B2B demand generation planning for 2027: the enterprise playbook

What changed in B2B buying going into 2027

Three shifts from 2025 and 2026 research should shape every 2027 plan. First, buyers want to do most of the work alone: Gartner found that 67% of B2B buyers prefer a rep-free experience, and 45% used AI during a recent purchase. Second, buying groups are bigger than most plans assume: Forrester reports an average of 13 internal stakeholders and 9 external participants per purchase decision, and purchases involving generative AI features have buying groups twice that size. Third, buyers still validate: Gartner also found that 69% of buyers check AI-generated insights with a sales rep, and that buyers used an average of seven information sources during a recent purchase.

Put together, your 2027 plan has to win three moments: when an AI assistant or search engine builds the first shortlist, when the buying group researches on its own, and when someone finally talks to sales to confirm what they already believe.

Step 1: set one pipeline target with sales and finance

Most annual plans start with last year’s budget and add a percentage. Start instead with the revenue target, work backwards to the qualified pipeline needed at your real win rate, and agree that number with sales and finance before any channel discussion.

1. Take the 2027 new-business revenue target from finance.
2. Divide by your trailing 12-month win rate on qualified opportunities to get the pipeline needed.
3. Split that pipeline by segment, region and product line, using last year’s deal sizes.
4. Agree what marketing sources, what it influences and what sales creates on its own.
5. Write the definitions down: what counts as a qualified lead, an opportunity and sourced pipeline.

Our pipeline gap calculator does this arithmetic in a few minutes and shows the shortfall against your current run rate.

Step 2: allocate budget by funnel stage, not by channel

Channel-first budgets lead to channel-first reporting, and nobody owns the gaps between them. Allocate by job to be done, then pick channels for each job.

These ranges are planning starting points from enterprise programs we run, not benchmarks. The right mix depends on deal size, sales cycle and how much demand already exists in your category.

Step 3: plan for the whole buying group

With 13 internal stakeholders and 9 external participants on an average decision, a plan built around one persona will reach a fraction of the people who decide. Map the roles that appear in your closed-won deals: economic buyer, technical evaluator, end users, procurement, security and the outside advisors who influence them.

• Give each role one message and one proof point it cares about.
• Target roles inside the same accounts, not separate audiences.
• Measure buying-group coverage per account: how many roles engaged before the first meeting.
• Hand sales an account view, not a list of individual leads.

Step 4: treat AI search as a channel with its own plan

Buyers are asking ChatGPT, Gemini, Copilot, Perplexity and Claude to build their shortlists. TrustRadius found that 63% of technology buyers used AI during their purchase journey and 83% shortlisted three or fewer products. If you are not in the AI answer, you may not be on the shortlist at all.

Clicks are also shrinking where AI summaries appear: Pew Research found that Google users clicked a traditional result in 8% of visits with an AI summary, against 15% without one. Plan GEO as its own workstream: answer-first pages, clear comparisons, structured data, consistent descriptions of your company across the web, and a monthly check of how AI assistants describe you.

Step 5: fix measurement before January

If January campaigns launch on broken tracking, the whole first quarter is judged on platform metrics. Use the fourth quarter to fix the plumbing.

• Forms, CRM and ad platforms connected, with offline conversions flowing back to Google, Microsoft and LinkedIn
• First-party and server-side tracking so consent and browser limits do not erase your data
• One source field per lead that survives handoff to sales
• A weekly report that shows meetings, opportunities and pipeline by program
