years, if the question stays the same. It is weak as an absolute. One buyer's journey starts when a problem is first noticed. Another's starts when a budget is approved.
There is a useful cross-check in the report's own numbers. 6sense says first contact now happens roughly 6 to 7 weeks sooner. Our arithmetic, not 6sense's: 69% of the 2024 average cycle of 11.3 months is about 7.8 months, and 61% of the 2025 cycle of 10.1 months is about 6.2 months. That gap is about 7 weeks. Roughly half of it comes from the shorter cycle, not from earlier contact.
Who paid for it
6sense sells account intelligence and intent data, products built to help marketing and sales teams find buyers during the invisible research phase. A finding that most of the journey happens before contact is a finding that supports the category 6sense sells into. A RevCity post by 6sense staff lists 2X, MarketOne, LeadFabric and Green Hat as research partners.
None of that makes the data wrong. It does mean the questions were designed by people with a view, and the numbers should be held to a higher bar of corroboration. Two small inconsistencies are worth noting. The press release says the preferred vendor "still wins 80% of deals" while the report says 77%. The report says first contact "dropped 9 percentage points" when 69 to 61 is 8. Both look like rounding. Both are the kind of thing a methodology section should resolve.
What Gartner's buyer research adds, and where it disagrees
Gartner is the natural comparison because it studies the same buyers from the sales side. Its research does not measure point of first contact directly. It measures preference and time allocation, which is a different lens on the same question.
The rep-free preference is rising
Gartner's June 2025 press release reported that 61% of B2B buyers prefer an overall rep-free buying experience. It was based on a survey of 632 buyers in August and September 2024. Buyers favoured digital self-service for general information. They still sought sellers for contextual judgement, such as whether an offering fits their company. The same release reported that 73% of buyers actively avoid suppliers who send irrelevant outreach.
A 2025 wave of 646 buyers put the rep-free preference at 67%, with 45% reporting AI use during a recent purchase. Sellers "can't rely on static collateral to carry influence in those moments," said Gartner senior principal analyst Alyssa Cruz. That coverage comes from Distribution Strategy Group rather than Gartner's own release, so treat it as Tier 2 until the release is checked.
The most repeated Gartner statistic in this debate is that buyers spend 17% of their buying time meeting potential suppliers. It was being reported as early as August 2018, attributed to Gartner, with the note that the 17% is shared across all suppliers. With 3 suppliers in a deal, each gets just over 5%. The same coverage reported 27% of buying time spent researching independently online and 18% offline.
That figure predates generative AI search, the post-2022 budget squeeze and every 6sense wave cited above. It still circulates as current. I would not put it in a board deck without the year next to it.
The two sources agree on direction: buyers do most of the work without you. They diverge on trend. 6sense says first contact moved earlier in 2025. Gartner says the preference for no rep at all rose between its 2024 and 2025 waves. Both can be true. Buyers may contact sellers sooner to get specific answers, about AI implementation for example, while wishing they did not have to. The extended version of that research phase, now increasingly run through AI assistants, is examined in how the AI shortlist forms before a buyer ever calls.
What the data means for demand gen vs lead gen budgets
If you accept the direction of both studies, the practical consequence is a shift in what each function is for. It is not a choice of one over the other.
| Question | Demand generation | Lead generation |
|---|---|---|
| Where it acts in the journey | The first 61%, before any contact | The point of first contact and after. |
| What it influences | Whether you make the shortlist, and your rank on it. | Whether a buyer who ranked you reaches sales cleanly. |
| What 6sense data says it is worth | The early favourite won 77% of 2025 deals. | Buyers initiated 79% of contact, so capture is mostly inbound. |
| Metric that fits | Share of shortlists, self-reported attribution, branded search. | Speed to response, form completion, meeting held rate. |
| Where lead generation wins | Deals without a ranked shortlist. The 6% of buyers who had not ranked vendors before contact gave the first vendor they spoke to a 57% win rate, so early outreach still moves those deals. | |
Lead generation owns the last 39%, and a minority of open deals
Lead generation is not obsolete in this picture. It has a narrower and clearer job. It catches buyers who already chose you and gets them to a seller without friction. It also matters in the small group of deals where no favourite exists yet.
What lead generation cannot do, on this evidence, is create preference. A form fill at 61% of the journey is mostly a buyer announcing a decision already in progress. Scoring it as marketing "generating" demand misattributes the work. The MQL is the wrong scoreboard for demand generation, and I would stop reporting it as one.
The 6sense numbers put the real contest earlier. A vendor that is not on the day-one list almost never wins, since the winner came from that list 95% of the time in 2025. Being ranked first matters more again. That is a reach and memory problem. It is solved by being known for a specific problem before the buyer starts looking, through content buyers can find, comparison material they trust, and people who already recommend you.
How that budget split has moved in practice is covered in what Gartner's CMO spend data shows about budget shifts. The point here is narrower. If your marketing plan is mostly capture, you are paying to record decisions other vendors' demand work is shaping.
Where this argument is weakest
The case above rests on survey data with known problems. Here is where it could be wrong.
Recall is a poor instrument for timing
Asking buyers to place first contact on a percentage scale, after a purchase that took around 10 months, invites hindsight. People who end up buying from their favourite may remember having had a favourite earlier than they did. That bias would inflate both the 94% ranked-shortlist figure and the 77% favourite-wins figure. No public 6sense material tests for it.
The finding suits the publisher
A vendor of intent data reporting that intent forms in an invisible phase is a vendor reporting evidence for its own product. Gartner sells advisory work to sales leaders and has its own reasons to frame buyers as hard to reach. Neither motive invalidates the data. Both mean the most important corroboration would come from transaction records, not surveys, and none is public.
The 95:5 view says most buyers are not in a journey at all
Research associated with John Dawes of the Ehrenberg-Bass Institute was published through the LinkedIn-backed B2B Institute. It argues that only about 5% of B2B buyers are in market in a given quarter. The reasoning, as the Ehrenberg-Bass Institute summarises it, is that firms switch providers such as banks roughly once every 5 years. That is an estimate built from switching rates, not a measured share.
If that view is right, the 61% figure describes a small minority of companies at any one time. Demand generation's job is then even earlier than 6sense implies: being remembered by the 95% who are not buying yet. It strengthens the case for demand generation, but it weakens any attempt to time spend around the 6sense curve.
The $25,000 floor excludes product-led tools, where the first contact may be a free signup and the seller may never appear. For those businesses, the lead is the product account. The demand gen vs lead gen distinction blurs, and the 6sense numbers do not apply.
How to measure demand generation without a form fill
If preference forms before contact, the measurement problem follows directly. The work that matters most leaves the fewest traces. Three methods hold up better than MQL counts, and none needs new software.
First, ask. Add one open question to every inbound form or first call: how did you hear about us? Self-reported answers are messy, and they still capture podcasts, peers and AI assistants that no tracking pixel sees. The wider measurement case is made in the piece on attribution and dark discovery.
Second, track whether you were on the shortlist in deals you lost. Your sales team can ask at close. A loss where you were ranked second is a different problem from a loss where you were never named.
Third, watch branded search and direct traffic over quarters, not weeks. They are lagging and noisy. They are also the closest public proxy for whether more buyers know your name before they start looking. Survey data like the studies above deserves the same scepticism you would apply to vendor ROI surveys and their methodology gaps.
Frequently asked questions
What is the difference between demand generation and lead generation?
Demand generation builds awareness and preference before a buyer is actively looking, so your company is on the shortlist when a need appears. Lead generation captures contact details from buyers who are already looking, so sales can follow up. The clearest way to separate them is timing: demand generation acts before first contact, and lead generation acts at or after it.
When do B2B buyers first contact a vendor?
According to 6sense's 2025 Buyer Experience Report, buyers first engage a seller about 61% of the way through their buying journey, down from about 69% in 2023 and 2024. Buyers initiated 79% of those first contacts. The figure is self-reported by buyers who spent at least $25,000, so treat it as a perception measure rather than a timed observation.
Is the 6sense buyer experience report reliable?
It is large and repeated across years, which makes trend comparisons useful. Its limits are that timing is self-reported after the purchase, the sample covers only completed purchases of $25,000 or more, and 6sense sells products that benefit from its conclusions. Use it for direction and year-on-year change, and avoid quoting its percentages as precise facts about your own market.
Do B2B buyers prefer to buy without a sales rep?
Many say so. Gartner reported that 61% of B2B buyers preferred an overall rep-free experience in a 632-buyer survey from 2024, and a 2025 wave of 646 buyers put the figure at 67%. Buyers still seek sellers for judgement calls, such as whether a product fits their company, so preference for self-service does not mean sellers are unnecessary.
Should B2B companies stop doing lead generation?
No. The buyer data narrows lead generation's job rather than removing it. Buyers initiated 79% of first contacts in the 6sense 2025 study, so fast, clean capture still decides whether a buyer who already favours you reaches sales. What the data argues against is counting form fills as proof that marketing created the demand behind them.
How do you measure demand generation?
Use signals that exist before a form fill. Ask every inbound buyer how they heard about you, record whether you were on the shortlist in deals you lost, and track branded search and direct traffic over quarters. None is precise on its own. Together they show whether more buyers know your name before they start looking, which is the outcome demand generation exists to produce.
Where to start
Pull your last 20 closed deals, won and lost, and ask one question of each. Was this buyer's first contact inbound, and had they already ranked us? If most wins came from buyers who arrived with you ranked first, your pipeline depends on demand work you are probably not measuring, and the MQL report is crediting the wrong team.
Then add the "how did you hear about us" field this week, as free text, not a dropdown. In a quarter you will have the first piece of your own data on this question, which is worth more than any vendor survey, including the two this post relies on.
