Key Takeaways
- Frontal is best for post-PMF B2B tech companies that want senior GTM operators embedded in their team to own execution across agreed services, including RevOps, outbound, ads, and content.
- Belkins is best for teams that want done-for-you appointment setting handled end-to-end across email, LinkedIn, and calling.
- CIENCE is best for teams that want research-heavy, multichannel outbound run at scale.
- SalesHive is best for US teams where phone-first outbound is a proven channel, run by a dedicated SDR team.
- RevPartners is best for HubSpot-native teams that want their RevOps and signal-based outbound built on HubSpot and Clay.
A sales automation agency helps B2B teams automate everything from CRM enrichment and buying signals to outbound sequences, so reps can focus on selling instead of managing tools.
But agencies differ in what they deliver. Some handle outbound for you, others automate the workflows behind it, while a few build the entire system inside your existing stack.
This guide breaks down the 5 best sales automation agencies for B2B SaaS in 2026, including key services, where each one shines, where it falls short, and who it’s best for.
A quick note on how we made this list: every agency here earns its place on the sales automation work it delivers, the stage and stack it serves, and the client results it publishes. Frontal is included in this comparison and held to the same criteria as every other provider. The right fit depends on whether you want outbound run for you, the underlying systems automated, or the full system built into your own stack.

1. Frontal: Best for B2B Teams That Want Sales Automation Built Into Their Stack
Frontal is a go-to-market partner for B2B tech companies past product-market fit with an established sales motion. We work as an extension of your go-to-market team, owning the agreed work across GTM Services, Ads, Content Engineering, and RevOps.
For sales automation, our operators build in your CRM and the tools you already use, and can stay on to run and improve it. Our team brings experience working with 250+ B2B companies.
Frontal Key Services
Sales automation is one part of our broader GTM offering. Here’s how we help teams automate their sales workflows, from CRM data and buying signals to outreach and routing.
1. Data and CRM Automation
Automation built on messy data just gets to the wrong people faster, so we start with the foundation. We audit your CRM and clear out whatever isn’t earning its place.
For example, on a recent HubSpot cleanup, we reviewed every custom object and field and removed the redundant ones, a job that would have taken months by hand and took us about a week with the right tooling.
From there, we get the data itself into shape:
- Dedupe and normalize, so one account isn’t logged several times, and the same field means the same thing everywhere.
- Waterfall enrichment, so a missing title or headcount pulls from the next source when the first is empty.
- Auto-enrichment, so new records arrive complete instead of your team backfilling every form and imported list by hand.
We work in HubSpot and Salesforce, use Clay for enrichment and workflow support, and document the data model, so your team can see how it's built. For sources to pull from, see our guide to building a B2B outbound list.
2. Buying-Signal Scoring and Account Selection
At Frontal, we believe clean data only pays off when the right account reaches the right rep at the right moment. So we capture live buying signals from the tools you already run, funding rounds, hiring and job changes, website visits, LinkedIn engagement, and tech-stack moves, then score every account on two things: how well it fits your market and what it’s doing right now.
A person on our team then approves the accounts worth pursuing and sets the weak matches aside, so a rep never chases a bad fit.
3. Multichannel Sequencing and Routing
Once an account clears approval, one signal sets the whole sequence in motion. Let’s say a target account raises a Series A. An email and LinkedIn cadence starts, a call queue builds, the account syncs into your ad audiences, and the owner gets a CRM task and a Slack alert, with the raise flagged as the reason.
Everything runs inside your own stack and the outreach tools you already use, so the rep opens the account already knowing the signal that surfaced it and why now is the moment.
4. Yours to Own, or We Run It
We can build the full system, document it inside your own tools, and hand it over for your team to run without us. Or our operators keep running the outbound, ads, and content on top of it. Either way, what we build stays yours.
Frontal Pricing
Frontal doesn’t publish set pricing because the scope depends on your stack, the state of your data, and how much you want us to run for you versus keep in-house. Book a 30-minute call, and we’ll walk you through exactly what we’d build and run for you.
Where Frontal Shines
- Senior operators embedded in your team: Our operators work as an extension of your GTM team and take ownership of the sales automation work we agree to deliver, from CRM workflows and buying signals to outreach execution. We also review accounts before we contact them, so human oversight stays part of the process.
- Built inside your own stack, and you keep it: We build and document the system inside your HubSpot or Salesforce, using tools like Clay for enrichment and supporting workflows. When the engagement changes or ends, you keep the system.
- Connected across channels from a single account list: When outbound, ads, and content are in scope, they all run off the same accounts and signals, so your reps, your ad audiences, and your content aren’t chasing three different versions of who matters.
Where Frontal Falls Short
- Best once you have a sales process in motion: Frontal is strongest when you already have customers and a working sales motion. Pre-PMF teams still working out who buys and why need a different kind of help before our work pays off.
- Not a high-volume sending shop or a cold-calling floor: If you want raw send volume or a team of dialers, that isn’t us. We build targeted, signal-driven outreach across email and LinkedIn and the data layer beneath it. If calling is your proven channel, we build the tiered list that makes those calls land, but we won’t dial for you.
Frontal Client Results

2. Belkins: Best for Teams That Want Done-for-You Appointment Setting
Belkins is a B2B lead-generation and appointment-setting agency that has run outbound for clients since 2017.
Key Services
- Appointment setting: This is their core offering. Belkins researches your ICP, runs multi-touch outreach, books qualified meetings, and handles no-show recovery, managed end-to-end by its team.
- Cold email outreach: Deliverability-first email campaigns with domain warm-up, copywriting, A/B testing, and a dedicated specialist protecting your sender reputation.
- Cold calling and LinkedIn: Manual and intent-based calling, plus LinkedIn outreach that pairs signal-based targeting and AI tiering with manual lead vetting.
- Lead research and supporting services: Manually built, AI-validated prospect lists, backed by ABM, outsourced SDR, HubSpot CRM consulting, and deliverability consulting.
Pricing
Belkins doesn’t publish standard pricing. Every engagement is scoped to a custom proposal built around your company size, total addressable market, revenue goals, and the channels you run, so you get a number after a scoping call. For a fuller breakdown of packages and pricing, see our guide to Belkins pricing.
Where Belkins Shines
- A proven, hands-off model: You hand over the target market, and Belkins runs the research, copywriting, sending, and scheduling, with a dedicated account manager reporting back. It suits teams that want meetings on the calendar without building anything themselves.
- Fast to launch with deliverability rigor: Campaigns go live in about 14 days, and a dedicated deliverability specialist warms domains and monitors sender health daily.
Where Belkins Falls Short
- A done-for-you service you don’t operate: Belkins runs the outreach with its own team and hands you booked meetings, so the capability stays with them.
- Built for teams with real budget: The white-glove, dedicated-team model is scoped for established companies, so leaner or very early-stage teams may find it heavier than they need.
- Focused on managed outbound: Belkins' core offering centers on prospecting and appointment setting. Teams looking for a broader GTM system connecting CRM workflows, outbound, ads, and content should clarify whether this falls within the proposed scope.
Customer Reviews
“I like Belkins because they are great at collaborating, communicating, and hard working. Their approach to finding cold prospects through phone calls, emails, and LinkedIn messages is effective,” shares Jordan R.
“We were offered 15 meetings over a 3 month period. However we barely got 5 overall. After the first month and a half they ran out of target customers and started sending emails to any kind of prospects that were not our target, of course they could not book any meetings that way,” says Emmanuel Massenez in his Clutch review.
Who Belkins Is Best For
- Established B2B teams that want fully managed appointment setting across email, LinkedIn, and calling, and prefer meetings delivered to them over building and owning sales automation in-house.

3. CIENCE: Best for Data-Driven Managed Outbound at Scale
CIENCE, now a graph8 company, is a managed go-to-market provider that books qualified sales meetings for B2B teams.
Key Services
- Managed SDR and campaigns: Dedicated SDR teams run outbound and inbound across email, phone, LinkedIn, ads, and SMS, with AI agents handling research, deliverability, and scheduling beside a human rep who works the conversation.
- Revenue System Setup: A forward-deployed engineer studies how your team sells, builds a model of your business, and wires it into a working system on the graph8 platform over 60 days.
- graph8 platform and data: A proprietary contact database with intent signals, visitor de-anonymization, enrichment, and a parallel-dialing voice stack that the managed service runs on.
Pricing
| Component | Pricing |
|---|---|
| GTM system setup | $5,000 one-time |
| Strategic GTM team | $2,000/month |
| graph8 platform license | $499/month |
| Optional SDR capacity | $1,500 to $6,500/month/SDR |
CIENCE also offers a 60-day Revenue System Setup starting at $9,500, with more complex builds costing up to $25,000.
Where CIENCE Shines
- Proprietary data and intent built in: The graph8 data layer gives campaigns a large contact database, intent signals, and enrichment without a separate subscription. This suits teams that want research depth behind every list.
- Multichannel execution, enterprise-proven: Email, phone, LinkedIn, ads, and SMS run together, and the model scales from startup programs to enterprise volume for clients like Okta, Microsoft, and Uber.
- Transparent, flexible commercials: CIENCE publishes its base rates, offers month-to-month terms, and lets teams adjust SDR capacity, making it easier to estimate costs before speaking with sales.
Where CIENCE Falls Short
- Centered on the graph8 platform: The system CIENCE builds and runs lives on graph8, so teams set on building natively inside their own HubSpot, Salesforce, or Clay will find it less stack-native than an in-tool build they keep.
- Costs stack in layers: Setup, a monthly team, and the platform are the base, and every SDR you add carries its own monthly rate plus a one-time onboarding fee, so a fuller program climbs quickly.
- Built for breadth and volume: The range spans high-volume programmatic outbound and telemarketing, which can be more machinery than a focused, few-hundred-accounts motion actually needs.
Customer Reviews
“There is no disconnect between Sales teams and their Growth teams. Sales was articulate in helping prescribe a solution,” shares Jeff M.
“We were extremely disappointed with the services provided by this CIENCE. Despite 6 months of interactions and repeated assurances, they did generate a single new lead for our business. Their call center reps are all located offshore and have little to no sales experiece,” says Jeremy N
.
Who CIENCE Is Best For
- B2B teams that want research-heavy, data-driven outbound run across multiple channels at scale.
4. SalesHive: Best for Phone-First Outbound
SalesHive is a US-based B2B sales development agency founded in 2016. It books qualified meetings for B2B teams and has booked more than 115,000 meetings since it started.
Key Services
- Cold calling: Trained, US-based SDRs dial your target accounts at high volume on SalesHive’s own Power Dialer, qualify interest, and book meetings straight onto your calendar.
- Email outreach: Managed campaigns where eMod AI personalizes each send, lookalike sending domains protect your reputation, and US-based responders work every reply until a meeting is booked.
- List building and data: Verified, ICP-matched lists built on the platform’s own data engine across ten BrightData datasets with ZoomInfo enrichment, so you don’t need a separate data provider.
- Dedicated team and platform: Every engagement pairs an SDR and a strategist with the SalesHive platform for intent signals, a smart inbox, AI agents, two-way CRM sync, and a live dashboard.
Pricing
SalesHive doesn’t publish pricing for its three tiers (Starter, Growth, and Crush), so you’ll need to book a call for an exact quote. Its offshore plans start at $4,500/month.
Where SalesHive Shines
- One flat fee, no lock-in: A single monthly price covers the team, platform, data, and tools, with no setup fees and month-to-month terms, which makes SalesHive easier to start and leave than most managed-outbound agencies.
- Serious phone-first execution: US-based trained callers dialing at high daily volume on a purpose-built Power Dialer make it a strong fit when the phone is a proven channel for your market.
Where SalesHive Falls Short
- You run on their platform: The Power Dialer, eMod personalization, data engine, and smart inbox are SalesHive’s own system, so the setup doesn't stay inside your stack for your team to keep and run later.
- A volume-led model: Tiers scale by daily touch count, from 100+ to 500+, so the motion is built around activity volume rather than a focused run at a few hundred signal-selected accounts.
Who SalesHive Is Best For
- US B2B teams where phone and email are proven channels and who want a dedicated, managed SDR team on a flat, month-to-month fee.
5. RevPartners: Best for HubSpot Teams That Want RevOps and Signal-Based Outbound
RevPartners is a RevOps and go-to-market engineering firm working across the HubSpot and Clay ecosystems.
Key Services
- RevOps as a service: An embedded team, which it calls a Pod, that runs inside your HubSpot on a monthly subscription, handling revenue-focused configuration, system integrations, performance reporting, and adoption against its Revenue Performance Model.
- Allbound marketing: Its Clay-powered growth line, pairing SEO, paid media, and CRM data enrichment with signal-based outbound, plus standalone Clay implementations and playbooks.
- HubSpot implementation, migration, and integration: Onboarding across Sales, Marketing, and Service Hub in 30 days or less, migrations from tools like Salesforce, Marketo, Pipedrive, Dynamics, and Zendesk, and custom integrations across the stack.
Pricing
| Plan | Pricing |
|---|---|
| HubSpot Implementation | From $1,500 |
| RevOps as a Service | $9,850 to $27,000/mo by tier, plus a $5,000 one-time onboarding fee (6-month minimum) |
| Allbound Marketing | From $12,900/mo |
| Clay Implementation | $25,000 one-time payment |
Where RevPartners Shines
- Unmatched platform credentials: It’s the only firm worldwide with Elite accreditation from both HubSpot and Clay, a HubSpot tier fewer than 1% of partners reach.
- Engineering-grade team: More coders than designers, plus 700+ HubSpot certifications, keep complex integrations and technical builds in-house.
- A real automated outbound layer: The Clay-powered allbound motion delivers signal-based outbound built for pipeline, which most pure RevOps firms don’t run alongside the systems work.
Where RevPartners Falls Short
- HubSpot as the CRM: It builds on HubSpot and migrates teams onto it, so it's a poor fit for a Salesforce-committed team that won’t switch.
- Bought as separate lines: RevOps, Allbound, and implementation are priced as distinct packages, so connecting the foundation to the outreach that runs on it means coordinating more than one engagement.
Customer Reviews
“RevPartners has been a critical partner for 3 years now. They do a fantastic job communicating progress, setting expectations, keeping projects on task and keeping us informed along the way,” says a reviewer on Clutch.
“What they implemented was extremely complex, and they left us with no explanation. Three years later, we’re still deleting things they created because it caused more mess than anything else. It feels like they overcomplicated some pretty simple processes,” shares Nicolas H.
Who RevPartners Is Best For
- HubSpot-centric B2B teams that want an embedded RevOps department building sales automation on HubSpot and Clay, rather than a done-for-you outbound service.
For the wider RevOps field, see our roundup of the best RevOps agencies for B2B SaaS.
How to Choose a Sales Automation Agency
The right agency comes down to three questions: what you’re automating, where it runs, and how it picks who to contact.
1. Decide What You're Actually Automating
“Sales automation” usually means one of three jobs, and each points to a different kind of agency:
- Outbound sent for you: Belkins and SalesHive put meetings on your calendar, but they keep the capability on their side.
- The systems under your CRM: RevPartners leads with the RevOps plumbing, and runs outreach as a separate add-on on top of it.
- The whole system, built and run: The data, the signals, and the sequences wired into one motion inside your own tools.
Pin down which one you need before you buy, so you don’t pay for scope you won’t use.
Frontal, for example, embeds operators in your GTM team to build sales automation inside your existing stack. This gives your team more execution capacity while creating documented workflows you can continue using after the engagement ends.
2. A Platform You Rent, or a System You Own
Next, decide where the automation lives, because this question alone determines who keeps it when the engagement ends. A system built into your own tools stays with you. One that runs on a vendor’s platform walks out the door with them.
CIENCE runs on graph8 and SalesHive on its Power Dialer, so the setup leaves when the contract does. Belkins keeps the whole engine on its side by design, and RevPartners builds inside HubSpot, as long as you commit to it. The question is simple: if you walk away in a year, what stays with you?
At Frontal, we build inside your HubSpot or Salesforce, connect tools like Clay for enrichment and automation, and document everything. When we’re done, you choose what happens next. Want to run it yourself? We hand over the whole thing, documented, so your team owns it. Want to keep us on it? Our operators keep running the outbound, ads, and content. Either way, the system is yours.
3. Volume or Precision in Who Gets Contacted
Another question that matters when you choose is how the agency decides who gets contacted in the first place. Automation makes it easy to reach more people, but it can backfire fast if they’re the wrong ones. Volume-led models scale by activity and measure throughput, which fits a broad, repeatable offer. A precision model reaches fewer, better-fit accounts chosen on buying signals, which fits a considered sale. Decide which your market rewards before you buy.
At Frontal, we run the precision model, score accounts on fit and timing, and keep a person approving who enters a sequence. Your reps chase only buyers worth their time, and your domain and name stay clean because automation never pushes a bad-fit account into a sequence on its own.
How Much Does a Sales Automation Agency Cost in 2026?
Pricing depends on the model. Done-for-you outbound runs on a monthly retainer or a flat fee, systems and RevOps work is billed per project or on a retainer, and a full build is scoped to your stack and the state of your data. Here’s where the five agencies in this guide charge as of October 2026.
| Agency | Pricing (as of October 2026) |
|---|---|
| Frontal | Custom, scoped on a call |
| Belkins | Custom, scoped on a call |
| CIENCE | From $2,499/mo ($2,000 team plus $499 platform), plus a $5,000 one-time setup; SDRs priced separately |
| SalesHive | Quote-only tiers; offshore plans from $4,500/mo |
| RevPartners | Implementation from $1,500; RevOps as a Service from $9,850/mo; Allbound from $12,900/mo |
The number you pay turns on a few things: how many channels you run, whether the team is run for you or built to hand over, your SDR headcount, and the shape of your existing stack. Most agencies quote after a short scoping call, so it’s worth getting two or three quotes to compare like for like.
So, Which Sales Automation Agency Is Right for You?
The right agency depends on which layer you’re automating, whether you rent the system or own it, and whether your market rewards volume or precision.
Frontal works with post-PMF B2B tech companies that need more GTM execution capacity. Our senior operators work as an extension of your team, taking ownership of agreed work across GTM Services, Ads, Content Engineering, and RevOps.
For sales automation, we build workflows inside your existing stack and can stay on to manage and improve them. If you're considering broader GTM support, see our guide to the best GTM consulting services for B2B SaaS.

FAQs
1. What is sales automation?
Sales automation uses software to handle repetitive parts of selling, like data enrichment, lead scoring, routing, follow-ups, and outreach sequences, so your team can spend time on conversations instead of manual work. In practice, it covers everything from a single automated email cadence to a full system that triggers enriched, scored, and routed outreach based on buying signals.
2. What does a sales automation agency do?
A sales automation agency builds and runs the system behind your outbound, so meetings get booked without your team stitching tools together by hand. Depending on the agency, this can mean sending outreach for you, automating data and routing in your CRM, or building the whole system, from buying signals to sequences, in your own stack.
3. What’s the difference between a sales automation agency and a lead generation agency?
A lead generation agency focuses on handing you leads or booked meetings, whereas a sales automation agency focuses on the system that produces them, the data, the buying signals, the routing, and the sequences, so the pipeline keeps coming. Some agencies do both. For a closer look at the first group, see our roundup of the best lead generation services for B2B.
4. Is automated outbound still effective in 2026?
Yes, when it’s targeted. Generic emails to large prospect lists are becoming less effective as spam filters improve and buyers ignore irrelevant outreach. A better approach is to focus on accounts that match your ideal customer profile and show relevant buying signals. Frontal uses buying signals and account-fit criteria to prioritize prospects, with human review before accounts enter outreach sequences. This helps teams maintain oversight of targeting while automating execution.
5. When should a B2B company hire a sales automation agency?
When you have an established sales process but lack the internal capacity to scale it. Common triggers include a newly appointed revenue leader who needs more execution support, outbound workflows that require too much manual work, or CRM data that isn’t being used effectively. For post-PMF B2B teams, Frontal provides senior GTM operators who extend your team and own agreed execution, from CRM automation and buying signals to outbound workflows.
