Financial modeling
Financial modeling for startups, built for decisions.
A startup financial model should help you decide what to do next, not become another spreadsheet no one trusts. We connect revenue, headcount, cash, burn, and runway to the choices in front of you, built from books our team keeps current.
What your startup financial model should answer
The financial questions that matter before you make a commitment.
Operating model
A connected revenue, headcount, expense, cash, and runway model built around the way your business actually operates.
Hiring plan
See what each planned hire does to burn, cash, and the milestones you need to reach before the next round.
Fundraise scenarios
Model the amount to raise, the timing, and the downside case before you start investor conversations.
Runway planning
Compare the decisions in front of you: hire, slow spend, change pricing, or raise, before they become irreversible.
Board-ready reporting
Turn the model into a clear forecast and a board conversation grounded in the same financials your team closes monthly.
Revenue model support
Model subscriptions, usage, services, or a mix of revenue streams with assumptions your finance team can maintain.
Financial planning starts with a trustworthy baseline
A model cannot rescue unreliable inputs. We begin with current books, then make the operating assumptions explicit: how revenue is expected to develop, when people will be hired, what spend changes with growth, and what each scenario means for cash. The result is a model you can explain to a board or investor, and keep using after the fundraising process ends.
For pre-PMF companies, financial modeling is available through fractional CFO support alongside fundraising and financial planning. It is included in the Post PMF plan. For the day-to-day numbers behind your forecast, see our startup accounting services. For the immediate cash view, use the free 13-week cash flow forecast or startup runway calculator.
Financial modeling FAQ
Straight answers on scope, timing, and how this fits with your books.
What is financial modeling for startups?
Financial modeling for startups turns operating assumptions into a connected forecast. It typically covers revenue, headcount, operating expenses, cash, burn, and runway so a founder can see the financial effect of a hiring plan, pricing decision, or fundraise before committing.
When should a startup build a financial model?
Build or refresh a model before a fundraise, board meeting, hiring ramp, major pricing change, or any decision that materially changes burn or runway. Early teams do not need a complicated model for its own sake, but they do need one that answers the decisions in front of them.
What should a startup financial model include?
A useful startup financial model connects revenue assumptions, headcount, operating expenses, cash, burn, and runway. The right detail depends on the company, but it should make the key assumptions visible and let you test changes without rebuilding the forecast from scratch.
Can AG Accounting build a model from our existing books?
Yes. Our fractional CFO work starts from books our team keeps current and reconciled. That makes the model more useful because it uses an agreed financial baseline rather than a disconnected spreadsheet.
Is financial modeling included in your accounting plans?
Pre-PMF companies can add fractional CFO support for financial planning and modeling. Financial modeling is included with the Post PMF plan. The right cadence depends on your stage and the decisions ahead.
