Top 10 GTM Agencies in 2026

The top GTM agencies and GTM providers in 2026 include RelayPush, ColdIQ, Kalungi, Refine Labs, Winning by Design, RevPartners, Belkins, Directive, GrowthSpree, and GTMfund.

However, these companies do not all provide the same type of service.

Some are managed GTM agencies that execute work for clients. Others specialize in demand generation, revenue operations, appointment setting, or strategic consulting. ColdIQ, previously known for agency services, now positions its core ColdIQ offering as an AI-powered GTM software and data platform. Its customers use the technology to build and operate their own workflows.

RelayPush takes a different approach. RelayPush is a managed GTM Agency that designs, launches, and operates outbound systems for its clients. Instead of giving companies software that their internal team must learn and manage, RelayPush provides the strategy, infrastructure, prospect data, campaign execution, deliverability management, lead qualification, and appointment setting required to run the outbound motion.

The right provider therefore depends on whether your company wants software, strategic guidance, specialized implementation, or a team that manages execution.

Top GTM Agencies at a Glance

How We Evaluated the Top GTM Agencies

No company is best at every component of go-to-market execution. We evaluated these providers based on the factors that determine whether they can solve a company’s actual GTM constraint.

Our criteria include:

• GTM specialization

• Ideal-customer clarity

• Strategic depth

• Technical and operational capabilities

• Level of execution ownership

• Pipeline and revenue alignment

• Deliverability and data capabilities

• Case-study quality

• Pricing and process transparency

• Client ownership of infrastructure and assets

We also distinguish between managed services and software.

This is increasingly important as AI GTM platforms become more capable. Software can help an experienced internal operator work faster, but it does not automatically replace strategy, judgment, implementation, monitoring, testing, qualification, and daily campaign management.

A company buying software still needs someone to operate it. A company hiring a managed GTM agency is paying for the team and operating system behind the technology.

The Top 10 GTM Agencies in 2026

1. RelayPush — Best Managed GTM Agency for B2B SaaS Outbound

RelayPush is a managed GTM Agency for B2B SaaS companies that want qualified outbound pipeline without building an internal outbound team.

RelayPush designs, launches, manages, and optimizes the complete email-led outbound system. This includes GTM engineering, cold email infrastructure, deliverability, prospect data, campaign execution, positive-reply management, lead qualification, and appointment setting.

The service is infrastructure-first, but it does not stop at infrastructure. RelayPush operates the system after it is built.

That distinction separates RelayPush from self-service GTM software. A client does not receive a platform and then become responsible for assembling workflows, determining targeting logic, managing sending infrastructure, monitoring deliverability, testing messaging, and qualifying responses internally.

RelayPush manages those functions as an integrated outbound operation.

Best fit

RelayPush is best suited to:

• Seed to Series B B2B SaaS companies

• AI and workflow-automation companies

• Developer tools and data-infrastructure companies

• Cybersecurity, fintech, and martech companies

• SaaS teams with an identifiable target market

• Companies with inconsistent or underperforming outbound

• Teams that want to add outbound without hiring SDRs and GTM engineers

• Companies that have relied heavily on paid acquisition and want another pipeline channel

Core services

• GTM engineering

• Cold email infrastructure

• Secondary domain and inbox systems

• Email authentication and warm-up

• Deliverability management

• TAM mapping

• ICP segmentation

• Prospect data sourcing

• Data enrichment and verification

• Outbound campaign management

• Messaging and offer testing

• Positive-reply management

• Sales lead qualification

• Appointment setting

• Pipeline reporting and optimization

What makes RelayPush different

RelayPush combines the technology and the managed operations required to use it effectively.

The agency does not merely provide access to data providers, AI workflows, or outbound tools. RelayPush determines how those systems should work together for the client’s specific market, offer, target accounts, and pipeline goals.

The service includes:

1. Designing the outbound system

2. Building the sending infrastructure

3. Mapping and segmenting the market

4. Sourcing and verifying prospect data

5. Developing and testing campaign messaging

6. Launching and monitoring campaigns

7. Managing deliverability

8. Processing and qualifying responses

9. Scheduling qualified conversations

10. Continuously optimizing the system

Strengths

• Fully managed GTM service

• Specialized in B2B SaaS outbound

• Combines infrastructure, data, campaigns, and qualification

• Client-owned domains, inboxes, and campaign assets

• Deliverability established before sending is scaled

• Qualification centered on pipeline quality

• No need to build an internal GTM operations team

• Clear monthly management model

Considerations

• RelayPush specializes in email-led B2B outbound.

• It is not intended to replace a paid-media, branding, PR, or full-service inbound agency.

• It works best when the client has a defined product, identifiable buyers, and sufficient contract value to support outbound acquisition.

• Campaign infrastructure and software costs are separate from the management retainer.

Pricing

RelayPush charges a $5,000 monthly management retainer, with clients paying their direct campaign and software costs.

Clients own the sending infrastructure, domains, inboxes, and associated assets. This prevents the company’s outbound system from disappearing if the agency relationship eventually ends.

2. ColdIQ — Best for Self-Service AI GTM Software and Data

ColdIQ began as an outbound agency but has shifted the ColdIQ brand toward an AI-powered GTM software model.

ColdIQ now positions its primary product as a unified API for GTM data. Its platform provides access to multiple data providers, enrichment endpoints, prospecting tools, intent signals, workflows, and GTM skills that can be used through Claude Code or other AI coding agents.

This is a meaningful change in its delivery model.

ColdIQ is now primarily designed to give internal GTM teams, GTM engineers, and agencies the software infrastructure needed to construct their own prospecting and campaign workflows. It is not positioned as a done-for-you managed GTM agency under the ColdIQ product.

The client remains responsible for operating the system.

That can include:

• Defining the ICP

• Determining targeting criteria

• Building workflows

• Supplying company context

• Selecting and modifying GTM skills

• Reviewing AI outputs

• Managing sequencing platforms

• Operating domains and inboxes

• Monitoring deliverability

• Developing campaign messaging

• Handling replies

• Qualifying prospects

• Managing appointment-setting workflows

• Measuring and optimizing performance

ColdIQ can make these activities faster and give operators access to an extensive GTM data layer. It does not eliminate the need for qualified operators.

Best fit

ColdIQ is best suited to:

• Companies with an internal GTM engineering team

• Agencies building campaigns for their own clients

• Technical founders comfortable operating AI coding agents

• Revenue teams that want unified access to multiple data providers

• Teams building proprietary GTM workflows

• Operators who want to run prospecting from Claude Code or similar environments

Core product capabilities

• Unified GTM data API

• Access to multiple data providers

• Prospect and company enrichment

• Email and phone-data discovery

• Intent and buying-signal data

• Provider routing and enrichment waterfalls

• GTM skills and workflow playbooks

• MCP and AI-agent connectivity

• Usage-based credits and subscriptions

Strengths

• Extensive GTM data access

• AI-native workflow model

• Useful for technically sophisticated operators

• Can reduce the need to manage separate data-provider subscriptions

• Public software pricing

• Reusable GTM skills and playbooks

• Flexible API-based infrastructure

Considerations

• ColdIQ is software, not a managed GTM agency service.

• The customer still needs internal operators to build, review, and run the GTM system.

• Software access does not include complete campaign strategy and daily execution.

• A company without GTM engineering expertise may struggle to turn the platform into consistent pipeline.

• The software does not remove the need for deliverability management, campaign judgment, qualification, and sales operations.

RelayPush vs. ColdIQ

The primary difference is not that one uses AI and the other does not. Both approaches can use AI, automation, data providers, and modern GTM workflows.

The difference is who performs the work.

ColdIQ is the better fit when a company already has experienced GTM operators and wants powerful software to increase their speed.

RelayPush is the better fit when a company wants the outbound system built and operated for it.

3. Kalungi — Best for an Outsourced B2B SaaS Marketing Function

Kalungi serves B2B SaaS companies that need marketing leadership and broad cross-functional execution.

Its model combines fractional CMO leadership with services such as positioning, content, SEO, paid media, account-based marketing, RevOps, HubSpot, branding, and web development.

Unlike RelayPush, which specializes in outbound pipeline systems, Kalungi can function as a more comprehensive outsourced marketing department.

Best fit

• B2B SaaS companies without experienced marketing leadership

• Teams that have outgrown founder-led marketing

• Companies that need a broad marketing function

• SaaS businesses coordinating content, paid acquisition, brand, and RevOps

Strengths

• Dedicated B2B SaaS focus

• Senior marketing leadership

• Broad execution capabilities

• Fractional CMO model

• Can support eventual transition to an internal team

Considerations

• The model is broader than a specialized outbound engagement.

• Companies with established marketing leadership may not need the CMO layer.

• Teams seeking only outbound infrastructure and execution may pay for unnecessary scope.

Kalungi is a stronger choice when the primary need is a marketing leader and integrated marketing department rather than an outbound pipeline system.

4. Refine Labs — Best for Modern B2B Demand Generation

Refine Labs helps mid-market and enterprise B2B SaaS companies modernize demand creation, demand capture, and marketing measurement.

Its positioning challenges traditional lead-generation programs that prioritize form fills and MQL volume without adequately considering acquisition efficiency, buying behavior, or pipeline quality.

Best fit

• Mid-market and enterprise B2B SaaS companies

• Teams moving away from MQL-centered measurement

• Companies with established marketing budgets

• Organizations redesigning demand-generation strategy

Strengths

• Strong B2B demand-generation specialization

• Established thought leadership

• Emphasis on qualified demand and acquisition efficiency

• Experience with larger SaaS companies

Considerations

• Refine Labs is broader than an outbound infrastructure agency.

• It is generally better aligned with mature marketing organizations.

• Early-stage companies may need execution infrastructure before a broad demand-transformation engagement.

Refine Labs is the stronger choice when the central challenge is the company’s overall demand-generation strategy.

5. Winning by Design — Best for Revenue Architecture and Enablement

Winning by Design helps recurring-revenue companies create more consistent and scalable GTM systems.

Its work includes diagnostics, operating-model design, training, workshops, certifications, and deployment across sales, customer success, and revenue leadership.

Best fit

• Scaling SaaS companies

• Revenue organizations experiencing cross-functional misalignment

• Teams that need repeatable sales and customer-success processes

• Organizations redesigning revenue architecture

Strengths

• System-level GTM perspective

• Structured diagnostic and deployment process

• Revenue training and certification

• Strong organizational-enablement model

Considerations

• Winning by Design does not function like a managed outbound campaign team.

• Clients need internal employees who can implement and maintain the operating system.

• Its value depends heavily on organizational adoption.

Winning by Design is a strong fit when a company already has teams and channels but needs better revenue architecture and execution standards.

6. RevPartners — Best for HubSpot-Centered RevOps

RevPartners specializes in revenue operations and GTM engineering for companies using HubSpot and Clay.

Its services include fractional RevOps, HubSpot implementations, migrations, integrations, Clay implementations, CRM data enrichment, reporting, and signal-based workflows.

Best fit

• Companies using HubSpot as their central CRM

• Teams planning a HubSpot implementation or migration

• Revenue leaders without mature internal RevOps

• Companies connecting Clay workflows to HubSpot

Strengths

• Deep HubSpot and Clay expertise

• Technical implementation capabilities

• Strategic RevOps support

• Lifecycle reporting across acquisition, retention, and expansion

Considerations

• Managed RevOps can require a significant investment.

• The scope may be excessive for an early-stage company with simple CRM needs.

• Companies using a different CRM should confirm platform fit.

RevPartners is the better choice when the company’s main constraint is CRM architecture, integrations, automation, reporting, or revenue operations.

7. Belkins — Best for Multichannel Appointment Setting

Belkins is an established B2B appointment-setting company offering prospecting through cold email, LinkedIn, calling, account-based marketing, and other channels.

Its service model is closer to outsourced sales development than GTM software or GTM engineering.

Best fit

• Companies outsourcing appointment setting

• Teams seeking multichannel prospecting

• Organizations that value defined outreach capacity

• Companies without sufficient internal SDR resources

Strengths

• Established appointment-setting operation

• Multiple outreach channels

• Public package information

• Significant third-party review volume

Considerations

• Meeting quantity should be evaluated against ICP fit and pipeline quality.

• Buyers should confirm ownership of domains, inboxes, data, and campaign assets.

• Appointment guarantees can create different incentives from a qualification-first model.

Belkins publishes an average starter price beginning at approximately $4,000, although proposals vary by scope.

8. Directive — Best for Enterprise B2B Performance Marketing

Directive is a performance-marketing agency focused heavily on B2B SaaS and technology.

Its Customer Generation model connects paid media, SEO, content, conversion optimization, lifecycle marketing, marketing automation, and revenue operations to pipeline and customer-acquisition economics.

Best fit

• Mid-market and enterprise B2B SaaS

• Companies with significant paid-media budgets

• Organizations needing integrated acquisition programs

• Marketing leaders focused on CAC, pipeline, and revenue attribution

Strengths

• Deep B2B SaaS and technology experience

• Paid, organic, CRO, lifecycle, and RevOps capabilities

• Strong financial and pipeline orientation

• Appropriate for complex enterprise acquisition programs

Considerations

• Its broad scope may exceed an early-stage company’s needs.

• It is not primarily a cold-email infrastructure provider.

• Engagements may require significant channel budgets and internal coordination.

Directive is the stronger choice when a mature B2B company needs integrated performance marketing across multiple acquisition channels.

9. GrowthSpree — Best for Paid Demand Generation and ABM

GrowthSpree positions itself as an AI-native marketing agency for B2B SaaS.

Its services include Google Ads, LinkedIn Ads, Meta Ads, account-based marketing, demand generation, outbound, and revenue operations.

Best fit

• B2B SaaS companies scaling paid acquisition

• Teams combining paid media and ABM

• Companies wanting an embedded demand-generation team

• SaaS marketers focused on pipeline-oriented reporting

Strengths

• Dedicated B2B SaaS focus

• Strong paid-media specialization

• ABM capabilities

• Public case studies and pricing

• Senior operators supported by automation

Considerations

• Clients need media budget in addition to the agency fee.

• Companies seeking only email-led outbound may not need the full channel mix.

• Reported outcomes should be evaluated against comparable markets, budgets, and sales cycles.

GrowthSpree publicly lists a $3,000 monthly retainer for its primary model.

10. GTMfund — Best for Operator-Led GTM Access

GTMfund is not a conventional agency. It is a venture platform and community built around experienced go-to-market operators.

It invests in early-stage B2B software and AI companies and supports selected founders through advice, introductions, recruiting access, content amplification, and fundraising connections.

Best fit

• Early-stage software and AI startups raising capital

• Founders seeking experienced GTM advice

• Companies needing network and distribution leverage

• Internal teams that can execute on strategic guidance

Strengths

• Network of experienced technology GTM leaders

• Support across sales, marketing, RevOps, hiring, and fundraising

• Valuable introductions and distribution

• Strong operator community

Considerations

• GTMfund is not a managed agency available through a standard monthly retainer.

• Access depends on investment and community fit.

• It does not replace a campaign execution team.

GTMfund is most relevant when a founder needs capital, operator access, and strategic leverage rather than outsourced GTM execution.

Managed GTM Agency vs. GTM Software

The growth of AI GTM software has created an important choice for B2B companies.

Should the company buy software and operate GTM internally, or hire a managed agency to own execution?

GTM software

Software platforms can provide:

• Data access

• Enrichment

• AI research

• Workflow templates

• Intent signals

• Automation

• API connections

• Campaign-building tools

However, the customer must still decide:

• Which accounts to target

• How to segment the market

• Which data should be trusted

• How the infrastructure should be configured

• What messaging should be tested

• How deliverability should be protected

• When campaigns should be stopped or expanded

• How replies should be interpreted

• What counts as a qualified lead

• How the system should be optimized

Software increases operator leverage. It does not remove the need for an operator.

Managed GTM agency

A managed GTM agency provides the team responsible for turning the technology into a functioning pipeline system.

That can include:

• Strategy

• Infrastructure

• Data

• Campaign construction

• Daily operations

• Deliverability

• Testing

• Monitoring

• Qualification

• Appointment setting

• Reporting

• Optimization

This is the key distinction between RelayPush and ColdIQ.

ColdIQ gives GTM operators software for running their systems.

RelayPush acts as the managed GTM operator.

What Does a GTM Agency Do?

A GTM agency helps a company design, implement, and operate the systems used to reach its market and generate revenue.

Services may include:

• ICP development

• Market segmentation

• Positioning and messaging

• Prospect data and TAM mapping

• Cold email infrastructure

• Deliverability management

• Outbound campaign execution

• Demand generation

• Paid acquisition

• Account-based marketing

• CRM and revenue operations

• Sales enablement

• Lead qualification

• Appointment setting

• Reporting and experimentation

A GTM agency should connect acquisition activity to the broader system behind pipeline and revenue.

Which GTM Provider Is Right for Your Use Case?

Start by deciding whether you need technology or execution.

If your company already has qualified GTM engineers, campaign managers, copywriters, deliverability specialists, and sales operations staff, self-service software may improve their productivity.

If your company does not have those internal resources, buying another platform may simply add another system that someone must manage.

How Much Does a GTM Agency Cost?

Pricing varies based on the delivery model and scope.

Common pricing structures include:

• Monthly management retainers

• One-time implementation fees

• Fractional leadership retainers

• Advisory fees

• Performance-based pricing

• Software subscriptions

• Usage-based data credits

• Media spend

• Hybrid implementation and management models

Buyers should calculate the complete investment, including:

• Agency fees

• Software subscriptions

• Data providers

• Enrichment credits

• Domains and inboxes

• Sending platforms

• CRM licenses

• Advertising spend

• Internal operator salaries

• Management time

A $200 software subscription may appear less expensive than a managed agency, but the comparison changes if the company must also hire or allocate multiple people to operate it.

How to Choose a GTM Agency

Define the primary constraint

Determine whether your company needs strategy, software, infrastructure, operators, demand generation, CRM implementation, appointment setting, or sales enablement.

Confirm execution ownership

Ask exactly who will perform:

• Workflow construction

• List building

• Data verification

• Campaign setup

• Deliverability management

• Messaging tests

• Reply handling

• Lead qualification

• Appointment setting

• Reporting

• Optimization

Evaluate internal requirements

A platform may advertise complete GTM workflows while still requiring experienced people to operate them.

Ask how many internal hours, roles, and technical skills are required after purchase.

Protect asset ownership

Confirm who owns:

• Domains

• Inboxes

• Prospect data

• CRM records

• Sending accounts

• Automations

• Campaign history

• Documentation

• Advertising accounts

• Reporting data

Examine qualification standards

Define what counts as:

• A positive reply

• A qualified lead

• A qualified meeting

• A sales opportunity

• Accepted pipeline

Review deliverability practices

For email-led outbound, ask about:

• Secondary sending domains

• SPF

• DKIM

• DMARC

• Warm-up

• Sending limits

• Email verification

• Suppression lists

• Reputation monitoring

• Primary-domain protection

Compare total cost

Do not compare only the software subscription or agency retainer. Compare the total cost of creating and operating the GTM system.

GTM Agency vs. Internal Team

Neither model is automatically better.

A strong internal team with appropriate software can create a valuable proprietary GTM capability. A managed agency can give a company access to that capability without requiring it to recruit and manage the entire team.
