about TestFlow
the OS for hardware validation
we build the layer between
plain English and your bench
TestFlow is a deep-tech company building AI-native automation for chip and electronics validation: reusable workflows, real instruments, clean data, and a test that reruns on the next revision.
a Delaware C Corp building validation infrastructure, in pilots with fabless semiconductor and hardware teams across the US, Europe, and Israel

Why TestFlow exists
validation is the bottleneck,
not design
Every breakthrough in chips, energy, automotive, robotics, and medical devices rests on testing that is accurate, repeatable, and fast. That testing is still done by hand.
Hardware validation is slowed by manual bench work, brittle scripts, tools that do not speak to each other, and knowledge that lives in one engineer's head. The cost is not one lost afternoon. It is a launch date.
We exist to change that, by making lab testing automated, reusable, and owned by the team rather than by whoever wrote the script.
the vision
hardware innovation, not slowed by testing overhead
The next decade is hardware: AI compute, electrification, autonomous systems, industrial robotics, next-generation connectivity. Validation has to become engineering infrastructure rather than a set of manual experiments.
start for freecategory, not feature
We are not building a better script editor. We are building the infrastructure layer validation runs on, the way CI became the layer software ships on
AI-native from the ground up
The agent is not bolted onto a legacy tool. It writes the workflow it runs, which is the only reason nothing is lost between intent and instrument
the problem
The bottleneck is not design. It is validation velocity.
As parts get more complex, validation cycles get longer and every small inefficiency multiplies across the team. These are the five we hear on every call.
Instrument setups repeated hundreds of times
Mapped once. TestFlow answers every VISA address on the bench and every workflow reuses that map.
Tests rewritten for every silicon revision
Written once. The same workflow reruns against the next revision and the results line up against the last.
Results spread across scripts, spreadsheets, and screenshots
One place. Every run lands against the workflow that produced it, with the limits it was checked against.
Knowledge locked in one engineer's codebase
Team-owned. Workflows are shared and versioned, so the bench does not stop when one person is out.
Weeks between a datasheet and a test plan
An afternoon. Upload the datasheet and the planner maps the coverage, parameter by parameter.
principles
How we build
Four rules we have not broken yet. They decide what goes into the product and, more often, what stays out of it.
Repeatability wins
If you cannot repeat it, you cannot scale it. Everything TestFlow produces is built to be run a second time.
Automation should be reusable
A test is not rebuilt for every revision. It is versioned, shared, and rerun against the next part.
Engineers deserve leverage
Time belongs in measurement and insight. Nobody was hired to babysit a driver stack.
Labs need systems, not stacks
Fewer disconnected tools, one shared workflow. Integration is the product, not an afterthought.
Speed with trust
Faster cycles only count if the data stays reliable. Everything above is subordinate to this one: a workflow that runs in seconds and cannot be trusted has made the lab slower, not faster.
who we build for
Built for the bench, and honest about the rest
TestFlow is for teams whose work ends in a measurement. If your workflow never touches an instrument, we are the wrong tool and we will tell you on the first call.
Validation and post-silicon teams
Bring-up, characterization, regression testing, and the revision cycles that follow them.
Embedded hardware teams
Device testing, system verification, and the reliability workflows that have to survive a schedule.
Research labs
Repeatable experiments, consistent logging, and results a second person can actually reproduce.
Not simulation-only work
TestFlow runs on real instruments taking real measurements. If nothing is plugged in, it is the wrong tool, and we would rather say so.
