How do the 8 outbound agencies compare by market, channel and price?
These eight agencies all run outbound for B2B software companies: they research the market, build the prospect list, write and send the outreach, and hand qualified conversations or booked meetings to your sales team. They differ most in the regions they cover, the channels they use and how they bill.

What does a B2B outbound agency do for a SaaS company?
A B2B outbound agency runs the top of your sales funnel for you: it defines the ideal customer profile, sources verified contacts, writes cold email and LinkedIn sequences, sends them from warmed domains and books qualified sales meetings with decision makers. Your account executives take over at the meeting and run the deal from there.
Agencies sell this work under several names. A cold email or LinkedIn outreach agency usually runs one channel, while outsourced SDR services put dedicated sales development reps on your account who work like an extension of your team. For a new market, the agency also adapts the ICP, the message and often the language to that region.
⚠️ Important
Ask who owns the sending domains, the prospect list and the reply history before you sign. If the agency sends from its own domains, the warm-up and sender reputation stay with the agency when the contract ends.
Which B2B outbound agencies cover the US, Europe, LATAM and Asia-Pacific?
CIENCE runs outbound in the US, Europe and APAC, Hire Overseas places dedicated SDRs from three regions, and Invental Partners runs outbound in all four, so one contract can cover a home market and the next one. CIENCE prices its SDRs by where they sit, Hire Overseas matches each rep's region to the hours you need, and Invental Partners runs one research-led program per market.
1. CIENCE: SDR teams priced by region
CIENCE books qualified sales meetings for B2B teams with SDRs who call, email and message buyers on LinkedIn, and one SDR runs all three channels so your buyer hears from one person. Its Local SDR service puts in-market reps on regional campaigns, and one published case covered outbound across APAC, Europe and the US.

CIENCE splits the bill into parts. An offshore, English-speaking SDR starts at $1,750 a month and an SDR based in the US or Europe at $3,500. On top come a flat monthly fee for the campaign team and platform, a one-time setup fee and a performance bonus once an SDR reaches 60% or more of the held-meeting target. Contracts run month to month, and you can add or remove SDRs as the program proves itself.
The per-SDR figure is only one line of that bill, so ask for the full monthly total, including the bonus at 100% of target, before you compare it with other quotes.
Best for: SaaS teams that want to choose between offshore and in-time-zone SDRs market by market.
2. Hire Overseas: dedicated offshore SDRs at a flat monthly price
Hire Overseas places full-time sales development reps from the Philippines, Latin America and South Africa who work only on your account, inside your own CRM and sending tools. Each rep can run calls, email and LinkedIn outreach, and you can choose the region by the hours you need covered: Latin America for US time zones, South Africa for UK and European mornings, and the Philippines for US hours on a night shift.

Hire Overseas is one of the few providers here with a published price. Dedicated SDRs typically cost $2,400 to $3,400 a month all-in, covering the rep, payroll, HR and compliance, with pricing from $2,000 across roles. Candidates are matched in 2 to 5 days. Contracts run month to month with a 14-day money-back guarantee, and a rep who leaves is replaced at no extra cost.
Hire Overseas does not run the campaign for you. Your team owns the ICP, sequences and daily coaching, and the dialer, data and sending domains sit in your own accounts, so the warm-up, lists and reply history stay with you if you end the contract.
Best for: SaaS teams with an outbound playbook that want dedicated SDRs in the time zone of each new market, at a fixed monthly cost.
3. Invental Partners: research-led outbound for new markets
Invental Partners is a B2B outbound agency that works as an outsourced SDR team for SaaS and IT services companies. It runs cold email and LinkedIn outreach to decision makers, or to the whole buying committee on enterprise deals, and books qualified meetings for your reps. Campaigns cover the US, Europe, LATAM and Asia-Pacific, in the local language where a market requires it.

Each engagement starts with a 5-week program of market and ICP research, customer insights from 40 to 100 real buyer conversations, a verified contact list and messaging adapted by region, and replies and booked meetings start in week 5. Besides SaaS, it works with cybersecurity, AI, developer tools, fintech and health tech companies, as well as software development and professional services firms.
Cold calling is not among its channels, and nothing goes out in week 1. There is no list price: the work is quoted per contact for your ICP, and you can start with a pilot instead of a long contract.
Best for: SaaS and IT services companies that want ICP research and outbound for a new region from one team.
Which outbound sales agencies help SaaS companies enter the US market?
Belkins, SalesHive and Leadium book meetings with US buyers and combine email with phone outreach, which matters in a market where decision makers receive heavy cold outreach. SalesHive and Leadium both run month-to-month contracts, and Belkins sells packaged monthly retainers.
4. Belkins: email, LinkedIn and calling in one appointment-setting program
Belkins has run outbound lead generation for B2B companies since 2017. Its services cover appointment setting, cold email, cold calling, LinkedIn lead generation, lead research and outsourced SDRs, with deliverability consulting and HubSpot CRM consultancy on the side.

Belkins says it sets up and launches a campaign in the first 14 days, and its SaaS case studies include a company that struggled to scale into the US market. Every retainer package includes a sales audit, a total addressable market calculation, manual lead research, copywriting, appointment scheduling and no-show recovery.
The pricing page names the packages (Growth, Growth Plus and Enterprise) but shows no dollar figures, and custom SLAs and contract terms come only with Enterprise.
Best for: SaaS companies that want one agency to run email, LinkedIn and phone outreach into the US.
5. SalesHive: US-based callers plus managed email
SalesHive pairs US-based SDRs, who call from its own power dialer, with managed cold email, list building and appointment setting. It has run outbound since 2016, and an offshore calling team is available as a lower-cost option.

Its Starter, Growth and Crush plans are custom quoted by team location, channels and daily outreach volume. The managed fee includes the team, the platform and the data, with no setup fees, and annual plans cost less per month than month-to-month ones. A month-to-month plan ends at the close of the next billing month after written notice.
SalesHive lists no LinkedIn outreach, so if your buyers answer on LinkedIn more often than by phone, that channel needs a second tool or agency.
Best for: SaaS teams entering the US that want phone-first outreach from US-based callers.
6. Leadium: month-to-month appointment setting
Leadium runs appointment-setting campaigns through email, phone, LinkedIn, SMS and gifting, and it can also act as an on-demand inbound team that qualifies marketing leads. A research team builds human-sourced contact lists, and Leadium also offers outbound consulting and deliverability setup.

All contracts are month to month, and campaign managers report through shared Slack channels. New programs start only on the 1st or the 15th of the month, and Leadium guarantees its activity deliverables but not the number of sales appointments.
Best for: SaaS teams that want a US appointment-setting program with one of the widest channel mixes here.
Which lead generation agency fits SaaS companies expanding into Europe?
Sopro is the Europe-focused pick: a UK company that generates SaaS leads across the UK, the US and Europe with GDPR-compliant data. Hire Overseas can place South Africa-based SDRs whose working day overlaps with UK and European hours, and Invental Partners covers the UK, DACH, France, Benelux and Iberia country by country, with French-first and German-first outreach where buyers expect it.
7. Sopro: managed outreach from about £3,000 a month
Sopro runs multi-channel B2B outreach, including a SaaS lead generation program. A dedicated campaign team builds the audience from Sopro's own live data, writes the messages and keeps optimizing them, and the Sopro Portal shows performance and audience activity.

Sopro also turns website visits into outreach, with intent notifications and web chat. Pricing starts at about £3,000 a month, and there is no minimum contract.
Replies, calls and web chats go straight to your sales team, so your own reps book and run the meetings. That suits a team that wants to own every conversation, and it adds work for one that expected an agency to fill the calendar.
Best for: SaaS companies with their own sales team that want a steady flow of European and UK leads.
💡 Tip
For a European launch, ask each agency which countries it writes in the local language and which it covers in English only. A single English sequence sent across the EU tends to reach only the buyers who already work in English.
Which outbound agencies run campaigns in Latin America and Asia-Pacific?
Callbox and Invental Partners cover both regions. Callbox has local teams in Asia-Pacific and runs Latin American campaigns, while Invental Partners writes Portuguese-first outreach for Brazil, Spanish-first outreach for Mexico and the Southern Cone, and per-market campaigns for Singapore, Japan, Australia and India.

8. Callbox: local teams in Asia-Pacific and Latin America
Callbox has run B2B lead generation since 2004 and works with software, SaaS, cloud, cybersecurity, fintech and AI companies. It has local teams in Singapore, Australia and New Zealand, LATAM campaigns across Colombia, Brazil and Mexico, and GDPR-compliant outreach in the EU and UK.

Campaigns combine phone, email and LinkedIn, with appointment setting, outsourced SDRs, account-based programs and event promotion as separate services. Contact lists come from several data providers and are verified before outreach.
On the phone, Callbox uses AI voice agents for high-volume transactional calls and human SDRs for consultative conversations, so ask which of your calls an AI agent would make. Its pricing page estimates $16,000 to $32,000 a quarter per campaign pod with one dedicated SDR, and the exact price comes after a consultation.
Best for: SaaS companies opening Southeast Asia, Australia or Latin America that need phone outreach next to email.
How do outbound agencies price their work?
B2B outbound agencies price their work in four ways in this list: per SDR per month, as a monthly retainer, as a custom-quoted managed program, or per contact. Only CIENCE, Hire Overseas, Sopro and Callbox publish prices, so the other four need a scoping call before you can compare them.
- Per SDR: CIENCE charges by SDR location, plus team, platform and setup fees and a meeting bonus. Hire Overseas charges one all-in monthly fee per dedicated SDR.
- Retainer packages: Belkins sells named monthly packages without public prices.
- Managed program: SalesHive quotes by team location, channels and volume, Sopro starts at about £3,000 a month, and Callbox estimates $16,000 to $32,000 a quarter per campaign pod.
- Per contact: Invental Partners scopes the work to your ICP and quotes per contact, which flexes with a launch or a single test segment.
Month-to-month terms are common: CIENCE, Hire Overseas, SalesHive and Leadium all offer them, and Sopro has no minimum contract. Belkins keeps custom contract terms for its Enterprise package.
What should you automate around an outbound agency's campaigns?
An outbound program creates three kinds of data your team needs at once: positive replies, booked meetings and the prospect lists behind them. Albato is a no-code integration platform with 1,000+ connectors that moves each of them into your CRM, a sheet or a Slack channel without a developer.
Replies and booked meetings
If your agency sends from Instantly or lemlist, Albato's Instantly connector starts a flow with "Lead marked as interested" or "Lead meeting booked", and the lemlist connector offers "Emails Replied". Each one can run HubSpot "Create or update contact" and "Create new deal", Pipedrive "Create Lead" or Salesforce "Create lead". A Slack "Send message to a public channel" step then tells the account executive about the meeting as soon as it is booked.
Meetings that the agency books on your calendar can start their own flow. Albato's Calendly connector fires on "Invitee created", which works when the prospect picks a slot from a Calendly link in the outreach.
Prospect lists from the agency
Lead lists often arrive as a Google Sheet. The Google Sheets trigger "New row created" can create each contact in HubSpot, so the CRM shows who the agency is contacting and your own reps do not email the same people. Our review of cold outreach tools covers the sending tools themselves.

Before the first campaign goes live, agree on field names with the agency (email, company, country, campaign) so each reply lands in the right CRM fields. If you want replies scored before they reach a rep, our guide to AI agents for lead qualification shows how to add that step.
Leads from your website need the same route as agency replies, and our guide to lead capture software covers where form leads usually go missing before they reach the CRM.

Invental Partners fits a team that wants email and LinkedIn outreach in Portuguese or Spanish and per-market APAC campaigns, without cold calling.
How can we outsource SDR work instead of hiring an in-house team?
Outsourcing SDR work skips the hiring, training and tooling of an in-house team, and your reps keep the meetings and the closing. CIENCE, Hire Overseas, Belkins and Callbox all provide outsourced SDRs, and CIENCE publishes per-SDR prices from $1,750 a month offshore.
Which lead generation agencies work with cybersecurity and AI companies?
Callbox lists cybersecurity and AI among its industries, and Invental Partners works with cybersecurity, AI and developer tools companies as well as SaaS.
If the agency sends from its own Instantly or lemlist workspace, agree before launch on how you get access to it, because that access decides whether replies can reach your CRM through your own Albato account.
Albato's free plan covers a first two-step flow, such as sending each interested Instantly lead to HubSpot.
