B2B Demand Generation Agency Comparison

Directive

What they do: Directive provides performance marketing for B2B tech companies — paid search, paid social, SEO, and CRO focused on pipeline metrics rather than vanity metrics.

Pricing: Retainers typically $10,000-$25,000/month. Hourly rates $100-$149 for project work.

Services: Paid media, SEO, content, CRO, analytics. Focus on cost-per-qualified-opportunity.

Best for: B2B SaaS companies spending $10,000+/month on paid media who want pipeline accountability.

The honest take: Directive's obsession with pipeline metrics over clicks differentiates them. They'll tell you when channels aren't working and reallocate spend. The downside: their methodology requires sufficient ad spend to generate statistical significance. Companies spending less than $10k/month on paid may not see the full benefit. For funded SaaS with real media budgets, Directive delivers accountability.

Refine Labs

What they do: Refine Labs pioneered the "demand creation" approach — building category awareness through content and social rather than capturing existing demand through ads.

Pricing: Enterprise pricing, typically $25,000-$50,000+/month. Best fit for companies with $50k+/month paid media budgets.

Services: Demand strategy, paid media, content, creative, measurement frameworks.

Best for: Mid-market and enterprise SaaS ($30M+ ARR) ready to invest in brand-led demand generation.

The honest take: Refine Labs changed how B2B thinks about demand gen. Their framework — demand creation over demand capture — works for companies with patience and budget. The downside: this isn't for early-stage companies needing immediate pipeline. The approach requires months to show results and significant investment. Their Vault product ($500/month) lets smaller companies access frameworks without agency engagement.

CIENCE

What they do: CIENCE provides multi-channel outbound — SDR services, data, and technology for B2B pipeline generation.

Pricing: Multi-channel outbound starts at $2,499/month plus $5,000 setup. Flexible month-to-month contracts available.

Services: SDR as a service, data enrichment, multi-channel outreach (email, phone, LinkedIn, ads).

Best for: Companies wanting to test or scale outbound without building in-house SDR teams.

The honest take: CIENCE's integrated approach — data, SDRs, and technology in one vendor — simplifies outbound. Month-to-month flexibility is rare in the space. The downside: outsourced SDRs never know your product as well as in-house reps. Quality varies by rep assignment. CIENCE works best as a pipeline supplement or proof-of-concept before building internal teams.

Belkins

What they do: Belkins specializes in B2B appointment setting through omnichannel outreach — email, LinkedIn, and sales enablement.

Pricing: Starting at $5,000/month with 3-month minimum. Typical range $3,000-$15,000/month depending on scope.

Services: Appointment setting, email outreach, LinkedIn outreach, sales enablement, CRM management.

Best for: Companies that want meetings booked, not just leads generated.

The honest take: Belkins focuses on the metric that matters: meetings with qualified prospects. Their appointment-setting model aligns incentives better than cost-per-lead. The downside: 3-month minimums mean commitment before seeing results. Meeting quality depends on ICP definition and list quality. Works best when you provide clear qualification criteria and feedback loops.

SalesRoads

What they do: SalesRoads provides dedicated SDR teams for B2B appointment setting and lead qualification.

Pricing: All programs start at $9,400/month.

Services: Dedicated SDRs, appointment setting, lead qualification, CRM integration.

Best for: Companies wanting dedicated SDR resources without hiring and managing internally.

The honest take: SalesRoads' dedicated model means you get consistent reps who learn your business. This beats the rotating rep model some competitors use. The downside: $9,400/month is real money — nearly the cost of a junior in-house SDR with benefits. The math works when you factor in management overhead, tools, and ramp time that SalesRoads absorbs.

Velocity Partners

What they do: Velocity Partners builds B2B demand through high-quality content — thought leadership, eBooks, videos, and interactive content that positions brands as category leaders.

Pricing: Custom pricing, typically $10,000-$20,000/month for ongoing retainers. Project work available.

Services: Content strategy, thought leadership, eBooks, videos, interactive content, brand positioning.

Best for: B2B companies that want to win through ideas and content, not just outbound volume.

The honest take: Velocity Partners creates content that actually gets read and shared — rare in B2B. Their work builds brands, not just pipelines. The downside: content-led demand gen takes time. If you need pipeline this quarter, content won't deliver. For companies playing long-term brand games, Velocity is among the best. For immediate pipeline needs, add outbound.

Ironpaper

What they do: Ironpaper provides full-funnel B2B demand generation — strategy, content, paid media, and marketing automation for complex sales.

Pricing: Custom pricing, typically $8,000-$15,000/month for comprehensive programs.

Services: Demand gen strategy, content, paid media, marketing automation, lead nurturing, analytics.

Best for: B2B companies with complex, considered purchases needing full-funnel support.

The honest take: Ironpaper's strength is integrated execution across the funnel. They connect top-of-funnel content to bottom-of-funnel conversion. The 4.8-star G2 rating reflects client satisfaction. The downside: full-funnel agencies can spread thin across too many tactics. Ensure your engagement focuses on your biggest gaps rather than trying to do everything at once.

Transmission

What they do: Transmission is the world's largest independent B2B marketing agency, specializing in enterprise ABM and demand generation powered by their Propulsion OS platform.

Pricing: Enterprise pricing, typically $20,000-$50,000+/month. Global capabilities.

Services: ABM, demand generation, content, creative, media, data, technology (Propulsion OS).

Best for: Enterprise companies running global, multi-market demand generation programs.

The honest take: Transmission operates at enterprise scale — ~$102M revenue, global offices, proprietary tech platform. For companies running demand gen across multiple markets and regions, the infrastructure matters. The downside: this isn't for mid-market or SMB. Minimum engagements and enterprise pricing filter to large organizations. For enterprise ABM at scale, Transmission competes with the holding company agencies.

GrowthSpree

What they do: GrowthSpree provides demand generation for early-stage B2B SaaS at accessible pricing.

Pricing: Flat $3,000/month retainer.

Services: Demand gen strategy, content, paid media management, analytics.

Best for: Seed to Series A SaaS companies that need demand gen help but can't afford enterprise agencies.

The honest take: GrowthSpree's $3,000/month flat rate is refreshingly simple and accessible for early-stage companies. They understand startup constraints. The downside: flat pricing means standardized scope. If you need heavy customization or enterprise complexity, the model may not flex. For early-stage SaaS testing demand gen channels, GrowthSpree offers low-risk entry.

The B2B Playbook

What they do: The B2B Playbook provides demand generation strategy, training, and implementation support — teaching teams to fish rather than fishing for them.

Pricing: Retainers start from $1,580/month.

Services: Demand gen strategy, training, implementation support, coaching.

Best for: Companies that want to build internal demand gen capability, not outsource it.

The honest take: The B2B Playbook's model is different: they teach and support rather than just execute. This builds internal capability that stays when the engagement ends. The downside: you need someone internal to do the work. If you want fully outsourced execution, look elsewhere. For companies building marketing teams and wanting guidance, this approach builds lasting capability.

New North

What they do: New North provides B2B marketing services — demand generation, content, design, and web development for mid-market companies.

Pricing: Retainers typically start around $5,000/month.

Services: Demand generation, content marketing, web design, branding, marketing strategy.

Best for: Mid-market B2B companies wanting integrated marketing support.

The honest take: New North positions as a full-service B2B agency at mid-market pricing. They cover strategy through execution across channels. The downside: breadth can mean less depth than specialized agencies. If you need deep expertise in one area (say, paid media), a specialist may outperform. For companies wanting one agency relationship covering multiple needs, New North simplifies vendor management.

Inbox Insight

What they do: Inbox Insight provides intent-driven demand generation — using buyer intent data to identify and engage accounts showing purchase signals.

Pricing: Custom pricing, typically $10,000-$20,000/month for integrated programs.

Services: Intent data, content syndication, lead generation, ABM, demand generation.

Best for: Companies wanting to prioritize accounts based on actual buying signals.

The honest take: Inbox Insight's intent-first approach means focusing on accounts that are actually in-market. This beats spraying messages at cold lists. The downside: intent data quality varies, and acting on intent requires fast follow-up. The data is only valuable if your sales team can respond quickly. For companies with SDR capacity to work intent signals, this approach improves efficiency.

Metadata.io

What they do: Metadata.io provides a demand generation platform with services — automating paid media across channels with AI-powered optimization.

Pricing: Platform starts around $5,000/month. Full platform with audience modules approximately $60,000/year.

Services: Paid media automation, audience targeting, experimentation, ABM, demand generation.

Best for: Marketing teams with $20,000+/month paid media spend wanting to automate and optimize campaigns.

The honest take: Metadata.io is more platform than agency, but their services layer helps teams get value from the tech. The automation is powerful for teams running significant paid media. The downside: the platform cost only makes sense with meaningful ad spend. Early-stage companies with small budgets won't see ROI. For growth-stage companies scaling paid demand gen, Metadata accelerates experimentation.

310 Creative

What they do: 310 Creative specializes in HubSpot-powered demand generation for B2B SaaS — inbound marketing, content, and RevOps.

Pricing: Retainers typically start around $6,000/month.

Services: HubSpot implementation, inbound marketing, content, demand gen, RevOps.

Best for: B2B SaaS companies using or adopting HubSpot who want integrated demand generation.

The honest take: 310 Creative's HubSpot specialization means deep platform expertise and partnership benefits. If you're committed to HubSpot, they'll maximize your investment. The downside: HubSpot-centric means less flexibility if you're using other tools. For HubSpot-committed companies, the specialization is a feature. For multi-tool environments, consider generalists.

Powered by Search

What they do: Powered by Search provides organic-led demand generation for B2B SaaS — SEO, content, and conversion optimization.

Pricing: Retainers typically start around $8,000/month.

Services: SEO, content strategy, content production, conversion optimization.

Best for: B2B SaaS companies that want to build organic demand generation as a sustainable channel.

The honest take: Powered by Search bets on organic over paid — building demand through search visibility and content that compounds. The approach is sustainable long-term. The downside: SEO takes months to show results. If you need pipeline this quarter, organic won't deliver fast enough. For companies with runway to invest in sustainable demand gen, organic-first makes sense.

FAQ

How much does a B2B demand generation agency cost?

B2B demand generation agencies typically charge $3,000-$25,000/month on retainer. Early-stage programs start around $3,000-$5,000/month. Mid-market companies typically spend $8,000-$15,000/month. Enterprise programs with ABM and multi-channel orchestration run $15,000-$50,000/month.

What's the difference between demand generation and lead generation?

Demand generation creates awareness and interest in your category and solution. Lead generation captures contact information from interested prospects. Demand gen is top-of-funnel (content, brand, education); lead gen is conversion-focused (forms, gated content, demos). Most agencies do both, but emphasis varies.

How long before demand generation shows results?

Outbound demand gen (SDR services, email campaigns) can show meetings within 30-60 days. Paid media typically shows patterns within 60-90 days. Content and organic demand gen takes 6-12 months for meaningful results. Set expectations with your agency based on the channels you're investing in.

Should I hire in-house or use an agency for demand gen?

Use an agency when: you lack specialized expertise, need to move quickly, or want to test channels before committing headcount. Hire in-house when: demand gen is core to your competitive advantage, you have volume to justify dedicated roles, and you want institutional knowledge. Many companies use agencies to prove channels then bring successful programs in-house.

What metrics should I track with a demand gen agency?

Track pipeline metrics, not vanity metrics. Key metrics: Marketing Qualified Leads (MQLs), Sales Qualified Leads (SQLs), opportunities created, pipeline generated, cost per opportunity, and ultimately closed revenue influenced. Avoid optimizing for clicks, impressions, or unqualified leads. Align on metrics before engagement starts.
