If you’re a B2B SaaS company, choosing the best demand generation agency for you is one of the most high-stakes decisions you’ll make. The right partner will build you a pipeline engine that drives revenue, aligns with your sales team, and scales predictably.

To make it easier for you, we’ve reviewed the six best demand generation agencies trusted by growth-stage SaaS companies ($5M–$100M annual recurring revenue). Let’s get into it.

1. Powered by Search

Best for: Mid-market to enterprise B2B SaaS companies that need a full-funnel, revenue-first marketing strategy.

Powered by Search is the only SaaS marketing agency on this list that works exclusively with B2B SaaS companies. That depth of focus pays off: they’ve built proprietary frameworks like the SaaS Demand Gen Pyramid and are known for mapping every dollar of spend to pipeline. Their “bottom-of-funnel-first” approach flips the typical agency playbook by prioritizing revenue over vanity metrics.

If you want a strategic partner who’ll help you guide budgeting, targeting, messaging, and even RevOps, Powered by Search should be at the top of your SaaS marketing agencies list.

What makes them unique:

• SaaS-exclusive focus: Every insight, strategy, and playbook is built specifically for the SaaS go-to-market motion.
• Full-funnel integration: Paid media, SEO, lifecycle marketing, RevOps, and sales enablement are tightly aligned.
• Attribution realism: They triangulate CRM, ad platform, and qualitative data to paint a true picture of what drives revenue.
• Long-term partners: Most clients engage for 12+ months to build sustainable pipeline engines.

Notable clients include: Basecamp, SentinelOne, Fortra, ThreatX

Not ideal if you’re a seed-stage startup with less than $10,000 in media spend or just need a quick creative refresh.

2. Refine Labs

Best for: B2B SaaS teams looking to ditch the MQL hamster wheel and drive a high-intent pipeline.

Refine Labs is the torchbearer of “Demand Gen 2.0.” They helped popularize concepts like declared intent, dark social, and self-reported attribution. Their framework focuses on revenue-driving leads who convert fast, not gated content leads that waste your SDRs’ time.

They’re great if you need to convince your CEO and CRO that marketing is more than MQLs, and have the data to prove it.

What makes them unique:

• Modern frameworks: HIRO pipeline, split the funnel, and hybrid attribution reshape how teams measure success.
• Demand creation plus capture: They balance upstream education (via zero-click content) with bottom-of-the-funnel conversion tactics.
• C-suite enablement: Refine Labs arms marketing leaders with the data and narrative to shift company-wide metrics toward pipeline, CAC, and payback.

Notable clients include: Clari, Loxo, Splash

Not ideal if you need results yesterday, or you’re unwilling to rethink old lead-gen KPIs.

3. Directive Consulting

Best for: B2B SaaS marketers who need a performance partner across SEO, paid search, and CRO, with revenue as their north star.

With experience across 200+ SaaS companies and frameworks like customer-led SEO, Directive Consulting prioritizes revenue over rankings and conversions over impressions. It’s ideal if your exec team is asking, “Where’s the pipeline?” and you want to show dashboards that answer with dollar signs.

What makes them unique:

• Pipeline-driven SEO and PPC: Every strategy ladders up to SQLs, pipeline, and revenue, not traffic for traffic’s sake.
• Full-funnel support: From CRO and landing page design to analytics and reporting, they offer a range of services.
• Startup-friendly options: Directive has $5,000/month growth packages for early-stage teams and performance-based pricing for later-stage ones.

Notable clients include: Xactly, Aegis Software, Congruity360

Not ideal if you’re purely focused on brand awareness or creative; Directive is a performance-first shop.

4. Omniscient Digital

Best for: SaaS companies investing in content and SEO with a mandate to show pipeline, not just page views.

Omniscient Digital is run by ex-HubSpot and Shopify marketers who know how to scale content that drives revenue. They go beyond writing blog posts, offering full-stack SEO strategy, positioning help, and conversion-focused content operations.

What makes them unique:

• Operator-led: They’ve been in your shoes as in-house SaaS marketers.
• Revenue content: Their content is designed to generate signups, MQLs, and SQLs.
• Execution engine: They produce high-quality content at scale, optimized for conversion and discoverability.

Notable clients include: Jasper, Adobe, Smartling

Not ideal if you want quick lead gen from paid channels or to operate outside B2B SaaS.

5. Tuff

Best for: Series A–B SaaS companies that want a fractional, cross-functional growth team to drive early traction.

Tuff is a plug-and-play growth team for companies that need marketing muscle but aren’t ready to hire a big internal team. From SEM and SEO to CRO and analytics, they move fast, test everything, and double down on what works. They’re great for lean SaaS teams who need growth acceleration and don’t have time to babysit an agency.

What makes them unique:

• Embedded team model: They work in your Slack and Asana, like in-house teammates.
• Rapid experimentation: Tuff employs quick sprints and lean tests, with no bloated strategies.
• Channel-agnostic: Whether it’s paid, SEO, email, or CRO, they go where the results are.

Notable clients include: Nova Credit, Thnks, Multiverse

Not ideal if you already have a large in-house team and only need a niche service.

6. Single Grain

Best for: Growth-stage and enterprise SaaS companies looking for a full-service agency that balances creative outputs with performance.

Led by Eric Siu, Single Grain is a full-stack agency that excels at running integrated campaigns across SEO, paid media, video, CRO, and more. They also bring their own SaaS product (ClickFlow) and podcast (Marketing School) pedigree into client work. If you want a marketing partner that challenges your assumptions and builds a full-funnel strategy that wins boardroom buy-in, Single Grain fits the bill.

What makes them unique:

• Multi-channel mastery: Between SEO, YouTube ads, podcast media buys, and TikTok, nothing is off limits.
• Enterprise and startup experience: They’ve helped everyone from Amazon to Nextiva.
• Content plus distribution engine: They’re creators themselves, so they get both sides of demand gen.

Notable clients include: Amazon, Uber, Salesforce

Not ideal if you’re very early-stage or only need one specific service, like SEO or PPC.
