# B2B Marketing Has Changed. Has Your Platform Kept Up?

6sense focuses on intent data and account identification. Demandbase offers broad ABM orchestration. Metadata takes a different approach: AI agents that build audiences, generate creatives, negotiate bids, and launch campaigns autonomously — with 160 MCP tools any LLM can call. This guide compares all three with verifiable data so you can decide which fits your needs.

### Metadata.io — AI-Native Campaign Execution

Metadata doesn't just automate campaigns — it deploys a team of AI agents that run your entire demand generation program. **Metadata** is a true AI agency: 7 specialized agents (Creative, Content, Bid, Enrichment, Targeting, and Optimization) that work 24/7 across every channel. A single natural language prompt can build audiences, generate on-brand creatives, set budgets, and launch a campaign — or set up a $1M quarter in draft for your review.

Under the hood, **160 MCP tools** expose the full platform to any LLM. Claude or any LLM — any model that supports the open Model Context Protocol can call Metadata's APIs directly. This isn't a chatbot bolted onto a dashboard. It's programmatic access to audience creation, creative generation, campaign management, bid optimization, and analytics — all through a standardized, open protocol.

The platform uses any B2B data — CRM, marketing automation, revenue, and proprietary MetaMatch (1.5B+ profiles) — to drive pipeline and revenue impact. The Bid Agent logs into ad channels 50x/day to negotiate the lowest bid. The Enrichment Agent cross-references 10+ data sources and deploys human workers to verify each lead. The Creative Agent extracts your brand DNA and generates on-brand ad creatives at scale.

Metadata includes **Insights** for company-level ad engagement, website activity and CRM context. See which companies view, engage with or convert on your ads, even without a form fill, and alert sales when target accounts engage.

### 6sense — Reactive Intent Signals

6sense is built around proprietary intent data — identifying which accounts are researching solutions in your category. This is a genuine strength for sales-led organizations. However, as buyer research shifts to LLMs, Reddit, dark social, and peer conversations, the signals that traditional intent models rely on are becoming less complete.

Intent data based on website visits, keyword search activity, and similar digital signals can be delayed or incomplete when buyers research through channels that don't leave traditional tracking signals. 6sense also requires operationalization: teams typically 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.

#### AI-Native

7 specialized AI agents run your demand gen 24/7. 160 MCP tools let any LLM build audiences, generate creatives, and launch campaigns programmatically.

#### Open Protocol

Built on the open Model Context Protocol. Works from Claude Code, Claude Desktop, or any LLM — not locked into one vendor's chatbot.

#### Autonomous Execution

From a single prompt to a fully configured campaign: audiences, creatives, offers, budgets, and channel allocation — all in one pass.

#### More Pipeline, Less Headcount

Bid Agent negotiates 50x/day. Creative Agent generates on-brand ads. Enrichment Agent verifies every lead. No 5-person media team required.

#### Intelligence-First, Not Execution-First

6sense and Demandbase document read-only MCP access to data and insights. Their documented MCP tools do not execute campaigns.

#### MCP Access

Both support external AI assistants through MCP. Compare the actions each integration supports, as well as the data it can retrieve.

#### Execution Scope

Read-only MCP access does not describe every automation feature in either platform. Review each vendor's campaign and workflow capabilities separately.

#### Higher Total Cost of Ownership

6sense starts at $55K/yr with 18-month minimums. Demandbase starts at $65K/yr. Both typically require dedicated admins for full operationalization.

### Where Each Platform Excels

Every platform on this page has real strengths. An honest evaluation starts by understanding what each does well, then matching that to your specific needs.

#### Strong Intent Data and Predictive Analytics

6sense has invested heavily in intent signal aggregation and predictive account scoring. For sales-led organizations that prioritize knowing which accounts are in-market, this is a genuine strength. Their large enterprise install base (1,300+ G2 reviews) reflects deep adoption among companies with dedicated RevOps teams.

**Where Metadata differs:** Metadata focuses on executing campaigns, not just identifying accounts. If your bottleneck is knowing who to target, 6sense may be a fit. If your bottleneck is actually running multi-channel paid programs at scale, Metadata is built for that.

#### Robust ABM Orchestration and Salesforce Integration

Demandbase offers one of the most comprehensive ABM suites available, covering account intelligence, engagement scoring, orchestration, and display advertising. Their deep Salesforce integration and 1,900+ G2 reviews reflect a mature product with broad enterprise adoption. Teams that need a full-stack ABM orchestration layer often land here.

**Where Metadata differs:** Demandbase orchestrates across many GTM motions. Metadata goes deeper on paid media execution specifically — autonomous campaign building, AI creative generation, and campaign optimization across 12 channels.

#### Excellent Email Automation and SMB/Mid-Market Ecosystem

HubSpot's Marketing Hub is arguably the best email automation and inbound marketing platform for SMB and mid-market companies. The all-in-one CRM, content, and marketing automation ecosystem is hard to beat for teams that want one vendor for everything. At $3,600/mo for Enterprise, it's also meaningfully less expensive than ABM-specific platforms.

**Where Metadata differs:** HubSpot excels at inbound and email. Metadata is purpose-built for outbound paid media — multi-channel campaign execution, audience targeting with B2B data, and AI-driven optimization. Many Metadata customers use HubSpot alongside Metadata.

#### Enterprise Workflow Customization and Adobe Ecosystem

Marketo remains the gold standard for enterprise marketing automation workflows. Its deep customization, sophisticated lead scoring, and tight integration with the Adobe Experience Cloud ecosystem make it a strong choice for large organizations with complex nurture programs. Pricing ranges from $895 to $3,195/mo depending on tier.

**Where Metadata differs:** Marketo is a marketing automation platform (email, nurture, scoring). Metadata is a paid media execution platform (campaigns, audiences, creatives, bid optimization). They serve different parts of the funnel and often run side by side.

#### 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 Actually Does

**Metadata is an AI agency** — not a chatbot, not a copilot, not a prompt wrapper around a dashboard. It's 7 specialized AI agents backed by 160 MCP tools that execute real campaigns on real ad channels.

The **Creative Agent** scrapes your website, extracts your brand DNA (colors, fonts, logo, tone), and generates on-brand ad creatives — images, headlines, and copy — without a designer. The **Content Agent** scans your site to find every case study, whitepaper, and offer to use in campaigns. The **Bid Agent** logs into LinkedIn, Meta, and Google Ads 50 times a day to negotiate the lowest possible bid on every ad.

The **Enrichment Agent** cross-references 10+ data sources, then deploys a human worker to verify each profile before it reaches your sales team. The **Targeting Agent** builds firmographic, technographic, intent, and retargeting audiences across every channel. The **Optimization Agent** runs multivariate experiments and reallocates budget to what's working.

### 160 MCP Tools: Open, Programmable, Composable

Metadata exposes the entire Metadata platform through the **Model Context Protocol** — the open standard for connecting AI models to external tools. This means any MCP-compatible LLM can:

**Build audiences** — firmographic, technographic, Bombora intent, LinkedIn native, Meta native, retargeting. **Generate creatives** — AI image generation with brand kit enforcement. **Create campaigns** — wire up audiences, ads, offers, channels, and budgets. **Manage spend** — budget groups, daily pacing, bid optimization. **Analyze performance** — deep funnel stats, experiment results, account-level attribution.

This isn't "AI-powered insights" or a natural language query layer. It's full programmatic execution — the same API calls a human would make through the UI, but driven by AI at machine speed.

### Works With Your AI Stack

Metadata works from **Claude Code** (terminal), **Claude Desktop**, the **Metadata web app**, or any MCP-compatible client. You're not locked into one vendor's AI. Bring your own LLM.

#### Read-only access and campaign execution

6sense and Demandbase document MCP tools that retrieve data and insights. metadata.io's MCP tools also support campaign execution and optimization. Check each integration's current tools and permissions against the work you want your AI assistant to perform. MCP documentation alone does not establish the full automation capabilities of a platform.

### Company-level insights without a form fill

See which companies view, engage with or convert on your ads, even without a form fill. Use company-level activity to prioritize accounts and guide campaign targeting.

### Account Heat Scores & Engagement Metrics

Insights generates **account heat scores** and engagement metrics that sync directly to Salesforce. Customizable engagement criteria — LinkedIn impressions, website visits, content downloads — let you define what "engaged" means for your business, not what a vendor's black-box model decides.

### Chronological Account Timeline

Available ad engagement, website visits and CRM activity appear in a timeline for each account. Sales can use this company-level context to plan follow-up.

### Sales Alerts

When a target account hits your site or engages with a campaign, sales gets notified immediately. Not in a weekly report. Not buried in a dashboard. Real-time alerts so reps can act while the buyer is still warm.

### Multi-Channel Data Consolidation

Insights consolidates engagement data from LinkedIn, Meta, Google Ads, your website, and CRM into a single unified view. When engagement data is siloed across platforms, it's difficult to act on. Insights eliminates that gap.

### Multi-Channel Retargeting

Use company-level engagement to guide retargeting audiences across supported channels. Known contacts and CRM lists can also inform audience targeting; they are distinct from identifying an anonymous site visitor.

### Why This Matters vs. 6sense and Demandbase

6sense and Demandbase charge separately for their intent and visitor identification products, often bundled into premium tiers. With Metadata, **Insights is included** — visitor ID, account scoring, sales alerts, and journey mapping come standard. You don't pay extra for ABM intelligence on top of your campaign execution platform.

#### "Spotlight has saved us hours of work cleaning up data and building audiences."

#### You need better audiences or help running paid campaigns

You can use metadata.io for audiences alone and run campaigns yourself. Add campaign execution and optimization, or use the agentic workflow when you need it.

#### 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.

#### 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.

#### 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.

#### You want AI to run your demand gen, not just inform it

You're ready for AI agents that build audiences, generate creatives, negotiate bids, and manage campaigns autonomously. You want to operate your paid media program from natural language — through Claude or any LLM — with full transparency and human approval at every step.

## Where Metadata May NOT Be the Right Fit

No platform is right for everyone. Here are the cases where Metadata is probably not what you need.

- **If you only run organic or content marketing**Metadata is a paid demand gen platform. If you don't run paid ads, we're not the right tool.
- **If you need a full-stack CRM**We integrate with Salesforce and HubSpot but don't replace them. Metadata is a demand gen execution layer, not a CRM.
- **If you need B2C consumer targeting**Our data and audiences are B2B-specific. We don't support B2C consumer targeting.
- **If you want a hands-off managed service**Metadata is a platform, not an agency. We provide the tools and AI; your team runs the campaigns, with our support.

For everyone else — Metadata is purpose-built for AI-driven demand gen execution across paid channels.

## Ready to See What AI-Native Demand Gen Looks Like?

160 MCP tools. 7 AI agents. Campaigns built from natural language. If you're ready to move on, Metadata will work with you to offset the cost of your current agreement.
