Hire your AI CFO

Cash flow, pricing, and models — run by a finance partner, not a spreadsheet.

Updated 2026-04-17

This is a role guide, not an installed employee. It explains what the role owns and how Tycoon runs it. Nothing is hired or activated until you choose it.

What your AI CFO does

01Maintain a live cash flow model with runway projections updated daily
02Run the monthly close — revenue, COGS, burn, MRR, ARR, net dollar retention
03Own pricing: run experiments, measure LTV impact, propose changes with math behind them
04Produce investor-grade monthly updates with commentary that tells the story behind the numbers
05Flag expense anomalies and revenue concentration risks before they become problems
06Answer 'what if' scenarios instantly: what if we raise prices 20%? what if churn drops 1 point?
07Coordinate with the COO on vendor spend and the CEO on strategic resource allocation
08Keep the tax calendar, founder compensation, and equity cap table clean and current

Workflows on autopilot

Daily cash flow heartbeat

Pulls bank and Stripe balances each morning. Updates the runway model. Flags anomalies (unusual refunds, chargebacks, vendor overcharges).

Monthly close

Runs the full close by the 5th: revenue recognition, expense categorization, MRR movements, net dollar retention. Drafts the investor update.

Pricing experiment loop

Quarterly: proposes one pricing test with LTV modeling, runs it, measures over 60 days, commits or reverts with written rationale.

Scenario modeling on demand

When the founder asks 'what if we hire X?' or 'what if churn goes up 1%?', returns a full model delta in minutes, not days.

Expense anomaly alerts

Real-time flags: any expense outside normal range, duplicate charges, vendor-bill spikes, FX fluctuations. Escalates only material items.

Runway checkpoint

When runway drops below 9 months (or founder-set threshold), triggers a mandatory review with CEO and COO to decide: cut, price, raise.

Without vs With a AI CFO

Without

  • You open Stripe at the end of each month and try to reconstruct the story
  • Pricing decisions made by gut and founder conversation at a coffee shop
  • You discover on day 87 that runway is actually 6 months, not 12
  • Investor updates are painful 3-hour drafts the night before
  • A $15K/month fractional CFO who reviews your books once a month

With Tycoon

  • The CFO runs a monthly close by the 5th with commentary
  • Pricing changes backed by LTV math and 60-day measurement cycles
  • The daily heartbeat means you know runway to the week at all times
  • The CFO drafts a solid update every month — you edit for voice, not numbers
  • An AI CFO that runs the books daily for under $300/month

A day in the life of your AI CFO

06:45Pulls overnight Stripe, bank, and payroll activity. Updates cash flow; flags a refund spike on one product tier.
09:00Runs the daily MRR delta report. Two new annual deals; one churn. Drafts the net ARR commentary.
10:30Answers the CEO's question on what a 10% price raise does to projected runway. Returns a full scenario inside 4 minutes.
13:00Reviews the CMO's launch budget proposal. Approves with a $2K cap adjustment tied to CAC payback threshold.
15:00Completes the monthly investor update draft. Posts to the CEO for review with a summary of what changed vs last month.
17:30Flags sales-tax threshold crossed in Texas; triggers the Anrok workflow and calendars a 90-day filing reminder.
22:00Heartbeat: confirms bank balances reconciled, Stripe webhook gaps zero, tomorrow's payroll clean.

FAQ

Frequently asked questions

Clear answers about wallet credit, usage, subscriptions, and how Tycoon charges for work.

Can an AI CFO actually close books and do real accounting?

Yes, with the same boundaries a fractional human CFO has. The AI CFO runs the monthly close, revenue recognition, MRR/ARR math, and expense categorization — but still hands off to an accountant or to Pilot/Bench for the formal GAAP books if you need audit-ready statements. For most one-person companies pre-$5M revenue, the AI CFO's close is the books. For regulated or audit-track companies, you pair the AI CFO with a human firm for sign-off, and the AI does 90% of the prep work. Either way you stop opening spreadsheets at the end of each month.

How accurate is the AI CFO's modeling?

As accurate as the data sources allow. The CFO reads Stripe, your bank feed, your payroll, and your vendor feeds directly — no manual entry, no stale snapshots. Models are built and validated against historical data on day one. Scenario answers are deterministic math on top of those feeds, not guesses. Where accuracy falls off is in forward assumptions (churn projection, ad efficiency) — those are always assumptions, whether a human or AI sets them. The CFO shows its work so you can challenge the assumption, not the arithmetic. Medvi-scale founders have used this same pattern to track $400M+ revenue operations without an in-house finance team.

Does the AI CFO handle sales tax, VAT, and international compliance?

It handles the monitoring and the workflows; it doesn't replace a tax firm for filings. The AI CFO watches your threshold status in every US state, every EU country, and key international markets, integrates with Stripe Tax / Anrok / Numeral for collection, and triggers filing workflows as thresholds are crossed. It maintains the calendar of registration deadlines and nexus review. For actual filing you're still using the compliance vendor. For the planning, monitoring, and 90% of the operational overhead, the AI CFO removes it from your plate. This is the class of work most solo founders accidentally drop until a state sends a notice.

What happens to my fractional CFO if I hire an AI CFO?

Most founders running Tycoon who already have a fractional CFO drop the retainer and shift to project-based engagements — raise prep, audit support, specific 1099 projects. You save most of the retainer while still having expert human review for the moments that need it. Founders who don't have a fractional CFO yet typically skip hiring one entirely and bring in a human only for financing events. For a pre-Series-A one-person company, the AI CFO plus an accountant for taxes is often the entire finance function.

What does the AI CFO cost vs a real CFO hire?

A full-time VP of Finance or CFO in the US costs $200K-$400K plus benefits and equity. A fractional CFO runs $5K-$15K/month. The AI CFO inside Tycoon typically costs $50-$300/month in usage, depending on report volume and modeling frequency. That's an order-of-magnitude reduction versus a fractional hire, and close to two orders of magnitude versus a full-time one. The tradeoff is that you still want a human accountant for formal filings. Total finance-function cost for a one-person company running Tycoon: typically $250-$800/month all in, versus $8K-$30K+ for the equivalent human team.
