- Traditional agencies rely on wasteful percentage-of-spend models and vanity metrics, so they prioritize flat-fee, month-to-month partners focused on Net New ARR.
- SaaSHero ranks #1 with results such as $504k Net New ARR for TripMaster, an 80-day payback for TestGorilla, and flat retainers starting at $1,250 per month.

How We Ranked These B2B SaaS Growth Marketing Agencies
We evaluated more than 50 agencies using five core criteria. First, we looked at pricing transparency and alignment, comparing flat-fee retainers to percentage-of-spend models. Second, we assessed B2B SaaS specialization and depth of vertical expertise. Third, we reviewed documented case studies that included clear financial metrics, not just traffic or impressions.
Fourth, we checked whether senior experts lead execution or if work gets handed to junior account managers. Fifth, we confirmed multi-channel capabilities across Google Ads, LinkedIn Ads, and conversion rate optimization. We excluded agencies that rely on vanity metrics, require long-term contracts, or lack proven Net New ARR results in B2B SaaS.
1. SaaSHero: Best for Net New ARR Growth
SaaSHero leads this list by focusing exclusively on B2B SaaS companies in verticals such as HR Tech, Cybersecurity, and Transportation. Their flat retainer model ranges from $1,250 to $7,000 per month with month-to-month contracts, which removes the percentage-of-spend incentive to inflate ad budgets.
Their competitor conquesting strategy targets high-intent searches like “[Competitor] pricing” and “[Competitor] alternatives” with tailored landing pages. This approach attracts prospects already evaluating solutions and converts them into qualified leads. The team joins client Slack channels and shares weekly performance updates that highlight pipeline value and closed-won revenue.
Key Results:
- TripMaster: $504,758 in Net New ARR with 650% ROI and a 20% conversion rate
- TestGorilla: 80-day payback period that supported a $70M Series A raise
- Playvox: 10x decrease in Cost Per Lead with a 163% increase in lead volume
SaaSHero pricing starts at $1,250 per month for managing up to $10k in ad spend, which makes senior-level growth marketing accessible for bootstrapped startups while still scaling to enterprise needs. Their senior-led model keeps strategic oversight with experienced operators instead of junior coordinators.

2. NoGood: Strong for CRO and Experimentation
NoGood operates as an agile experimentation agency with strong conversion rate optimization capabilities. They run rapid testing cycles and build growth loops, which suit scale-ups with product-market fit that want to improve existing funnels.
Their minimum retainers usually start around $10,000 per month and often include longer contract commitments, which creates a barrier for early-stage companies. They show solid growth metrics and B2B SaaS ARR impact, yet their pricing level does not fit every budget.
Ideal for: Series A+ companies with $5M+ ARR that want focused conversion improvements and structured growth experimentation.
3. Directive: Best for RevOps-Connected Customer Generation
Directive specializes in customer generation and RevOps integration while running comprehensive paid search and paid social programs. Their main strength lies in tying marketing activities directly to pipeline outcomes through detailed attribution models.
The agency usually requires contracts of six months or longer, which can limit flexibility for some founders. They deliver ROI-linked pipeline growth and have strong B2B SaaS expertise, but their structure does not always provide the same month-to-month transparency that other agencies offer.
Ideal for: Mid-market SaaS companies with $10M to $50M ARR and complex sales cycles that need tight RevOps alignment.
For transparent pricing and month-to-month flexibility, book a discovery call with SaaSHero instead.
4. Kalungi: Fractional CMO Plus Demand Generation
Kalungi blends fractional CMO services with demand generation execution, so clients receive strategic leadership and tactical implementation in one engagement. Their full-stack support covers content marketing, paid media, and sales enablement programs.
They focus on early-stage startups and use a less transparent pricing structure, which can make budget planning difficult. They have wins with Series B growth companies, yet their generalist approach does not match the specialized competitor conquesting and CRO depth that drives immediate ARR gains.
Ideal for: Early-stage startups that need a broad marketing strategy and hands-on execution guidance from a single partner.
5. Refine Labs: Enterprise-Focused Demand Generation
Refine Labs focuses on demand generation attribution and high-intent lead capture using advanced tracking and reporting systems. Their enterprise orientation supports large deal sizes but also requires significant budget commitments.
Long-term contracts and high minimum spend limit access for growing companies. They show strong revenue metrics for enterprise clients, yet their model does not match the flexibility and cost efficiency that bootstrapped and Series A companies usually need.
Ideal for: Enterprise SaaS companies with $50M+ ARR and complex, multi-stakeholder sales processes.

Their competitor conquering playbooks and heuristic CRO process deliver quick wins while building a durable growth engine. This mix of specialization, aligned incentives, and documented outcomes makes SaaSHero a strong choice for B2B SaaS teams that care more about Net New ARR than vanity metrics.
Frequently Asked Questions: Choosing a B2B SaaS Growth Marketing Agency
What is a good CAC for B2B SaaS in 2026?
A healthy CAC for B2B SaaS usually falls between $200 and $400 for mid-market companies, with LTV to CAC ratios of at least 3:1. Enterprise products often see CAC above $5,000 because of longer sales cycles and higher deal values. The main goal is to keep payback periods under 90 days to satisfy investors and protect cash flow.
How do I avoid agency spend traps?
Select agencies that use flat-fee retainers instead of percentage-of-spend pricing. Ask for month-to-month contracts, so you keep flexibility and can enforce accountability. Prioritize agencies that report on Net New ARR, pipeline value, and SQL conversion rates instead of impressions or CTR alone. Confirm that the agency connects to your CRM for accurate attribution tracking.
What is the best agency for scaling after funding?
SaaSHero fits post-funding scaling needs with proven 80-day payback periods and case studies above $504k in Net New ARR. Their flat retainer structure supports rapid budget increases without percentage-based fee jumps. Their B2B SaaS focus also improves how budgets get allocated across Google and LinkedIn channels.
Should I prioritize month-to-month contracts over long agreements?
Month-to-month contracts align agency incentives with your success and create pressure for consistent performance. Long-term contracts protect agency revenue but can encourage complacency. For new partnerships, month-to-month terms let you validate results before committing to a longer agreement.
How important is B2B SaaS specialization in an agency?
B2B SaaS specialization matters because it shapes how an agency reads metrics like MRR, churn, and sales cycle length. Generalist agencies often misread these signals. SaaS-focused teams know how to reach decision-makers, build comparison content, and support longer consideration periods. This expertise improves lead quality and conversion rates.
