Abacus’ Chief Investment Officer Elena Plesco opened her Investor Day remarks with a question that seemed simple: What is Amazon’s largest revenue-generating business?
Most people in the room said AWS, and as we’ve found, most people think that. But it’s not true. Amazon’s largest revenue business is core commerce: selling goods. That’s the oldest part of Amazon, and frankly, not its most exciting endeavor. AWS, meanwhile, is where a disproportionate share of the profit comes from. Revenue engine and profit engine are two different things, and the relationship between them is the whole story.
AWS didn’t even exist for Amazon’s first decade. And it wasn’t the product of a strategy offsite where someone decided Amazon should become a cloud company. It came from necessity. Amazon needed to build technology infrastructure to operate its own e-commerce marketplace at massive scale. Over time, that internal infrastructure became so valuable that companies far beyond Amazon wanted to use it.
The core revenue engine funded and necessitated the infrastructure that became one of the company’s most valuable assets.
As you may be guessing, this exercise was meant to provide a lens for understanding Abacus’ business strategy and operations.
The Rails, Not the Parts
Origination is our largest revenue engine today. It brings policies, clients, and data into our ecosystem. It’s unglamorous. But unglamorous, durable businesses are exactly the kind that compound over decades. And origination is precisely what allowed us to build LifeARC. We didn’t wake up one day and ponder how cool it would be to develop some new technology. We needed data with depth, mortality insight rooted in real transactions, and verification that would strengthen our core business.
Just as AWS came from inside a retailer, LifeARC came from inside an origination company.
The crucial mistake would be viewing Abacus through any one of our individual businesses. What matters is how the pieces connect. Elena talked about how owning the rails, i.e. the infrastructure, lets us interweave our businesses so they reinforce one another.

As I’ve written here before, this flywheel drives our efficiency and profit: Origination brings assets, clients, and data into the ecosystem. Abacus Intel takes that data and builds personalized lifespan models for underwriting and pricing. Abacus Wealth helps clients access liquidity from their policies while building long-term financial plans. Asset Management packages our insights into institutional-grade products that generate recurring fees.
Crucially, Abacus owns the rails. We neither wait for someone else’s deal flow nor rent someone else’s data. We set the terms. And those rails allow us to provide consumers with liquidity, put forward institutional-grade products, and build recurring economics for shareholders.
The Investment Thesis
As Elena made clear, LifeARC is not an insurance tool. It’s a way of turning lifespan into a personalized, quantified financial input. We’ve spent decades getting precise about risk, return, correlation, volatility. We’ve modeled markets to the basis point. But when it comes to the most important input in any person’s financial life, we settle for an average. We solve a deeply personal 40-year problem by applying the lifespan of a population the person doesn’t even belong to.
LifeARC makes retirement drawdown decisions, annuity strategies, and glide paths personalized to how long your money actually needs to last, not how long someone else’s money lasted.
The company that owns the most accurate, most defensible view of individual lifespan will own the input that everything else runs through.
Nobody looked at a bookstore in 2004 and saw the backbone of the modern internet. Infrastructure stories tend to look ordinary right up until they look inevitable. Our goal isn’t to participate in lifespan-linked finance as it emerges. It’s to build the rails the entire category runs on.
