Consulting services

Close the gap between activity and results.

Lewis Lab delivers structured 30-day diagnostics and targeted performance consulting for established private businesses. We review your data and processes, identify where revenue, leads, time, or capacity are leaking, and define what to do about it.

Execution support

The free Clarity Diagnostic is a 12-question self-assessment. A consulting diagnostic is a separate engagement that reviews your actual operating data and processes.


Find what is leaking. Prioritize what matters.

The review follows the path from demand to business results. We examine how marketing activity, customer inquiries, staff processes, and reporting connect, then identify the points that need closer attention.

The initial 30-day diagnostic starts with your business priorities. We agree on the areas to review and the relevant systems and information before work begins. The review can draw on the following areas, depending on the scope:

  • 01 Marketing, sales, and operating data review
  • 02 Lead response and conversion analysis
  • 03 Inventory, capacity, utilization, or throughput assessment
  • 04 Team process and hand-off mapping
  • 05 Market positioning and performance benchmarking

The output connects each priority to an observed issue and a recommended next step. Your team should be able to see what needs attention, why it matters, and how to follow progress.


If any of this sounds familiar, it is worth a look.

Leads are coming in, but conversion is weak

Response times are inconsistent across teams or locations

Marketing reports show activity, but not business impact

Inventory, capacity, or service throughput is limiting growth

Teams are working hard, but process hand-offs are breaking down

Vendors are reporting performance, but leadership lacks a clear read


The common thread is not the industry.

Lewis Lab works with owners and operators of established businesses, including those with multiple locations, departments, service lines, or revenue streams. The common thread is performance that is not matching the effort, spend, or opportunity.

Industry examples include healthcare operations, professional services, and automotive retail. The scope follows the business problem and the operating data available.

You might be a fit if This is probably not for you if
Revenue is flat, inconsistent, or underperforming despite real demand You want a generalist agency to run campaigns
You have useful data, but no clear operating plan based on it You are looking for a long-term retainer with no defined outcome
Conversion, lead response, throughput, or hand-offs are known weak points You are too early-stage to have meaningful lead, sales, or operational data
You run multiple rooftops, locations, departments, or service lines You want a report that confirms existing assumptions instead of challenging them

Experience behind the advice.

Lewis Lab is led by Michael Lewis, whose work at General Motors combined market analysis, dealership process reviews, and commercial planning across independently owned businesses.

He co-developed a planning tool used across the Buick GMC Western Region, connecting each dealership's sales, inventory, and market opportunity to stocking and marketing decisions. During COVID, he also worked with GM's operations team on a nationally distributed Remote Selling Process Map.

That experience shapes the consulting work: establish what the records support, make the commercial choices clear, and develop a plan the people responsible can put into practice.

  • Direct work with Michael from diagnosis through follow-up
  • Findings grounded in operating records and observed processes
  • Priorities matched to business impact and your team's capacity
  • Clear ownership and measures for implementation

Common questions.

How is the free Clarity Diagnostic different from consulting?

The free tool is a 12-question self-assessment. It provides a score and suggested focus area based on your answers. The consulting diagnostic is a separate 30-day engagement that reviews actual operating data and processes within an agreed scope.

What industries does Lewis Lab work with?

Lewis Lab works across industries with established businesses, including healthcare operations, professional services, and automotive retail. Fit depends on your priorities and available operating data, whether the work involves marketing, reporting, conversion, capacity, or team handoffs.

How long does an engagement typically take?

The initial consulting diagnostic runs 30 days. Strategy and execution support can then be scoped around what the review finds and what your team needs.

Do you need access to our internal systems?

Read access to relevant systems or agreed data exports is typically needed. Depending on the scope, that may include a CRM, DMS, lead management platform, or reporting dashboard. We agree on the scope and information needed before the review begins.

Who will I work with?

You work directly with Michael Lewis. Lewis Lab is a founder-led practice, with the same person involved in understanding your operations and developing the recommendations.

How is this different from hiring a fractional COO or internal analyst?

A fractional COO generally takes on ongoing management responsibilities. Lewis Lab provides an independent assessment of agreed business areas and performance priorities, followed by a practical action plan. Further strategy or execution support is scoped separately.
