Where Claims Operations Starts
Isomer was founded on a simple observation: the most consequential moments in a claim happen before the claim is ever opened. We built a signals layer for that moment, for the inbox not just another workflow.
For decades, insurance technology has transformed the policy workflow — pricing, quoting, underwriting, binding, policy issuance, billing, renewals, endorsements, claims handling, payments, and reporting — yet the point where some of the early indicators of risk arrive, the inbox, has remained mostly manual.
Adjusters read. Adjusters route. Adjusters decide what makes it into the system. And because the system only sees what gets entered, everything upstream of that entry is invisible by default. Signals get missed. Decisions lag. Exposure builds on Day 0 and isn’t recognized until Day 3, or later, or never.
This gap persisted because the tooling to address it didn’t exist. The inbox is the last unstructured entry point in the claims workflow, and until now, no one had built infrastructure to read it.
Most systems operate after a claim is created. We operate before.
Our customers are carriers, TPAs, and self-insured enterprises. They operate in regulated, high-accountability environments where outcomes are measured by policyholders, regulators, and boards. We brought enterprise infrastructure expertise. Our customers taught us insurance. We designed Isomer around what they showed us matters most.
Our Value Pillars
Surface Signals That Never Make It In
We surface critical risk signals buried in emails, letters, attachments, and threads before they are missed or delayed.
Return the Experts to Their Expert Work
We give adjusters time back by reducing manual inbox triage, routing, and data entry so they can focus on judgment and outcomes.
Eliminate the Long & Lossy Filter
We reduce handoffs, delays, and inconsistency between receipt and recognition — bringing speed, visibility, and control to the earliest moments of a claim.
Leadership
Isomer is led by founders with decades of experience building enterprise software for complex, regulated workflows — and the conviction that insurance deserves the same caliber of infrastructure.

Sean Chou
Sean has spent two decades building software for the operational middle where processes are human-powered. As founding CTO of Fieldglass, he built the vendor management platform that Fortune 500s run on today, taking it from zero to a $1B acquisition by SAP. At Catalytic, he co-founded a pioneer in intelligent RPA, acquired by PagerDuty.
Sean started Isomer because he’d seen the same pattern twice before: expert professionals buried in manual work that purpose-built infrastructure could solve. Insurance had the same problem in a regulated, high-stakes environment — and agentic AI made it possible to build something that couldn’t have existed five years ago.

Sean Casey
Sean builds product and technology for regulated industries where expert humans do complex work under pressure. He co-founded Shiftgig as CTO in 2012, growing it into a venture-backed labor marketplace. He later led technology and product at divvyDOSE, a technology-enabled pharmacy, through its acquisition by Optum.
At Isomer he is applying those lessons to insurance, an industry where the operational complexity runs deeper, the expertise of adjusters matters more, and purpose-built infrastructure is more overdue than anywhere else he has worked.
Sean started Isomer because he’d spent his career building technology for environments where the stakes are real, the processes are human-powered, and generic tools fall short. Insurance fit that description — and the emergence of agentic AI meant the infrastructure could finally match the complexity of the work.
