Customer privacy
Boundary, retention, access, and evaluation requirements must be explicit before model work begins.
Local AI Infrastructure
Private AI systems for teams that need control.
Random Walk designs and implements local AI infrastructure, private data workflows, and customer-controlled deployments for small teams, studios, and companies working with sensitive systems.

Technical focus
Local AI, private data, implementation support.
We work close to the implementation surface: architecture, prototypes, deployment, review, and handoff.
Commercial secrets
Boundary, retention, access, and evaluation requirements must be explicit before model work begins.
Patent-sensitive R&D
Boundary, retention, access, and evaluation requirements must be explicit before model work begins.
Regulated workflows
Boundary, retention, access, and evaluation requirements must be explicit before model work begins.
Edge latency
Boundary, retention, access, and evaluation requirements must be explicit before model work begins.
Air-gapped systems
Boundary, retention, access, and evaluation requirements must be explicit before model work begins.
FDE method
Work close to the real environment.
FDE keeps engineering close to actual data constraints, runtime paths, and user feedback. We collaborate on-site when needed, and remotely when that is the better way to move fast.
Step 01
Private data boundary
Source categories, movement constraints, retention rules, and review expectations are mapped before training begins.
Creations
Products for local, private infrastructure.
Random Walk builds products for customer-controlled workflows, local data infrastructure, privacy-preserving execution, and settlement-aware coordination.

Services
Capability areas for constrained systems.
Private AI systems, local data infrastructure, deployment architecture, privacy boundaries, and customer-controlled infrastructure.
Dataset Preparation for Model Training
Convert domain material into structured Train / Validation / Test datasets that can be reviewed, versioned, and used for local model adaptation.
Deliverables: Dataset package · Dataset manifest · Split rationale
LoRA Adapter Development
Train adapters for customer-specific tasks and deliver them with training records, model references, evaluation summaries, and activation notes.
Deliverables: LoRA adapter · Training configuration · Training run record
Fused Model Delivery
When contracted, package tuned behavior into privately licensed fused models for customer-controlled environments.
Deliverables: Fused model artifact · Private license terms · Deployment notes
Evaluation & Evidence
Produce reviewable evaluation artifacts so security, compliance, and engineering teams can reason about model behavior before deployment.
Deliverables: Task evaluation · Regression checks · Test set summaries
Private Deployment
Deploy model systems across Apple Silicon, on-prem GPU servers, private cloud, customer VPC, air-gapped systems, and edge devices.
Deliverables: Deployment runbook · Runtime configuration · Access path
FDE Support
Support remote and on-site implementation, especially while a private model workflow is being introduced into real use.
Deliverables: FDE introduction support · Remote engineering support · Support handoff
Security
Boundaries, evidence, responsibility.
Private deployment, least privilege, audit logs, evaluation evidence, and ownership are part of the delivery, not afterthoughts.
Constraint registerCaptures privacy, compliance, and deployment constraints.
Dataset manifestDocuments sources, transformations, exclusions, and retention.
Training run recordCaptures model, dataset, adapter, runtime, and parameters.
Evaluation reportPreserves behavior tests, benchmark results, failures, and limits.
Deployment runbookExplains installation, access, monitoring, rollback, and ownership.
Change logTracks model, data, adapter, and runtime changes over time.
Heritage
A technical studio, not a software shelf.
Random Walk works like an engineering studio: understand constraints, design the structure, verify the result, then hand the system into real operation.
