Executive Advisory Systems (EAS) is the practice of designing, building, and operating the systems through which a small executive team runs a complex company, and then transferring those systems to the client's own people.

It rests on four pillars: executive advisory systems architecture, executive operating systems, GTM engineering, and financial expert systems. The unit of work is an operating capability rather than a report or a software deployment. It is built for companies with $10M–$70M in revenue, whose C-suite of three to six people each covers two or three functional jobs.

An Executive Operating System is the cadence, playbooks, instrumentation, and rituals through which a leadership team actually runs the company.

It covers the weekly, monthly, and quarterly operating rhythm, the KPI tree connecting board-level outcomes to department-level drivers, decision rights and escalation paths, and the standard agendas where numbers are confronted and commitments made. Most companies at this size have a calendar full of meetings and no operating system.

Governed AI is artificial intelligence deployed with explicit decision classes, human review gates, audit trails, and model performance reviewed on a regular cadence.

Decisions are classified as automate, recommend, review, or human-only, and the review gates are designed to be real: thresholds, sampling, four-eyes checks, and logged reasoning. The goal is encoded expertise with explainable outputs, not a black box that emits numbers nobody can defend to a board or a lender.

Human-in-the-loop (HITL) means a named, accountable person sits between an AI system's output and the consequence of acting on it.

AI compresses the distance between a question and a decision-grade answer; it never replaces the senior human accountable for that answer. In practice this is a set of designed gates: approval thresholds, sampling rates, and escalation paths, reviewed inside the monthly operating cadence like any other operational control.

GTM engineering is go-to-market treated as an engineered, instrumented system rather than a collection of departments and campaigns.

It covers ICP definition, segment and territory design, funnel math with stage-exit criteria, signal capture and attribution honest enough to survive a CFO's scrutiny, pricing governance, and the win/loss loop that makes the system self-correcting. Marketing, sales, and customer success run as one instrumented pipeline with one version of the truth.

Financial expert systems are governed, auditable systems combining AI, rules, and human review that encode CFO-grade financial logic with explainable outputs.

They cover driver-based forecasting, close acceleration, cash and runway instrumentation, unit economics, pricing analytics, and scenario engines for the shocks mid-market companies absorb without hedging infrastructure. The term is chosen deliberately: the goal is encoded expertise with review gates, not an opaque model.

A governed data layer is one reconciled version of the truth across accounting, CRM, and operational systems, with data contracts, lineage, and access controls.

It is built first and treated as non-negotiable, because an expert system running on unreconciled data is a faster way to be confidently wrong. Automating five offices separately on five versions of the truth simply recreates the silo problem in AI form.

Judgment leverage is the consulting model in which senior operators wield governed AI so that one expert delivers what previously took a team.

It contrasts with headcount leverage, where partners sell and pyramids of junior generalists deliver, and with technology leverage, where forward-deployed engineers ship model-deep workflows. Judgment leverage is what makes senior-only delivery economically viable for a $10M–$70M P&L.

A fractional CFO is an experienced finance executive who works with a company part-time, providing the strategic financial leadership of a full-time CFO without the full-time cost.

A full-time CFO at a $10M–$70M company typically costs $300,000 to $500,000 a year in total compensation. A fractional engagement is priced against a defined scope and cadence, and at F3 Insights it goes further than advice: the fractional CFO embeds in the operating cadence and builds the systems the team keeps.

A thirteen-week cash flow forecast is a rolling weekly view of cash in and cash out over the next thirteen weeks, maintained weekly rather than rebuilt quarterly.

It is the CFO's core liquidity instrument because it shows the timing of a cash problem while there is still time to act on it. Growth consumes cash, and a bank balance is a lagging indicator; a rolling weekly view turns liquidity from something discovered into something managed.
