Sustainment is a sales-driven organization where outbound calling plays a critical role in pipeline generation. Business Development Reps are responsible for high-volume outreach, list management, follow-ups, and continuous performance optimization.
We spoke with Dustin Stelton, Business Development Representative at Sustainment, about how Salesfinity transformed his outbound execution by giving reps more control, visibility, and scale.
The challenge
Before Salesfinity, Dustin had experienced two very different outbound setups, neither of which fully supported high-performance sales execution.
At his first role, the team used a dialer, but reps had limited control over how it was configured.
“The reps had no agency, no customization over what they wanted. Everything was in the director’s hands, and that’s not really their role when they have a million other tasks.”
At his most recent role before Sustainment, the situation was even more restrictive.
“That was all manual dial, punching in the numbers myself. I was lucky if I could get 40 to 50 dials in a day.”
Both setups constrained output, slowed feedback loops, and made it difficult for reps to take ownership of their performance.
The solution
Salesfinity introduced a fundamentally different dynamic by putting control directly in the hands of the rep.
Instead of relying on leadership to adjust tooling, Dustin could customize his own dialing setup in real time.
“What’s really nice with Salesfinity is that it gives the actual rep the agency to go in and customize their view and how they want to work.”
At the same time, Salesfinity replaced manual dialing with true high-volume execution.
“Here, I can push 400 to 600 dials easily in a day.”
This combination of autonomy and scale immediately changed how Dustin approached outbound.
The impact
The increase in dial volume was obvious, but the more meaningful shift came from visibility into performance.
Salesfinity made connect rate a first-class metric, something Dustin had never had access to before.
“You guys track connect rate, which is awesome. We never tracked it at my last company, so just doing the most basic thing, you’re already leagues ahead.”
Beyond tracking, Salesfinity surfaced actionable insights at the rep level.
“It shows you the actual connect rates for specific numbers when you load multiple numbers, so you can make decisions in real time. If I see a number has a 2% answer rate, I’ll switch it out because it might be flagged as spam.”
This gave Dustin immediate feedback loops instead of delayed, manager-driven analysis.
Workflow transformation
Salesfinity fundamentally changed Dustin’s day-to-day workflow by allowing him to stay in motion while staying informed.
“I can let the dialer rip and at the same time study on my second monitor, look up what the company does while I’m dialing them.”
By removing manual steps and reducing context switching, speed became the defining advantage.
“It all comes down to speed. How quickly and how many calls can I get in a day?”
Salesfinity enabled a mass outbound approach without sacrificing preparation or focus.
“I can basically power or parallel dial all day.”
Follow-up and integrations
For follow-ups, Dustin relies heavily on Salesfinity’s Nurture AI tasks to reduce CRM back-and-forth.
“The less clicks and the less flopping back and forth between our CRM and Salesfinity, the better for me.”
He also highlighted the ease of integrations with core tools.
“Connecting things like Slack and HubSpot takes seconds. That’s just less cumbersome for me.”
This tight integration helps keep outbound execution centralized and efficient.
Why Salesfinity
For Dustin, Salesfinity stands out as a tool that combines scale, flexibility, and rep empowerment.
“I’d recommend it to companies that want to put customization in the rep’s hands, integrate easily with major CRMs, import lists quickly, and then get straight to calling with centralized performance data.”
What matters most is that Salesfinity supports sustained, high-output execution.
“If you want to give your sales team the ability to make the maximum number of dials, Salesfinity is going to do that.”
