Consumer agents that read life events and recommend products. Wealth Plan in front of the largest customer base in American banking. Every agent converges on one question — what should this household actually do? — and today every answer in the industry is an estimate. MaxiFi is the deterministic engine that computes it: provably, reproducibly, guaranteeably.
The growth case →Request the briefingJPMorgan is shipping agentic AI faster than any bank: agents that work for hours without human input, consumer agents that read life events and recommend products, Wealth Plan and Personal Advisors carrying the affluent push. The ambition is right. The layer under it — the number the agent speaks when a household asks what to do — is, today, a model estimate. At 91 million customers, the gap between an estimated answer and a computed one is the biggest single number in consumer finance.
Bank of America says personalized insights. Wells says smart guidance. None — and no AI lab — can substantiate the claim that matters. MaxiFi can: a deterministic engine that solves the lifetime plan for a household's facts and assumptions — every dollar of taxes and Social Security computed under current law, same inputs, same answer, every time, with an audit trail.
That changes what the claim is. Backed by the pedigree — thirty years of Laurence Kotlikoff's economics, taught with at MIT Sloan by Nobel laureate Robert Merton — and by the reproducible computations themselves, the accuracy claim stops being puffery and becomes a substantiated statement of fact. And determinism unlocks what a claim alone never could: a bounded Accuracy Guarantee with a defined remedy — the play that built TurboTax's franchise, never before available in planning, insurable only because the math is exact.
The substantiation regime that polices financial advertising — FINRA 2210's fair-and-not-misleading standard, FTC substantiation doctrine — protects this claim. Rivals can run vague accuracy language; what they cannot run is your claim: the specific, falsifiable, guaranteed one. Copying it without the engine is a false claim regulators, NAD panels, and Lanham Act suits will punish.
“The only bank whose money answers are provably computed — and guaranteed” — advertising with a substantiation file behind it, across 91M customers.
From goals coach to computed answer — the conversion wedge from banking to Personal Advisors to full advisory.
The household whose plan lives at Chase — computed, guaranteed, re-run on every law change — does not move its money.
Your agents handle the conversation; MaxiFi handles the computation. Recommendations become auditable outputs, not model guesses.
| BofA / Merrill | Wells / Citi | JPMorgan + MaxiFi | |
|---|---|---|---|
| The advice claim | “Personalized insights” | “Smart guidance” | “Provably computed — and guaranteed” |
| Behind the claim | Heuristics + Monte Carlo | Heuristics | Deterministic optimization, audit trail |
| Can rivals copy it? | The words, not the proof | The words, not the proof | Imitation = a false claim, policed by regulators |
One quarter of the claim in the consumer funnel — Wealth Plan upgrades, the affluent campaign, the guarantee — answers what no forecast can. Owning MaxiFi is the exclusive right to run that play, and to deny it to Bank of America, Wells, Citi, and Morgan Stanley permanently. It is a revenue line, not a legal reserve.
MaxiFi (Economic Security Planning, Inc.) uses consumption smoothing and dynamic programming to compute the single, mathematically optimal lifetime plan — solving simultaneously across Social Security strategy, federal and state taxes, Roth-conversion sequencing, withdrawal order, insurance sizing, and upside investing. For a household's facts and assumptions it solves — not guesses: same inputs, same answer, every time, with an audit trail.
Prof. Laurence Kotlikoff — William Fairfield Warren Professor at Boston University; Harvard Ph.D.; former Senior Economist, President's Council of Economic Advisers; named by The Economist among the 25 most influential economists.
Taught with at MIT Sloan by Nobel laureate Robert Merton as an “outstanding science-based lifecycle and retirement management platform” (Merton does not endorse products); featured in Bankrate's “Best financial planning software of 2025” roundup. The economics trace to Nobel-recognized lifecycle work.
Patented algorithms and thirty years of continuously maintained federal/state tax, Social Security, and benefit rules with a validation record — exactly the IP a language model cannot reverse-engineer and a build team cannot shortcut.
Larry Kotlikoff intends to stay on with the acquirer — to integrate the engine, validate the training and guarantee programs, and continue as spokesperson. The acquirer buys the engine and keeps the economist who built it.
MaxiFi computes each household's lifetime plan from the data Chase already holds; bankers and advisors review and own the relationship; the agents call the engine instead of guessing. The WealthOS / 55ip / Nutmeg playbook: buy the capability, deploy it across the franchise. Deterministic, auditable outputs — OCC- and CFPB-legible by construction — and the conversation stays JPMorgan's.
Courts and regulators are converging on AI-answer accountability — the first FINRA exam cycle to treat generative AI as a standalone topic reaches the reliability and accuracy of the AI model and embedded third-party tools, and banking supervisors will ask the same question of consumer agents. MaxiFi converts the scaled money answer from a liability into an exhibit: computed, verifiable, reproducible.
And the engine ships with the architecture that keeps the floor solid under an advertised claim: assumptions and law-table version disclosed on every output, customer input attestation, versioned rule tables with re-run notices on law changes, and the Accuracy Guarantee's defined remedy. The audit trail proves each customer was told exactly what was — and wasn't — promised.
We price the asset on the growth case above. The defense beneath it is a term of the deal, not the deal — and, like the claim itself, it is denied to every competitor the day it is yours.
A frontier model's retirement “smile” ran 13% too low in each of a real household's 40 remaining years against MaxiFi's computed path — dated, dollar-specific, reproducible.
Four frontier AIs sized the same father's coverage at $1.3M, $1.4M, and $3.8M — against MaxiFi's internally consistent $2.09M. Every shortcut the AIs used is programmable — and wrong.
One retirement question, three frontier engines, three different verdicts — with MIT's Andrew Lo noting these tools carry no best-interest duty. The category estimates; the divergence is the proof.
The tests publish to 145,000+ subscribers and counting — credibility no rival in the category can match, and it conveys with the acquisition.
Larry spent thirty years building what private banks compute for eight-figure clients — for everyone else. We are running a deliberately narrow process to place it where it answers the most real households, and nobody banks more of them than Chase.
The next step: a 30-minute briefing — MaxiFi solves a real household's lifetime plan, live, while a frontier model is asked to match it. The gap is the thesis; the funnel is the price.
