Modeling & Forecasting
Driver-based models that survive diligence and tell you the truth about the next eighteen months.
Fractional CFO · Seed to Series C
Financial command for companies in the fight.
Fifth Legion gives venture-backed founders a senior finance partner — modeling, fundraising, and board strategy — without the cost or wait of a full-time hire.
What we help you build
Finance that's ready before the moment that needs it.
Fundraising
Raise-ready finance
A model and data room built to hold up in diligence — and a partner to run the financial side of your round.
Reporting
Board-ready every month
Board decks and investor updates that keep your cap table aligned and your narrative sharp between rounds.
Operating
Built for venture pace
Forecasts, hiring plans, and a close process tuned to the scrutiny of a seed-to-Series-C startup.
Solutions
A full finance function, on a fractional footing.
Fundraising & Cap Table
Round strategy, ESOP allocation, dilution scenarios, and a data room your lead investor actually trusts.
Board & Investor Comms
Decks, narratives, and updates that build conviction in the quarters between rounds.
FP&A & Finance Ops
Budgets, hiring plans, and the close process to run them without month-end surprises.
How we work
Assess. Install. Operate. Raise.
One senior partner, embedded with your team — not a junior analyst and a software seat.
01
Assess
A two-week audit and model rebuild. We learn the business and find what's quietly breaking.
02
Install
Reporting cadence, budget, and the handful of KPIs your team will actually use.
03
Operate
Monthly close, rolling forecasts, and board prep on a steady, unremarkable rhythm.
04
Raise
When it's time, we run the financial side of the round end to end — model to close.
“Allocating our employee option pool meant getting every grant fair to the team and airtight against our contractual obligations. Fifth Legion built a sophisticated model to simulate the scenarios, and landed us on an allocation our people earned and trusted — with not a single covenant out of place.”
Bring in your CFO before you need one.
A 45-minute working session, no pitch. We'll pressure-test your model and tell you where the next round breaks.
