Company
About us
Hartchain AI Lab builds practical AI software for developers and security teams.
Hartchain AI Lab was founded in 2024 by Peter Maina, founder and managing director, to help businesses and teams adopt AI with privacy controls, predictable costs, and software that runs on their terms, not only in the cloud.
Products are designed for private deployment: your keys, your workspace, your logs. Architecture and governance are built for teams that need accurate, source-backed answers without sending sensitive data to generic cloud chatbots.
- Deputy ships for Windows and macOS; Sentinel is Windows endpoint software
- Per-seat and per-endpoint licensing with volume and enterprise terms
- Support and training for rollout, configuration, and day-to-day operations
- Deployment in cloud, private VPC, or on-premises when data is sensitive
Products
Software you can install today
Deputy runs on Windows and macOS. Sentinel runs on Windows endpoints. License per seat or per endpoint. Volume and enterprise terms available.
Endpoint · Windows
Sentinel
Per-endpoint licensing · Pilot packs available
Lightweight endpoint sensor: Windows service, process and network telemetry, file watch, IOC and behavior rules, optional response actions, and local JSONL logs. Optional AI assist (hybrid mode) adds OpenAI-powered analysis of foreground activity. Your keys, budget limits, and rule-based detections stay in place.
Which product fits?
- Deputy
- Teams who need an AI assistant that works inside a project folder: reading, searching, and editing files with explicit control over what leaves the machine.
- Sentinel
- IT and security teams who need endpoint visibility and local detections without a full enterprise EDR contract, with optional AI assist for activity triage when you enable hybrid mode.
- Both
- Engineering orgs that build software and need both secure development workflows and endpoint monitoring on the same machines.
