the sigma method
The operational rigor of private equity,
built for businesses your size.
When a private equity firm buys a company, it does not just give advice. It sends
operators in to fix the books, rebuild the systems, sharpen the marketing and
restructure how the business grows. That is standard practice — for companies
already worth millions. Sigma runs the same playbook for small businesses and
startups - with you staying in control.
Advice is cheap. Building is the hard part.
A consultant leaves you a document. Six months later the document is in a drawer and nothing has changed, because the owner who was already out of hours was handed more work.
We do the work instead. We set up the bookkeeping and run it. We build the website and maintain it. We write the processes and train the team on them. When the plan calls for a hire, a price increase or a new revenue line, we are in the room for it.
That is the difference between a consultant and an operational architect: we are measured by what the business looks like a year later, not by the quality of the slide deck.
Who this is for
Small business owners and startup founders. The plumber scaling past one truck. The founder still running everything from her phone. The shop that is profitable but chaotic and cannot tell you which jobs actually make money.
Not multi-million-dollar conglomerates. Firms that do this work professionally consider businesses your size too small to take the call. We built Sigma for exactly those businesses, because that is where this discipline changes the most.
the four pillars
Where revenue actually comes from
Growth is never one lever. These four areas are connected, and a weakness in one shows up as a
symptom in another. We review all four in every engagement.
01
Financial
Clean books, real margins, cash you can see coming. The same financial clarity an investor would demand before writing a check.
02
Digital
Website, search presence, and the way customers find and judge you. Built to bring in work, not to win design awards.
03
Operational
Systems, documented processes, and the daily rhythm of the work - Lean Six Sigma discipline - scaled down to fit a small team.
04
Strategic & Capital
How the company is structured to grow: pricing, capacity, ownership, and the kind of deal thinking usually reserved for much larger businesses.
how we get paid
Fee, equity, or both
The structure follows the work. The more build we take on, the more willing we are to tie our
pay to the result.
Fee
A straightforward monthly engagement. You pay for the work, you keep every bit of the business. This is how most clients start and how most stay.
Fee plus upside
A reduced monthly fee paired with a share of the growth we help create. Suited to owners who want more hands on deck than a flat fee comfortably buys.
Equity or Profit Share
We take a stake instead of most of the fee and get paid when the business gets more valuable. Deep involvement, long horizon, selective by design.
Every engagement — whatever the structure — starts the same way: the discovery session and a written
plan you own.
Common questions
What is an operational architect?
Someone who works inside your business instead of just advising it. Consultants hand you a report. Investors buy control. We do the actual work — books, systems, website, growth structure — and take payment as a fee, a share of the upside, or both.
How does an equity or profit-share engagement work?
We reduce or defer the monthly fee in exchange for a share of profit or ownership, agreed in writing up front. It only makes sense when the business has room to grow and the owner wants us deeply involved for a long stretch, so it is selective.
Do I have to give up equity to work with you?
No. Most clients pay a straightforward fee and keep one hundred percent of the business. Equity is one option among several, never a requirement.
Are we too small for this?
If you are a small business or a startup, you are exactly the size we are built for. The firms that do this kind of work usually start at companies worth millions. We start where the help actually matters.
