Concept draft v0.1 · for open feedbackOmar El Mghari · PMSOX
A product concept for CPA firms, universities and the people who want in

AI took the reps.
We give them back.

The bank recs, accrual tie-outs and invoice ticking that taught every accountant what "wrong" looks like are now done by software. The Accountant Residency is a practice floor where new grads and career changers close simulated books, catch AI's mistakes, and get reviewed by real seniors, so firms can hire people who already have judgment.

Comic: an AI robot says March is reconciled and 100% matched; a junior accountant circles one ledger line in red and replies that line 9 is a prepaid, not an expense. March is reconciled. 100% matched ✓ Not so fast. Line 9 is a prepaid, not an expense. AI ✓ ✓ ✓ ✓ ✓ ✗ ✓ CATCH THE AI · LEVEL 1

01 · The gap

The training work is disappearing

−42%

Professional services internships, 2023 to 2025.

Ⓢ Illinois CPA Society
~75%

Of US accountants are nearing retirement age, with CPA candidates falling.

Ⓢ Randstad salary guide
80%

Of public accountants report difficulty hiring qualified staff.

Ⓢ Zeni accountant survey
1 firm

KPMG is building its own simulator (TaxSIM). Mid-size firms can't.

Ⓢ CFO Brew

Every AI-drafted reconciliation still needs a person who can tell when it is wrong. That instinct used to come from years of doing the work by hand. If firms stop hiring juniors now, around the early 2030s there is no one experienced enough to check the machine.

03 · The flywheel

A machine that feeds itself

The Residency click any step
Step 1 of 6

Cross-side network effects

More residents attract firms. Firm hiring attracts residents. Both attract mentors.

The self-propelling loop ↺

Hired residents return a year or two later as mentors, so mentor supply grows with the user base instead of being recruited.

Data network effect

Every graded attempt and mentor correction shows where people get stuck, which sharpens the next simulation.

04 · Try it

Catch the AI

An AI agent categorized March bank activity for a small e-commerce client. Some of its calls are wrong. Flag the lines you would send back, say why, then check your review. This is the core loop: residents train as reviewers of AI, not replacements for it.

Catch the AI

The AI does the work with planted errors. Find them, explain each one. Trains review judgment.

Mode 2 · speed

Beat the AI

Race the AI on a judgment call (cutoff or accrual?), then compare your reasoning with its reasoning and a mentor's.

Mode 3 · story

The recurring client

One fictional company whose books get messier each month. Fraud cases unlock at higher levels.

Mode 4 · social

Leagues & credential

Cohort leaderboards and a "Certified AI Reviewer" profile firms can verify before an interview.

05 · The economics

Who pays

FirmsSeat subscriptionTrain their own first-years on the floor instead of on client work.
FirmsPlacement feeHire a resident with a verified skills profile.
UniversitiesCourse licensePer-section access, embedded in accounting and AI courses.
ResidentsFree core, paid extrasPractice is free; premium mentor sessions are paid or firm-sponsored.
AI vendorsLicensed review dataConsented, de-identified expert corrections. Later, and only with consent.

First pilot: one 4-week simulated month-end close for a fictional e-commerce client, 10 to 20 residents from a university cohort, 3 to 5 mentors, then one question to two or three firms: would you interview from this list?

06 · What could kill it

Open questions

Cold start

Marketplaces die when no side shows up first. Answer: AI grading makes it useful alone on day one; universities seed residents.

high

"Juniors training the AI that replaced juniors"

The data angle could read as exploitative. Needs explicit consent and a clear value exchange.

high

Does simulated work count?

If platform hours counted toward CPA experience requirements it would be a moat. Requires state-board research.

unknown

Mentor supply

Partners are busy. Retired CPAs and returning alumni may be the real supply.

medium

Big 4 build it themselves

They will, for themselves. The lane is the mid-size firm that cannot.

manageable
