About
Full-stack engineering. Owned outright.
Limestone Labs is a boutique technical consultancy. Full-stack engineering, cloud infrastructure, AI systems, and AI-assisted marketing. We work directly with founders and technical leaders. No agency layers.
Engagements are fixed-scope, not open-ended. We write production code, configure your infrastructure, and hand it off with documentation. Source code, deployment configurations, and access credentials are yours from the first commit.
Services
What we build
Cloud Infrastructure
Infrastructure as code, deployed to your cloud accounts from the first run. We configure deployments, manage identity and access, and document the architecture. You receive the keys.
AI Integration
Server-side AI integrations and workflow automation built to your operational requirements. Model selection, prompt configuration, and data handling run on your infrastructure.
AI Agents
Autonomous agents built to reason and act across your existing tooling. We design the orchestration layer: task routing, memory, tool definitions, and guardrails. Deployed to your accounts.
