From capturing carbon dioxide out of thin air at Google X, to capturing sales orders out of fax machines at manufacturers and distributors worldwide - Darren Bonnstetter runs toward the hard problem, wherever it lives.
Darren Bonnstetter · CEO, Conexiom
There is a specific type of executive who gets brought in when a company has strong fundamentals, serious capital behind it, and a technology inflection point it hasn't fully seized. Darren Bonnstetter is that executive. When Conexiom's founding CEO John McNeill stepped back in August 2025, the board didn't go looking for a conventional SaaS operator. They went looking for someone who had already built a company from a scientific moonshot at Google X, someone who understood that the gap between a working prototype and a market-changing platform is entirely an execution problem.
Conexiom is not a company most consumers have heard of. That's by design. It lives inside the machinery of global commerce - specifically, the part where a manufacturer receives a purchase order from a distributor, and needs to get that order into their ERP system without a human typing every line. For decades, people typed those lines. Bonnstetter's job is to make sure nobody ever has to again.
The company's platform uses AI to read orders from any format - fax, PDF, email, EDI, portal - and push clean, validated data directly into ERP systems like SAP. Sounds unglamorous. The economics are not. Conexiom already serves 16 of the top 20 global distributors. Its network spans more than 100,000 industrial buyers and suppliers. The company has raised $170 million in total, backed by Warburg Pincus, ICONIQ Capital, and Luminate Capital Partners. Annual revenue sits around $28.7 million with 210 employees. Bonnstetter stepped into something that already works - and now has to make it inevitable.
"Distributors and manufacturers are the backbone of global commerce," Bonnstetter said when the appointment was announced. "Our goal is to help them operate with more speed, precision, and agility through AI-powered automation." The language is measured. The stakes are not.
"Bold innovation only succeeds when paired with disciplined execution."- Darren Bonnstetter, CEO, Conexiom
Before Conexiom, Bonnstetter spent roughly three years at 280 Earth, a company he co-founded with John Pimentel and Jacques Gagne after incubating the idea inside Google's X lab - the same facility that incubated self-driving cars and delivery drones. 280 Earth's specific audacity: pull CO2 directly out of the air using waste heat from data centers and industrial facilities. It's named after 280 parts per million - the pre-industrial atmospheric CO2 concentration that Earth's climate was calibrated to.
Under Bonnstetter's leadership, 280 Earth raised a $50 million Series B in May 2024, with Alphabet - Google's parent company - participating as an investor alongside Builders VC. The company operated a pilot facility in The Dalles, Oregon, and projected CO2 removal costs of $200 per ton by 2028. Those numbers attracted Sergey Brin's attention. By 2024, 280 Earth had graduated from X and become a fully independent company - one of a very short list of moonshots to successfully make that transition.
280 Earth's pilot operates in The Dalles, Oregon - a city that hosts some of the largest data centers in the world, including major Google facilities. The symmetry is intentional: use the excess heat from the same infrastructure that generates digital commerce to remove the emissions that commerce produces. Bonnstetter helped architect that irony before moving on.
The Conexiom role is, in some ways, the inverse of 280 Earth. Climate tech runs on long timelines, patient capital, and scientific bets. B2B SaaS runs on net revenue retention, annual recurring revenue, and land-and-expand. Both require the same underlying muscle: turning an insight into a system that scales. Bonnstetter's career has been a long exercise in exactly that.
His formative training came at General Motors, where he spent more than eleven years in engineering and management roles, including time in Brazil. GM saw something in Bonnstetter early enough to offer him one of its most selective benefits: the GM Fellowship Award. He received it twice - once to attend Stanford for a Master of Science in Mechanical Engineering, and again to attend Harvard Business School for his MBA. Two elite graduate programs, both funded by a single employer. The distinction is unusual enough that it's worth dwelling on. GM effectively handed Bonnstetter both the technical toolkit and the strategic vocabulary he would later use to build companies.
After GM came AlixPartners, the restructuring and performance improvement firm. As a Director in the Performance Improvement group, Bonnstetter ran turnarounds across telecom, automotive, steel, retail, and distribution. AlixPartners does not specialize in comfort. Its clients are usually in distress or in transition - companies where the old playbook has failed and a new one needs to be installed fast. The experience gave Bonnstetter a pattern library of how industries break and how they recover.
Then Google X. Then 280 Earth. Then Conexiom.
The through-line is a preference for situations where complexity is the moat - where the problem is hard enough, the domain specific enough, and the execution requirements demanding enough, that most operators would rather not be there. Supply chain order processing turns out to be exactly that kind of problem. Manufacturers and distributors have built decades of bespoke workflows around moving paper and PDFs between trading partners. Untangling that and replacing it with AI-driven automation requires not just software, but change management, integration depth, and the credibility to walk into a Fortune 500 distributor and convince their operations team to trust a machine with their order flow.
The $130M Private Equity raise in October 2021, led by Warburg Pincus, gave Conexiom the runway to expand beyond its core EDI replacement use case. AI capabilities have matured enough that the company can now handle unstructured, handwritten, and multi-format orders - not just clean electronic data. The move to an AI-native platform, under Bonnstetter's direction, is the next phase of that bet. The question isn't whether the technology can do it. The question is whether the company can sell, implement, and retain at the rate the capital and market position warrant.
Bonnstetter lives in Palo Alto, California - a geographic choice that puts him close to the venture and private equity networks that matter for a company in growth mode, while keeping Conexiom's operational center in Vancouver, British Columbia. The arrangement is common among executives of well-funded Canadian tech companies with U.S. market ambitions.
What Conexiom is building under Bonnstetter is a network effect play dressed up as a workflow tool. Every manufacturer and distributor that runs on the platform makes the network denser, the training data richer, and the switching costs higher. The 100,000+ buyers and suppliers already in the network didn't get there by accident. They got there because the economics of touchless order processing - faster cycle times, fewer errors, lower headcount per order - are compellingly straightforward once you see them.
Bonnstetter's challenge is to make Conexiom the obvious answer before competitors can close the gap. His background suggests he understands that the hardest part of that task has nothing to do with the technology. It has to do with the humans on both sides of every purchase order.

General Motors funded Bonnstetter's graduate education in its entirety. The GM Fellowship is competitive; receiving it once is noteworthy. Receiving it for both a Stanford engineering graduate program and Harvard Business School is documented in his profile as a "double" recipient - and puts him in a very small cohort of executives who held serious technical and business credentials before the age of 35.
The GM Fellowship Award is granted to employees General Motors identifies as high-potential talent. Bonnstetter's designation as a "double recipient" - to both Stanford and Harvard - while still employed at GM, is the kind of biographical detail that signals unusually early recognition. It also meant he returned to GM each time, rather than pivoting to consulting or finance after graduation. He stayed long enough to do it again.
Purchase orders arrive as PDFs, faxes, emails, EDI files, and portal entries. Conexiom reads them all - including handwritten orders - using AI and OCR, without requiring a human to key in the data.
The extracted order data is mapped, validated, and pushed directly into ERP systems including SAP. The platform handles data enrichment, anomaly detection, and exception management.
Order performance analytics, cycle time tracking, exception pattern recognition, and benchmarking tools give operations teams visibility into exactly where friction lives.
With 100,000+ buyers and suppliers on the platform, Conexiom has the data advantage to improve automation accuracy over time. Every order processed makes the next one smarter.
Order automation is one of those problems that looks small until you price the alternative. A typical manufacturer processes thousands of purchase orders per month. Each manual order touches a human being - someone who reads the document, interprets the line items, checks part numbers, validates quantities, and enters the data into an ERP. The error rate across that process is high. The cycle time is slow. The labor cost is real. Conexiom eliminates that entire step for its customers.
Under Bonnstetter's direction, the company's stated goal is to become fully AI-native - meaning the platform doesn't just automate the order capture step, but applies machine learning continuously to improve accuracy, reduce exceptions, and surface insights about order patterns that operators didn't know to look for. For manufacturers and distributors running on thin margins in a global supply chain, the difference between a 95% touchless rate and a 99% touchless rate is measurable in headcount, delivery speed, and customer satisfaction.
Before Conexiom, Bonnstetter was building something considerably more unusual. 280 Earth is named after a number: 280 parts per million, the concentration of CO2 in Earth's atmosphere before the Industrial Revolution. Getting back to that number, or something approaching it, is one of the defining technical challenges of the 21st century.
Bonnstetter and his co-founders - John Pimentel and Jacques Gagne - incubated the idea at Google X, the company's secretive R&D lab. The core technology: direct air capture of CO2, powered by waste heat from industrial facilities. The thesis was that enormous amounts of low-grade heat - from data centers, steel mills, chemical plants - are currently wasted into the atmosphere. 280 Earth proposed to use that heat as an energy source for CO2 removal, dramatically lowering the cost versus conventional carbon capture approaches that require dedicated energy inputs.
The pilot facility was built in The Dalles, Oregon - home to some of the world's largest data centers. The geographic logic was intentional and elegant. The company projected removing CO2 at $200 per ton by 2028, a target that - if achieved - would make 280 Earth cost-competitive with other offset mechanisms and attractive for corporate buyers under regulatory pressure.
Sergey Brin backed it. Alphabet invested in the $50M Series B. The company graduated from Google X in 2024 - a milestone that very few X projects ever reach. The graduation means 280 Earth stood on its own: independent governance, independent funding, independent destiny. Bonnstetter then moved on to Conexiom, leaving 280 Earth as a going concern with a clear roadmap and a well-capitalized balance sheet.
The pivot from climate tech to supply chain automation could look like a non-sequitur. It isn't. Both are fundamentally systems-optimization problems. Both require convincing large industrial organizations to trust new technology with core operations. Both depend on the ability to translate complex science or engineering into an economic proposition that a CFO can defend to a board. Bonnstetter's particular skill, across all of these contexts, appears to be exactly that translation.
Google X graduates are rare. The lab has incubated Waymo (self-driving cars), Wing (delivery drones), Verily (life sciences), and Loon (internet balloons). 280 Earth joins a short list of projects that made the transition from internal experiment to externally funded company. Bonnstetter has "graduated a Google moonshot" on his career record - not many people do.
GM Fellowship recipient - to both Stanford and Harvard. That double is unusual enough that Bonnstetter's bio documents it specifically. Most executives get one. He got both, while still employed at GM between each degree.
Parts per million of CO2 in the pre-industrial atmosphere. Bonnstetter's previous company was literally named after the number humanity is trying to get back to. Most CEOs name companies after their founders or a clever portmanteau. This one named it after a geochemical measurement.
Countries Bonnstetter has worked in: the United States, Brazil (during his GM years), and now effectively Canada through Conexiom's Vancouver headquarters. His career has been multinational since before it was fashionable to call it that.
Per ton - the CO2 removal cost target 280 Earth was working toward by 2028, with Sergey Brin and Alphabet watching. Bonnstetter was responsible for the engineering, commercial, and financial strategy to hit that number before he moved on.
Years at General Motors. Bonnstetter's career started in the world's largest industrial machinery, not in a startup. He stayed for more than a decade, went to graduate school twice on GM's budget, worked internationally, and then pivoted to turnaround consulting. The roots are deeply operational.
Buyers and suppliers on the Conexiom network - the inheritance Bonnstetter is working with. That's a real network effect with real switching costs. The platform he now runs is already embedded in the operational DNA of thousands of industrial businesses.
Bonnstetter's two known public quotes both carry the same internal logic: innovation without execution is noise. "Bold innovation only succeeds when paired with disciplined execution" is the more explicit version. His description of manufacturers and distributors as "the backbone of global commerce" - and the goal of making that backbone faster - is the applied version.
This isn't a man who came from software. He came from manufacturing, from turnarounds, from a climate science startup where the consequences of a failed experiment were measured in investor capital and atmospheric CO2, not in server uptime. The industries he has operated in - automotive, steel, retail, distribution, carbon capture, order automation - all share a characteristic: they are unforgiving to imprecision. A wrong part number on a purchase order causes a shipment failure. A wrong energy calculation in a carbon capture process causes cost overruns. The discipline required to operate in physical systems translates, for Bonnstetter, directly into how he thinks about software businesses.
At Conexiom, that means the AI isn't a feature. It's the architecture. The company's move to an "AI-native platform" under his direction is not about adding a chatbot to a legacy product. It's about rebuilding the core intelligence of the platform to improve continuously on order accuracy, exception prediction, and process optimization. The same impulse that made 280 Earth interesting - using existing industrial infrastructure rather than building new - appears at Conexiom in the form of meeting customers where their data actually lives: in ERP systems they've run for 20 years, with trading partners who still send orders by fax.
The personality traits that emerge from his career arc - systems thinking, comfort with complexity, a preference for hard problems in established industries, a willingness to build things that don't yet exist - are consistent across every role. General Motors didn't produce a conventional automotive lifer. It produced someone who used GM as a graduate school, then exported that education into every industry he touched afterward.
