What we do

Four ways in, each its own engagement.

Most firms sell you a package. We don't. Bring us in for a single problem, or layer several into a full finance function. Pick where it hurts; each one stands alone.

Why companies call us

Finance gets harder, quietly, as you grow.

Revenue climbs, the team scales, and the finance function that worked at $2M starts cracking. The symptoms look different depending on what you need, but they all cost you time, clarity, and confidence in the numbers.

01

The close drags into week two

Month-end takes too long and you still don't fully trust what comes out. Decisions wait on numbers that aren't ready.

02

The board wants a forecast you can defend

You have a budget from January nobody believes anymore, not a living model you can run scenarios against.

03

You need a CFO's judgment, not a CFO's salary

Cash, capital, fundraising, unit economics: real decisions that need senior finance experience well before a full-time hire makes sense.

04

Your numbers live in spreadsheets that break

Reporting is manual, version control is a guess, and pulling a board deck together eats days every month.

How we work

We start with the problem, not the tool.

Whether it's a single forecast or a full finance build, the order is the same: understand the work before touching the system. It's why our engagements land instead of stalling.

Step 01

Diagnose

We map your close, data sources, and reporting, then pinpoint exactly where time and clarity are leaking today.

Step 02

Scope

We right-size the engagement to what you actually need now: one service or several, not a one-size package.

Step 03

Build

Clean books, a real forecast model, controls, or a configured platform, built around your workflow, not a template.

Step 04

Run or hand off

Stay hands-on with ongoing fractional support, or we train your team and hand over the keys. Your call. We don't engineer dependency.

Retainer-based, by design. Engagements run on a fixed monthly retainer scoped to the work: predictable cost, senior attention, and the room to scale up or down as your needs change. No hourly meters, no surprise invoices.

The math

Fractional vs. a full-time hire.

Senior finance talent is expensive, slow to hire, and hard to keep. Fractional gets you the same expertise, sized to exactly what you need, and only what you need.

Senior CFO / FP&A / accounting on demand
No benefits, taxes, or recruiting overhead
Scale services up or down as you grow
One accountable partner, no key-person risk
Tools we work in

We meet your stack where it is.

We're fluent across the systems growing finance teams actually run on, so we plug into what you already use instead of forcing a migration. And where a platform genuinely helps, we implement the right one.
