We started Lepton because we wanted to do work that mattered, on its own terms. That meant building a firm where every engagement is led directly by a credentialed principal — not pitched by one and handed to a junior team. It meant treating disclosure as a management discipline, not a reporting chore. And it meant connecting actuarial science, climate finance, data analytics, and healthcare policy under a single roof, because that’s how the real questions arrive.
Why “Lepton”
In physics, a lepton is an elementary particle — small, fundamental, indivisible. We chose the name to remind ourselves that the work, no matter how complex, comes down to fundamentals. Methodology you can defend. Numbers you can trace. People you can call directly when something is on fire.
The work we like best
We do our best work where actuarial discipline, quantitative finance, and policy meet — places where regulators, boards, and the public will all eventually look at the same numbers and ask whether they were built right. We have particular depth in healthcare policy and reform, sustainable finance and ESG, and the actuarial work that underwrites both. We publish what we learn.
Where we go next
The firm has grown to operate across the United States, Africa, and the Caribbean. We are building out the SAFARI tool ecosystem — software, systems, and solutions that let our methodology travel further than our calendars do. We are training the next cohort of credentialed actuaries through internships and fellowships. And we are still, deliberately, boutique.
