A model is a machine for answering “what if” — most are sculptures
Most financial models are built once, for one meeting, by someone who never has to reconcile them to reality. They look impressive, hardcode their conclusions, and fall apart the first time an investor asks “what happens if sales slip a quarter?”
A working model is different: driver-based, assumption-documented, scenario-ready, and tied to the same account structure as your books — so it keeps telling the truth after the meeting ends.
What we do
Driver-based operating models. Headcount plans with fully loaded costs, revenue built contract-by-contract or cohort-by-cohort, vendor-level expense run-rates — a model that answers “what if” in minutes.
Fundraising models. The financial core of your raise: growth scenarios, unit economics, use of funds, runway under each outcome — structured to survive diligence, because it was built by people who reconcile ledgers for a living.
DCF valuation and scenario analysis. Defensible valuations with explicit assumptions and sensitivity tables — not a single magic number.
GL-connected forecasting. For ongoing clients, the model plugs into your actuals monthly, becoming a rolling forecast rather than a one-time artifact.
What you get
A financial instrument you can steer with: every big decision priced before you make it, every investor question answerable live, every assumption visible and changeable.
A Living Company Budget — Rolling, GL-Connected, and Reconciled Every Month
Runway, hiring costs, and raise timing turned from guesses into a schedule.

What makes a financial model 'driver-based'?
Every number traces to an operational driver — headcount, contracts, pricing, conversion rates, vendor run-rates — instead of being typed in. Change the driver and the whole model updates. That's what makes a model a decision tool instead of a spreadsheet sculpture.
Will the model survive investor due diligence?
That's the design goal: clean structure, documented assumptions, no hardcoded mysteries, scenarios that flex sensibly. Models built by accountants reconcile to actuals — which is precisely what diligence teams check first.
Do you do valuations?
Yes — DCF valuation with scenario and sensitivity analysis, for fundraising, buy/sell decisions, and partner buyouts.
Can the model stay connected to our actual results?
Yes — our preferred setup wires the model to your chart of accounts and reconciles it to the general ledger monthly, so forecast-vs-actual is a living view, not an annual autopsy.
