Find out why our solution is the top choice for high performing sales teams

"Zell dramatically improved how we onboard and train SDRs and AEs. Reps use it daily to practice calls, and managers can scale coaching without extra effort. The platform has massive potential, and the team behind it is exceptionally responsive"

Anthony Ward

Director of Growth-Marketing

"Zell’s simulated interviews are an added value compared to the traditional recruitment and selection process; they allow us to further validate candidates’ suitability against the client’s specific requirements and characteristics, thereby reducing the risk of turnover and increasing our clients’ level of satisfaction."

Marina Longobardi

Consultant, Certform

"For us, fast SDR onboarding is critical. We’re constantly starting new projects, and Zell lets new reps get productive in days instead of weeks"

Julius Dany

CEO, Revenue Excellence Partnes

"We use Zell to improve our cold calling methods in the business development team. It is useful to clarify the architecture of the call and its founding elements, from the PBO to the Scheduling Meeting. Practice makes perfection, and with Zell we don’t have to put any real contact at risk. We even did a Zell tournament (same structure as with Italian football) and was super fun!"

Jacobo Ferro

Head of Sales, Omnisyst

"Zell helped us reduce time to first sale from 180 to 105 days. We also use it during hiring to assess how candidates actually sell, not just how they interview."
