Since its founding in 2021, LevelUp Leads has grown to support over 70 clients with a scalable, data-driven approach to SDR-as-a-service. The company runs a full spectrum of outbound for its customers, from building infrastructure and sourcing data to dialing at scale and, ultimately, booking meetings that move the needle.
”We’re relieving the operational headache of having to hire and manage SDRs, including all the tools like data platforms, auto-dialers, and email automation,” says Founder and CEO John Karsant. “It’s a plug-and-play system that a lot of companies can use to go out and test the market.”
And it’s working. With a growing team, an in-house platform for client reporting, and a high-volume outbound engine making over 30,000 cold calls per day, LevelUp Leads has turned cold calling into a competitive edge.
One of the key factors to their success is strong data. And ZoomInfo is central to that strategy.
Once we started using ZoomInfo, we saw a jump in connect rates, which for us at our volume is huge. Even a small bump in connections is huge when we’re making roughly 30,000 calls a day. And that creates even more opportunities for our team to pitch our clients’ services or products.

Data Became Critical as Cold Calling Took the Lead
LevelUp Leads specializes in helping clients test new markets, launch new products, or expand sales capacity without building a team from scratch. The company includes everything from reps to tools, so that clients can simply say “go.”
“Our biggest use cases are for companies entering the U.S. market, or trying to scale fast without hiring in-house,” Karsant explains.
Cold calling wasn’t always part of LevelUp Leads’ offering. The company started with list building, email, and LinkedIn outreach. But after about a year, they began testing calls. And the results were undeniable.
Today, cold calling represents the core of the company’s value proposition — and that makes data quality more critical than ever.
“We’re always looking for ways we can give our sales reps the most opportunities to connect and have conversations with people,” Karsant says. “Right now, cold calling is our clients’ most in-demand service. And that means that data is really important for us.”
That shift was part of the reason LevelUp Leads brought on ZoomInfo: to ensure their reps had the highest-quality data powering every dial.
10,000 More Conversations: How Better Data Drove Better Results
LevelUp Leads has used multiple sales intelligence providers to give its clients the most opportunities. In 2023, they adopted ZoomInfo as part of an effort to boost connect rates and improve efficiency across campaigns. The shift paid off.
“Once we started using ZoomInfo, we saw a jump in connect rates, which for us at our volume is huge. Even a small bump in connections is huge when we’re making roughly 30,000 calls a day. And that creates even more opportunities for our team to pitch our clients’ services or products,” Karsant says.
Just how big was that jump? ZoomInfo helped LevelUp Leads achieve:
10,000 more live conversations daily
A reduction of 222 dials per meeting booked, making the team nearly 20% more efficient
“The more dials we're making, the more connects we're having, the more meetings we're able to set,” Karsant says.
And ZoomInfo has brought more value than simply cold call connects.
For LevelUp Leads, ZoomInfo turns outbound strategy into action. When onboarding new clients, the team leans on ZoomInfo to define TAM (total addressable market), evaluate viable titles, and shape go-to-market plans.
“It’s our go-to tool,” Karsant says. “We’ll open ZoomInfo first.”
