Amex Global Business Travel: The World’s First AI Take Private with Long Lake CEO Alexander Taubman

The world’s first AI-take-private just proved that AI can revolutionize the real economy. Long Lake Management co-founder and CEO Alexander Taubman joins Elad Gil to discuss his firm’s agreement to acquire the legacy platform American Express Global Business Travel (Amex GBT) in a deal valued at $6.3 billion. Alexander explains the mechanics of AI-driven roll-ups, and why Long Lake chooses to acquire and transform businesses rather than simply selling them software. He also talks about how Long ✦ AI generated

Mechanism

Long Lake's AI platform Nexus sits between models and business data/workflows, with roughly 80% shared infrastructure across verticals and the remaining 20% customized per industry through applied AI engineering.

Taubman describes the architecture of Long Lake's Nexus AI platform: 80% is shared horizontal infrastructure, while 20% involves vertical-specific deployment work like mapping workflows, cleaning data, and integrating systems so AI models can access them effectively.

transcript

Alexander Taubman: So we've taken an approach since the beginning of investing very heavily in our horizontal AI platform, which we call Nexus. I'd say roughly 80% of the infrastructure is shared across the verticals. And then there's a lot of work to take it and deploy it into those end markets. And the deployment involves mapping workflows, understanding data sources, cleaning up data sources, integrating with them to make them easier for the models to access. And sort of our next platform sits in between the models on one side, and we're model agnostic, and the data sources, the skills, the workflows of the business. And so that takes a lot of customization and significant applied AI engineering capabilities, which we've built at Long Lake.

Claim

We focus on driving growth and customer experience through AI, not cost cutting, and this creates a positive-sum outcome where more productive people lead to more jobs and faster growth.

Taubman argues that Long Lake's AI platform is deployed to drive growth and customer experience, not to cut costs. More productive employees enable the company to grow faster, create jobs, and generate better customer outcomes, making AI a positive-sum technology.

transcript

Alexander Taubman: We actually invest very heavily in growth. We're actually not really, you know, we're not focused on cost saving. We're actually focused on driving growth and customer experience. That's our big, and what we've seen is a much more powerful model because it's our view of AI is it's incredibly positive sum. I know this is a little bit of a narrative violation, but we actually think AI makes people more productive and we have more productive people, you want more of them. When your customers are happier, you grow faster, you actually create jobs and everybody wins. And so we're seeing this in our companies. We're fastest growing company in the HOA industry now. We are growing organically. When we invested in the businesses, they're typically growing 0 to 5% a year in terms of volume. We're now growing 20 plus percent a year. And that's because we've made our team members, we've given them extra capacity to go and serve more customers. We actually have better, more attractive customer acquisition economics because we can serve those customers at incrementally lower costs with better products and services.

Claim

AI makes employees dramatically more productive, which creates a virtuous flywheel: happier customers drive faster organic growth (from 0-5% to 20%+ annually), which lets the company pay employees the most in their industry, which attracts and retains top talent, which further improves customer outcomes.

Taubman rejects the narrative that AI eliminates jobs. Instead, he describes a positive-sum flywheel: AI gives employees superpowers, reducing mundane work from ~25-30% of their day. This makes them dramatically more productive, allowing the company to grow 20%+ organically (vs. 0-5% before), pay above-market wages, attract top talent, and retain customers through better service.

Alexander Taubman: We're actually not really, you know, we're not focused on cost saving. We're actually focused on driving growth and customer experience. That's our big, and what we've seen is a much more powerful model because it's our view of AI is it's incredibly positive sum. I know this is a little bit of a narrative violation, but we actually think AI makes people more productive and we have more productive people, you want more of them. When your customers are happier, you grow faster, you actually create jobs and everybody wins. [...] when we invested in the businesses, they're typically growing 0 to 5% a year in terms of volume. We're now growing 20 plus percent a year. And that's because we've made our team members, we've given them extra capacity to go and serve more customers. [...] This is the vision, Long Lake. We want to basically be the best place to work in every industry that we operate so we can give the best people the best tools with the best customers and that flywheel becomes self-perpetuating. Because if you now leave Long Lake or you leave one of our partner companies to go to a competitor, you have to start doing all this mundane work again. That you 25% of your day, 30% of your day, you have to go do that again. [...] And by the way, we can pay people the most. Because they're the most productive, they're actually making more money. And we're delighted about that. So we can pay you the most, give you the best tools, and we're growing the fastest.

Mechanism

We acquire companies rather than selling them software because ownership creates deeper alignment, a tighter feedback loop between engineers and end users, and better business outcomes than a vendor relationship can deliver.

Taubman explains Long Lake's choice to acquire companies rather than sell AI software as a vendor. By owning the businesses, Long Lake's engineers sit alongside team members in the field, creating a tight feedback loop that drives better solutions and outcomes than selling software externally would allow.

transcript

Alexander Taubman: We think that you can drive better win-win business outcomes with deeper alignment. And so by actually owning the companies and owning those customer relationships directly, we can drive better results. Software companies are wonderful. We partner with many of them. But when you're just selling software and you don't actually then care what happens with the business outcomes, you just don't see the same business outcomes. Our team views our employees and our team members in the field as the customer. And that feedback loop internally, that's the other point is we have a much tighter feedback loop. So, you know, the old Skunk Works thing of you want the engineers in the factory to be co-located so you can have more innovation. That's what we have at Long Lake. So our team members and our engineers are together in the field all the time. I think there's, of our engineering team, they're probably in 20 different states right now, sitting with team members across our architecture business, across our HOA business, across our HR services, or specialty tax business. And so there's sort of, and there's a deep amount of change management that's involved. So this is a lot of, sitting with the team members, understanding their pain points. And so there's a real like solutions orientation of how do we take the pain point, and then we build a tool within Nexus to solve it. And that feedback loop is really important.

Claim

AI-driven acquisition is superior to selling software because ownership creates tighter feedback loops between engineers and end-users, deeper alignment on business outcomes, and the ability to enforce change management — all of which are impossible when merely selling software to a company.

Taubman argues the traditional Silicon Valley playbook of selling software fails for AI adoption because vendors can't drive change management or create tight engineer-user feedback loops. By owning the companies, Long Lake's engineers sit alongside employees in the field, co-located like Skunk Works, enabling rapid iteration on real pain points.

Context

Our founding team was purpose-built to combine M&A, applied AI engineering, and change management — three competencies that rarely coexist — because we recruited through deep personal networks across top tech companies and private equity firms.

Taubman explains that Long Lake was purpose-built from day one to combine M&A expertise, AI engineering, and change management. The first 20 people came through the founders' personal networks, spanning companies like Palantir, Ramp, Robinhood, and top PE firms like GTCR and Blackstone, which is rare because business and technical networks are usually separate.

transcript

Alexander Taubman: Yeah, so because we were purpose-built from day one to kind of be this cross-functional company with technology and DNA, change management, and M&A, we were able to attract, you know, the right type of people from network. And so I think 100% of our first 20 people were through network. We knew them really well. And people from, you know, places like Palantir, Ramp, Robinhood, some of the top glean, some of the top sort of modern AI and data companies. And so, Rasmus, our co-founder and CTO, he and I were connected through one of our, early investors and board members who've, we've all known each other for kind of 15 plus years. We all started our careers together. And it's really rare, by the way, I think for many business people to have those deep technical networks, like what I've observed is that often these are separate worlds. And technologists are very bad at hiring business people early on, at least in their careers. And vice versa, business people tend to be awful at hiring engineers. And so you end up with these mismatches on the early teams.

Mechanism

Long Lake was purpose-built from day one as a cross-functional organization combining three rare competencies — private equity M&A, applied AI engineering, and change management — by recruiting through deep personal networks from elite firms like Palantir, Ramp, Robinhood, Glean, GTCR, Blackstone, and TPG.

Taubman explains how Long Lake solved the three-competency problem (M&A, AI engineering, change management) that most AI-rollup attempts fail at. The founding team was recruited entirely through 15+ year personal networks, pulling engineers from Palantir/Ramp/Robinhood/Glean and M&A talent from GTCR/Blackstone/TPG — people who left elite firms because those firms weren't AI-native.

transcript

Alexander Taubman: Yeah, so because we were purpose-built from day one to kind of be this cross-functional company with technology and DNA, change management, and M&A, we were able to attract, you know, the right type of people from network. And so I think 100% of our first 20 people were through network. We knew them really well. And people from, you know, places like Alantir, Ramp, Robinhood, some of the top glean, some of the top sort of modern AI and data companies. [...] our private equity team comes from, our M&A team comes from top private equity firms. So Manny, one of our co-founders and M&A lead, came from GTCR. He actually worked on the most profitable deal in their history the month before he left to come to Long Lake. [...] We have folks from Blackstone, TPG, HIG. And mostly the reason they come to Long Lake is because, you know, even though these firms are extraordinary firms at what they do, they're not AI native. And so I think for those subsegment of those M&A professionals that really believe in our thesis, there's not many places that look like Long Lake today.

The Amex GBT acquisition ($6.3 billion, 111-year-old company) represents the world's first AI take-private, targeting a mission-critical service with high cost of failure where AI can give travel counselors superpowers for faster disruption resolution and better customer outcomes.

Taubman frames the Amex GBT deal as the first-ever AI take-private. The company, founded in 1915 to evacuate travelers' check customers from WWI Europe, has navigated a century of technology shifts. Long Lake identified corporate travel as a high-value vertical because it's mission-critical with high cost of failure, and plans to double down on GBT's existing AI transformation by giving travel counselors AI superpowers.

transcript

Alexander Taubman: This is a 111 year old company. It was started in 1915 by American Express as a way for them to get their travelers' checks customers out of Europe during World War I. [...] So I mean, these are businesses that have navigated a century plus worth of technology transformation. And so, and we think they're going to be, it's going to be an extraordinary franchise for another century to come. [...] the reasons are, it's a mission critical service. It's high cost of failure. Most trips are revenue generating. [...] the customer trust that this franchise has built over 100 years is really extraordinary. [...] our vision is to really double down on the company's existing AI transformation strategy. And we see it as, any industry that we operate in, we see our Nexus platform as giving our team members superpowers, deliver better customer outcomes, faster response times, faster disruption resolution. And imagine basically you're a travel counselor with AI superpowers. That's kind of the future we envision for MXGBT's customers.

Prediction

We aim to be a permanent, long-term owner of businesses — like a Berkshire Hathaway for the services sector — because the multi-year AI transformation flywheel compounds over decades and selling after building that advantage makes no sense.

Taubman distinguishes Long Lake's approach from traditional private equity's short-term, cost-cutting playbook. He frames their model as long-term permanent ownership inspired by Danaher and Berkshire Hathaway: the AI-driven flywheel of better tools → better people → better customer outcomes → faster growth takes years to compound, and selling after building that advantage would be irrational.

transcript

Alexander Taubman: Well, look, I think it's a really big market opportunity. This is 20 plus trillion TAM, like I said before. And I think we'd like to be the market leader in every segment that we're operating in. And I think there's a lot of segments to potentially add value to. So part of what inspired us always about the Danahers of the world is they were able to compound, they developed a differentiated operating model. In their case, started manufacturing and then life sciences, but they were always able to drive better growth, better customer satisfaction, better employee retention, and ultimately better productivity. And that allowed them to continually consolidate all these industries over a long period of time with a lot of outperformance. And so our vision is to sort of follow in the footsteps of some of those great companies and do it within the services sector and with our sort of AI platform as our advantage. And I do think that there's something about the long-term nature of what we're doing. It's really hard. What we're doing is actually really hard. And doing it, you can't do this in a year. You can't do this even in two years, three years. This is a multi-year transformation. These are sort of compounding effects, where as we talked about earlier, as you sort of give your people better tools, you get better people, and then you can pay them more, and then they can deliver better customer outcomes, and then you can grow faster. That's not a one-month, two-month cycle. That's a two, three, four, five-year transformation cycle. And then what are you going to do? You're going to do all that. You're going to build the best company in the industry, and then you're going to sell it. That just doesn't make sense to me. I'd want to own that company forever and compound on that advantage for decades to come.

Claim

Our differentiated value proposition as an acquirer — permanent capital plus deep applied AI engineering that deploys day one — resonates strongly with business owners, and we encourage rollover equity so founders and management participate in the upside.

Taubman explains why Long Lake wins deals and is often the preferred buyer. The value proposition combines permanent capital with an AI engineering team that embeds in the acquired company from day one. They also encourage significant rollover equity for founders and management, creating alignment and allowing sellers to participate in the AI-driven upside.

transcript

Alexander Taubman: We have had a really good, our message has really resonated with business owners and management teams, I think, because I think it is solving a really important need, which is having a long-term permanent capital partner is already a wonderful thing. But having that partner with deep applied AI engineering expertise and a platform that you can deploy day one. Because these folks never see anything like that, right, in terms of the industries that they're currently in. Yeah, we have to, you know, AI is very, very under penetrated. It's probably around 1% penetrated in terms of real enterprise AI use cases. And when you think about sort of the, you know, the overall economy, first of all, 99% of businesses in America are small businesses, and they don't have access to the resources of big companies. But even big companies, are having a hard time figuring out how to drive maximum impact from AI. So we are sort of a, we're solving many needs. And in terms of the philosophy I mentioned before of, we've kind of tried to design the product you want to use as if we were a seller or if we were a management team, to be the optimal partner. And that's how we've designed Long Lake. And so we have this cross-functional team. They become your partners day one. I mean, you get to partner with Varun or you get Varun, Taras, Pratik, and Jason and our extraordinary engineering team will basically live in your office for the next two years, helping you fix all your problems. It's a pretty good value prop. And so, and then we also encourage rollover and equity alignment from existing shareholders or management and founders. And so in our first for verticals, service lines that we've gone into, we have significant rollover participation from the original founders and leaders.

AI transforms the growth economics of labor-intensive service businesses by making existing teams 30-40% more efficient, so companies can grow with high incremental margins like software companies rather than facing a punishing marginal tax rate on new hires.

Taubman explains that labor-intensive service businesses face a structural problem: growing 20% requires hiring 20% more people, and most incremental revenue goes to labor costs — a high 'marginal tax rate' on growth. AI changes this by making existing teams 30-40% more efficient, enabling them to handle more customers without proportional hiring, transforming the business into a high-margin growth model.

transcript

Alexander Taubman: I'll tell you, so this is kind of a non-obvious thing that I've observed, which is actually most of these service companies are growth oriented. And most of these founders built these companies from their bootstraps over 20, 30, 40 years by knocking on doors and, you know, figuring out how to, you know, convince people to use their service in a certain market. But it's actually now, it's really painful to grow because in these industries that are very labor intensive, if you grow 20%, you might need to go hire another 20% people. And then you got first, you got to find them, you got to train them, then you have to manage them. And if you're already making a lot of money and you're kind of, you know, you don't, you know, it's this, and then by the way, so you do all that work to hire those people, and then you only keep 20 cents on the dollar of every incremental dollar of revenue that comes in because, you know, most of it goes to incremental labor. So that's like a very high marginal tax rate essentially on the growth activity. So what we've done with AI is when you make your existing teams 30, 40% more efficient and they can handle more customers, it changes the whole mindset of the organization. Now you're growing, you look like a software company now where you're now growing with high incremental margins and that allows you to invest more in growth, be more growth oriented.

Mechanism

AI eliminates the painful growth constraint in labor-intensive service industries by making existing teams 30-40% more efficient, which transforms the marginal economics from high-labor-cost growth to software-like high-incremental-margin growth, unlocking a growth mindset throughout the organization.

Taubman explains a non-obvious dynamic: in labor-intensive services, growing 20% traditionally requires hiring 20% more people — a painful process with poor marginal economics (keeping only ~20 cents per incremental revenue dollar). AI changes this by making existing teams 30-40% more efficient, creating software-like high incremental margins that fuel further growth investment.
