A sandbox your agent can't tell from production.
Not a mock of one API. A whole company — its systems, its people, its counterparties, and a clock that keeps moving. Your agent's first week happens here.
Mocks test calls. Twins test tools. Sandboxes test work.
One endpoint. A canned response.
Tells you the call works.
One tool, with real behavior and state.
Tells you the integration works.
Every tool, the people using them, the parties outside, and time.
Tells you the job works.
Agents don't fail at calls. They fail at work.
Your agent passed every test. Then it met the real world.
Three things an agent can't rehearse before production: who it has to work with, how specific they are, and how long the loop takes.
The other side won't give you a sandbox.
Payers, carriers, agencies, other companies' agents. You can't rehearse against them in production.
Generic isn't theirs.
Their configs, their rules, their quirks. Agents fail on the specifics, not the textbook flow.
The bugs show up on day five.
Rules change, data goes stale, replies come back a week later. A one-shot test never sees it.
Three dials of reality. Most sandboxes turn one. Ours turn all three.
Spin up. Shape. Run forward. Replay.
Pick a template.
Pick a template for the kind of company your agent works in: systems, people, counterparties, other agents.
Structure, never records.
We read structure — configs, schemas, permissions, workflow rules — and generate data that matches their distribution.
The clock moves.
Inject a rule change, a reversal, a slow reply, another vendor's bot. A week runs in an hour.
Rewind to any moment.
Fix the agent, run it again, diff the outcome. Branch from day 3 and try five fixes in parallel.

A company is a cast, not a database.
Real enough to trust.
We replay your last quarter inside the sandbox and count how many real production incidents it reproduces. Every run's real-world outcome flows back in. Each customer makes the next sandbox more real.
Runs don't just go forward. They also go backward — the agent faces replays of what actually happened at your last quarter, and we count how many of those real incidents show up inside the sandbox.
If the match is close, you ship with evidence. If it's off, we tighten the world. Either way, the next customer's sandbox is more real than the last.
Every run ends in a readiness report.
Every run produces a readiness report IT and compliance can read: what the agent did, where it failed, what changed after the fix.
Scored on outcomes, as a function of the trace. Two reviewers reading it agree on what happened.
Test. Proof. Gate. Train. Certify.
Each rung is a different reason an agent earns time in a sandbox like this.
Agents test here while they're being built.
CI for the parts of agent behavior unit tests can't reach.
Teams walk into their first customer with evidence, not projections.
The readiness report precedes the security review, not the other way around.
Enterprises will use readiness as a gate on production.
Procurement becomes a measurement, not a reference call.
Labs will train on worlds that push back.
RL and post-training on environments with people, counterparties, and time — not toy benchmarks.
In time, hours here will count toward sign-off.
Insurers and regulators will recognize simulated hours the way aviation recognizes simulator hours.
Pilots log real hours in simulators good enough to count. Agents should too.
We build the world your agent works in, before it works in the real one.
One world live. The next one is yours to pick.
Four reasons to spin up a company sandbox.
Test before you ship.
Catch what breaks in a sandbox that pushes back, before the first customer demo.
Prove readiness.
Walk into the security review with a report. Days of simulated runtime before anyone sees a demo.
Gate production on evidence.
Evaluating three vendors? Run them through a sandbox of your own operation. Same rules, side by side.
Train on environments that push back.
RL and post-training on environments with people, counterparties, and time — not toy benchmarks.
Spin up your first company.
We'll build a sandbox and run your agent through a week. You get the report. Replies come from the cofounder email, usually within 48 hours.
