A quiet, sunlit office interior

Home / About

A CFO who sees the road ahead, not just the rearview.

You run a founder-led company that is growing faster than your view of the numbers. Rainier puts a senior CFO in your corner, part-time, to give you runway you can see to the week and a clear answer to every "what happens if" before it costs you.

The gap your books leave open

Your reports tell you where the cash has been. Not where it is headed.

Clean books are a record of the past. They go quiet at the exact moment you need them most: the hire you are about to make, the price you are about to set, the raise you are about to start. Rainier turns that record into a forward view you can steer by, so the next big call is a decision instead of a guess.

In practice you get a rolling forecast you trust, a runway number you can quote on the spot, and the one or two moves that change the next two quarters. Your bookkeeper, controller, and CPA keep doing what they do. They keep the record straight. Rainier helps you decide what to do about it.

Where the work happens. The decision in front of you, not the report behind you.

One name on the account. The one you talk to.
No queue, no handoff

You work with the senior CFO directly. Every time.

Rainier is deliberately small, so the person who builds your forecast is the person who sits in your board prep and picks up the phone when a decision will not wait. No junior analyst reading from a script, no account manager between you and the answer. The fastest way to know if it fits is a short conversation.

What you can count on

A few promises, no fine print.

The same standard whether you are raising next quarter or just want to stop sweating payroll week.

  • You see the work, not buzzwords.You get walked through the forecast line by line, so you can defend every number yourself. No "trusted advisor" language standing in for an answer.
  • One senior CFO owns the outcome.The same experienced person stays close to your business and answers for the call. Not a portal, not a queue, not a junior reading from a script.
  • You leave every conversation clear on the next move.The model gets translated into the one or two decisions in front of you. If you cannot follow the reasoning, the job is not done.
  • A flat number before you commit.Every engagement is scoped with a clear price up front. No hourly meter, no surprise invoices. And if this is not the right fit for you, you will hear that first.
