Data
Get your data clean.
AI is only as good as the data behind it. We start by mapping what data exists, what’s missing, and what must be cleaned before any model can use it. Then we build the pipelines, warehousing, and instrumentation that turn raw data into something a system can reason over reliably.

Code
Find all the gaps + bugs.
We prove the core logic against real examples before writing application code, then wrap it in tools, retrieval, and guardrails. Evaluations (functional, quality, and adversarial) are written as a build artifact, not an afterthought, so failure modes surface before they reach production.

UX/UI
Optimize your user experience.
Behavior that learns needs an interface people trust. We design the human side of AI products (where a person acts, reviews, or audits) and calibrate in production against real usage and feedback, keeping behavior observable: not just what it does, but how it behaves when no one’s watching.

The agentic delivery method
We scope by autonomy, not feature count.
Higher autonomy means higher risk and more calibration. So we place every capability on the Agency Ladder and match the build, the guardrails, and the human role to the level it actually needs.
Copilot
AI suggests (drafts, summaries) and a person acts. Lower risk, faster to ship.
Agentic
AI acts (triage, routing) and a person reviews. Needs strict guardrails and clear SOPs.
Autonomous
AI acts and a person audits. Needs reference data, monitoring, and zero-tolerance evals.
Evaluation is a build artifact, not a final phase: functional, quality, and adversarial evals, with guardrails and human gates. A fix agent never verifies its own work.
Three ways to start
Start where your needs are
AI / Design Discovery
A short, focused sprint: auditing, scoping, and prototyping. A validated plan before committing to a full build.
AI-Native Product Delivery
Our end-to-end model, start to finish: Ground Truth, specs, agents and human review, verification, and a system that keeps improving after launch.
AI-Accelerated Staff Augmentation
Experienced engineers embedded in your team, using AI tools and Rootstrap practices to increase execution capacity without lowering the quality bar.
