People-Based Marketing in B2B: Why Individual-Level Targeting Is Replacing ABM
People-based marketing targets specific individuals — not accounts or demographics. Learn how B2B teams apply people-based targeting to reach buying group members.
People-based marketing targets specific individuals using deterministic identity matching rather than probabilistic audience segments. Originally a consumer ad concept popularized by Facebook, it's now the foundation of modern B2B targeting at the contact level.
This guide explains what people-based marketing is, where it came from, how it applies to B2B, how it differs from account-based marketing, and why more teams are adopting it. The first half is education; the second half covers practical implementation and how contact-level platforms make it work.
What Is People-Based Marketing?
People-based marketing (PBM) is an approach that targets specific individuals using deterministic identity matching rather than probabilistic audience segments. Instead of guessing who might be in your audience based on demographics, firmographics, or cookie-based signals, you upload a list of known contacts — email addresses, for example — and the platform matches those identities to user profiles across ad networks. You reach the exact people you intend to reach.
Originally a consumer advertising concept, people-based marketing has become the foundation of modern B2B targeting. In B2B, the same principle applies: you identify the named decision-makers and influencers within your target accounts, and you serve them personalized messaging across channels. The targeting unit shifts from "account" or "audience segment" to "individual person." That shift changes how you run ads, measure engagement, and hand off to sales.

Practitioners often use the terms people-based marketing, contact-based marketing, and contact level marketing interchangeably. They describe the same core idea: target the people who make and influence the decision, not just the company. For more on the contact-level framing, see our guide on what is contact-based marketing.
The Consumer Origin Story
Facebook popularized people-based marketing in the consumer advertising world. The mechanism was simple: advertisers uploaded their customer email list, Facebook matched those emails to personal profiles on its platform, and ads were served to those exact individuals. No more guessing based on age, interests, or browsing behavior. You knew who you were reaching because you had started with a list of known identities.
This approach transformed consumer advertising. Brands could retarget past purchasers, reach lookalikes of their best customers, and suppress ads to people who had already converted. The concept spread quickly. Around 2014–2016, people-based marketing became the standard for sophisticated consumer campaigns. Other platforms — Google, Twitter, Pinterest — adopted similar matching capabilities.
The key insight was deterministic matching: start with known identities (emails, phone numbers), hash them for privacy, and match to platform user IDs. That approach is more accurate than probabilistic targeting, which infers audience membership from cookies, IP addresses, or contextual signals. Deterministic matching says "this is Jane Smith"; probabilistic says "this user probably fits our profile." The shift from probabilistic to deterministic was a fundamental change in how advertisers thought about audience reach.
People-Based Marketing in B2B
The same principle applies in B2B, but the application is different. Instead of consumer email addresses (Gmail, Yahoo), you use work email addresses. You match those work emails to platform profiles — LinkedIn, Meta, Google, Reddit — and serve targeted ads to named decision-makers. The goal is to reach every member of the buying committee, not just one champion.
The B2B challenge is that work emails do not match consumer platforms as easily as personal emails. Many people use personal accounts for Facebook and Instagram; work emails may not be linked to those profiles. LinkedIn has better work-email coverage, but even there, native platform uploads typically achieve only ~30% match rates. You upload a list of 1,000 contacts and reach roughly 300.
That gap drives the need for enrichment and identity resolution. Contact data matching platforms enrich your list — adding hashed identifiers, device IDs, and other signals — and sync to ad networks. With enrichment, match rates climb to 70–90%. The difference between ~30% and 70–90% is the difference between partial and full coverage of your buying group. Gartner research shows 6–10 stakeholders per typical enterprise deal. If you are only reaching ~30% of your list, you are missing most of the committee.
Key stats:
- 6–10 stakeholders per typical B2B deal (Gartner)
- ~30% native match rate vs 70–90% with contact data matching
- 72% of B2B buyers expect personalized interactions (Forrester)
- 85% higher close rates with contact-level approach
- 67% faster deal velocity when full buying group engaged
- 24% of B2B marketing leaders planning PBM implementation (Influ2/Forrester)
People-Based vs. Account-Based Marketing
People-based marketing and account-based marketing (ABM) are related but distinct. PBM targets individuals; ABM targets accounts. PBM matches actual people to your list; ABM matches company attributes (industry, size, revenue) to find accounts that fit your ideal customer profile. PBM delivers role-specific messaging to each person; ABM often relies on one champion to carry your message to the rest of the committee.
| Dimension | Account-Based Marketing | People-Based Marketing |
|---|---|---|
| Targeting unit | Account (company) | Individual contact |
| Matching logic | Company attributes (industry, size) | Actual people (email, identity) |
| Personalization | Account-level messaging | Role-specific, person-level messaging |
| Attribution | Account engagement signals | Named-individual engagement |
| Champion dependency | High — depends on one insider | Low — you reach all stakeholders directly |
| Match rates | ~30% (native platform uploads) | 70–90% (via contact data matching) |
The champion dependency difference matters in practice. In ABM, if your champion leaves the company, gets overruled, or simply fails to convince the room, your deal stalls. People-based marketing reduces that risk by ensuring every stakeholder has heard your message before the final decision. You are not hoping one person will carry the torch; you are reaching everyone directly.
The two approaches are not mutually exclusive. Many teams run ABM for account selection and pipeline management, then add people-based targeting to reach every committee member. For a deeper comparison, see our guides on ABM vs PBM and ABM vs. contact-based marketing.
Why B2B Teams Are Adopting People-Based Marketing
Several forces are driving adoption. First, buying committees are getting larger. Gartner's research on 6–10 stakeholders per deal is widely cited; complex purchases involve even more. Traditional ABM, which often relies on one champion to rally the rest, breaks down when the committee grows. You need to reach everyone directly.
Second, cookie deprecation makes probabilistic targeting less reliable. Third-party cookies are being phased out; IP-based and contextual targeting are less accurate than they used to be. Deterministic people-based matching does not depend on cookies. You start with known identities and match them to platform profiles. The approach is more durable as the privacy landscape evolves.
Third, B2B buyers expect B2C-level personalization. Forrester research shows that 72% of B2B buyers expect personalized interactions. They are used to consumer experiences — Netflix, Amazon, Spotify — that feel tailored to them. Generic account-level messaging falls short. People-based marketing delivers role-specific content: ROI messaging for CFOs, technical documentation for IT evaluators, product demos for end users.
The data supports the shift. Deals move 67% faster when the full buying group is engaged. Close rates are 85% higher with contact-level coverage. According to Influ2 and Forrester, 24% of B2B marketing leaders are planning people-based marketing implementation. The trend is toward individual-level targeting, not away from it.
How ContactLevel Enables People-Based Marketing
ContactLevel is the platform that makes people-based marketing work in B2B. You upload your ICP contact list — names, work emails, job titles, companies — and ContactLevel enriches the data, syncs to LinkedIn, Meta, Google, and Reddit, and delivers 70–90% match rates. Native platform uploads typically achieve ~30%; ContactLevel's contact data matching closes that gap.
The workflow is straightforward. Build your list from your CRM, sales intelligence tool, or manual research. Upload it to ContactLevel. The platform enriches and syncs to ad networks. You create role-specific campaigns — segment by job title or buying role — and serve personalized ads to each segment. When contacts engage — ad clicks, website visits, LinkedIn accepts — you get individual-level attribution. You know exactly who engaged, not just that someone at the account did.
That attribution flows to sales. Instead of "someone at Acme Corp visited our site," you get "Jane Smith, CFO at Acme, clicked our ROI ad and visited the pricing page twice this week." Sales gets a warm handoff with context. For more on the advertising mechanism, see our guide on contact level advertising.
People-based marketing in B2B is the same principle that transformed consumer advertising: target the exact people you intend to reach, with deterministic identity matching. The contact-level approach — reaching every member of the buying group with role-specific messaging — is how modern B2B teams run precision campaigns.
