Astounding ROI Right Out of the Gate
Imagine boosting your sales pipeline nearly 10x. Sounds like a pipedream, right? Especially for an established brand like Greenhouse, already thriving with numerous mid-market and enterprise clients. Yet, that's precisely the feat Greenhouse's outbound team achieved when they partnered with Nooks.
We spoke with Mariah Donnelly, Greenhouse’s talented Senior Director of Global Sales Development, about the remarkable ROI her team achieved through cold calling with Nooks. Their cold-call pipeline exploded by an incredible 933%, and revenue from cold-call-generated leads surged by 550%. According to Mariah, these extraordinary results alone made partnering with Nooks an undeniable success.
But how exactly did they make it happen?
The Backstory: Facing a Tough Outbound Market
Before partnering with Nooks, Greenhouse had already established itself as a leader in hiring technology. They had built a growth engine that consistently delivered results and were eager to unlock new revenue opportunities.
Email had proven highly effective as their primary outbound channel—but as Greenhouse scaled, they recognized untapped potential in leveraging the phone to drive even greater impact.
Previous dialing solutions that Greenhouse tried out never got the adoption needed to drive real results, leaving reps not dialing and a hard to justify line item in their tech stack budget Calls weren’t made consistently and enthusiasm for the channel was fading. Recognizing the urgent need to shift gears, Nicole Osborne—a proactive frontline manager at Greenhouse—took the initiative to explore new solutions, ultimately leading Greenhouse straight to Nooks.
Why Nooks Won Greenhouse Over
After Nicole had shown Mariah what Nooks was all about and how it was different from other dialers on the market, Mariah began to see the potential value. But what neither Nicole or Mariah anticipated was just how fast and how dramatic the positive impact would be. Leading up to the trial, the Nooks Account Executive remarked that a pretty significant lift in cold call success could be seen within a few weeks. As it turned out, even that estimate was conservative—the real results were immediate, impressive, and tangible within just the first few days:
- 7x increase in connects in just the first three days compared to the week before
- 4x increase in prospect talk time
- 4x the dials compared to their previous efforts
Mariah and the team saw immediate confidence boosts among reps. The difference was clear during "power hours," with reps jumping from 2 connects per hour to 9—talk about energizing results!
Their Favorite Part: The Coaching Bot
While the lift in pipeline was all the proof Greenhouse needed to keep going with Nooks, the feature that truly won over hearts (and sparked excitement across the team) was something entirely different: the Nooks AI Coaching Bot. Introduced during an energetic offsite, the bot quickly became a hit, transforming onboarding by making reps "field-ready" faster than ever before.
The Coaching Bot allows sales teams to build custom scenarios around specific buyer personas, letting them practice live cold calling situations in a realistic, risk-free environment. This means new SDRs can confidently hone their pitch, refine objection handling, and master their cold-call scripts—all before ever speaking to a real prospect.
It even became a fun "party trick," impressing execs and building team-wide enthusiasm. Mariah humorously recalls how even their executives used the Coaching Bot to book meetings—earning serious "street cred" internally.
Creating a Collaborative Cold-Calling Culture
Nooks didn't just boost metrics; it reshaped Greenhouse’s sales culture. Cold calling went from solitary and daunting to collaborative and dynamic. Virtual "power hours" became lively events with reps cheering each other on, celebrating wins, and learning together.
Mariah noted the remarkable energy shift: "It's a huge difference when you’re making calls together versus alone."
Final Thoughts
Thanks to Nooks, Greenhouse transformed their cold-calling approach, achieving unprecedented pipeline and revenue growth. More importantly, they created an environment where SDRs could thrive, collaborate, and succeed together. It also has to be noted that none of this could have happened without the willingness to adapt by Mariah and other Greenhouse leaders, as well the drive to succeed that they instilled in their teams.
As Mariah puts it, "Nooks fundamentally elevated our outbound sales game—and we’re just getting started."
