Growth marketing has become a central lever for SaaS companies in the scaling phase. Acquisition, activation, retention, revenue: the promise is clear, but not all agencies are equal, especially in B2B.
In this article, we've selected 5 of the most well-known and recognized growth marketing agencies, comparing them based on their specialization, approach, and fit with modern SaaS challenges.
1. Growth Room: The Full-Funnel Pipeline-Driven Agency for B2B SaaS
Positioning: SaaS (strong B2B focus), revenue and pipeline-driven growth
Location: France / Europe (Paris-based agency)
Growth Room presents itself as a performance-focused growth marketing agency with strategies designed to generate acquisition and, above all, sustainably fuel the pipeline. The agency emphasizes an organization by expertise (Ads, SEO, Sales Ops, RevOps) to cover multiple levers without losing the "revenue" thread.
What Growth Room Does Concretely
According to its positioning, Growth Room structures its offering around several building blocks useful for B2B SaaS in the scaling phase:
- Ads (campaign management)
- Growth Outbound (digital prospecting and lead generation processes for sales teams)
- SEO (with an announced "SEO & AI" focus)
- ABM, RevOps and HubSpot support
- A team positioned as mostly senior and specialized by verticals
Why Growth Room is #1 in This Ranking
- Full-funnel approach, but execution-oriented: the agency focuses on activating the right acquisition levers to reach measurable objectives
- Clear bridge between marketing and sales: the "Growth Outbound" offering is explicitly designed to send qualified leads to sales teams through a structured process
- Stack and execution compatible with RevOps challenges (Ads, SEO, Sales Ops, RevOps): useful when the issue is no longer "generating traffic" but industrializing the pipeline
- SaaS credibility: Growth Room states it has supported over 100 SaaS clients
Ideal for You If…
- You're a B2B SaaS from Seed to Series B/C and your priority is to accelerate one or several channels without breaking revenue alignment
- You have a sales team in place and you're looking for an agency that knows how to operate with pipeline constraints (qualification, handover, process)
Growth Room has established itself in recent years as the reference agency for fast-growing B2B SaaS. Their strength: a very business-impact oriented approach, far from vanity metrics.
Growth Room also stands out for its deep understanding of Sales × Marketing challenges, which explains their partnership with Zeliq, a Sales Intelligence tool focused on commercial performance.
2. Growth Tribe: The Growth Marketing Pioneer
Positioning: Growth culture, training, transformation
Location: International
Growth Tribe is one of the historic players in growth marketing. Very well known for its training programs and methodology, the agency has largely contributed to popularizing growth in Europe.
Growth Tribe's Strengths
- Strong international reputation
- Very structured experimentation approach
- Excellent at upskilling internal teams
Growth Tribe's Limitations
- Less focused on long-term execution
- Business impact sometimes indirect for B2B SaaS
Growth Tribe will be perfect for teams looking to structure a growth culture internally.
3. Eskimoz: The SEO Leader Focused on Scale
Positioning: SEO, organic acquisition, content
Location: Europe
Eskimoz is an undisputed reference in SEO and organic growth, with a strong presence in the tech and SaaS ecosystem.
Strengths
- Very strong SEO expertise
- Ability to scale internationally
- Solid and proven methodologies
Limitations
- Less cross-functional than full growth agencies
- Not sales / revenue ops oriented
Less versatile than the first two players, Eskimoz remains an SEO reference, making it an essential player if this channel is by far the most important.
4. NoGood: The US Performance-Oriented Reference
Positioning: Paid media, experimentation, brand × performance
Location: United States / International
NoGood is one of the best-known growth agencies in the United States. It works with iconic brands and combines performance marketing and branding.
Strengths
- Very strong paid & experimentation expertise
- Premium image
- Very advanced data-driven approach
Limitations
- Not specialized in B2B SaaS
- Budget often high for European scale-ups
Despite a lack of B2B SaaS specialization, NoGood is a leader in the US. Recommended for companies with substantial budgets looking to expand massively in the US to make it their main market.
5. Skale: The SEO Expert for International SaaS
Positioning: SaaS SEO, organic growth
Location: International
Skale has established itself as an SEO reference for international B2B SaaS, with a very revenue-oriented, long-term approach.
Strengths
- Ultra-specialization in SaaS
- ARR-oriented SEO method
- Very good results in competitive markets
Limitations
- Scope deliberately limited to SEO
- Less suited for multi-channel strategy
Similar to Eskimoz, Skale will be ideal for SaaS companies where SEO is at the heart of all discussions, especially if the ambition is international.
