When Belkins is the right call

  • You're closing enterprise deals ($100k+ ACV) that need a dedicated human SDR making calls
  • You can commit to a 6-month contract and have budget for $5k+/mo
  • You want a proven, large agency with deep Clutch social proof
  • Your product requires significant discovery conversations before a demo makes sense

When Stellar Digital is the right call

  • You want automation that runs without adding headcount to the org chart
  • You need flexibility — month-to-month, not a 6-month lock-in
  • You want to own the outbound infrastructure so it doesn't disappear when you stop paying
  • You're at an earlier stage and need to move fast without enterprise-level spend
  • You want a tech-forward system that improves over time, not a human process that plateaus

What actually sets Stellar Digital apart

You own the infrastructure

With Belkins, the SDR team, the sequences, the tools — they all belong to Belkins. When the contract ends, you start from zero. With Stellar Digital, the domains, campaign flows, contact databases, and workflows are yours. The system keeps working after the engagement ends.

Automation vs. headcount

Belkins scales by hiring more SDRs. Stellar Digital scales by improving automation. The result: a Stellar Digital system can run 5x the volume of a Belkins engagement at the same budget, because there are no labor costs baked into every additional contact.

Flexibility on contracts

Most companies aren't ready for a 6-month commitment when they're testing outbound. Stellar Digital offers month-to-month arrangements after an initial setup period, so you can validate the channel before you're locked in.

Speed to first meeting

Belkins typically takes 4–6 weeks to onboard a client and launch a campaign. Stellar Digital averages 2–3 weeks from signed agreement to first campaign live — and first replies often come within the first two weeks.

Frequently asked questions

Is Belkins worth the price?

Belkins charges $3,000–$10,000/mo and delivers via manual SDR teams. For enterprise deals where human relationship-building matters, the price can be justified. For companies under 50 employees or with deal sizes under $50k ACV, automated outbound typically delivers better ROI.

Does Belkins have long contracts?

Yes. Belkins requires a minimum 6-month commitment in most engagements. This is standard for large agencies that need to recoup SDR onboarding and ramp costs. Stellar Digital offers month-to-month after an initial setup fee.

How does Stellar Digital compare to Belkins on results?

Results depend heavily on ICP, offer, and market. Stellar Digital clients have seen 200+ qualified appointments in 60 days. The structural difference: automation allows more volume, faster testing, and lower cost per meeting.

What happens to my campaigns if I stop working with each agency?

With Belkins, campaigns stop — the SDR team and tools belong to them. With Stellar Digital, you retain all infrastructure: domains, sequences, lead lists, and workflow automations. You can continue running them independently or hand them to an in-house hire.
