One constraint. One quarter.

A better way to run the work.

EC90 is a focused business transformation led directly by Jeffrey and Corey Mack. Leadership chooses one company-level constraint, one accountable sponsor, and one measurable finish line for the quarter.

Apply for EC90

Starting investment: $75,000 total, inclusive of an eligible credited diagnostic.

One quarter from shared truth to installed change.

The direct answer

Transformation fails when diagnosis, strategy, implementation, and adoption are split apart.

EC90 keeps the constraint, executive decisions, redesigned work, team adoption, and operating evidence in one 90-day engagement.

The engagement does not impose a generic management framework. It begins with the company's real operating truth and stays narrow enough to move. AI may become part of the response, but it must earn its place against simpler changes in leadership, ownership, process, information, and ordinary technology.

Thirteen weeks

From one decision to visible operating change.

Weekly movement keeps the work real. Executive reviews clear decisions and dependencies. Evidence shows whether the change is becoming part of normal operations.

  1. Weeks 1–2

    Lock the constraint

    Confirm the executive sponsor, evidence, measurable finish line, owners, decision rights, dependencies, and boundaries.

  2. Weeks 3–6

    Redesign the work

    Change the workflow, handoffs, meetings, information, roles, and systems required to relieve the constraint.

  3. Weeks 7–10

    Install the change

    Run the new practices with real work, resolve exceptions, enable the team, and keep executive decisions moving.

  4. Weeks 11–13

    Prove and decide

    Review adoption and operating evidence, close gaps, document the new way of working, and decide what should scale next.

Fit matters

Built for leaders ready to change how the company operates.

The strongest fit is a founder-led service, SaaS, or technology-enabled company with roughly 20–150 employees, an executive sponsor, and a constraint important enough to protect for a quarter.

Strong fit

  • One cross-functional constraint matters now
  • Leadership will provide evidence and make decisions
  • A senior sponsor owns the finish line
  • The team can protect weekly working time

Poor fit

  • The buyer wants a generic strategy deck
  • No executive sponsor can make tradeoffs
  • The request is only to install a fashionable tool
  • The company wants guaranteed financial results

Commercial boundaries

One inclusive transformation fee. Exceptional build costs stay explicit.

EC90 starts at $75,000 total. If the Executive Business Diagnostic converts within 30 calendar days, its fee is credited toward that total.

Custom software, substantial data engineering, third-party licenses, travel, and specialist legal or compliance work are separately scoped. Starting prices are introductory minimums and will be reviewed after the first three paid clients.

Start with shared evidence

Is one constraint worth the company’s full attention for one quarter?

If the constraint is already evidence-backed, apply for EC90. If not, begin with the 10-business-day Executive Business Diagnostic.
