Last updated: May 2026

Top picks at a glance: Belkins leads on appointment setting with email and LinkedIn outreach. Martal Group handles multichannel campaigns for tech companies. Callbox offers global coverage with two decades of B2B experience. Most alternatives run $3-10k/month compared to CIENCE's $5-15k/month, with shorter contract terms.

CIENCE Alternatives Comparison

Belkins

Belkins specializes in appointment setting through email and LinkedIn outreach. Founded in 2017, they've built a reputation for high deliverability and consistent meeting rates. Their focus is narrower than CIENCE but execution is tight.

Skip the Agency. We'll Build Your Outbound System.

The agencies above charge $5-15k/month for SDRs you don't control. You get meetings, but you don't see every message going out, can't iterate on messaging in real-time, and start from zero when the engagement ends.

Miniloop takes a different approach: we build your outbound system from scratch. List building, enrichment, sequencing, signal monitoring. set up and running in weeks, not months.

The difference: you own it. Full visibility into every message. Change anything instantly. And when you're ready to run it yourself, the system stays with you.

We're working with a handful of companies right now to build their outbound systems. Get in touch if that's you.

CIENCE offers a broader platform including proprietary intent data (GO Data) and managed SDR teams. Belkins focuses specifically on appointment setting through email and LinkedIn. CIENCE costs more but provides more infrastructure. Belkins is leaner and often delivers faster time-to-meeting with lower minimums.

Do any CIENCE alternatives offer performance-based pricing?

Leadium offers some performance-based options where you pay per meeting booked. Most agencies blend retainer fees with performance bonuses rather than pure pay-per-meeting models.
