Whetstone

Do the work only a fractional CFO can do. Hand off the rest.

Let AI handle the busywork. Only do the work that matters.

Too much of your week is consumed by work that doesn't need your judgment.

Chasing down data from three different systems, reconciling bank feeds, building board decks, formatting cash flow projections — real work, just not your work.

But you don't have to do it alone.

You are the strategic advisor.
AI is your tireless finance manager.

Tireless, encyclopedic, and fast — but it doesn't know your clients' business models or your strategic insight. You guide it with your expertise.

Direct it. Review it. Sign off.

  • Assign the first pass. Data consolidation, variance calculations, board deck formatting, KPI dashboards — the work that needs elbow grease, not strategic insight.
  • Review, don't draft. Let AI produce the first version of monthly reporting, cash flow projections, scenario models. You apply judgment, refine the narrative, sign off.
  • Build institutional knowledge. Teach AI each client's chart of accounts, reporting cadence, and board priorities. It becomes your institutional memory across five clients.

For fractional CFOs whose time is the bottleneck.

Multi-client portfolio management

Switching context between five clients daily. AI maintains continuity.

Board reporting and decks

Narrative summaries and visual formatting consuming strategic prep time.

Cash flow projections and scenarios

Building the model before you can advise on the decision.

Systems scattered across clients

QuickBooks, NetSuite, spreadsheets, bank portals — normalizing it all manually.

Monthly close and variance analysis

Reconciliation and commentary before the actual strategic conversation.

Fundraising support

Data rooms, financial narratives, and investor materials displacing advisory time.

Your time is the constraint. Your judgment is the value.
