Gen Z B2B buyers are now the decision-makers. Your marketing has not caught up
Updated August 2026. By Remy Beaumont
Gen Z B2B buyers are no longer a future trend. Together with millennials they now make up 71% of B2B buyers, up from 64% in 2022, according to Forrester. The people approving your six figure contracts grew up on TikTok, research vendors in group chats, and treat a cold call as a red flag. Most B2B marketing is still built for a buyer who retired from the committee years ago.
Key takeaways
Millennials and Gen Z make up 71% of B2B buyers, and roughly two thirds of buyers on deals worth over $1 million come from these two cohorts (Forrester).
67% of B2B buyers now prefer a rep-free experience (Gartner, March 2026), and Gen Z buyers are 35% more likely than any other generation to want a fully self-serve journey (TrustRadius).
Younger buyers are harder to please: 90% report dissatisfaction with vendors in at least one area, against 71% of older buyers (Forrester).
More than 50% of younger buyers rely on external sources, including social media and their own networks, to make buying decisions, and almost a third bring 10 or more people from outside their organisation into the process (Forrester).
The winners are not adding a TikTok account to an old playbook. They are rebuilding around brand memory, ungated proof and founder visibility before the buying window opens.
Why does this matter now?
Because the handover is finished. This is not a demographic forecast, it is the current composition of the buying committee. Forrester's Buyers' Journey Survey shows younger cohorts already dominate large and complex transactions valued over $1 million, the deals where B2B marketers assume grey haired procurement still rules.
For a startup launching this year, that means the first impression of your company is usually formed with no salesperson in the room. If your launch strategy is a press release, a gated PDF and an SDR sequence, you are optimising for a buyer who no longer holds the budget.
What the research shows
Three named datasets tell the story.
Forrester: millennials and Gen Z are 71% of B2B buyers. 90% of these younger buyers report vendor dissatisfaction in at least one area. They also widen the committee, with almost one third bringing 10 or more outside voices into a decision.
Gartner: 67% of B2B buyers prefer a rep-free experience, up from 61% in its 2025 survey. Gartner also warns that self-serve purchases carry higher purchase regret, which is the trap for vendors who read "rep-free" as "effort-free".
TrustRadius: virtually 100% of buyers want to self-serve all or part of the journey, and millennial buyers get 57% of the way through the process before they will engage a rep.
Do Gen Z buyers actually buy differently, or just research differently?
Both, and the second drives the first. A buyer who self-serves 57% of the journey has formed a shortlist, a price expectation and an opinion of your brand before your CRM knows they exist. The evaluation has moved into channels you do not control: communities, group chats, review platforms, creator content and AI assistants.
This is consumer psychology applied to procurement. The same person who checks TikTok reviews before buying trainers checks peer reviews, Reddit threads and founder profiles before recommending a vendor. The purchase is bigger. The mental shortcut is identical.
Why does the old playbook fail with this cohort?
Because it was designed to interrupt a rational evaluator, and this buyer is neither interruptible nor, in the classical sense, rational. Three specific failures stand out.
Gating kills discovery. A form is a paywall priced in trust. Cognism moved to a roughly 80% ungated content model precisely because consumed content compounds into direct demo requests with real intent, rather than passing cold form-fills to sales.
Whitepapers are not memory. Gong bet its category leadership on organic LinkedIn, ditching long-form gated assets for short ungated content because millennials were taking over decision-making. Its documented sprint produced 85% page follower growth in 30 days.
You are marketing to the 5% and ignoring the 95%. Ehrenberg-Bass research for the LinkedIn B2B Institute shows up to 95% of buyers are not in market at any given time. Lead-capture marketing rents attention from the tiny in-market slice. Brand marketing builds memory in the rest, which is where younger buyers form their shortlists long before a trigger event.
The Ignita insight: stop marketing to the committee, market to the screenshot
Here is the conclusion competitors keep missing. Everyone reads the buying committee data and concludes they need more personas and more ABM tiers. The opposite is true. When almost a third of younger buyers pull 10 or more outsiders into a decision, the committee is no longer a fixed list you can map. It is a loose network that shares screenshots.
So the unit of B2B marketing is no longer the campaign or the persona. It is the shareable artefact: the pricing page that needs no call, the founder post that gets forwarded, the launch story specific enough to survive being pasted into a group chat with no context. If a piece of your marketing cannot be screenshotted and defended by a 28 year old champion in a Slack channel you will never see, it is not marketing to this generation at all.
What founders and marketers should do
Ungate your best thinking. Follow the Cognism logic: let the strongest 80% of content travel free and keep gates only where intent is already proven.
Make the founder the trust asset. Younger buyers trust people over logos. A consistent founder presence on LinkedIn or short-form video is your cheapest credibility channel.
Publish real pricing and proof. A rep-free preference of 67% means your website must close the questions a rep used to answer: pricing, integrations, security, honest limits.
Build for the screenshot. Audit every asset with one question: would a champion forward this to a sceptical colleague? Rewrite anything that fails.
Fund brand memory before demand capture. The 95:5 rule means most of your future revenue is not in market today. Allocate real budget to being remembered, not just retargeted.
Reduce regret, do not just remove reps. Gartner's regret data shows self-serve buyers still need guidance. Replace the rep with decision tools, comparison content and honest fit guidance.
FAQ
What share of B2B buyers are Gen Z and millennials? According to Forrester, millennials and Gen Z make up 71% of B2B buyers, up from 64% in 2022, and around two thirds of buyers on deals over $1 million.
Do younger B2B buyers really avoid sales reps? Largely, yes. Gartner's March 2026 survey found 67% of B2B buyers prefer a rep-free experience, and TrustRadius found Gen Z buyers are 35% more likely than any other generation to want a fully self-serve journey.
Are Gen Z B2B buyers less loyal to vendors? They are harder to satisfy. Forrester found 90% of younger buyers report dissatisfaction with vendors in at least one area, compared with 71% of older buyers, which raises churn risk for vendors who win the deal but neglect the experience.
Does this mean outbound sales is dead? No. It means outbound arrives later and must add value to a decision already in progress. Millennial buyers are 57% of the way through the process before engaging a rep, so outbound that repeats the website loses.
How should a startup launch change for younger buyers? Lead with proof and personality rather than press releases. Ungate content, publish pricing, put the founder forward, and design assets that spread through communities and group chats where this cohort actually researches.
Is brand marketing measurable enough to justify this? The Ehrenberg-Bass 95:5 research is the strongest argument: up to 95% of your category is not in market at any time, so demand capture alone structurally caps growth. Brand investment is how you enter shortlists before the buying window opens.
