Know your numbers cold.
You built the company. You should not have to guess at the numbers. Sit a seasoned CFO next to you, part-time, and answer runway, margin, and the next big decision before anyone asks.
You do not need another report to scroll past. You need someone who tells you which lever to pull, then stays in it with you until the cash shows up.
Your bookkeeper records the past. Your controller keeps it accurate. A CFO decides the future. Rainier works at that layer, alongside the team you already pay, so the next call you make on cash, pricing, or hiring is one you can defend.
Three answers you stop guessing at.
How long is the runway
See cash to the week, and know what buys you more of it.
Which moves actually pay
Price, hire, and spend off real margins and unit economics, not a hunch.
Will the raise hold up
Walk into the round or the sale with a model that survives the hard questions.
See the cash crunch before it arrives.
The tight month is rarely a surprise to the numbers. It is a surprise to you. A rolling cash flow forecast, built with you in the first weeks and kept current, shows the squeeze coming while you still have moves: a delayed hire, a collections push, a different terms ask. You decide early, not at the wire.
Diagnose first, then decide.
No bloated onboarding, no fixed template. You start with a conversation and we build from what your business actually needs.
A free conversation
Tell the CFO where it hurts: the runway question, the board deck, the margin you cannot pin down. Free, no obligation.
Find what needs attention
Get inside your cash, your close, and your margins, and name the one or two things to fix first instead of all of it at once.
A CFO in your corner
A live forecast, board-ready reporting, and a standing call where the hard numbers get decided. Part-time, scaled to your stage.
Your model has its own math. Start with someone who knows it.

Small and new, on purpose.
Rainier is a deliberately small practice: one senior CFO, working with a short list of founders, part-time. No junior analyst learning on your books. No account manager between you and the person doing the thinking. The principal reads your numbers and the principal makes the calls with you. New means hungry, and it means your business gets real attention, not the leftovers of a packed firm.
Whether this is right for you.
- You run the company, you are growing, and a raise or a sale is on the horizon.
- Your books are roughly clean and what you are missing is the decision layer above them.
- You want someone who acts on the numbers with you, not a monthly PDF you skim and file.
- You are very early and pre-revenue. A great bookkeeper comes first, and we will say so on the call.
- You want someone to record the past, not help you decide the future.
- You are shopping for the cheapest hour rather than the best decision.
