About The Sales Lab

Most revenue systems break under pressure.
We rebuild them to hold.

The Sales Lab partners with founders, CEOs, CROs, and PE-backed teams to diagnose what’s limiting growth and rebuild a predictable, scalable revenue system. No heroics. No “more activity.”

Most organizations wait too long to fix their revenue system. By the time they act, growth has already stalled.

Why we exist

Effort is not the problem.
Structure is.

Most organizations do not struggle because of effort. They struggle because the revenue system is not built to perform under pressure.

When pipeline becomes inconsistent, forecasting becomes unreliable, and execution becomes reactive, the issue is rarely talent. It is structure.

Fixing revenue is not about pushing harder. It is about redesigning how revenue works.

An operator, in his own words

Reza Nazarinia on why The Sales Lab exists, and what he saw inside two decades of revenue leadership.

Reza Nazarinia

Reza Nazarinia, Founder of The Sales Lab

Reza has carried the revenue number for more than two decades, as an operator, not an advisor. He has led revenue redesign and go-to-market execution inside MedTech, medical devices, and industrial services, across growth-stage and enterprise organizations in Canada and the United States.

He grew a customer base from two to more than two thousand, building it into a national operation of roughly $25M, and lifted forecast accuracy 40 percent through pipeline redesign. He has led revenue through acquisitions, integrations, and multiple stages of scale.

His work is not sales training. It is a redesign, at the leadership level, of how revenue is created, measured, and managed, so growth becomes predictable. He is the author of The Sales Lab, and the Engine is calibrated against more than 50 verified studies. That system now has a name: The Sales Lab Engine™.

“The Sales Lab helped us see the revenue model clearly—what was working, what was breaking, and what to fix first. The result was a cadence we could run and a forecast we could trust.”
