Virtual environments & RL-gyms

We can help build, manage, and scale high-fidelity reinforcement learning environments (RL-Gyms) where your agents can learn to reason, plan, and recover from errors.

How we can help

Robust Testbeds

Environments that replicate your target deployment - a Unix shell, a Salesforce CRM sandbox, or a live e-commerce site replica.

Get In Touch

Engineered Failure

Tasks specifically tuned to a ~50% failure rate. We engineer the difficulty curve to maximize learning efficiency, avoiding flat gradients from tasks that are too easy.

Get In Touch

Deterministic Replay

Version-controlled environments to help replay a failed run 1,000 times to debug exactly why the agent failed.

Get In Touch

Full-Stack Logging

Deep instrumentation capturing HTTP requests, Console logs, DOM trees, and Screen pixels to debug "silent failures".

Get In Touch

Safety Sandboxing

Network-gated environments with mocked external services, allowing agents to train on "dangerous" tasks (like rm -rf or SQL injection) with zero risk to production.

Get In Touch

Automated QA

Tool-enabled checks for rubric adherence, logical consistency, and environment invariants.

How it Works

Get started

Gym Construction

We deploy containerized testbeds and code the "rules
of the game" - defining immutable success criteria (e.g., "The database record must exist").

Get started

Expert Calibration

Before the agent starts, our
in-house Subject Matter
Experts (SMEs) perform the tasks themselves to set the "Human Gold Standard" baseline.

Get started

Telemetry Verification

We verify that our instrumentation captures
every keystroke, API call, and DOM change required to reproduce the human expert's path exactly.

Get started

Hybrid Collection

We run your agent through
sets of scenarios, from simple "Happy Path" tasks to complex edge cases.

Get started

Audit & Delivery

You receive versioned datasets containing the full state-action history, the reward scores, and the replayable environment seeds.

Frequently asked questions

Is it possible to integrate with our existing evaluation system?

Yes, we can plug into your existing containers or API endpoints, or we can host the environment entirely for you.

Why use human experts for simulations?

You need a "Human Gold Standard". Before the agent starts, our experts perform the tasks to set the baseline for what "correct" looks like, ensuring you aren't training towards a moving target.

What is the "Sweet Spot" for failure rates?

We design RL tasks specifically tuned to a ~50% failure rate. If a task is too easy, the gradient is flat. If it’s too hard, the agent learns nothing. We engineer the difficulty to maximize learning.

How do you handle dangerous commands?

We use Safety Sandboxing, i.e, network-gated environments with mocked external services so agents can train on dangerous tasks with zero risk to production systems.
