Belkins is a great appointment setter. SalesGlider is your growth partner.
You've probably worked with an agency that took your retainer, sent a batch of emails with your name on them, booked you a handful of meetings with people who had no idea why they were on the call, and disappeared. That's not us - and frankly, it's not Belkins either. But there's still a meaningful difference between an agency that books meetings and a partner that builds your revenue engine with you.
Belkins will assign you an SDR team, build a list, and start booking meetings. They're good at it. What they won't do is sit down with you and pressure-test your ICP, refine your offer angle, or build a coordinated outbound strategy that adapts based on real market signals - across cold email, cold calling, and LinkedIn as one connected system.
That's the SalesGlider difference. We don't just execute - we collaborate. Your strategy, your messaging, your offer, and your market are all inputs we work on together before a single email goes out. Then we run a coordinated, signal-based outbound system across every channel, connect every touchpoint, and report back on what's winning so we can do more of it.

Strategy before execution
We don't just take a brief and start dialing. We work with you to sharpen your ICP, stress-test your offer, and identify the approach most likely to work in your specific market - before a single email goes out.
Strategic depth
We bring years of outbound experience and adapt based on real market signals - hiring intent, competitor activity, content engagement, website visits. Our approach evolves weekly because your market does too.
One coordinated system
Cold email, cold calling, and LinkedIn aren't three separate campaigns at SalesGlider - they're one connected revenue motion. Belkins runs channels in parallel. We run them as a unified engine.
You pay for results
Our performance fee is tied to meetings booked and held. Belkins charges a retainer from day one regardless of output.
The best intro offer
Our 60-day sprint gives you 5 qualified meetings with no long-term commitment. Belkins requires a retainer before you've seen a single result.
Brand recognition
Belkins has 200+ employees, 1,000+ clients, and hundreds of verified reviews. If you need to justify a vendor choice internally, their name carries weight that SalesGlider is still building.
Deliverability platform
Belkins built Folderly, a proprietary email deliverability tool. Our infrastructure is equally strong, but it's not a public-facing branded product with its own reputation.
Larger SDR team
More operational redundancy for very high-volume enterprise campaigns.
Belkins is a solid appointment-setting agency. SalesGlider is a growth partner that collaborates on strategy, runs a coordinated signal-based outbound system across every channel, and ties every dollar to a meeting that actually happens. If you want an agency to execute your playbook, Belkins works. If you want a partner to build one with you - start with our 60-day sprint.
Most lead gen shops take your retainer, work a list, and hand you a calendar invite. SalesGlider collaborates on your strategy, runs a signal-based customer acquisition system across cold email, LinkedIn, and website design - with no long-term contracts, so the risk is on us.
