Real CFO leadership, without the full-time hire.
A senior CFO who owns your model, your runway, and your hardest calls. Built on an operator's playbook, delivered by a senior team.
Built for B2B SaaS, AI, and tech-enabled services.
We go deep in a few models instead of dabbling in all of them. If your revenue is recurring, usage-based, or services-led, we already know how your numbers behave.
B2B SaaS
- Vertical & horizontal SaaS
- Developer tools & infrastructure
- Subscription & usage-based models
- PLG and sales-led motions
AI & ML
- AI-native products
- AI-enabled platforms & copilots
- Model & infrastructure companies
- Compute-heavy cost structures
Tech-enabled services
- Professional & managed services
- Agencies & studios
- Marketplaces & platforms
- Hybrid product-plus-services models
Founder-led companies from $2M to $20M+ ARR, venture-backed or bootstrapped, plus earlier-stage teams with at least $2M in funding. If that's you, the seat already speaks your model.
Two ways to put us in the seat.
An ongoing partnership that deepens as you grow, or a single project, done right.
Same senior team either way.
A CFO who owns the numbers, so you can run the company.
- One CFO session a month, and you leave knowing what to do
- A live cash model, so runway is a number, not an argument
- Monthly and quarterly read off your books
- Early warning on the red flags
- Gut-check before a raise, hire, or price change
- Your operating model, budget, and rolling forecast, built and maintained by us
- Budget-vs-actuals every month
- The call on where every dollar goes
- Board-ready reporting and a live dashboard
- Big decisions run through the model first
- Board pack and the narrative behind it, owned
- Clean P&Ls across every product and segment
- Structural problems fixed before a buyer finds them
- Kept exit-ready every week: the model, data room, and diligence-ready numbers maintained
- When a live raise or sale starts, we run it as a separate, time-boxed engagement, scoped to the deal
I've been working with Mariya for only a short period of time and yet the impact she's made will be felt for years. It's bigger than spreadsheets and dollar signs. You won't regret it.
Working numbers in weeks. The payoff compounds in months.
We rebuild your model from actuals in the first month, so you have numbers you can run on fast. The real return builds over the next two to three quarters: cleaner raises, sharper margins, decisions made on time.
One thing, done right.
Fixed scope, fixed price, and a senior CFO on it from day one.
Operating Model Build
An operating model built from your actuals and set to where you're going: revenue, costs, hiring, cash, and the scenarios that decide your next raise or cut. Board-ready, and yours to run from day one.
Financial Diligence
We audit your model, books, systems, unit economics, and margins the way a buyer or investor will, before they ever open a data room. Two working sessions, then a written diligence memo: where you actually stand, what's broken, what to fix first, and the moves that protect your valuation.
Not sure which fits? Start with a call and we'll point you to the right one, even if it's none of them.
We came to FounderFirst for a financial review and they far exceeded our expectations. It didn't just show where we were going wrong, it gave us a clear roadmap to fix it. I'd recommend them to any founder.
Strategic finance leadership. Not back office.
Whichever way you work with us, the boundary is the same. We own the decisions above your books, not the mechanics inside them.
The seat above your books.

The business itself.

Compliance & back office.

We work alongside the providers you already have, and refer you to ones we trust if you don't have them yet. One seat, clear boundaries, no overlap.
From first call to a CFO in the seat.
No six-week discovery, no junior handoff. Every engagement is led by a senior CFO and backed by an FP&A team.
Find out where you are. Get where you need to be.
A short application, then a call, and we'll tell you the right starting point. No deck. No pitch. Just an honest read on where finance sits in your business today.
