TL;DR: Belkins has strong reviews (4.8 on G2, 4.9 on Clutch) and a solid track record with 200k+ appointments booked. But expect premium pricing ($5k-14k/month), some inconsistency in campaign execution, and a 3-6 month commitment. Best for B2B companies with $10k+ monthly budgets who want white-glove appointment setting.
Belkins Reviews 2026: What Clients Actually Say About This B2B Agency
Last updated: May 2026
Belkins is a B2B appointment setting agency founded in 2017. They run email and LinkedIn outbound campaigns for clients, handling lead research, messaging, and appointment booking. The company claims 200k+ appointments scheduled for nearly 1,000 clients. But what do actual customers say? This review breaks down ratings across major platforms, common praise, recurring complaints, and who Belkins works best for.
Overall Ratings Across Platforms
Belkins has strong aggregate scores across the major review platforms.
| Platform | Rating | Review Count |
|---|---|---|
| G2 | 4.8/5 | 89+ reviews |
| Clutch | 4.9/5 | 230+ reviews |
| Trustpilot | Mixed | 7 reviews |
| TrustRadius | 4.5+/5 | 20+ reviews |
| Gartner Peer Insights | 4.5/5 | Limited reviews |
The Clutch profile is their strongest. Belkins ranks 5th on Clutch's Top 1,000 Global Service Providers list and has held the #1 appointment setting company ranking for five consecutive years.
The Trustpilot presence is thinner with mixed feedback. With only 7 reviews, it's not statistically meaningful, but the negative reviews there are worth noting for the specific complaints they raise.
What Clients Praise About Belkins
Across platforms, several themes emerge from positive reviews.
Lead Quality and Research
Clients consistently highlight Belkins' research capabilities. The team manually verifies leads rather than relying purely on database pulls. Reviewers mention that Belkins identifies suitable leads through extensive market research and provides detailed ICP and TAM mapping.
One G2 reviewer noted that Belkins transformed their outbound process by handling research, messaging, testing, and scheduling. Another mentioned securing quality meetings and closed deals thanks to an organized and transparent approach.
Communication and Transparency
Multiple reviews call out the communication quality. Belkins provides 24/7 dashboard access, records all calls, tracks every email send and response, and maintains regular meeting cadences with clients.
Clutch reviews highlight that approximately 90% of reviewers commend their expertise in handling outbound processes independently. The team's responsiveness and willingness to adjust campaigns based on feedback comes up repeatedly.
Results and ROI
Belkins claims a 10:1 average ROI and 25% average closing rate across industries. Specific client results cited in reviews include:
- A SaaS company seeing 137 qualified demo bookings leading to 12-13 monthly appointments
- An adtech firm booking 78 relevant appointments in six months
- An e-commerce development agency securing 15 qualified appointments in three months
Professionalism
Reviewers describe the team as professional, easy to work with, involved, supportive, and always ready to help. The structured onboarding process and dedicated account manager model get positive mentions.
Common Complaints About Belkins
No agency is perfect. Here's what dissatisfied clients point to.
Premium Pricing
The most common concern is cost. Belkins charges $5,000-$14,800/month with 3-6 month minimum commitments. Some sources cite $300-$800 per booked appointment. For budget-conscious startups, this is a significant investment.
Onboarding fees add $2,000-$5,000 depending on ICP complexity. The total first-year cost can easily exceed $70,000 for a full engagement.
Inconsistent Execution
Some negative reviews describe campaigns that underdelivered. One Trustpilot reviewer reported not seeing any good leads despite being promised a specific monthly count. Another mentioned that their assigned team lacked expertise in their specific industry (SaaS/CRM) despite Belkins advertising experience there.
The quality variance appears tied to account manager assignment. Some clients get senior, experienced teams. Others get junior staff following playbooks without deep domain knowledge.
Lead Quality Mismatches
A few reviews mention leads that didn't match the Ideal Customer Profile. When campaigns rely on basic open data sources, it's easier to generate volume than quality. Some clients felt pushed to accept leads that weren't genuinely qualified.
Sales Pressure During Onboarding
Multiple reviewers mention intense pressure to sign contracts. The sales process can feel aggressive, with strong pushback when prospects try to slow down or ask more questions.
Service Department Responsiveness
Post-sale, some clients report difficulty getting issues resolved. Reviews mention being ignored or passed between team members without resolution. This contrasts with the communication praise from satisfied clients, suggesting inconsistency across accounts.
Run outbound on autopilot.
Lead lists, enrichment, ICP qualification, personalized openers, sequencer push. Miniloop runs the loop, you take the meetings.
Best For: Who Belkins Works Well For
Belkins is a strong fit for certain company profiles.
Established B2B companies with $10k+ monthly budgets. If $5,000-$15,000/month is within your lead gen budget and you can commit for 3-6 months, Belkins delivers at scale.
Teams needing white-glove service. If you want an agency that handles everything (research, messaging, testing, booking) with minimal input from your team, Belkins does that well.
Companies targeting common B2B verticals. Belkins has deep experience in SaaS, professional services, IT, manufacturing, and technology. Their playbooks work best in established categories.
Organizations that value transparency. The detailed reporting, call recordings, and dashboard access appeal to teams who want full visibility into campaign performance.
Not Best For: Who Should Look Elsewhere
Belkins isn't the right fit for everyone.
Early-stage startups with tight budgets. At $5k-$14k/month plus onboarding, Belkins is expensive for seed-stage companies still validating product-market fit.
Companies in highly technical or niche verticals. If your ICP requires deep domain expertise (biotech, fintech regulations, etc.), the generalist agency model may not produce quality leads.
Teams wanting AI-driven optimization. Belkins relies on manual processes and human SDRs. If you want advanced AI automation, real-time deliverability optimization, or programmatic campaign adjustment, newer competitors offer more.
Organizations needing short-term campaigns. The 3-6 month minimum commitment doesn't work for companies wanting a one-month test or short-term project.
Belkins vs Competitors
How does Belkins stack up against other appointment setting agencies?
| Company | Pricing | Approach | Best For |
|---|---|---|---|
| Belkins | $5k-$14k/mo | Manual research + email/LinkedIn | White-glove B2B appointment setting |
| CIENCE | Similar to Belkins | Multi-channel outbound | Historically strong, recent quality decline reported |
| Martal Group | Starting $4.5k/mo | Global SDR teams | North American + international markets |
| SalesRoads | Custom | Phone-heavy, US-based SDRs | Cold calling campaigns |
| SalesHive | Varies | Hybrid human + tech | Teams wanting more automation |
Belkins vs CIENCE: Belkins consistently ranks higher in recent reviews. Multiple sources note that CIENCE's results no longer match competitors like Belkins, Callbox, and Martal Group.
Belkins vs Martal Group: Martal starts slightly lower ($4,500/month) and has stronger international coverage. Belkins edges Martal on Clutch ratings and US-focused campaigns.
Belkins vs SalesRoads: SalesRoads emphasizes phone over email. If your ICP responds better to calls than cold emails, SalesRoads may be the better fit. Belkins wins on email and LinkedIn execution.
Real Client Feedback Themes
Looking across hundreds of reviews, certain patterns emerge.
The 90/10 split. Approximately 90% of Clutch reviews are positive. The remaining 10% cite specific execution failures. This suggests Belkins delivers well most of the time, but some campaigns fall short.
Account manager dependency. Your experience often depends on who gets assigned to your account. Senior, experienced managers produce better results than junior staff. Ask about team assignment during sales conversations.
Ramp-up period. Multiple reviews mention it takes time for campaigns to hit stride. Expect 1-2 months of testing and iteration before seeing consistent appointment flow.
Held meetings vs booked appointments. Some reviews note a gap between booked appointments and held meetings. Ask Belkins about their held rate metrics, not just booking numbers.
Renewal pressure. As contracts approach expiration, expect pressure to renew. Some clients felt rushed into renewals before having complete data on campaign performance.
How Miniloop Compares
Belkins gets mixed reviews on execution consistency. Some campaigns deliver. Others fall short of expectations. The account-manager-dependent quality and premium pricing create risk for budget-conscious teams.
Miniloop takes a different approach. Instead of outsourcing outbound to an agency, you run campaigns in-house with full visibility into every step. Miniloop handles the busywork that makes outbound tedious: scraping leads, building lists, enriching contacts, drafting personalized messages, and pushing to your sequencer.
You keep control of messaging and targeting. You see exactly what's being sent. And you're not locked into 6-month contracts with $5k+ monthly minimums.
