The challenge

Greenhouse, a hiring-software company, had built a growth engine led by email but saw untapped potential in phone outreach as it scaled. Previous dialing tools never achieved the adoption needed to drive results, leaving reps dialing inconsistently and the tool hard to justify in the budget.

The solution

Greenhouse adopted the Nooks AI Dialer and AI Coaching Bot, using custom roleplay scenarios to make reps field-ready faster and virtual 'power hours' to turn cold calling into a collaborative, high-energy activity.

We increased our pipeline—in revenue dollars—by 933%. Additionally, we boosted closed revenue from opportunities originating from cold calls by 550%.

In the first three days, connects increased 7x and both dials and prospect talk time increased 4x, with reps moving from 2 to 9 connects per hour during power hours.
