Alignment · Clarity · Execution

The decisions all come to you.
The numbers rarely do.

Running a company means carrying it: payroll on the fifteenth, the lease, the hire you keep putting off, the season that starts whether you are ready or not. We exist so that fewer of those decisions are made alone, and none without a clear view of the money.

Our story

Where
we began.

Ellory Prism grew out of years inside enterprise finance: planning cycles, forecasts due by Monday, budget lines that became decisions about people. What we kept is a discipline, not a spreadsheet: assumptions written down, ranges instead of promises, the same figures read the same way by everyone who decides.

Then the tools changed, and most businesses were sold them as magic. We put the discipline underneath instead.

A well-run company is not louder. It is calmer: a clear view of the money, systems that do the repetitive work quietly, and people who trust both because they understand them. That is what we build, in that order.

“Most businesses were offered a chatbot. Very few were offered a number.”Why we build the way we do
Sonoma and Marin

Rooted in Sonoma and Marin, working anywhere in the United States.

Ellory Prism is based in Cotati, in Sonoma County. Across Sonoma and Marin we are glad to sit at your table, in person, as often as the work calls for it.

Anywhere else in the United States, we work the same way remotely: the same standard, the same care, and someone to call.

Three practices · one discipline

Finance. Systems.
Studio.

Finance reads the numbers, Systems builds on them, and Studio trains your people. Enter through any one; the firm will know where to take you next.

I.

Finance

Clarity

What the numbers mean for the next decision: cash, margin, pricing, and a plan you will actually read.

  • A thirteen-week cash view, assumptions written down
  • Margin by customer and by product
  • Pricing, budgets, plan against actual
  • Decision support for hires, leases and raises

II.

Systems

Execution

Custom intelligent systems for any part of the business, each scoped as a financial decision and delivered with its team trained.

  • Internal tools and sites for your people
  • Assistants on your own documents
  • Workflow, reporting and inventory automation
  • A business case before, a check at day thirty
The Systems practice
III.

Studio

Alignment

Training that starts with what changes in your numbers, then the tools, then the judgment to use them well.

  • The leadership workshop
  • Team programs, by role
  • An AI use policy and a playbook you keep
  • Included with every system we build
The Studio
Finance finds it. Systems builds it. Studio makes it stay.

Prism Brain.

01
A business case before a build.

Cost, expected return, payback, and how we will measure it. On one page, before anything exists.

02
Training with everything.

Every system arrives with its team trained, or it has not been delivered.

03
A human yes.

Nothing we build moves money, signs, or files without a person approving it first.

04
Honest about the future.

Designed by Ellory Prism, built with AI assistance, checked against real results. Forecasts are ranges, never promises.
