What we believe
LLMs will only matter in actuarial work if they can work like experienced, capable actuaries.
Read the model, not just the output
An actuary should be able to open a Gaspatchio model and see exactly what it's doing — no black box, no hand-waving.
Judgment over automation
We build tools that support an actuary's judgment, not tools that try to replace it.
Built for the work, not the demo
Actuarial software has to hold up under audit, under regulation, and under a bad valuation cycle — not just in a sales call.
Gaspatchio
Open-source actuarial modelling. Build models you can read.
LLM-first
Every model is structured so an LLM can read it, reason about it, and work inside it directly.
Actuary-readable
The same structure that works for an LLM works for a reviewer. Nothing hidden in a black box.
Fast runtime
Built to run production-scale actuarial models, not just prototypes.
Open foundations, commercial layers
Opio builds in the open, and builds a business on top of it.
Open source
The core of Gaspatchio is open source, so any team can inspect it, run it, and see exactly how it works.
Managed and supported
Opio also offers managed infrastructure and production support for teams who want Gaspatchio running without owning the operational load.
Company-specific tooling
Not every problem fits a product. Where a team needs something Gaspatchio doesn't cover — a specific integration, a bespoke model, a workflow unique to how they work — we build it directly. This is where Opio's original product-development work lives, now aimed squarely at insurers and actuarial teams. See who we've built for.
