If you lead marketing or growth at a B2B SaaS company, Madx Digital has almost certainly come up in your search for an organic growth partner. Founded by Perry Steward, the agency has built a reputation for combining traditional SEO with AI search optimization (often called GEO or AEO), digital PR, content, and link building, all geared toward pipeline and revenue rather than vanity metrics. For many SaaS marketing leaders, that positioning resonates strongly.

That said, Madx represents one credible option among several specialist agencies serving the B2B SaaS category. The right partner for your business depends on factors that vary widely from company to company, including your funding stage, ICP, target geography, internal team structure, and the maturity of your existing organic search programme. An agency that thrives with a Series A scaleup in London may feel like an awkward fit for a $50M ARR enterprise SaaS based in California, and vice versa.

In this guide, you will find ten alternatives to Madx Digital that B2B SaaS companies are commonly evaluating in 2026. Each entry summarises what the agency does, who it tends to work with, and which services it offers, so you can build a shortlist that genuinely aligns with your go-to-market motion. Rather than ranking the agencies against each other, the goal here is to give you enough neutral context to make an informed choice.

How This List Was Compiled

Before diving into the agencies themselves, it helps to understand the criteria behind the selection. A list of “alternatives” only proves useful when each entry actually competes for the same kind of work and the same kind of buyer.

Every agency featured here serves B2B SaaS as a core focus, offers a service mix that overlaps meaningfully with Madx Digital across SEO, AI search optimization, content, and link building or digital PR, and demonstrates a track record with growth-stage and mid-market or enterprise SaaS clients through public case studies, named client lists, or third-party reviews on platforms such as Clutch and G2. Beyond the first entry, the agencies appear in no particular order. You should evaluate each one against your own ICP, internal capabilities, and commercial objectives rather than treating the sequence as a ranking.

The 10 Best Madx Digital Alternatives

With the criteria established, you can move into the shortlist itself. Each profile below outlines what the agency does, the kind of SaaS company it tends to suit, and the services it brings to the table.

1. Platypus SEO

Platypus SEO focuses exclusively on helping European B2B SaaS companies translate organic search into revenue-aligned outcomes such as qualified pipeline, demos, and free trials. Rather than functioning as a detached vendor, the agency integrates deeply with internal marketing and growth teams and takes strategic ownership of campaign initiatives and results.

Its core offering combines traditional SEO across Google, Bing, and DuckDuckGo with AI search optimization for surfaces such as Google AI Mode and ChatGPT, reinforced by content marketing, CRO, and link building from high-quality, relevant websites. 

Platypus primarily serves growth-stage B2B SaaS companies generating around $5M+ ARR, selling to mid-market or enterprise buyers, and operating in competitive categories. It also engages selectively with earlier-stage SaaS or B2B technology companies that demonstrate clear go-to-market focus. For European SaaS leaders who want a partner rather than an outsourced execution arm, the model offers a recognisable fit.

2. Omniscient Digital

When SaaS marketing leaders look for a partner that ties SEO, GEO, and content tightly to pipeline, Omniscient Digital frequently appears on the shortlist. Its leadership team has held in-house roles at HubSpot, Shopify, and Workato, and the agency has worked with brands including Jasper, Adobe, SAP, Asana, Loom, and Hotjar.

Engagements anchor on its OmniscientX research framework and a “barbell” content strategy, balancing editorial-led authority content with conversion-focused product and bottom-of-funnel pages. Reporting connects organic performance back to qualified leads, pipeline, and ARR.

3. Skale

For funded SaaS companies that want SEO measured in MRR, signups, and CAC payback rather than rankings alone, Skale offers a model built specifically around those metrics, working exclusively with SaaS clients.

Headquartered in London with a distributed team, Skale assigns pod-based delivery groups covering SEO strategy, content, technical SEO, and off-page work. Reporting revolves around SaaS-specific KPIs rather than impressions or sessions alone. The agency has worked with brands including ActiveCampaign, Hotjar, TestGorilla, Slite, and Recruitee, and it offers international SEO support for SaaS companies expanding across English- and Spanish-speaking markets and other European territories.

4. Powered by Search

Mid-market and enterprise B2B SaaS companies with high average contract values, long sales cycles, and multi-stakeholder buying committees often gravitate toward Powered by Search, which has supported B2B software and technology companies since 2009.

Rather than treating SEO as an isolated channel, the agency integrates it with paid media, ABM, content, and revenue operations through its Predictable Growth methodology, mapping content strategy to multiple stakeholders across the buying committee. The team has also developed its RAISE framework for Answer Engine Optimization, helping clients appear across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Notable clients include Basecamp, SentinelOne, and Fortra.

5. Directive Consulting

SaaS marketing leaders who want SEO integrated with paid media, RevOps, and rigorous financial modelling often consider Directive Consulting, a global performance marketing firm built specifically for B2B software and technology brands.

Directive’s proprietary “Customer Generation” methodology aligns marketing programmes around CAC, LTV, and qualified pipeline rather than top-of-funnel volume metrics. Within that framework, SEO sits alongside paid media, CRO, design, video, and revenue operations as part of a unified programme. Headquartered in Irvine, California, the agency has worked with brands including ZoomInfo, Sumo Logic, Cisco Meraki, SentinelOne, and Adobe.

6. Grow and Convert

B2B SaaS companies that want SEO content tied directly to trial signups and demo requests, rather than traffic for its own sake, often look at Grow and Convert, founded by Benji Hyam and Devesh Khanal more than a decade ago.

The agency coined the term “Pain Point SEO,” a methodology that prioritises high-intent, bottom-of-funnel keywords most likely to drive trials and demo requests over high-volume informational terms. Engagements typically combine content strategy, in-depth article production based on subject-matter expert interviews, link building, and attribution tutorials, while content frameworks increasingly incorporate prioritised GEO for AI-generated search results.

7. Animalz

When the brief leans toward long-form thought leadership and editorial-quality content rather than pure SEO mechanics, Animalz tends to enter the conversation, having supported some of the most recognisable names in B2B software for nearly a decade.

Animalz launched in 2015 in New York and now operates as a remote, global team providing content strategy and creation for B2B SaaS, technology companies, and venture capital firms. The agency emphasises editorial quality, original thinking, and thought leadership content built around real subject-matter expertise, with services spanning long-form SEO content, AEO, LinkedIn content, and integrated campaigns. Clients include Google, Intercom, Zendesk, Amplitude, GoDaddy, and Retool.

8. Omnius

B2B SaaS and fintech scaleups looking for an integrated SEO and AI visibility partner with regional context often evaluate Omnius, which narrows its focus to a small set of verticals and emphasises depth over breadth.

Omnius works almost exclusively with SaaS and fintech companies, supporting startups and scaleups across Europe and beyond. The agency optimises B2B websites both for traditional search engines and for visibility inside LLM-generated answers, combining technical SEO, content cluster development, programmatic SEO, and AI visibility work. Reported engagements span publicly listed enterprise SaaS, fintech scaleups across the UK and EU, and high-growth startups.

9. Breaking B2B

SaaS leaders who prefer a founder-led, lean specialist team over a larger retainer-driven agency frequently consider Breaking B2B, led by founder Sam Dunning.

The agency works primarily with B2B SaaS, technology, fintech, logistics, and professional services companies. Its engagement model centres on founder-led strategy and a tight specialist team, and its five-step process begins with deep ICP work before any content strategy gets developed. Core services span technical SEO, content, link building, and digital PR, with web design and development integrated where clients need site architecture and SEO delivered together. AI search and GEO strategy come included in higher-tier plans.

10. First Page Sage

B2B SaaS, professional services, and technology companies investing in long-horizon thought leadership SEO and brand authority often look at First Page Sage, which has cultivated a distinct positioning over a long operating history.

First Page Sage has operated since 2009 under founder Evan Bailyn and specialises in “thought leadership SEO,” pairing subject-matter experts with client executives to produce content published under named bylines. Engagements typically run on twelve- to twenty-four-month investment horizons rather than quick-win timeframes, and the agency was one of the earliest to popularise SEO ROI modelling, projecting campaign value based on customer lifetime value and close rates.

How to Choose the Right Madx Digital Alternative

No two B2B SaaS companies share an identical organic growth profile, even when they look similar from the outside. Every agency above serves B2B SaaS, yet each one specialises in a different stage, motion, and part of the funnel. To narrow your shortlist, work through the following questions before booking discovery calls.

Start with your stage. Earlier-stage startups, growth-stage scaleups, and enterprise SaaS organisations typically benefit from different agency profiles, levels of seniority, and reporting cadences, so an agency built for $50M+ ARR clients rarely fits a Seed-stage operation, and the reverse holds equally true. Next, think about where your audience actually searches today. If platforms such as ChatGPT, Perplexity, and Google AI Mode now influence your buying cycle, prioritise agencies with a structured GEO or AEO offering rather than a bolted-on AI module.

From there, consider which part of the funnel needs the most attention. Some agencies excel at top-of-funnel authority and demand creation, while others lean into bottom-of-funnel, conversion-focused content and category pages. Closely related, ask whether you need a single channel partner or a multi-channel one. Several agencies on this list include paid media, ABM, RevOps, or web design alongside SEO, whereas others remain pure-play SEO and content specialists.

Geography also matters more than many shortlists assume. European-focused agencies and US-focused agencies often differ noticeably in language depth, local link building networks, and time zone alignment, all of which affect day-to-day collaboration. Finally, weigh the maturity of your internal marketing team. Lean teams generally benefit from a more embedded, full-service partner that can take strategic ownership, while well-resourced teams may prefer a specialist that complements specific gaps without trying to take over.

Once you have clear answers to those questions, the agencies above become much easier to evaluate on genuine fit rather than surface-level positioning.

Final Thoughts

Madx Digital remains a strong option for many B2B SaaS companies, yet it is far from the only credible choice. The ten alternatives covered here represent a cross-section of the most established specialist organic growth and SEO agencies serving B2B SaaS in 2026, ranging from European-focused boutiques to global, multi-channel performance marketing firms. Each one brings a distinct point of view and a recognisable set of strengths.

Your right partner ultimately depends on your stage, ICP, target geography, and how integrated organic search needs to be with the rest of your go-to-market motion. Treat this list as a starting point for vendor evaluation rather than a final ranking, and request case studies, client references, and tailored proposals that map clearly to your own pipeline and revenue goals before you commit. The agencies that engage seriously with those questions, rather than defaulting to generic decks, generally end up being the ones worth a longer conversation.
