A SaaS ABM agency is a specialized marketing partner that helps software companies win ICP-fit accounts by running highly personalized campaigns for specific accounts instead of broad audiences.

Some of the best SaaS ABM agencies are listed in the graphic below:
When choosing the best ABM firm for your SaaS business, you should consider the agency’s:
Industry experience, results and clients they’ve worked with, especially the account managers/operators who will be running your account.
Overall ABM approach and service lines that they offer.
ABM tech stack and how they are using it (If I were you, I’d ask them to show you sample workflows).
Alignment with your GTM team: How exactly are they going to work alongside your sales reps?
Their approach to personalization and testing (do not overlook this).
Cost structure, contract flexibility and the length of the proposed contract.
For this guide, I’ve prepared a comprehensive list of the 10 best SaaS ABM agencies in 2025 that can help you scale your GTM motion with an account-focused growth strategy.

#1: Restartt
Restartt is a SaaS ABM agency that designs and runs account-based programs with signal-based outbound.
We help you set up the right signals (not just going after signals that everyone else is running), create the right touchpoints, and then orchestrate & refine.
What makes Restartt the best ABM SaaS agency on the market is that:
You’ll be working directly with the founders, John Ozuysal & George Chasiotis, who have built and scaled VC-backed start-ups and marketing agencies with ABM, and have worked with 100+ SaaS companies combined.
You can start with lean ABM without having to invest in a 6-figure ABM tech stack and without being a Fortune 500 company. We use a combination of our internal tools that we’ve built for ABM, free-forever tools, paid tools, and our network of ABM software partners like Warmly.
We believe that you can do ABM without having a million-dollar tool stack, because ABM is not about the tool stack but your strategy and how you execute it.
We’re not going to provide you with flashy decks without execution. Our team of A-player operators is going to plug into your Slack, stay synced, and act like a part of your team.
We focus on message-market fit. Our team will identify your segments, run cold outbound tests, send emails with different messages, and see which ones resonate with your ICP.
Specialization: Signal-based outbound. Restartt plans, builds, and optimizes for your ABM infrastructure, including setting up your website, external, and engagement signal infrastructure, as well as building and maintaining Clay webhooks to be used as signal databases.

RevvGrowth: The agency combines hyper-personalized 1:1 programs (LinkedIn, direct email, and custom landing pages) with AI-assisted human workflows to reach out to priority accounts.

One-to-few ABM (ABM lite) involves targeting mini clusters of accounts (e.g., 10-15) with shared challenges (e.g., their current solution is too expensive) using industry- or role-specific personalization across outreach, ads, and even events.
Some of the best SaaS ABM agencies for this type of ABM are the following:

How can you choose the best SaaS ABM agency for your needs?
When choosing a SaaS ABM agency, consider the following:
Specialization: If I were you, I’d look for agencies that specialize in SaaS and the ABM model you need (1:1, 1:few, 1:many). An agency that runs ABM programs for SaaS buying journeys will better understand your product-led funnels, typical sales cycles, and buying committees.
Approach to ABM: Ask the agency to see how they approach ABM for a SaaS company in terms of how they select accounts, how they validate messaging, and how they use your ICP insights into their account-based campaigns.
Results: Take into consideration the results and case studies not only of the agency itself, but of the operators of your account.
Reviews: Check verified, in-depth client reviews and long-form testimonials on review platforms like Clutch to see how the ABM agencies perform across strategy, execution, and account handoffs.
Pricing: Compare minimum retainers, typical project sizes, and whether the ABM agency charges for media, tech stack licenses, or only for work done.
Contract length & terms: You should check the proposed contract length and see if there’s an option for monthly rolling contracts.
ABM tech stack: Check whether they use an internal or already purchased tech stack, or require you to buy new platforms to start working. Having to buy ABM tools can seriously add up to your final costs.
(Bonus) Cultural fit and comms: You want an agency that can plug-in to your communication tools and work alongside your team, as if you hired someone. You wouldn’t want to chase the team over email or wait until the weekly catch-up to ask them a question.
How can you view reviews for SaaS ABM agencies?
To view reviews for SaaS ABM agencies, you should start with their verified B2B reviews, such as Clutch, G2, and even Google Reviews.
These should give you a benchmark of what kind of pricing and level of service you can expect.
After that, I’d proceed with their website and read their case studies to get an idea of their overall approach to ABM and the results they’ve seen for other clients.
Lastly, this is something that I like to do when selecting vendors of any kind, I like to check out the companies they say they’ve worked with before and contact them on LinkedIn.
I want to see if they’ve lied about the companies they’ve worked with, and see if the case studies match what really happened with the account.
How much does it cost to hire a SaaS ABM agency?
Hiring a SaaS ABM agency can cost between $1,000/month and up to $200,000+/year, depending on scope.
The factors affecting the cost of hiring a SaaS ABM agency are:
The level of service you need, including strategy, execution, content production, paid media management, etc.
Tech setup and tool stack, including whether you want an agency with a million-dollar tech stack or one running on freemiums.
Desired media spend and platforms, as many agencies charge a % of your media spend and also add platform fees (i.e., advertising on multiple platforms will increase your costs).
Expertise of the operators, including whether you want an agency that outsources strategy and execution, or an agency where you will work with seasoned GTM engineers.
Program type, where 1:1 ABM is typically more expensive than 1:many because of tool and labor costs.
SaaS ABM agencies have different pricing plans based on either a monthly retainer, where all costs are condensed into a single plan, a project fee, where the whole project’s costs are calculated up-front, or hourly, where the agency will bill you based on how much time they spent on your account to grow it.
There are also agencies that charge based on outcome (e.g., meetings booked).
To consider the pricing of SaaS ABM services, take into account:
The service lines you want to go for, which you should be able to figure out when you’re having a discovery call with the agency.
The total cost of ownership, including the agency’s fees, your media spend, and ABM tech licenses (if you have to buy them).
What’s included vs. add-ons, including additional charges for media spend over a certain threshold, dev costs, or content costs if that labor is outsourced.
How can you collaborate with a SaaS ABM agency?
Agency collaboration refers to the working model, communication cadence, and shared ownership of campaign execution, reporting, and optimization between your internal teams (e.g., marketing, sales, and customer success) and the SaaS ABM agency.
To better collaborate with the SaaS ABM agency you’ll hire, consider asking them:
Who will actually be leading the account? You might get pitched by the founder or a senior-level partner, but then be assigned to a junior account manager with outsourced labor.
What are the communication channels and ways of keeping track of tasks, including weekly syncs, Slack, and project management tools?
How will they align with your current sales process, including lead routing, SLA, and playbooks?
What data access and integrations will they need, including access to your CRM, analytics, and ad accounts?
How will success be defined and reported, including clear KPIs, attribution and dashboards?
SaaS ABM agencies can collaborate with clients in different ways, including:
A completely managed model, where the agency runs both strategy and execution end-to-end.
A hybrid model, where the agency owns the strategy and high-skill pieces, while your team handles execution for parts of the program.
An advisory, consulting agreement, where the agency provides playbooks and training while your team does the work.
A plug-in team (best results), where an agency embeds operators into your Slack and works like an extension of your team.
Hit the restart button on your ABM campaigns
Restartt offers the most efficient GTM team you’ll never build.
Our team of A-player operators designs and runs account-based programs of signal-based outbound with no handoffs to juniors.
If you don’t want to:
Find the right talent, as in-house GTM hires are expensive and slow to ramp.
Work with other old-school agencies and freelancers who will spam high-intent leads with generic, unvalidated messages.
Drown in GTM bloat, ever-thinking about whether you should do podcasts, events, founder-led content, or LinkedIn Ads.
Then you can partner with an SaaS ABM agency run by people who have built SaaS companies from zero to exit and have actually done this before for 100+ start-ups.
