Structural revenue consulting

Revenue systems fail
long before leadership sees it.

We help founder-led and PE-backed companies between $5M and $100M find where revenue is breaking, rebuild the system underneath it, and make growth predictable.

The Engine, explained

Why revenue breaks, and how the diagnostic finds it.

The Sales Lab Engine™, the five pillars, and what the free Revenue Diagnostic shows you. Narrated by founder Reza Nazarinia. Eighty five seconds.

Revenue Diagnostic

A structured intake that scores all five pillars of your revenue engine and shows where it leaks and what it costs. Complimentary. We run a limited number each quarter, and Reza reviews every one personally with his team. The Sales Lab is a private advisory firm and takes on a small number of engagements at a time, in confidence.

Built in real operating environments

Operator experience, not theory.

Built and run by an operator who carried the revenue number for more than two decades across MedTech, medical devices, and industrial services. Not theory from a slide deck.

Revenue does not become predictable by chance.
It is designed.

The work is structural: diagnosis, redesign, and enforcement, so leadership can run the business with clarity.

What we do

Diagnose. Rebuild. Enforce.

01

Diagnose

We find where the pipeline breaks, why the forecast misses, and where leadership loses visibility.

02

Rebuild

We redesign the revenue system: pipeline structure, accountability, forecasting discipline, and execution cadence.

03

Enforce

We install dashboards, KPI governance, leadership rhythm, and operational accountability so revenue performance becomes measurable, scalable, and less dependent on individual heroics.

How it works

From first read to predictable revenue

Thirty six questions, about ten minutes. Free.
02

03
Roadmap
A review session turns the findings into priorities across the five pillars.
04
Implementation
We rebuild the system, pillar by pillar, until growth holds without heroics.
The Methodology

Revenue is a science.
This is the system.

The Sales Lab Engine™ measures and rebuilds the five structures that decide whether revenue is predictable: Predictability, Pipeline, Management, Technology, and Growth.

THE SALES LAB ENGINE™

Five pillars. One core. When any pillar weakens, the whole engine leaks revenue. The diagnostic measures all five and shows you exactly where.

The line we hold

This is not sales consulting

Not training

We do not run workshops to motivate activity. Activity is not a strategy.

Not coaching

We do not coach the team while the system stays broken.

Not hiring-first

We fix structure so hiring actually works.

Trigger points

When companies bring us in

Leadership lacks confidence in forecasting and pipeline visibility

Forecasts stop matching reality

Pipeline volume increases while conversion quality declines

Revenue performance becomes dependent on a small number of individuals

Growth exposes operational weaknesses leadership cannot yet see

Sales activity exists without execution accountability

Expansion creates friction across teams, territories, and reporting structures

We work with a small number of companies at a time, from $5M in revenue up. We take the engagements where the structural work returns the most.
