Belkins built its name on appointment-setting for mid-market B2B. Great fit for teams with an in-house closer and a big enough deal size to feed an agency retainer. Not the right shape for lean founders who want one accountable operator on the pipeline, or teams that need CRM hygiene and inbound follow-up alongside outbound. Here are the 7 alternatives I recommend most.
Fractional SDRs + AEs, lead gen, and pipeline development.
Best for: Tech companies wanting fractional sales teams
Pricing: Monthly retainer, tiered
One senior remote SDR/AE operator running outbound + follow-up + CRM hygiene inside your stack, on a monthly retainer.
Best for: Founders and lean teams who want one senior person running sales, HR, payroll, or ops inside their stack - not a platform ticket queue.
Pricing: Monthly retainer, part-time or full-time - one predictable fee, no per-seat markups.
Managed lead gen, SDR teams, and AI-augmented prospecting.
Best for: Multi-channel outbound at scale
Pricing: Monthly retainer, quote-based
Outsourced cold calling and appointment setting.
Best for: US-focused appointment setting

On-demand callers for lead qualification and appointment setting.
Best for: Ad-hoc outbound calling campaigns
Pricing: Per-call or campaign pricing

An agency is right when you need volume - five sequences, dozens of accounts a week, formal reporting cadence. One senior operator is right when you need quality, ownership, and CRM discipline - the same person on every call, working inside your systems. Different tools, different jobs.
Upcall and per-project engagements with me start at roughly a third of a full agency retainer. That trade-off is real: less volume, more ownership. Belkins, CIENCE, and Martal are priced for teams already at $50k+/mo revenue.
Yes - this is common. Belkins books meetings, I handle everything after the meeting is booked: CRM update, follow-up sequences, deal-desk paperwork, and reporting into your close-rate metrics.
Apollo.io bundles contact data + sequences + dialer into one seat, which is why lean sales teams adopt it. The alternatives below trade that bundling for specific strengths: better EU data, deeper sequencing, or lower per-seat cost. Pure-software list - I'm the person who uses these tools, not a replacement for them.
Traditional outsourcing agencies solved one problem - bench depth - by creating three others: rotating operators, an account-manager layer, and a margin stack that scales faster than the work. If you're a founder or ops lead with under 50 employees, this list is the shortlist I actually recommend.
You saw where I fit on this list. Book a call and I'll come back with a scoped plan for your workflow within 48 hours.
