The “leaders” who mattered in Financial Services
Pascal Bouvier | MiddleGame Ventures | November 2026
I recently listened to a podcast with Tyler Cowen interviewing Jared Diamond and his recently published book: Profits, Prophets, Coaches, and Kings. Jared asks one question across politics, religion, business and sport: do individual leaders change history, or do they ride forces that would have produced the same outcome with someone else at the wheel? In other words, who are the true and irreplaceable leaders? The book opens with a truck that nearly crushed a chauffeur-driven car in March 1930; the passenger was Adolf Hitler. Diamond’s answer is neither romantic nor deterministic. Leaders matter when time, place and person line up, and the test is the counterfactual: remove the person and ask what happens next.[1][2]

I could not resist applying the test to the financial services industry. Whose contribution to financial services is irreplaceable? The exercise produced an uncomfortable finding for a venture investor. For roughly four of the five thousand years in which people have lent, borrowed, deposited and insured, the honest answer to “which individual mattered” is: almost none. Structures mattered. Temples, palaces, merchant families, legal codes and sovereign decrees built finance. The founder, the single person whose design choice we can point to, is a recent invention, and even today he is rarer than our industry’s mythology suggests. That inversion, from the structural of yore to the individual of today, is the thread of this article. It ends with a question about where the pendulum goes next.
A stele, not a startup
Let us start at the very beginning. Hammurabi’s code, carved around 1750 BCE, is the first surviving rulebook in which a sovereign sets the terms of credit. Paragraph 48 relieves a farmer whose crop has been destroyed by storm or drought: he “washes his debt-tablet in water” and gives his creditor no grain that year. Paragraph 117 limits debt bondage to three years; in the fourth the family goes free. Paragraphs 100 to 107 lay out the merchant-and-agent partnership in which a financier advances silver to a traveling agent, and the rules differ depending on whether the agent lost the capital through his own failure, in which case he repays it, or was robbed on the road, in which case he swears an oath and walks away. Paragraphs 122 to 125 are deposit law: no witnesses and no contract, no claim; a depositary who denies a witnessed deposit pays in full; a depositary whose house is robbed remains liable to his depositors.[3] Interest was capped at one fifth for silver and one third for grain, ceilings that persisted for centuries and that lenders promptly circumvented by charging the maximum on shorter loans.[4][5] Risk sharing, bailment, agency, rate caps, regulatory arbitrage: the whole modern menu is on a basalt stele tourists can view while visiting the Louvre.
Here is the point that matters for Diamond’s question. Hammurabi invented none of what is written on the stele. Interest-bearing loans, silver as a unit of account and collateral were centuries old when he ruled, and the 20 percent silver rate was set not by markets but by arithmetic, one sixtieth per month in a sexagesimal number system, which is why it barely moved for a thousand years.[4] What Hammurabi did was codify, standardize and publish. He was a regulator and an organizer of unwritten rules, not a creator.
Even the most consequential act of financial leadership in the ancient world was institutional rather than personal. Around 2400 BCE the ruler Enmetena of Lagash proclaimed a cancellation of debts, the earliest known, using the Sumerian word amargi, whose literal sense is a return to the mother and which came to mean freedom.[6] Babylonian rulers repeated the exercise at accession and in crises for a thousand years.[7] The scholar who has done most to recover this history, Michael Hudson, argues that clean slates were what kept agrarian societies from being eaten by compound interest.[7][8] For Diamond, this is close to a proof. Ancient financial leaders mattered at moments of reset, and the reset was a standing institution they inherited, not an idea they had.
Individual leaders?
Move from the palace to the market and the picture holds. The best-documented commercial society of the Bronze Age is the Assyrian merchant colony at Kanesh in Anatolia, which flourished around 2000 to 1750 BCE and left more than 23,000 clay tablets. Its long-distance trade was financed by what the Assyriologist Mogens Trolle Larsen describes as the naruqqum contract, a “money bag” in which several investors bought shares in a trader’s multi-year venture and divided the profits.[9] It is recognizably a joint-stock vehicle, and it was abandoned after roughly thirty years when the economic system that supported it collapsed, replaced by simpler venture trade.[10] William Goetzmann’s verdict on financial history fits: the tools of finance were repeatedly developed, forgotten and reinvented.[11] Nobody at Kanesh is remembered as the inventor of the naruqqum, the ancestor of the joint stock company. It was what merchant families did.
The same is true of the two other great pre-modern financial civilizations. Kautilya’s Arthashastra, the Indian treatise on statecraft compiled between the third century BCE and the third century CE, prices credit by risk with a precision the Bank for International Settlements might envy: 1.25 percent per month for ordinary loans, 5 percent for commercial lending, 10 percent for trade through forests and 20 percent for sea voyages.[12] A text written by one person who codified common practices to create a treatise on governance. Abbasid Baghdad in the eighth to tenth centuries ran suftaja bills of exchange honored across the caliphate, hawala transfers that still operate today, and the qirad or mudaraba profit-sharing partnership, which Abraham Udovitch argued in 1970 was the ancestor of the Italian commenda and therefore of the limited partnership every venture fund still uses, a lineage still debated.[13] The jurists who elaborated these instruments worked as schools, not as individuals. Even the celebrated court bankers of the caliph al-Muqtadir, Joseph ben Phineas and Aaron ben Amram, whom Walter Fischel described in 1933 as bankers in a quite modern sense, have on re-examination turned out to be tax-collection middlemen who never held official appointments.[14][15] Look closely at a pre-modern financial individual and a structured institution appears behind him.
When named individuals do surface, they are sovereigns or their officials making a rule or a reset. Solon in Athens in 594 BCE cancelled debts and forbade loans secured on a person’s body, ending enslavement for debt.[16] Xue Tian, the newly appointed prefect of Chengdu, re-instated the failed private jiaozi notes as a public currency in 1023, with provincial exchange bureaus, a 3 percent conversion commission, a ceiling of 1.25 million strings of cash per issue and 360,000 strings held in metallic reserve; one historian observes that China’s experience with paper money could have been a very short one had he decided otherwise.[17] Wang Anshi’s farm loans of 1069 offered peasants state credit at a maximum of 20 percent for the season against the 60 to 70 percent charged by private lenders, and were rolled back after his fall.[18]Johan de Witt, Grand Pensionary of Holland, priced life annuities on mortality mathematics in 1671 to fund a war budget, the first attempt to value a financial product actuarially, and was lynched in The Hague the following year.[19] These are Diamond’s leaders: an archon, a prefect, a chancellor, a statesman, each acting inside a structure at the moment the structure needed a rule. None of them was someone who created something from nothing.
I would venture to say the same is true if we draw from examples, we are more familiar with as Westerners. Double entry accounting was codified by individuals in Italy who worked within family structures. The first “modern” banks in the Renaissance were the pet projects of powerful Northern Italian traders. Both double entry accounting and modern banks arose in the 15th century. One exception can may be found with the modern central bank where, in the late 17th century, William Paterson proposed what would become the Bank of England.
What about joint stock companies? If we speed over ancient history, we find transferable shares existing in Rome, permanent pooled capital in Tudor England, the Dutch East Indian Company for codifying permanent limited liability shareholders and Victorian England making it legal for everyone. No one leader and creator emerges from this specific narrative.
The clerk and the mayor
The transition to the individual begins not with entrepreneurs but with managers and mayors. In 1823 in Pingyao, Shanxi, a former dye-shop accountant named Lei Lütai turned his employer’s internal remittance drafts into China’s first piaohao, or draft bank, Rishengchang, which grew to branches in some 35 cities and is said to have handled close to half of Chinese financial transactions at its peak.[20][21] Lei was the general manager, not the owner; the capital belonged to the Li family, and when he died at his desk in 1849 he had named an outsider rather than his own son as successor.[22] In Osaka, the shogunate licensed the Dojima rice exchange in 1730, the first thoroughly organized futures market with standardized clearing, more than a century before Chicago; it emerged from the needs of rice brokers and was supervised, and occasionally overruled, by the state.[23][24] In the Rhineland, a village mayor named Friedrich Wilhelm Raiffeisen converted a charitable association into a credit society in 1862 and founded the first rural cooperative bank at Heddesdorf in 1864; the model spread across Germany and, from 1895, the Netherlands, where Rabobank traces its roots to him.[25][26]
Notice what these three have in common. A manager designing governance for capital he did not own. A guild designing a market the sovereign then licensed. A mayor designing an ownership form for people the banks would not touch. The individual is beginning to matter through his creativity and his actions.
The “founder” arrives
The individual creator appears as a distinct historical type, and the financial services industry has organized its self-image around him ever since. His ascent was sporadic and started in the 18th century and accelerated in the 20th century. We have Adam Smith as the father of modern economics, Alexander Hamilton who laid the policy foundations that made the US a stable and investable destination, Mayer Rothschild who built the blueprint for global financial networks. Benjamin Graham who helped transforming investing from gambling into a disciplined financial practice could very well lay the claim to be a true creator in financial services.
Taking a closer look at some of the individual creators we see the following:
Dee Hock did not design a product. In 1970, with Bank of America’s licensed BankAmericard program collapsing under fraud and inter-bank chaos, he persuaded the bank to give up ownership of it and formed National BankAmericard Inc., a member-owned association in which competing banks shared authorization, clearing and settlement standards under rules no single institution could rewrite; it became Visa in 1976.[27][28] The plastic already existed. The agreement did not. Hock later coined the word “chaordic” for what he had built and spent his retirement arguing that the constitution, not the company, was the invention.[27]
Jack Bogle did not invent the index fund; institutional versions existed from 1971.[29] What he did in founding Vanguard on May 1, 1975 was to structure the manager as the property of the funds themselves, so that investors owned the company that served them. He called it the Vanguard experiment. The first index fund for individuals followed on August 31, 1976; it raised $11 million against a $150 million target and was ridiculed on Wall Street as a sure path to mediocrity.[30][31] Vanguard managed roughly $12 trillion at the end of 2024.[31] Remove Bogle and the world still gets index funds. It does not get a mutualized, fee-crushing owner of them.
Muhammad Yunus’s experiment in the village of Jobra in 1976, financed by a commercial bank loan he personally guaranteed, became Grameen Bank by government ordinance in 1983; the bank is 92 percent owned by its borrowers.[32]Group liability and borrower ownership were design choices, not inevitabilities.
Satoshi Nakamoto is the purest case we could wish for. On October 31, 2008 a pseudonymous author posted to a cryptography mailing list a nine-page paper solving the double-spending problem without a trusted third party, a problem cryptographers had circled for two decades.[33][34] The person is unknown. The design choice is unambiguous. Whatever one thinks of the outcome, no structural account explains why that paper appeared when and how it did.
And then the cases that look individual and turn out structural. M-Pesa, launched by Safaricom in March 2007, is credited to two Vodafone executives, Nick Hughes and Susie Lonie, who ran the 2005 pilot; but it was born of a British government challenge fund for financial inclusion, commercialized by a Kenyan operator, and the pilot’s customers had already begun using a loan-repayment tool to send money to one another before anyone designed a remittance product.[35][36] Islamic banking has founders, Ahmad El-Najjar at Mit Ghamr in 1963 and Saeed Lootah at Dubai Islamic Bank in 1975, and is today a $4.4 trillion industry; yet interest-free banking experiments appeared in Pakistan, Malaysia, Egypt and the Gulf within a couple of decades of one another, which is the signature of circumstance, oil wealth and religious revival, rather than of any one person.[37][38][39] India’s UPI was launched on April 11, 2016 by the central bank governor with Nandan Nilekani beside him as adviser, and processed 24.51 billion transactions across 752 banks in August 2026 alone; it is the work of a payments utility and a technocrat who chose a public architecture over private wallets.[40][41][42]Nilekani is the closest thing our era has to Xue Tian: an official whose design choice mattered, not a founder.
It seems that the industrial revolution whose historical arc led us to today elevated individuals and their achievements and that in most cases, even if these visionaries helped bring about major trend, they were also tributaries to the signs of their times.
Why the pendulum swung
Three forces explain why finance went from structural to individual.
The first is the record. We know the names of ancient financial actors when a state chose to preserve them, on a stele or in a court chronicle; merchants survive as families and archives. Capital markets, the corporate form and the financial press did for the modern founder what the stele did for Hammurabi. They made individuals legible, and they made the individual the unit in which history is told.
The second is the retreat of the sovereign. From Enmetena to Wang Anshi to de Witt, the person who set the terms of credit was a ruler or his official, and the innovations that mattered were rules and resets. The liberal order of the nineteenth and twentieth centuries handed the design of credit, payment and investment structures to private actors, and the founder is what that handover looks like when it is written up. Bogle, Hock and Yunus were doing in private law what sovereigns had done in public law: writing the constitution of a financial arrangement.
The third is technology. Software collapsed the cost of writing and distributing a rule-set. A constitution for a payment network once required a room full of bankers and years of Hock’s barnstorming; in 2008 it required a PDF and a mailing list. Nakamoto could exist only in a world where one person can ship a structure to everyone at once.
Will the pendulum swing back?
What if the pendulum were to swing back from individuals to institutions and/or the sovereign? The sovereign is returning as the designer of financial structure in part due to geopolitical concerns and sovereignty goals. The GENIUS Act writes the capability to freeze and burn into the definition of a lawful US stablecoin; MiCA regulates reserves and redemption for euro tokens; the European Parliament has cleared a digital euro designed to forget; India’s state-built rail is the one private wallets ride on. We wrote about the first of these in Money with a Memory and about its fiscal logic in The Dollar’s Waning Privilege.[43][44] Put them together and the pattern is Hammurabic: the state codifying the terms of money and credit and publishing them for all to see. The clean-slate rulers set interest caps; ours set freeze orders and reserve rules. The individual as creator and leader’s “century” may prove to have been an interlude between two structural eras?
If Diamond is right that leaders matter when time, place and person align, then finance is at exactly such a moment, because the structure is being rewritten. The individuals who will matter come in two kinds, and both have precedents in this history. The first are the Xue Tians and the Nilekanis inside the state, whose architectural choices, an offline privacy mode here, a public rail there, will bind private innovation for decades. The second are the Hocks, who design agreements among rivals that can survive the state’s return because they were built to sit alongside public rules rather than around them.
MiddleGame Ventures’ stance
For us the history reads as a discipline rather than a curiosity. We back exceptional individuals for their potential operational acumen and resilience, since that is what early-stage venture is, but we underwrite structures. The question we ask a founding team is not only who they are, what they want to achieve and what the product does but what agreement it encodes: who owns the network, who can change the rules, who bears the loss when the caravan is robbed on the road. Hammurabi’s paragraphs 102 and 103 remain a serviceable term sheet. In other words what also matters to us is what we call market structure and where that market structure will evolve.
We draw three conclusions for our own deployment. First, the most durable financial companies of the last fifty years were constitutions before they were products, and we look for founders who understand that governance and ownership design is one of the moats, not a legal afterthought. Second, the return of the sovereign as architect is a European advantage rather than a threat. Europe’s historical strength in finance has been institutional design, and a digital euro built to forget, an EU identity wallet built to disclose the minimum, and MiCA-compliant euro instruments are structures that private companies can build on with a regulatory certainty their American peers lack. Third, the convergence we invest behind, digital wallets, tokenized assets and intelligent automation coming together onchain, is itself a constitutional question. A chain is a rule-set every participant accepts in advance; the founders who will matter in that world are the ones designing the agreement among wallets, issuers and, increasingly, autonomous agents, not the ones shipping another interface.
Diamond’s leaders mattered at resets. Finance is in one. We intend to be on the side of those who write the rules well.
