A B2B appointment setting company contacts prospects on your behalf and books qualified sales meetings onto your reps' calendars. Most do the work by phone, email and LinkedIn, and many add list building, inbox management and reporting.
Appointment setting services come in several business models. Some firms staff a dedicated team of outsourced SDRs. Others run campaigns from a shared pool of callers and charge per meeting. A third group, which includes QC Growth, embeds operators and engineers who set up the outbound system and run it with you.
The definition of a meeting differs from one vendor to the next. CIENCE reports held meetings rather than dials. Belkins counts sales-qualified meetings with decision-makers. Always ask which one your contract pays for.
Early-stage founders hit a ceiling. The first customers come from the founder's network and personal pitches, and that source dries up around the time the product has real traction. Outbound has to replace it, and outbound needs domains, deliverability, data, sequencing and someone who calls prospects every day.
Building that in-house is expensive. By QC Growth's own math, a senior in-house GTM team costs $57k to $81k per month plus 1.25% to 2.75% in equity. A mis-hire at the first sales leader slot can cost a quarter of runway before anyone notices.
Outsourcing appointment setting shortens that gap. Vendors publish their own comparisons, with Belkins saying its services cost a fourth of the in-house equivalent and Leadium claiming a 67% reduction in weighted cost. Both figures are self-reported, so verify them against your own pipeline math before you sign.
The outcome to aim for is a calendar of meetings with the right buyers, plus a system you can inspect. Meetings alone do not fix a stalled pipeline if the messaging, targeting and data behind them disappear when the contract ends.
The right type of provider depends on your stage, your buyer and how much of the motion you want to own. These are the five profiles we see most often.
You closed the first deals yourself and have a product with clear signal. You cannot afford a senior sales team and do not want to spend half your week on cold outreach. An embedded pod such as full-service GTM from QC Growth fits this profile, because it builds the outbound system and runs it with you.
Developers ignore generic outreach. These teams need messaging that respects the audience and targeting based on real signals, such as hiring, tech stack and repository activity. The dev tools GTM approach pairs operators who sold to developers with signal-based account selection.
Every buyer hears from a dozen AI vendors a week. Enterprise cycles also run longer than most seed teams expect. Appointment setting here has to produce meetings with buyers who have budget and a trigger. See how enterprise AI GTM is handled for this profile.
Provider and payer buyers respond to credibility and referrals more than to volume. A generic call center can burn the relationships you need. HealthTech GTM work needs operators with healthcare sales experience.
Companies past Series A with a documented sales script and a clear ICP can put a volume agency to work quickly. Phone-heavy firms like SalesRoads and memoryBlue suit this profile, since the pitch is already tested.
We reviewed each company's own site for services, channels, pricing and contract terms. Claims below are the companies' own unless stated otherwise. We rank QC Growth first because it is our company, and we say plainly where it is the wrong choice.
QC Growth is an embedded go-to-market team for Seed to Series A B2B software companies. It places a fractional pod inside the client's environment: a top-tier GTM operator, a GTM lead, a GTM engineer and BDR support. The pod handles strategy, outbound infrastructure, messaging, campaigns and reporting.
It does not sell meetings by the count. It builds an "Allbound" system, where inbound, outbound and partner channels share signals, and it runs the system with the founder. Its core verticals are developer tools, AI, healthtech and deep tech.
The pod works inside your tools and runs the motion day to day. When the engagement ends, the infrastructure, data and playbooks belong to you. Outbound targeting uses signal stacking, which combines firmographics, LinkedIn activity, job changes, hiring, tech stack and web visits, so outreach goes to accounts with a reason to talk.
The operators have sold in the buyer's own vertical, with experience at Gatsby, Netlify, Workpop, Uber, OctoAI and SmartBear. Clients include Grafbase, whose CEO Fredrik Björk said QC helped it land its first enterprise customers, and Eraser.io, whose CEO Shin Kim said QC built a repeatable outbound process. Burn Media Co. grew revenue from $142k in April to $181k in August, a 27.5% increase.
Packages run $7.5k to $25k per month depending on scope, on 6 to 12 month engagements. That compares with the $57k to $81k per month plus equity that QC estimates for an in-house team.
QC Growth is the strongest fit when the real problem is a missing outbound system, not a shortage of calls. It suits founders who want the motion built and who plan to own it afterward. Teams that only want a fixed number of booked calls each month should compare the volume agencies below.
Belkins is a B2B lead generation and appointment setting agency founded in 2017 and based in Dover, Delaware. It offers outsourced SDRs, cold email, cold and intent calling, LinkedIn outreach, SMS, paid ads, deliverability consulting and HubSpot CRM consulting.
It says it works with 1,000+ clients across 50+ industries and has helped them generate $2B+ in revenue.
Belkins is one of the strongest choices for breadth. Its page describes campaign setup in the first 14 days and first appointments in the following 30 days. It states that its omnichannel approach guarantees 100 to 400 appointments per year, and it notes that results depend on multiple factors.
Self-reported case studies include 145 appointments in 9 months for Cengage Learning and 116 appointments in 4 months for OpenTeleHealth. It lists a 4.9 rating on Clutch from 230 reviews.
Quote only. The company says its services cost a fourth of the in-house equivalent, which is a self-reported figure.
Belkins suits companies that want a large, multi-channel vendor to run outbound for them. It is a weaker fit for founders who want to learn and own the system, since the work stays inside the agency.
CIENCE books qualified sales meetings for B2B teams, with SDRs who qualify buyers before meetings reach the client's calendar. Services include outbound SDR teams, inbound follow-up, cold calling, cold email and B2B contact data. It also sells broader go-to-market work such as playbooks and revenue system setup.
It says it has served 2,500+ clients over 10+ years and published 115+ case studies.
CIENCE is one of the smartest choices for flexibility. Its pricing is a fixed monthly fee for the team plus a commission per held meeting, on a month-to-month basis, and clients can add or remove SDRs as needed. It reports held meetings rather than dials.
It claims 5 to 20+ qualified meetings per month per SDR depending on industry and target, with campaigns live in under 14 days. Case studies include 227 appointments in 4 months for SendBird and 110 qualified meetings in 6 months for Mandolin.
Fixed monthly fee plus a commission per held meeting. The amounts are shared on request.
CIENCE is a sound pick for companies that want pay-for-performance terms and the option to scale a team up or down. Founders who need strategy and engineering alongside meetings may find the scope narrow.
SalesRoads is a sales outsourcing firm that builds dedicated outbound teams for B2B companies. It offers appointment setting, lead generation and outsourced SDR programs, and it lists inbound appointment setting, account reactivation and list building.
Its work centers on calling and email, with research drawn from 14+ data sources. Focus industries are manufacturing, federal and state government, healthcare and SaaS.
SalesRoads is one of the stronger options for phone-first programs. Each program launches in 15 business days with a dedicated SDR team, a client strategist, a performance coach, an optimization specialist and a research team. Deliverables include a demand generation playbook, prospect data, CRM integration and a live dashboard.
Its case studies include 937 appointments with local government for AchieveIt and 298 appointments with managed service providers for Crewhu. The page says clients can cancel at any time.
Prospects choose a monthly band: under $5,000, $5,000 to $10,000 or $10,000 and above.
SalesRoads fits phone-friendly industries with an established pitch. It is a poor match for developer audiences, which tend to ignore cold calls.
Callbox is a B2B lead generation and appointment setting company founded in 2004. It combines AI tools with human specialists across phone, email, LinkedIn, chat, webinars and AI voice agents. Services include outsourced SDRs, account-based marketing and cross-border lead generation.
It lists teams in the US, UK, Australia, Singapore, Malaysia, Hong Kong and Colombia.
Callbox is one of the largest options by reach. It reports 15K+ companies served, 10K+ campaigns and 60+ countries, with an average time to first lead of two weeks. Its AI voice agents handle high-volume calls while human SDRs take the consultative conversations.
Rating figures include 4.4 on G2 and 4.5 on Google. Its page lists a case study of a 14-month account-based campaign that generated 700 appointments for a managed service provider.
Custom quotes based on campaign scope, target market and engagement model.
Callbox works for enterprises that need multi-region coverage and high call volume. A founder-led company with a small, precise target list will use little of that scale.
Martal Group is an outsourced sales and lead generation firm that positions itself for technology and SaaS companies. Its model uses fractional sales reps, and it offers multilingual and multi-region coverage.
Its public materials describe 200+ fractional reps and a tiered engagement model. Martal's site blocked our automated review, so details here come from third-party summaries and may be out of date.
Martal is one of the more visible choices for software buyers. The fractional-rep model lets clients add outreach capacity without hiring, and the multilingual angle helps teams entering new markets.
Review the vendor's own page and ask for references to confirm current services and terms, since our data on it is thinner than for other companies in this list.
Custom quotes. We could not confirm published prices.
Martal suits software companies that need multilingual outreach across regions. Verify the current terms directly before shortlisting.
Leadium is a B2B lead generation and outbound appointment setting firm that provides a done-for-you SDR team. Services include outbound email, cold calling, LinkedIn prospecting, inbound lead qualification, data sourcing and deliverability setup.
It names cybersecurity, SaaS, freight logistics, marketing services and digital transformation among its industries, and it lists CEOs, founders and CROs among its buyers.
Leadium is one of the strongest choices for startup-friendly budgets. Its contact form lists monthly budget options from $2,500 to $3,500 up to $10,000 and above, which signals a lower entry point than most firms here. It promises inbound follow-up in under five minutes.
It claims a 67% reduction in weighted cost against building in-house and a 73% increase in conversations from channel-optimized data. Those figures are self-reported, and its page gives two different totals for clients acquired, so treat the numbers with care.
No prices on the page. The contact form lists budget ranges from $2,500 to $3,500 up to over $10,000 per month.
Leadium fits small teams that want an outsourced SDR function on a modest monthly budget. It offers less strategy depth for founders who want to build the motion themselves.
memoryBlue provides an embedded revenue development team for B2B technology and professional services companies. The team combines SDRs, ADRs and AEs with marketing, recruitment and academy training. It also places reps permanently on a client's own team.
Its site says it works only in B2B and that 85% of the meetings it books come from phone calls.
memoryBlue is one of the largest options by headcount. It lists 650+ dedicated reps, 3,000+ clients, 20+ years in business and 30+ languages across 7 global offices. G2 lists it at 4.6 out of 5 across 300+ reviews.
Its audition-to-hire model lets a client hire a rep onto its own team. It also offers a cost calculator that compares in-house and outsourced SDR costs.
Not published. A cost calculator on its site estimates in-house against outsourced costs.
memoryBlue is a good fit for enterprise technology sellers that want scale and a path to hiring the reps. Early-stage founders with small target lists will not use its full bench.
SalesHive is a B2B sales agency with an AI tool for sales, marketing and operations. It pairs managed cold calling and email outreach, run by dedicated SDR teams, with a project-based AI product.
Services include appointment setting, SDR outsourcing, list building and sales strategy. It lists SaaS, financial services, healthcare, manufacturing and professional services as industries.
SalesHive is one of the more transparent choices on terms. It charges one flat monthly fee that covers the SDR team, a strategist, its AI tool, data and tools. The page states there are no setup fees and no long-term contract, and it bills only after the client approves the strategy.
Most clients launch about three weeks after kickoff. Its case studies report meeting bookings, including 1,440 meetings over four years for a workplace injury management provider. It does not guarantee a set number of meetings.
One flat monthly fee, with the amount shared after a conversation.
SalesHive suits teams that want predictable billing and an outsourced calling team. Founders who need strategy and signal-based targeting should look at embedded options.
UnboundB2B combines content syndication with outbound prospecting, which suits demand generation teams that want both lead sources in one program. It publishes buyer guides on appointment setting.
Our review of its own services page was limited, so details here are drawn from third-party summaries.
UnboundB2B is one of the more distinctive picks because it links marketing-sourced leads to outbound follow-up. That helps teams whose pipeline depends on gated content.
Confirm services, volume and terms with the vendor, as we could not verify current details.
Not published in the sources we reviewed.
UnboundB2B suits demand generation teams that run content-led programs. Founder-led sales teams with a short target list will get more from targeted outbound.
Use these five checks to narrow the list. Each one maps to a question you can put in a vendor call.
Ask whether you pay for booked, held or qualified meetings. CIENCE reports held meetings, and Belkins counts sales-qualified meetings with decision-makers. A booked meeting that never happens still costs your rep an hour.
Write the definition into the contract. Include who qualifies the prospect, which title counts and what happens to no-shows.
Developers, healthcare executives and government buyers each respond differently. SalesRoads and memoryBlue lean on calls, while QC Growth uses signals, email and LinkedIn for technical audiences. Ask the vendor for results with buyers like yours, not averages across 50 industries.
If your market has a few hundred real accounts, outreach quality matters more than send volume. A burned list or damaged domain is hard to undo.
Some vendors keep the data, sequences and playbooks. Others, like QC Growth, hand them over at the end. Ask what you keep if you stop paying and whether you can export contacts, sequences and reporting.
This decides whether the next year costs you another full ramp-up.
Add setup fees, commissions per meeting and any minimum term. Compare the total against the in-house figure of $57k to $81k per month plus equity that QC Growth cites for a senior GTM team. For month-to-month vendors such as CIENCE and SalesHive, factor in the cost of switching.
Request named case studies from companies at your size and in your category. Ask for one reference call. A vendor that has only worked with enterprises will have a different playbook from one that has taken Seed teams to their first enterprise customers.
| Category | Key Considerations |
|---|---|
| Top 3 for early-stage software | QC Growth, CIENCE, Leadium |
| Who Is It For | Founders and sales leaders who need qualified meetings and cannot staff outbound in-house |
| Use Cases | First enterprise deals, new market entry, filling a thin pipeline, testing a new segment |
| How to Choose | Define a meeting, match channel to buyer, check ownership, compare total cost, ask for stage-matched proof |
| Mistakes to Avoid | Paying for booked meetings without a quality definition, ignoring domain health, signing without data ownership terms |
| Pricing Starts | Around $2,500 per month on Leadium's form, with QC Growth packages at $7.5k to $25k per month |
QC Growth builds and runs the outbound system for Seed to Series A technical founders, and you keep the infrastructure, data and playbooks when we finish. The pod includes a GTM operator, a GTM lead, a GTM engineer and BDR support, at $7.5k to $25k per month compared with $57k to $81k per month plus equity for an in-house team.
Read how it worked for Burn Media Co., or see the client quotes from Grafbase, Eraser.io and Crescendo on our case studies page. Founders who want to talk through fit can book a strategy call with Luke Bivens' team.
The best B2B appointment setting company in 2027 for Seed to Series A software teams is QC Growth, because it builds an outbound system you keep instead of renting meetings. For high-volume phone programs, CIENCE, SalesRoads and memoryBlue are stronger fits. CIENCE reports held meetings on a month-to-month basis. SalesRoads launches in 15 business days.
Consider how a company defines a meeting, which channels it uses for your buyer, who owns the system afterward, total cost and proof at your stage. CIENCE reports held meetings and Belkins counts sales-qualified meetings with decision-makers, so the same number can mean different things. Ask for one reference call from a company at your size. Compare the total against $57k to $81k per month plus equity for an in-house senior GTM team.
QC Growth differs from similar B2B appointment setting companies by embedding a pod of an operator, a GTM lead, a GTM engineer and BDR support, and leaving the infrastructure, data and playbooks with you. Most agencies keep the playbook and sell meetings by the month. QC uses signal stacking across firmographics, LinkedIn activity, job changes, hiring, tech stack and web visits. It does not guarantee meeting counts.
Getting started with QC Growth begins with a strategy call booked through qcgrowth.com/contact-us. The team reviews your stage, buyer and current pipeline, then recommends either the GTM Systems and Ops package or the Full Service GTM package. Engagements run 6 to 12 months at $7.5k to $25k per month.
Switching to QC Growth is straightforward because the pod works inside your existing tools and CRM instead of replacing them. You do not need to rebuild your stack first. Because the infrastructure and data are yours, you can also leave without losing the work.
Outsourced appointment setting is worth it for a seed-stage startup when the offer is clear and the buyer list is large enough to test, since the in-house alternative costs $57k to $81k per month plus equity by QC Growth's math. It is a poor match when the target list is only a few dozen accounts, because volume programs can burn that list quickly. Fractional, signal-based outreach protects a small market better. Budgets in this category start near $2,500 per month on Leadium's contact form and reach $25k per month at QC Growth's top package.
The difference between appointment setting and lead generation is that appointment setting delivers a scheduled meeting with a qualified buyer, while lead generation delivers contact details or interest signals. Belkins, Leadium and Callbox sell both. CIENCE and SalesRoads report booked or held meetings. Ask any vendor which outcome the invoice is based on.
