products
focused software for recurring problems across research, coordination, creation, and operations.
Subintern maps and rebuilds consequential workflows for professional-services teams—connecting tools, automating repeatable work, and keeping human decisions visible.

- products
software for recurring problems in modern work.
- automation
systems built around how organizations actually operate.
- applied research
experiments that test better ways of working.
what we’re building
automation
custom systems that connect tools, carry context, and move work forward with less manual coordination.
research
practical experiments into how software and ai can improve the way knowledge work gets done.
why subintern
we start with the work, not the model.
we study how a task moves through people, tools, decisions, and handoffs, then build the smallest reliable system that improves it.
learn more about us- work before technology
we begin with the actual workflow: its people, tools, decisions, constraints, and handoffs.
- judgment stays visible
automation handles the repeatable parts while important decisions remain inspectable and human-directed.
- context carries forward
our systems remember the state of the work, so people spend less time reconstructing what already happened.

prewalk: let cheap models inherit expensive thinking
a coding agent spends most of its budget reading, not writing. prewalk pays a frontier model to do the reading, then hands the warm context to a cheap model to finish the job.

agents are an implementation detail
the useful question is not whether a product has an agent. it is whether the system gives the work a better shape.

the work between the work
the largest automation opportunities often live in the handoffs, status checks, and context reconstruction surrounding the visible task.
