A digital growth marketing agency runs digital channels, including SEO, content, paid media, and answer engine optimization (AEO), as one system built to generate qualified pipeline and revenue, instead of as separate tactics judged by impressions, traffic, or rankings alone.
Most marketing vice presidents have lived the alternative: twelve months of retainer spend, a monthly report full of traffic trends and keyword rankings, and a chief financial officer asking why none of it shows up in the pipeline numbers. The agency delivered what it promised. It just promised the wrong thing.
The evaluation criterion most agency comparison guides skip is the one that counts most: How does this agency define success? Traffic is easy to grow. Pipeline attribution is harder, and most agencies never commit to it.
If you're sorting through digital growth marketing agencies, this guide covers six that connect their work to pipeline and revenue beyond reach. After reading, you'll be able to identify which agencies report on business outcomes, which operating model fits your stage and budget, and which two or three are worth taking to a discovery call.
*Disclosure: Ten Speed wrote this guide and is one of the six agencies listed. We represent each agency using what its own public pages state. For an independent cross-check, check out G2's B2B marketing agency category.
Key takeaways
- The sharpest dividing line across digital growth marketing agencies is whether they report on pipeline and revenue or on traffic and rankings.
- An agency's operating model, organic-led, paid-led, or full-service, determines which parts of the pipeline it can influence and what it will report.
- Pipeline results on agency sites are mostly self-reported, so ask every agency for CRM-level detail behind the outcomes it states.
- Few agencies publish pricing, so ask for scope and minimums before the first call.
- AI search is changing where buyer preference forms, so ask each agency how it tracks visibility in answer engines.
How we chose these six agencies
Each agency on this list publicly ties its work to pipeline or revenue, serves B2B SaaS or B2B tech, and publishes its own description of its services and outcomes. The six were also chosen to represent different operating models: organic-led, paid-led, and full-service, so you can compare across approaches rather than within one.
We excluded agencies that reported only traffic or ranking improvements without connecting those outcomes to pipeline. If you want a broader look at agencies across inbound channels, this guide to inbound marketing agencies covers more ground.
On evidence: Every claim in this article comes from the agency's own pages. Results an agency reports about itself are labeled "agency-stated," and where a page doesn't document a claim, we say so. We last verified all entries on October 26, 2026, but pricing, service scope, and positioning can change.
Agencies compared by operating model and reported outcome
The six agencies below split most clearly by operating model, which determines which pipeline stages each can influence and what it can credibly report. Use this table to find the row that matches your stage, budget, and primary outcome, then read that agency's full entry.
The sharpest dividing line across these agencies is whether their stated primary outcome is a business metric (pipeline, revenue, MRR) or a channel metric (traffic, rankings, link count). Neither framing is inherently wrong for every buyer, but the distinction counts when you're justifying spend internally.
An agency that reports organic sessions can’t tell your CFO what those sessions produced. That weakness is worth pressure-testing before you sign anything, and competitor comparison content is one of the clearest signals of whether an agency thinks in terms of pipeline or only visibility.
One more dimension belongs in your evaluation now: Whether the agency measures and builds for AI answer engines. G2's March 2026 survey of B2B software buyers found 51% of participants start with an AI chatbot more often than Google. If your agency can't report on that surface, you're missing where a growing share of your buyers begin their search. The difference between AEO and SEO is worth understanding before you finalize your shortlist.
1. Ten Speed
Ten Speed fits B2B teams that want SEO, content, AEO, and digital PR managed together as one organic growth program, with outcomes reported in pipeline and revenue terms. We don’t run paid advertising or build websites, so our services work best alongside a separate paid media or web partner rather than as a full marketing department replacement.
Our Bitly engagement illustrates what that model produces in practice. Ten Speed's work with Bitly delivered +29% average MRR and +19% premium subscriptions. On the AEO side, Ten Speed's AI Brand Audit maps how AI models describe and reference a brand relative to competitors, then informs content planning and tracks AI referral traffic over time.
Co-founder and CEO Nate Turner spent more than eight years at Sprout Social, where he helped build the inbound engine and marketing team behind its growth from $100K to $100M in annual recurring revenue. That operator background shapes how engagements run: Strategy and execution stay aligned under the same team rather than getting handed off between departments.

2. Directive Consulting
Directive Consulting fits B2B SaaS and tech teams that want paid media, SEO and content, CRO, and lifecycle marketing managed together under one pipeline-reporting model.
Directive describes itself as a performance marketing agency for B2B companies with 420+ B2B brands served, three divisions (Performance, Communications, and Commerce), a remote-first team, and an office in Irvine, California.
It operates under a proprietary Customer Generation methodology, positioning the agency as a revenue partner rather than a channel vendor. That framing ties organic and paid programs to a shared pipeline metric rather than reporting each channel in isolation. Paid media sits at the center of how that model works, and the pages we reviewed document no minimum spend.
If you're evaluating Directive alongside other options, our best SEO services guide covers how channel scope and reporting models differ across agencies.
3. Omniscient Digital
Omniscient Digital fits B2B software brands that want SEO and GEO tied to pipeline.
Omniscient is an organic growth agency that helps B2B software businesses turn SEO, GEO, and content into growth channels. Its services include SEO strategy, programmatic SEO, technical SEO, content production, digital PR, and analytics, and it describes SEO and GEO strategies fueled by content and tied to leads, pipeline, and revenue.
(If you’re wondering how GEO compares to AEO, the mechanics overlap but the framing differs. This breakdown on AEO is a great place to start.)
4. Refine Labs
Refine Labs fits B2B teams that want demand creation and capture tied to meetings and revenue instead of traditional lead generation.
It’s a B2B demand generation agency that has worked with almost 300 B2B companies in five years, with creative campaign work that builds demand, captures in-market buyers, and converts interest into meetings and revenue.
The pages we reviewed describe demand generation and brand strategy and name no organic search or AEO service. If your primary goal is a demand-creation program with pipeline as the reporting currency, Refine Labs is worth evaluating. If organic growth is central to your strategy, learn how Ten Speed supports product-led growth (PLG) SaaS teams on the organic side.
5. Kalungi
Kalungi fits B2B SaaS companies that need a full outsourced marketing department rather than a specialized channel partner.
Kalungi describes itself as a full-stack B2B SaaS marketing team led by an experienced CMO, says it serves more than 100 B2B SaaS companies, and states that a typical full-service engagement starts at $45,000 per month. Kalungi's CPGvision case study reports that it sourced $4.7 million in pipeline. Both figures are agency-stated.
Kalungi says its playbooks work best for B2B SaaS companies, so businesses outside that vertical aren't its target.
6. Walker Sands
Walker Sands fits established B2B companies that want PR and integrated marketing running in one program instead of handed off between separate vendors. It’s a full-service B2B integrated marketing and public relations agency founded in 2001 that follows an outcome-based marketing approach.
Its capabilities span strategic communications (PR, media relations, social media), digital marketing (paid media, SEO, generative engine optimization, marketing automation), content (content strategy, original research, editorial content, sales enablement), creative, and revenue operations (CRM implementation, RevOps, HubSpot and Clay configuration).
The agency calls its operating philosophy Outcome-based Marketing, which it describes as working backward from business objectives rather than leading with a channel mix.
How to shortlist from here
Whichever agencies you bring into discovery calls, use the same three filters: what business outcome they report on, what evidence they can show for it, and whether their operating model adds capacity to your team or creates more coordination overhead. Those filters will cut the list faster than any capability matrix.
If organic search, AEO, and content are the channels you need to make work, Ten Speed operates as an embedded growth partner rather than a vendor managing deliverables at arm's length. Ten Speed says it has helped B2B clients generate over $50 million in additional organic revenue.
If that model fits where your team is right now, talk to our team about your organic growth goals.
Choose the agency that answers for pipeline, not traffic
The six agencies split by operating model (organic-led, paid-led, or full-service), and the model you pick determines which parts of the pipeline you can hold an agency accountable for. Shortlist two or three that match your stage and budget, then ask each the same three questions on the discovery call: what customer relationship management (CRM)-level detail sits behind the outcomes you report, what your scope, minimums, and contract terms are in writing, and how you track visibility in answer engines and what baseline you start from.
If you want organic search and AEO reported against revenue, and you already have or plan to add a separate partner for paid media, Ten Speed is built for that setup. Start with a conversation about how your organic program would be measured against pipeline.
Frequently asked questions
How do I know if my company is ready to hire a digital growth marketing agency versus building in-house?
A digital growth marketing agency makes sense when you have at least one in-house marketer who can own the relationship, a defined ICP, and the ability to share CRM data so results can be tied to pipeline. Building in-house becomes more viable when you need a full marketing department rather than a strategic extension of your team. Companies still finding product-market fit are usually better served getting internal clarity before bringing in an agency.
What does it mean for an agency to measure pipeline instead of traffic?
It means the agency reports outcomes your sales team recognizes, such as pipeline created, pipeline influenced, win rate, and customer acquisition cost, using data from your CRM, not only sessions, rankings, or leads. Ask each agency to show a sample report and to explain how it attributes opportunities to channels. Attribution is imperfect for any channel, so the better question is whether the agency is honest about what it can and cannot connect to revenue.
Should I choose an organic-led, paid-led, or full-service agency?
Choose by what you need to influence. Organic-led agencies build compounding search and AI visibility but take longer to show results. Paid-led agencies can create pipeline faster but stop when spending stops. Full-service agencies run both under one reporting model but cost more and spread attention across channels. Many B2B teams pair an organic-led partner with a separate paid partner.
How much does a digital growth marketing agency cost?
Costs vary widely, and most agencies on this list don't publish rates. Kalungi is an exception: Its site says a typical full-service engagement starts at $45,000 per month. Ask each agency for scope, minimums, and contract terms in writing before comparing.
Can one agency handle both SEO and AI visibility, or do I need separate partners?
Often one agency can. Google's documentation says there are no additional requirements or special optimizations for appearing in AI Overviews and AI Mode, and that SEO best practices remain relevant. The deciding factor is whether an agency tracks AI visibility with a defined process and reports on it separately, so ask each agency how it measures mentions and citations across answer engines and what baseline it starts from.
