Engagement Models
Each model is staffed personally by a named partner from the firm’s 18-person senior bench. No associate pools, no offshore handoffs, no model re-invented from a slide library.
01
A senior partner sits inside your weekly operating cadence as your de facto VP of Finance — for as long as you need one and not a day longer.
You get the closing cadence, the investor narrative, and the board-readiness of a $400K full-time hire, paid on a fractional envelope. The partner builds (or rebuilds) your finance function alongside you, then transitions cleanly when you’re ready to hire in-house.
How fractional CFO works →02
A fixed-scope engagement with a single, named deliverable: a fundable financial package, on a deadline that maps to your round.
Built for founders with a date circled on the calendar. We rebuild your model against institutional-grade assumptions, pressure-test unit economics, and hand you a data room a lead investor can diligence without follow-up. The same Capital Readiness Scorecard used by 600+ founders is applied to your numbers.
Take the Scorecard →03
A partner joins the deal as your financial translator between founders, investors, and counsel — from first IC meeting to wire.
We do not provide attest-level assurance. We do something more useful for founders: we sit across the table from your lead, anticipate the diligence questions before they are asked, and keep the round from drifting on a missing schedule. Trusted advisor to 2 of the top 25 Y Combinator alumni companies and 11 Inc. 5000 honorees.

Six hundred and twelve founders have used the Scorecard to benchmark their investor readiness before a fundraise, a board meeting, or a finance hire. The instrument is proprietary to Walsh & Partners and is calibrated against our 312-engagement history and the 140+ rounds we have supported since 2017.
You receive a private score across five axes — capital narrative, unit economics, governance, runway posture, and narrative hygiene — alongside the median score of comparable Series A–C SaaS and tech-enabled companies in our dataset. There is no sales call attached. The diagnostic exists so that when you do book a strategy call, the first ten minutes are signal, not intake.
The Scorecard and the Walsh Capital Readiness Index have been cited by TechCrunch (March 2024) and CFO Dive (June 2024).
