Best GTM Engineering [RevOps] Agencies in 202519 min read

Companies searching for the best GTM engineering (or RevOps) agencies usually have one thing in common: they’ve hit a wall. 

And while agencies engineer those systems, a tool like ZenABM will de-anonymize your target account ad engagements, and give you account scoring + intent out of the box to ensure you’re targeting and engaging the right accounts at scale. Paired together, they provide both strategy and precise execution.

Below, I’m breaking down the best agencies you can work with, how they operate, where they shine, and where they may not be ideal for your desired revenue growth.

Comparison Table: Best GTM Engineering Agencies/ RevOps Agencies at a Glance

1. Restartt

Restartt is a GTM engineering agency that builds predictable pipelines through signal-based workflows. They focus primarily on connecting intent data with outbound execution.

Their pricing starts at $6,500/month for one service.

Here’s what they do:

Signal-Based Outbound

The consultants track high-intent website visitors using tools like Warmly, Clay, and Instantly, then automate outreach through email and LinkedIn. Pretty straightforward.

Paid Ads

Restartt runs SaaS PPC and ChatGPT Ads, integrating paid campaigns with their outbound work to maximize reach.

Founder Branding

This one’s unique: they ghostwrite for SaaS founders to build thought leadership on LinkedIn while their outbound and paid efforts drive pipeline.

What to Consider

While they offer a reliable GTM function, Restart doesn’t explicitly cover RevOps (no CRM architecture, revenue reporting, or cross-departmental alignment). If you’re scaling and need that layer, you’ll probably need to supplement with dedicated RevOps support.

In addition, their pricing starts at $6,500/month for one service.

Best For

Early-stage B2B SaaS startups that want to scale demand quickly with systems thinkers. You get modern outbound, paid ads, and founder-led content (without building in-house teams).

2. SalesCaptain

SalesCaptain specialises in GTM strategy and multi-channel execution for B2B companies. They support early-stage startups launching to market as well as growth-stage SaaS, agencies and enterprises that need a structured GTM engine.

They can create a GTM plan from scratch or help you optimize what you already have. It all depends on how far you are with your own strategy. Here’s what to expect:

1. ICP and Buyer Journey Definition

Every engagement starts with deep research into your market, audience, and positioning.

SalesCaptain helps you define your Ideal Customer Profile (ICP), map the buyer journey, and uncover what motivates action at each stage.

They use sales and intent data to align your messaging to the right personas, ensuring every touchpoint feels timely and relevant.

2. GTM Planning and Messaging

With audience clarity established, the team outlines channels, sequencing, and messaging frameworks.

This includes the actual words and creative assets you’ll use across campaigns, so your value proposition lands consistently whether it’s on LinkedIn, email, or paid ads. They focus heavily on message-to-market fit, what to say, to whom, and when.

3. Sales Infrastructure and AI-Driven Systems

Once the strategy is ready, SalesCaptain builds the infrastructure to execute it. They set up sales systems, integrate CRM data flows, and use tools like ChatGPT and Generative AI to personalize and scale outreach automatically.

4. Multi-Channel Campaign Execution

SalesCaptain runs campaigns across LinkedIn, cold email, SMS, and paid channels. Essentially, they’ll select a mix that best fits your market.

Then, they’ll push outbound and combine creative content, retargeting, and sales engagement sequences to generate qualified conversations that lead to revenue.

5. AI-Powered GTM Coaching

Beyond done-for-you execution, SalesCaptain also offers AI GTM Coaching, a program for founders and in-house teams that want to build internal capability. It teaches teams how to use modern GTM tools, automate manual tasks, and apply AI in their outbound and content workflows. The program is priced at $2,900 for training, templates and live coaching, although you may also qualify for a discount.

What To Consider

SalesCaptain’s GTM approach is intensive and best suited for teams ready to move quickly. If you’re still validating product-market fit or lack foundational marketing assets, the pace might feel high before your core offer is ready.

Also, while some pricing guidance exists for their coaching program, straightforward pricing for full agency engagements is less transparent in all cases.

That said, Clutch shows that their project size minimums start around $5,000+.

Best For

Startups with strong products but little GTM structure, and scaling SaaS/agency teams that want a unified strategy and execution engine (audience, messaging, multichannel campaigns) rather than hiring multiple specialists or building in-house from scratch.

3. Workflows.io

Workflows.io is a GTM engineering and RevOps agency built around automation-first growth.

They don’t run isolated campaigns. They build operational efficiency that connects content, outbound, and operations into one repeatable engine.

Some of their services include: 

Content Engine

They set up a flow of LinkedIn and website content that builds authority and gives sales teams assets they can actually use in conversations for customer success.

ABM Programs

Workflows.io runs full account-based marketing programs where they identify and prioritize high-value accounts based on fit and intent signals. 

Then, they coordinate multi-channel campaigns (personalized ads, targeted content, and sales plays) around those specific accounts. This isn’t just “enterprise outbound,” but proper ABM with account selection, account-level engagement tracking, and coordinated touchpoints across marketing and sales.

If you’re targeting a defined list of dream accounts that could actually drive success for your team, this is the play.

Outbound

Separate from ABM, they also run volume outbound using enriched data and workflow automation.

They execute personalized outreach at scale across email and LinkedIn, helping you fill the pipeline beyond your core target account list.

AI-Powered RevOps Automation

Their “RevOps agents” handle repetitive yet critical tasks, such as lead routing, CRM hygiene, data enrichment, and workflow triggers to engineer revenue outcomes.

So, your sales operations team runs more smoothly without adding headcount, and your data remains clean enough to actually trust your reporting.

What to consider

Workflows.io requires a minimum three-month commitment tied to measurable outcomes.

But they don’t share upfront cost information, which makes it harder for smaller teams to gauge fit before getting on a sales call.

Best For

SaaS startups and scale-ups that want an automation-first approach:

• content
• ABM
• outbound
• and RevOps workflows…all in one package.

Especially good if you’re trying to coordinate multiple GTM motions without spinning up separate agencies or hiring various departments.

4. Bluepencil

Bluepencil is a growth marketing agency based in Dubai that focuses on one thing: keeping your sales team busy with opportunities that matter. 

They do this through:

Intent-Based Outbound

Bluepencil builds hyper-targeted outbound campaigns that trigger when buyer signals arise (think website behavior, content downloads, or engagement spikes).

They combine human insight with AI to accelerate prospecting, which actually increases speed and quality during the buying process versus typical SDR-led efforts.

LinkedIn Personal Branding

This one’s deeply embedded in everything they do. Bluepencil offers leadership and founder branding with content workflows that help execs stay visible, engage their community, and generate content ideas via AI.

The goal? To ensure your messaging aligns across outbound and paid touchpoints. They treat branding as part of the pipeline engine.

Integrated Paid Media

Bluepencil uses ads to amplify content reach, generate top-of-funnel leads, and retarget engaged accounts.

Their paid media isn’t standalone, but rather built to reinforce outreach and branding, ensuring prospects see consistent messaging across channels.

Bluepencil is also transparent about outcomes.

One case example: they generated $773,000+ in pipeline in three months using their outbound + media + content stack.

Bluepencil pricing

While Bluepencil publishes pricing and pipeline claims, the details aren’t fully quantified.

You’ll likely need discovery calls to learn whether creative, messaging revisions, or platform costs are included or charged extra.

Best For

Mid-market B2B and SaaS companies, especially in the GCC and MENA region, that want a tightly orchestrated demand engine that combines sales and marketing.

If your priority is visible leadership, cohesive messaging across touchpoints, and scaling the pipeline reliably (not just volume cold outreach), Bluepencil is a strong option.

5. ColdIQ

ColdIQ is an outbound-first GTM agency that builds modern prospecting systems with automation, AI, and deliverability expertise.

They provide the technology to replace slow, manual prospecting with a repeatable engine that produces qualified meetings at scale. 

They focus on email and LinkedIn outreach as follows:

Multi-Channel Outbound: Email + LinkedIn

The sales marketing agents draft sequences for both channels using AI and enrichment tools (Clay, FullEnrich, etc.) to personalize messages at scale.

So you’re hitting prospects where they’re active, inbox and LinkedIn feed.

If you’re running LinkedIn ads for ABM, ColdIQ’s LinkedIn outreach layer can extend your reach beyond paid campaigns, turning ad engagement into direct conversations.

Deliverability as Infrastructure

ColdIQ treats deliverability like infrastructure, so they set up and optimize secondary sending domains and mailboxes, configure technical records (SPF, DKIM, DMARC), and run warm-up processes before sending any outreach.

First sends usually happen in week three after contract. That ramp time protects your sender reputation and ensures long-term inbox placement, which is critical if you’re planning to scale email outbound seriously.

They even offer a separate “ColdIQ Inboxes” product (pre-warmed Gmail and Outlook inboxes) specifically for cold outreach.

AI-Powered Personalization at Scale

ColdIQ uses AI for message tailoring across both email and LinkedIn.

They research contacts, verify emails, and auto-sync insights so outreach feels contextually informed (not like a blast).

You’ll end up with fewer bad addresses, more relevant first touches, and higher reply and conversion rates.

Intent-Driven Targeting

Then, it connects to yoour existing processes and what you’re probably already doing with LinkedIn ads.

ColdIQ monitors buying signals like hiring surges, ad spend increases, office openings, and acquisitions to trigger timely outreach.

They use tools like Clay, Unify, and Common Room to track intent signals and enrich contact data.

If you’re tracking which accounts engage with your LinkedIn ads, ColdIQ can add outbound to that: reaching the same accounts that clicked your ads with personalized email and LinkedIn messages.

So, you’ll close the loop better: your ads surface intent, ColdIQ acts on it.

CRM Integration & Lead Tracking

ColdIQ provides CRM like Hubspot and Salesforce) implementation, and gives client logins to their sending tool, where you can see metrics like:

• Number of leads contacted
• Emails sent
• Open rates
• Positive reply rates
• Email-to-lead ratio and contact-to-lead ratio

Everything syncs into your CRM, so campaign performance flows directly into your sales systems.

 

Working with ColdIQ – things to consider

ColdIQ’s model requires setup time and ongoing operational oversight: mailbox warm-up, domain management, and continuous deliverability monitoring.

Expect a 2–3 week ramp before first sends, plus regular tuning of deliverability and sequences. If you need instant, one-off volume, this isn’t the play.

Best For

Scaleups and growth-stage B2B SaaS that treat outbound as a primary channel and need multi-channel (email + LinkedIn) prospecting systems with SDR augmentation, deliverability expertise, and CRM integration to sustain pipeline at scale.

6. Lead Pack

Lead Pack is a lead generation and sales development agency focused on helping B2B startups and professional services firms build steady outbound pipelines.

Their core offering is the Outbound Starter, a 3-month package designed to deliver regular sales calls via cold email campaigns. 

This is what they do:

Personalized Cold Email Campaigns

Lead Pack emphasizes personalization in their outbound email campaigns.

They tailor content to the specific situation at the target company or the individual contact, such as recent hires, role changes, or other contextual signals.

They also test multiple personalization angles in each campaign and pick the ones that will have the biggest impact on results.

LinkedIn Outreach

Beyond email, Lead Pack also runs LinkedIn outreach as part of their campaigns.

This provides multi-channel coverage, reaching prospects in both their inbox and their LinkedIn feed.

You can run LinkedIn ads to surface intent with Lead Pack’s outreach to turn ad engagement into conversations.

Technical Setup & Infrastructure

Lead Pack handles the technical setup, including two outbound domains, five mailboxes with a good sending reputation, dedicated Calendly, and CRM migration.

They don’t use your primary domain for outreach, protecting your main domain reputation while scaling sending volume safely.

Their Outbound Starter package also includes three segments with separate email cadences, allowing them to test different messaging angles and target specific profiles. They iterate campaigns through A/B testing and optimization throughout the engagement.

CRM & Tech Stack Integration

Lead Pack is platform-agnostic and has experience with HubSpot, Salesforce, Pipedrive, Close.com, Growbots, Apollo, Outreach.io, and more.

So handoff and tracking work smoothly, regardless of your stack.

LeadPack’s pricing & limitations

While Lead Pack’s simplicity and clarity are strengths, the trade-off is in strategic scope. 

Their offering centers primarily around outbound/email outreach, as well as appointment setting; they do not appear to offer deep GTM strategy, advanced content engines, or RevOps infrastructure that could drive revenue.

Additionally, their exact pricing isn’t published on the site, so you’ll need to schedule discovery calls to understand the total costs.

Best For

B2B startups and professional services firms that need to build a steady outbound pipeline from scratch and want an agency to handle the technical setup, personalization, and campaign iteration.

Especially good if you’re starting from zero and need someone to set up your entire outbound infrastructure and deliver regular sales calls without building an in-house SDR team.

7. RevPack

RevPack is a RevOps consultancy and GTM engineering agency focused on B2B SaaS, digital agencies, and tech companies.

They help companies build a predictable revenue machine internally and have generated over $ 84 M in revenue for clients, deploying 800+ automation workflows. 

Here’s how they do it:

GTM Audit & Workflow Automation

RevPack offers over 20 out-of-the-box workflows and automations from its proven library.

They can get a proof-of-concept automation or workflow live in just 14 days and also offer a 90-day engagement drive focused on pipeline generation, audits, automations, new tech stack setups, or revenue-driving AI agents.

Fractional RevOps

Their Fractional RevOps service provides 40 hours per month with a 3-month minimum commitment, including Slack communication, weekly calls, and access to top RevOps and sales experts.

They either jump straight into projects on your roadmap or start with a GTM audit to identify gaps.

ABM  Workflows

RevPack works with ABM, or at least account-level flows. Their service mix includes outbound prospecting workflows that utilize account segmentation and prioritized outreach. 

The use of workflow automation/automation plus account targeting means they span both demand generation and RevOps.

Performance

Most clients see initial improvements within 14 days, with significant results typically achieved within 90 days.

Their approach focuses on achieving quick wins first, followed by systematic optimization.

Client testimonials highlight reaching over 100 high-value prospects monthly through automation and achieving strong traction quickly.

Drawback

RevPack leans heavily toward automation and infrastructure over creative branding or high-touch content strategy.

You’d likely need supplementary project consulting agencies or dedicated customer success teams for creative or messaging polish.

Also, while they build ABM workflows, they don’t provide thorough LinkedIn ad-level engagement tracking. So you’d need to layer that data separately if you want to know exactly which accounts clicked which ads.

Best For

Any B2B SaaS Chief Revenue Officer or tech companies that have some outbound or demand generation already underway but are hampered by leaky tools, disconnected workflows, or unreliable data.

If you want a reliable RevOps partner (clean CRMs, automation that scales, better ABM alignment), RevPack will deliver value early and often.

Pricing

RevPack publishes transparent pricing for its three main service tiers. The Quick Win package starts at $1,750 per automation, the Strategic RevOps Project at $4,500+, and the Fractional RevOps plan at $2,650+ per month.

These published prices make RevPack one of the few RevOps agencies offering clear, structured cost visibility upfront, though final quotes still vary depending on scope and complexity.

8. GrowthToday

GrowthToday is a GTM automation agency for ambitious B2B teams. They want you to stop burning time on manual outreach and broken data, and instead build sales cycle systems that scale.

So, they design, build, and automate your outbound, inbound, and RevOps workflows using Clay and AI.

Outbound Automation + Prospecting Flows

GrowthToday builds workflows that run 24/7. They research leads, personalize messages, and send them at scale with real-time triggers.

They scale the campaigns you could only run manually before, so you’ll have a better shot at your revenue goals.

From fully automated prospecting flows to AI agents and sales-triggered sequences, their systems eliminate the manual bottleneck, ensuring strategic alignment so campaigns don’t stall when someone’s overloaded.

They also support your sales enablement teams by automating the creative campaigns they’ve been doing manually, or wish they could. 

Data Integrity & Enrichment

GrowthToday cleans your CRM, automates research with AI and custom scrapers, enriches data using 100+ providers, scores leads and accounts, and monitors intent signals.

This isn’t a one-time cleanup. They keep it all clean with automated enrichment workflows.

Inbound Lead Activation & Routing

If your marketing generates leads from webinars, ads, email campaigns, and events, GrowthToday builds the team structure that scores those inbound leads, routes them automatically, follows up, and ensures no lead stalls.

What to Consider

Because GrowthToday focuses heavily on automation, data workflows, and system engineering, creative content or branding tends to be less emphasized.

If your primary need is high-touch design, storytelling, unique customer experience, or executed branded campaigns, you may need additional creative support.

While GrowthToday doesn’t clarify pricing on its website, Clutch lists their minimum project size at around $5,000, though this figure should be treated as indicative rather than definitive.

Pricing likely varies depending on your GTM scope, data requirements, and campaign complexity.

Best For

B2B SaaS or tech companies that already have some pipeline motion (either inbound or outbound) and want to scale reliably by automating outreach, cleaning dirty CRMs, scoring leads, and ensuring no opportunity slips through the cracks.

Especially good if your bottleneck is ops or outreach quantity + quality, not creative narrative.

9. Understory

Understory is a B2B SaaS growth agency that positions itself as an “allbound partner,” blending paid media, outbound, and graphic design to drive pipeline.

Here’s what they typically do.

Multi-Channel Paid Media

Understory’s paid media services include setting up ad accounts (LinkedIn, Google, Meta, Reddit, Quora, Capterra), crafting audience segments, installing pixel tracking for conversion monitoring, creative development, and dashboards that centralize ad + CRM performance.

They don’t just set up campaigns and walk away.

They monitor performance success metrics and adjust bids, targeting, and ad creatives based on early insights. As such, they proactively eliminate bottom performers, invest more in top performers, and devise new headlines, subheadlines, and CTAs to support GTM efforts.

They also create custom dashboards, joining your CRM, email, and ad platform data to provide real-time reporting on multi-channel ROI.

Hyper-Personalized Outbound

Understory operates as a full-service GTM growth partner building complex, segmented, trigger-based outbound campaigns and blending them with paid campaigns across multiple channels. 

They don’t rely solely on cold email; instead, they combine it with LinkedIn messaging. They also create bespoke sales triggers, build automations based on your website traffic, and synchronize paid media/paid search with outbound efforts.

Plus, their copywriting is tailored, they build bespoke lead lists, and use Clay for list enrichment, personalization, and ICP filtering.

Graphic Design & Creative Support

Understory offers ad creatives, landing page or campaign graphics, and iterative creative variants tied to campaign performance. 

Their process includes creative direction workshops and design workshops to leverage your company’s unique brand elements to drive growth.

What to Consider

If your growth barriers revolve around internal process breakdowns, lead scoring systems, or complex attribution setups, you may need to pair Understory with a RevOps-specialist agency.

Understory’s GTM Engineering plan starts at $12,000 per month, covering outbound infrastructure (from domain management and ICP targeting to AI-driven personalization, copywriting, and full campaign automation).

Best For

B2B SaaS companies that need high-impact demand generation, companies with existing products, some market traction, and a need for creative, multi-channel campaigns that stretch budgets wisely.

If you want to boost your pipeline via paid, outbound, and design efforts, especially when messaging and creative matter, Understory is a strong option.

Conclusion

Choosing the right GTM engineering/RevOps agency typically comes down to matching your stage and pipeline needs.

Your best option may be to combine signal-driven outbound, multi-channel paid campaigns, creative content, and automation, with enough flexibility to integrate into your existing stack. 

But if you’re running LinkedIn ads as part of your GTM motion, there’s a layer most agencies don’t provide: knowing exactly which accounts are engaging with your ads and what they’re interested in.

Without that visibility, even the best agency is left to guess at timing and personalization or make data-driven decisions.

ZenABM tracks which organization clicks your LinkedIn ads, what campaigns they engage with, and pushes that intent data directly into your CRM (so your agency’s outreach is perfectly timed, not generic).

Even as you look for your best agency from the software companies above, you can book a demo with us to see how ZenABM gives you the account-level intent data that makes their campaigns more effective.
