10 Best Kalungi Alternatives in 2026

Choosing a marketing partner rarely comes down to one “best” agency. It comes down to fit. If Kalungi sits on your shortlist, you already know it carries a strong reputation in B2B SaaS, so the real question isn’t whether another agency beats it. The question is which partner matches your stage, your priority channel, and the region you sell into.

This guide compares ten agencies you can run instead of, or alongside, Kalungi. Rather than ranking them one to ten by quality, we’ve mapped each one to the situation where it performs best. That way, you match an agency to the channel you most need to own and skip the ones built for a different job. 

TL;DR: which agencies are a suitable alternative to Kalungi?

Short on time? Here’s the quick version before we dig into the detail.

If you run B2B SaaS product and want to own organic and AI search as a genuine revenue channel then Platypus SEO makes the most direct specialist alternative. Need breadth across many channels at enterprise scale? Larger generalists like Brainlabs and Seer Interactive earn a look. Chasing authority and earned coverage instead? Digital-PR-led shops fit better. In other words, your stage and your priority channel decide the answer, not a leaderboard.

What does Kalungi do, and where does it fit?

Before you weigh up alternatives, it helps to pin down what Kalungi actually offers and the kind of company it suits.

Kalungi runs as a full-service B2B SaaS marketing agency. Instead of handing you a single channel, they agency gives you a fractional CMO plus a supporting team across strategy, content, demand generation, and paid media. The model leans on the T2D3 framework, a well-known map for scaling SaaS revenue through predictable ARR milestones. So if you lack senior marketing leadership and want someone to own the entire function, Kalungi fills that gap neatly.

That breadth suits some teams beautifully. For when you already have leadership in place though, or you want one channel run exceptionally well, a full marketing department can feel like more than you need. Building an organic programme that maps to revenue calls for a different kind of partner, one that goes deep rather than wide.

With that anchor set, let’s look at why so many SaaS teams start searching for something different.

How to evaluate a Kalungi alternative

Once you start comparing agencies, the marketing pages blur together. A short checklist keeps you honest and makes shortlisting far quicker. Run every candidate through these six questions.

• Specialism versus breadth. Do they specialise, or cover everything for everyone?
• Channel ownership. Will they own organic, AI search, paid, and ABM, or just one slice? If AI matters, ask how they approach answer engine optimisation.
• Stage fit. Which ARR band and funding stage do they genuinely deliver for?
• Proof type. Do they report pipeline and revenue, or traffic and rankings?
• Engagement model. How flexible is the retainer, and who handles the day-to-day work?

One neutral tip before you brief anyone: take a clear-eyed look at where your site stands today and map your priority keywords to real buyer intent. The sharper your own picture, the easier it becomes to judge whether an agency’s plan holds up.

With those six questions in hand, here’s how the ten agencies stack up.

Our pick: the 10 best Kalungi alternatives

The table below summarises each agency by ideal use case, specialism, region, and whether AI search sits in its toolkit. Treat it as a map rather than a verdict, because the detail underneath explains the nuance.

Positioning shifts over time, so confirm the finer points on each agency’s own site before you reach out. Now for the detail.

1. Platypus SEO

Best for: European B2B SaaS at Series A or B that wants a revenue-aligned organic and AI search partner, not a full marketing department.

Platypus SEO does one thing, and does it deliberately. It grows organic and AI search for European B2B SaaS companies, and it ties that growth to revenue, qualified pipeline, demos, and free trials, rather than traffic for its own sake. Crucially, it treats SEO, AI search optimisation, content, and CRO as one coordinated system instead of four separate line items.

The model matters as much as the method. Platypus plugs in as an extension of your in-house team and takes strategic ownership of the channel, which makes it a strong fit when you already have leadership and want a specialist to run search end to end. Its core B2B SaaS SEO offer pairs intent-mapped keyword work, technical fixes, and funnel-tied content with a three-month strategy and a twelve-month roadmap, while the AI search side builds brand mentions across industry listicles and communities and earns the reviews that engines lean on.

You can see how the team structures an engagement and browse documented client outcomes, including a 330% lift in monthly signups for a field-service platform and a 300% SEO return inside six months.

2. Brainlabs

Best for: enterprises that want multi-channel marketing managed in one place.

Brainlabs runs as a large, global, data-led media agency, so you get serious breadth under one roof: paid search, programmatic, paid social, retail media, influencer, creative, analytics, and CRO, with a substantial SEO practice covering technical, on-site, off-site, and content work. 

Experimentation sits at the centre of how they operate. They test relentlessly and lean on proprietary tooling to scale what works. They’ve also moved early into AI search, building visibility across platforms from Google and YouTube to Reddit. 

3. Seer Interactive

Best for: data-mature mid-market and enterprise brands. 

Seer Interactive built its name on a “big data” approach to organic and paid search, blending large-scale audience research with analytics to decide where to focus. Expect rigour and transparency: the team publishes its own studies and test results rather than guarding them, which tells you plenty about how it works. 

Alongside SEO, paid media, analytics, and CRO, it has invested heavily in generative engine optimisation, running dedicated AI research the wider industry cites. You’ll get the most from this partnership if your own team can act on detailed, data-rich insight. 

4. NP Digital

Best for: companies that want a well-known generalist with global coverage. 

NP Digital takes a broad, multi-channel stance across paid and organic search, social, influencer, content, performance display, email, and CRO, and it backs that with a stack of proprietary tools and a data-driven, consultative style. 

It works globally with enterprise and mid-market “challenger” brands across many industries, so you gain reach, recognisable expertise, and a partner comfortable running several channels at once. The flip side of that breadth is that SEO sits as one service among many rather than the whole focus. 

5. iPullRank

Best for: teams wrestling with thorny technical or architectural challenges. 

iPullRank goes deep where others stay shallow: technical SEO and content engineering on large, complex sites, increasingly extended into machine learning, generative AI, and “relevance engineering” for AI search. 

The team partners mostly with enterprise and mid-market companies, and it’s the kind of shop other agencies call when a problem gets genuinely hard.

6. Aira 

Best for: European brands that want digital PR and links alongside SEO. 

Aira pairs SEO with award-winning digital PR and link building, then rounds out the offer with paid media, content, CRO, and CRM and analytics work, so search rarely sits in a silo. The team takes a goals-first, channel-agnostic stance: it’ll flex budget between services and tell you plainly when a channel isn’t the right investment. 

Based in the UK but working flexibly with clients across Europe and beyond, it suits brands that want authority and earned coverage building in parallel with rankings. 

7. Go Fish Digital

Best for: brands where PR, reputation, and search pull together. 

Go Fish Digital lives where search and reputation overlap. Alongside SEO, content, and paid media, it offers strong digital PR, online reputation management, and web development, which is useful when what people find about you matters as much as where you rank. 

The team leans on proprietary, AI-powered tooling to speed up research and to track how brands surface in tools like ChatGPT, and it has built dedicated SEO and GEO products. It now sits within the wider Agital group, which extends the services you can reach through one relationship. 

8. Single Grain

Best for: companies that want growth marketing built around a strong search core. 

Single Grain runs as a full-funnel growth agency that ties its work to revenue rather than vanity traffic. Think pipeline, CAC, and LTV across SEO, paid media, content, performance creative, CRO, and analytics. 

The agency carries real depth in SaaS, technology, and ecommerce, and it positions itself as AI-forward, running programmatic SEO and “Search Everywhere Optimisation” across engines, social platforms, and AI assistants. With a founder who’s a well-known marketing voice, the agency stays close to what’s shifting in search. 

9. Salt.agency

Best for: brands scaling across markets and languages, or untangling complex technical issues. 

Salt.agency is a bespoke technical SEO specialist, and technical depth genuinely sits at its core: international and multilingual SEO, site migrations, enterprise local SEO, ecommerce platforms like Shopify and Magento, penalty recovery, and organic-traffic-drop audits, increasingly extended into AI and LLM visibility. 

With teams in the UK and the US serving brands worldwide, it’s well suited to multi-region search. The team embeds as an extension of your own, working closely with your developers and stakeholders rather than handing over an audit and disappearing. 

10. Rise at Seven

Best for: brands chasing headline-grabbing PR that also moves search. 

Rise at Seven is a “search-first” creative agency that fuses SEO with bold, often viral digital PR and creative campaigns, plus social search, content, and ecommerce and international SEO. The pitch is rankings and cultural relevance together. 

The team deliberately “chases consumers, not algorithms” to earn coverage that travels and links that move the needle. With offices across the UK and in New York, it leans toward retail, fashion, travel, and ecommerce, and it has the awards shelf to match. 

How to choose the right alternative for your stage

Your stage and your priority channel point you straight to a shortlist. Use this quick mapping to narrow things down today.

• Want to own organic and AI search as a revenue channel, and you sell B2B SaaS in Europe? Start with Platypus SEO.
• Need many channels coordinated at enterprise scale? Look at Brainlabs or Seer Interactive.
• Facing a complex technical or international site? iPullRank and salt.agency fit well.
• Chasing authority through earned coverage? Aira, Go Fish Digital, or Rise at Seven.
• After a broad generalist or founder-led growth? NP Digital or Single Grain.

Whatever your stage, the principle holds: pick the partner whose speciality matches the channel you most need to own.

The bottom line

Kalungi remains a strong choice for the stage it serves, particularly SaaS teams that need a full marketing function and a proven framework to follow. But if you’ve already got leadership in place, and you want organic and AI search run as a measurable revenue channel, a specialist serves you better.When you’re ready to test the fit, start a conversation with the team and see how the plan maps to your own pipeline.
