He gave the world's biggest brands a way to see something they had never seen: the tens of thousands of suppliers hiding behind their own products.
Pick up a leather handbag. Somewhere behind it sits a tannery, and behind the tannery a slaughterhouse, and behind that a ranch with a name and a postcode. The brand on the label usually has no idea. Leonardo Bonanni built the software that finds out anyway, often in a matter of weeks, for a company that started knowing nothing about where its leather came from.
That software is Sourcemap, and Bonanni runs it as founder and CEO from Lower Manhattan. It is the kind of tool that sounds dull until you realize what it touches: forced labor laws, deforestation rules, the cocoa in chocolate, the cobalt in batteries, the down in a winter coat. When a regulator in Brussels or Washington decides a company must prove where its raw materials originate, Sourcemap is one of the few systems that can actually draw the line on a map.
His pitch for how it works is disarmingly simple. "It works similar to a social network like LinkedIn," he says. "Companies invite their suppliers, who invite theirs, until every component has an origin." A brand maps its direct suppliers, those suppliers map theirs, and the chain unspools link by link until it reaches dirt, ore, or animal. The genius is not the visualization. It is the social mechanic that gets thousands of suspicious, far-flung vendors to add themselves to a graph they were never part of before.
"Companies had never mapped their supply chains, especially the indirect suppliers' suppliers - which number in the tens of thousands."
Sourcemap did not begin as enterprise software. It began as a PhD experiment. In 2008, working inside the MIT Media Lab's Tangible Media Group, Bonanni started building what he described as a "Wikipedia for supply chains" - an open website where anyone could trace the origins and impacts of everyday products and share what they found. It was a research artifact about transparency, not a business plan. He was a designer studying green and sustainable product design, more interested in the question than in a revenue model.
The handle he chose at the Media Lab tells you something about how he saw the work. It is "amerigo," after Amerigo Vespucci, the navigator the Americas are named for. A cartographer's joke from a man about to spend a career drawing maps of territory nobody had charted.
Then the ground moved. In March 2011 the Tohoku earthquake and tsunami devastated Japan and ruptured supply chains that ran through it. Brands suddenly, urgently needed to know which of their products depended on factories now underwater. They came to Bonanni and his research demo. One month after the disaster, he founded Sourcemap Inc. The thesis had become a company almost overnight, pulled into existence by the exact problem it was built to study.
"Sourcemap started as my PhD project at the MIT Media Lab in 2008 - the initial goal was a Wikipedia for supply chains."
The early years were shaped by disasters rather than sales cycles. In 2013 the company moved to Lower Manhattan after being contracted to map supply chains for Superstorm Sandy recovery work under New York's Bloomberg administration. The pattern repeated: when systems break, the value of knowing how they were wired becomes obvious to everyone at once.
Bonanni leaned into that. He testified before the French Senate in 2011 and before the US Senate in 2021, both times on the technology of traceability - how it works, what it can prove, and why governments should care. It is an unusual second act for someone who once designed home appliances and medical devices. Before MIT, that is what he did: architecture, product design, and UI/UX engineering for appliances, diagnostic equipment, and the kind of objects whose interfaces you only notice when they fail.
The recognition followed the work. Sourcemap landed on Time Magazine's Best Inventions list in 2022 and was named among Fast Company's Most Innovative Companies in 2023. Bonanni himself has been counted among Ethisphere's 100 Most Influential People in Business Ethics and Bloomberg Businessweek's Most Promising Social Entrepreneurs. In 2023 he took the idea to a wider stage at TEDxMilano, explaining in Italian how and why to map a supply chain - and raised a $20M Series B that pushed the company's total funding past $31M.
Ask Bonanni who drives supply chain transparency and his answer is counterintuitive. It is not the conscientious shopper studying a label in the aisle. He argues that the strongest pull comes from recruiting and reputation: the best people want to work for companies that can stand behind where their products come from. Consumers, in his view, should not have to wade through an entire supply chain. Brands should pick the few things that matter most to their audience and be honest about those.
That clarity about motive is part of why the company reads less like a sustainability nonprofit and more like infrastructure. Its customer list spans food, apparel, pharmaceuticals, electronics, and automotive - industries where a single hidden supplier can mean a recall, a fine, or a headline. The keyword cloud around Sourcemap reads like a regulatory weather report: forced labor, deforestation, conflict minerals, chain of custody, due diligence, ESG. Each of those is a law somewhere, and each law is a reason to buy a map.
"Disclosure is the ultimate aim of traceability and transparency for all of our customers."
He is careful about how much of that disclosure should land on the shopper. Pushing an entire bill of materials at a customer is not transparency, it is noise. The better move, he argues, is for a brand to identify the handful of issues its audience genuinely cares about - whether that is the cocoa, the cotton, or the conditions in a single factory - and communicate clearly about those. The full graph stays in the background, doing the work of compliance and risk, while the front of house tells a story people can actually hold in their heads.
Bonanni has watched the same dynamic play out for more than a decade: visibility feels optional until something snaps. The Tohoku tsunami created the company. Superstorm Sandy moved it to New York. And the COVID-19 pandemic, he says, redoubled corporate investment in supply chain digitization and mapping, because executives suddenly needed to know which suppliers were still standing and which were about to disappear. Disruption is the best salesperson Sourcemap has ever had, and there is always more of it coming.
He has also been candid that the work is bigger than any one startup. He has argued that the odds of governments discovering the small companies building real traceability tools are "almost zero," and has called for the public sector to convene the people developing technological solutions rather than leaving them to be found by accident. It is a notably collaborative stance from a founder - less about cornering a market than about getting an entire practice adopted, even if competitors come along for the ride.
Bonanni's stated ambition is blunt: "Supply chain mapping has to become the norm." He talks about extending it into aerospace, defense, personal care, and electronics - sectors where visibility is still primitive. The pitch has shifted over the years from idealism to inevitability. The pandemic, he notes, redoubled corporate investment in supply chain digitization, because companies finally felt what it costs to not know whether a critical supplier is about to vanish.
There is a quiet consistency to the whole arc. A designer who studied how people connect to objects built a tool that connects companies to the origins of their objects. The MIT side project, the tsunami, the storm, the senates, the enterprise contracts - they all point at the same stubborn idea he has been chasing since 2008: that every product should be able to tell you where it came from, and that someone ought to build the map. He did. He is still drawing it.
No single company can map its own supply chain alone. Sourcemap's trick is to make every supplier do its small part of the work.
A brand maps its direct suppliers and invites them onto the platform.
Each supplier invites its own suppliers. The chain unspools link by link.
It keeps going until every component reaches a raw material with a real-world location.
