B2B Marketing Has Changed. Has Your Platform Kept Up?

6sense still relies on outdated intent signals and channel-by-channel audience builds. Demandbase layers on complexity without solving the execution gap. Metadata ingests any data you choose, matches audiences across channels, and automates every campaign from one platform.

The Old Go-to-Market Playbook Has Changed
Back when buyers were still Googling everything and clicking through to websites, 6sense had a niche. But buyers don't research like that anymore.

Metadata.io — Proactive, Autonomous Campaign Execution

Metadata automates campaigns using real person-level data with full transparency and control of targeting, timing, and outcomes. One-click import of your audiences, campaigns, and CRM data. Instantly launch, test, and optimize across all channels.

The platform uses any B2B data — CRM, marketing automation, revenue, and proprietary MetaMatch (1.5B+ profiles) — to drive pipeline and revenue impact. AI agents handle targeting, bidding, creative, budget, and reporting, with a human in the loop to strategize and monitor progress.

Metadata also includes Insights — website visitor identification at both the contact and company level, even before a visitor fills out a form — as well as sales alerts that notify reps when target accounts engage.

6sense — Reactive Intent Signals

6sense is built around proprietary intent data — identifying which accounts are researching solutions in your category. But today's buyers bounce between LLMs like ChatGPT and Claude, go to Reddit and dark social to do research. They don't leave neat cookie crumbs. They don't care about your scoring model.

That's why intent data built on digital breadcrumbs — website visits, basic keyword search activity, and lagging signals — is often late, incomplete, or just plain wrong. 6sense also requires significant operationalization: teams must build audiences per channel and coordinate execution across GTM silos.

Demandbase — Broad but Complex

Demandbase provides an ABM suite with account-level intelligence, engagement scoring, and sales enablement features. It acquired Engagio and InsideView, giving it broad capabilities. But like 6sense, it works best when you have the team and time to implement it fully. G2 reviewers note it can feel feature-heavy for non-power users, and CRM integrations sometimes require more effort than expected.

How PII-Based Targeting Opens Up Consumer Channels for B2B

Most B2B ad platforms can only target by corporate email, which limits you to LinkedIn and display. Metadata resolves B2B buyers across personal emails, cell phones, and mobile device IDs — which means you can run B2B campaigns on channels like Facebook, Instagram, and Reddit that were historically consumer-only. Larger inventory means lower CPMs and more room to scale.

What Metadata Customers Are Saying
Real results from real teams running campaigns on Metadata.
"We've seen a huge revenue increase over the last two years. We went from a million dollars a quarter to now almost a million dollars a month, and we are doubling in size year over year. Metadata is probably 75% of that."
Mike Smith
VP of Revenue Marketing, LaunchDarkly
"Before Metadata, we were running ads natively on one channel and getting junk. We turned on Metadata, and it was 95% accurate in terms of the titles and the personas that we wanted to target. Using native channel targeting, our CPL was about $225. In our first Metadata campaign, the CPL was $67."
Blake Cohlan
Senior Director of Growth Marketing, SupportLogic
"Part of it is just having one place for all this stuff I'm trying to juggle in my head all the time and knowing that I can reference it immediately. So when the CEO says, 'What's going on?' I can show them instantly what's happening, why it's working or not working, and what we're going to do next."

Which One Should You Choose?
The best platform depends on your team's size, budget, go-to-market model, and what problem you're actually trying to solve.

You have significant ad spend and want it to work harder

Your team is running $50K-2M+/month in paid campaigns across multiple channels, and you need to automate the operational work and see clear spend-to-pipeline attribution.

Look at Metadata.io

You need predictive account identification

Your go-to-market is sales-led and your SDR/BDR team needs intent data and account scoring to prioritize outreach. Be aware that buyer research patterns have shifted significantly.

Look at 6sense

You want a single ABM platform

You have the team and timeline for a full-suite ABM platform: account intelligence, advertising, orchestration, and sales enablement in one place. Plan for a longer implementation cycle.

Look at Demandbase

You're a mid-market team scaling fast with a small marketing ops team

You don't have a dedicated admin. You need something that gets to value in weeks not months, includes visitor identification and sales alerts out of the box, and doesn't require an 18-month contract.

Look at Metadata.io
Questions Worth Asking in Your Evaluation
Regardless of which platform you lean toward, these questions will help you cut through the sales pitch.
Platforms that rely on signals buyers don't leave anymore — cookies, site visits, keyword searches — produce results that are often late, incomplete, and mismatched. Ask how the platform validates leads and ties them to pipeline. Metadata connects to any data source you choose, builds precise audiences, and matches them across channels. Leads are enriched, validated, and tied to pipeline — not just "engagement."
Get specific on implementation timeline, onboarding resources required, and when past customers started seeing pipeline impact. G2 setup times (~1 month for Metadata, ~2 months for Demandbase, ~3 months for 6sense) are directional but your mileage will vary. Metadata offers one-click import, a unified platform, and AI agents running campaigns from day one.
Honestly assess your team's capacity. Some platforms are powerful but require significant ongoing management. If you're a team of 3-5, that matters a lot. Metadata is designed to run without a dedicated admin; 6sense and Demandbase typically require one, especially during the first 6 months.
Ask each vendor to show you how they attribute pipeline. "Influenced" can mean the platform touched an account at some point before a deal opened — which may or may not have been causal. "Sourced" means the platform directly generated the lead or opportunity. Metadata focuses on sourced pipeline; 6sense and Demandbase primarily report on influenced pipeline.
With Metadata, sales gets qualified, enriched leads tied to revenue — not ghost hunting on ambiguous intent signals. Ask any vendor to show you what the sales team actually receives and how quickly they can act on it.
Reference calls with companies similar in size and industry to yours are the most valuable part of any evaluation. Ask for them early. Metadata customers include Zoom, Apptio (IBM), Docebo, N-Able, Webex, Monotype, and Bloomreach — we're happy to connect you with any of them.
