Agent systems
Assistants that carry out real errands end to end — placing calls, handling correspondence, running scheduled work — with the guardrails and hand-back paths that make them safe to leave running.
Archerfish Holdings LLC · Independent software studio
We build AI systems that do the work, not demos of it.
A studio in the Bay Area. We design and ship applied AI software end to end — from the first sketch to the system running in production.
01
Studio
Archerfish Holdings builds applied AI software, drawing on a decade of work on AI products and the tooling designers and engineers use to shape them.
Most AI work stops at the demo. The interesting part starts after it: the retries, the edge cases, the moment a model has to act on someone's behalf and be trusted with the result. That is the work the studio takes on.
A small number of engagements a year, shipped end to end.
02
What we build
Interfaces for models
Tooling that gives designers and operators direct, legible control over model behaviour, instead of a prompt box and a shrug.
Evaluation and prototypes
Short builds that answer one question about a product idea, with the measurement in place to tell whether the answer held.
