The best digital marketing agencies for B2B SaaS companies in 2026 are GrowUp, Hey Digital, Refine Labs, Kalungi, and Directive. GrowUp is the strongest option if search is a priority, covering both Google and AI search with a focus on pipeline and revenue. Hey Digital is a better fit when paid acquisition is the main growth lever, while Refine Labs is focused more on demand generation.
How We Built This 2026 Shortlist
If you’ve ever tried searching for a B2B SaaS digital marketing agency, you know how useless most listicles are. They rank a $20k/mo performance ads firm right next to a boutique SEO shop and a fractional CMO service, leaving you to figure out who actually does what.
When you’re scaling past Series A, you don’t have time to sort through generic agency fluff. You usually have one clear growth bottleneck, whether that’s fixing your organic footprint or scaling paid ads, and a board watching your CAC.
To make this list actually worth your time, we grouped the top agencies by the exact job you’re hiring them to do:
- Holistic SEO & AI Search: For building a long-term organic engine across Google and AI platforms like ChatGPT and Perplexity.
- Paid Media & PPC: For driving fast, creative-led trial and demo volume through ad spend.
- Demand Generation: For category building, thought leadership, and capturing dark social.
- Full-Service / Fractional CMO: For teams that need a top-to-bottom marketing department without hiring in-house executives.
Here’s how the top options stack up for 2026.

1. GrowUp
Best For: Series A through enterprise SaaS companies with complex, high-ACV products that need organic and AI search closely tied to pipeline and revenue.
GrowUp works with funded, growth-stage SaaS companies that need search to perform as a measurable revenue channel. Instead of the 12-month roadmap a bigger, slower-moving agency might propose, the engagement is structured as fast, revenue-mapped sprints, giving growth-stage teams clear channel validation and pipeline impact to present at board meetings.
The engagement typically develops across three stages:
| Phase | What We Do | What You See |
|---|---|---|
| Months 0–1 Foundation & Attribution |
Set the baseline. We wire up AttributeIQ so every piece of content and every search touchpoint can be tied back to real revenue in your CRM. From there, we audit your presence across Google and AI engines (ChatGPT, Perplexity, Claude) to find the biggest visibility gaps and commercial opportunities. | Clear sight of your technical SEO gaps and AI blind spots, plus a prioritised sprint roadmap focused strictly on pipeline revenue. |
| Months 2–5 Commercial Sprints |
Capture immediate intent. We execute rapid sprints to build competitor comparison hubs, product solution pages, and technical site updates while securing the digital PR mentions LLMs use as trust signals. | Keyword movement on Google, rising AI citation volume in your category, and content actively assisting open CRM deals. |
| Month 6+ Compound & Scale |
Expand and optimise. We expand into adjacent use cases and commercial topics, refresh pages as search behaviour changes, and improve conversion paths from first visit through trial or demo. | Trackable, multi-surface pipeline in your CRM, a declining customer acquisition cost (CAC), and a compounding search moat. |
Case Study Snapshot:
When this AI project management platform partnered with us, organic traffic was up, but it wasn’t translating into sales-qualified pipeline or demo bookings. When we ran a dual SEO and AI search audit across their digital footprint, we found plenty of broad top-of-funnel content, but a shortage of the comparison, ROI, and technical implementation pages serious buyers research before buying.
We rebuilt the content strategy around those commercial gaps, consolidating underperforming content and prioritising the pages buyers needed to evaluate the product and move toward a purchase. Nine months later, monthly demos had gone from 23 to 64, content had influenced $4.7M in pipeline, and the sales cycle had dropped from 87 to 64 days.
Pricing:
SEO programmes start at £3,000/month for ongoing advisory and £5,500/month for fully managed execution. Fully managed engagements start with a 3-month minimum, then move to rolling monthly. View investment options.
Pros:
- AttributeIQ access (£149/month value) is included throughout the engagement. Every client gets full access to GrowUp’s revenue attribution platform as part of the programme, at no additional cost.
- Senior-level access throughout. Senior strategists remain directly involved from initial strategy through execution and reporting.
- Flexible month-to-month engagement. No annual contract or fixed commitment. Scope can increase or decrease as pipeline priorities change.
Cons:
- Not a full-service growth agency. Paid media, social and PR aren’t part of the core engagement, so you’ll need other specialists if you want everything managed under one roof.
- Higher minimum engagement. With programmes starting at £3,000 per month, GrowUp may not be the right fit for companies with limited budgets or those looking for a smaller-scale SEO engagement.

2. Hey Digital
Best For: SaaS companies looking to scale demos and trials through paid media, PPC, and performance creative.
Hey Digital is a B2B SaaS digital marketing agency that specialises heavily in scaling paid acquisition. They focus strictly on performance marketing, primarily Google Ads, LinkedIn Ads, and Meta, partnered with high-converting SaaS landing page design.
They are the go-to partner for SaaS companies that have a proven organic or referral engine and are ready to pour fuel on the fire through highly targeted, conversion-focused paid campaigns.
Pricing:
Custom pricing based on ad spend and the scope of creative services required.
Pros:
- Deep specialisation in B2B SaaS paid acquisition means they understand the nuances of trial-to-paid ratios and demo-to-close metrics.
- In-house creative team designs native ad assets (video, static, GIFs) and landing pages to ensure the post-click experience actually converts.
- Strong focus on lowering Customer Acquisition Cost (CAC) while safely scaling spend.
Cons:
- Strictly focused on paid channels; they will not help you build an organic SEO moat or an overarching demand generation strategy from scratch.
3. Refine Labs
Best For: Growth-stage SaaS companies wanting to modernise demand generation and capture dark social.
Refine Labs built its reputation by challenging traditional lead-generation playbooks in B2B SaaS. They argue against gating low-intent content just to collect emails, and instead focus on “revenue R&D”, building actual demand through podcasts, LinkedIn organic, and high-impact educational content.
They are an ideal partner for Series B+ SaaS companies that want to move away from vanity metrics and optimise their entire go-to-market engine around pipeline velocity and closed-won revenue.
Pricing:
Custom pricing based on the scope of strategic advisory, execution, and revenue ops involvement.
Pros:
- Pioneers of the “dark social” tracking movement, helping you measure the un-trackable word-of-mouth growth that drives modern SaaS.
- Excellent at aligning marketing with sales, ensuring only highly qualified, high-intent accounts enter the pipeline.
- Strong thought leadership and frameworks that elevate your internal marketing team's capabilities.
Cons:
- Their methodology requires a significant shift in how leadership views marketing attribution; it may be hard to get buy-in from traditional, MQL-focused boards.
4. Kalungi
Best For: Seed-to-Series-B SaaS startups needing an entire outsourced marketing department.
Kalungi is built for early-stage B2B SaaS companies that don’t yet have a full marketing team or executive leader and need to spin up a complete marketing function immediately. They operate on a “CMO-as-a-Service” model, bringing an entire team to the table under one contract.
Their approach usually begins with establishing strategic foundations: ICP refinement, messaging, and website overhauls, before scaling into content, ABM, and paid media.
Pricing:
Custom, typically starting around $8,000/month depending on the breadth of services and fractional leadership required.
Pros:
- True full-service model. You get fractional CMO strategy, design, content creation, RevOps, and demand gen without having to hire five different agencies.
- Deep expertise in HubSpot setup and optimisation, aligning your CRM seamlessly with your marketing campaigns.
- Milestone-based, predictable scaling framework designed specifically for the venture-backed SaaS trajectory.
Cons:
- Because they handle everything, the first phase is heavily foundational; companies needing immediate inbound pipeline should expect a ramp-up period.
5. Directive
Best For: High-ACV SaaS and tech enterprises needing accountable, performance marketing at scale.
Directive (often known as Directive Consulting) is a heavy hitter in the SaaS digital marketing space, built for mid-market and enterprise tech companies. They blend paid search, paid social, and deep RevOps alignment to tie multi-channel ad spend directly to financial returns.
With proprietary frameworks like DiscoverabilityOS, they are suited for larger B2B companies that have in-house creative and content teams but need a powerhouse to manage and optimise complex, high-budget performance campaigns.
Pricing:
Custom, typically tailored for enterprise-scale budgets and complex, multi-region campaigns.
Pros:
- Unmatched accountability frameworks, tying every dollar of paid media spend directly to pipeline generation and LTV:CAC ratios.
- Deep specialist structure, capable of managing highly complex global campaigns across multiple platforms simultaneously.
- Excellent technical capabilities around RevOps and attribution for high-ACV sales cycles.
Cons:
- Can be overkill for mid-market teams. Their specialised structure requires strong internal alignment on your side to manage effectively.
How to Shortlist the Right Digital Marketing Agency for Your B2B SaaS
There is no single best digital marketing agency for every B2B SaaS company. The right choice depends entirely on your funding stage and the core bottleneck in your current growth engine.
Use the questions below to narrow the shortlist and identify the partner that fits your specific needs.
What is your funding stage and strategic growth target?
- Series A–C Growth Stage: Choose GrowUp if you need high-velocity, multi-surface organic growth (SEO + AI search) mapped directly to pipeline and CRM attribution, or Refine Labs if you need full-funnel demand creation across podcasts and social.
- Seed / Pre-Series A: Choose Kalungi if you need an outsourced CMO and execution team to build your initial marketing foundations from scratch.
Do you need to capture existing search demand or build top-of-funnel awareness?
- Capture Existing Demand: Choose GrowUp if your buyers are using Google and LLMs (ChatGPT, Perplexity) to search for high-intent solution terms, competitor alternatives, and pricing models.
- Build Top-of-Funnel Awareness: Choose Refine Labs if your product defines a new category and you need to educate buyers before they ever search for a keyword.
Fast paid traction vs. long-term compounding organic engine?
- Fast Paid Traction: Choose Hey Digital or Directive if you have ad budget ready to deploy and need immediate demo acceleration via Google Ads and LinkedIn Ads.
- Compounding Organic Engine: Choose GrowUp to build a complete organic presence across search engines and AI platforms that lowers CAC over time.
Finding the Right Digital Marketing Partner for Your B2B SaaS
The right digital marketing agency for your B2B SaaS comes down to your primary goal right now. If your main bottleneck is scaling immediate trial volume with paid ads, a performance PPC shop is the right move. If you need to build top-of-funnel awareness or create a brand-new category, a demand gen agency is the way to go.
But if your goal is building a compounding organic engine, where traditional Google SEO and AI search are tied directly to pipeline and revenue, that’s where GrowUp fits. We work specifically with Series A–C SaaS teams to capture high-intent buyers across Google, ChatGPT, and Perplexity.
