I invested in Hunter's startup, and have been helping out as CFO for some time. He is extremely self-motivated and a very hard worker. We have also been friends for many years and he has always been this way. Always grinding and exemplifying discipline on a level that most do not. I invested in him not only because I believe in the idea, but more so because I believe in him to make it happen.

★★★★★

Hunter is a high energy full stack dev and comes highly recommended. I hired him to help me build out an MVP of a web app idea of mine with some very tricky backend requirements and he performed well, even when I was too busy to supervise closely or give sufficiently detailed instructions. He's very smart and a very good communicator with a good sense of software craftsmanship. You're advised to hire him now before I book him again for my next round of work!

The Perfect Loop

Every great agent runs in a loop — observe, act, measure, improve. We engineer that loop until it's perfect. Not chatbots. Autonomous systems that decide, ship, and run the work for you.

We're embedded with Spring Global's Innovation Team leading GenAI product development — agent factories, multi-tenant RAG, BYOM routing across Azure AI Foundry. Our $10k agent replaced a $100k SaaS proposal.

At Intek Plastics, a US manufacturer, we're extending their Epicor ERP — .NET 8, production scheduling, the brownfield work that keeps factories running. Two ends of the spectrum. Stack: whatever closes the loop fastest.

Common questions

Quick answers before you ping us.

How fast can you ship an AI agent into production?
Most agents reach production in 15–30 days. Discovery is 2–3 days, strategy 3–5 days, build 7–15 days, deploy 2–5 days. We use Claude Code and tight feedback loops to keep iteration fast.
What does an AI agent actually do?
Our agents are autonomous systems that observe a workflow, act on it, measure the result, and improve. They sync ERPs, process invoices, generate reports, run technical support, and replace whole SaaS workflows — without you in the loop.
Do you replace SaaS tools or work alongside them?
Both. At Spring Global we replaced a $100k SaaS proposal with a $10k custom agent (400% ROI). At Intek Plastics we extend Epicor ERP with custom .NET features. The right answer depends on your stack.
What's the difference between this and "vibe coding" with ChatGPT?
We engineer the loop. Real systems need observability, retries, evals, security, and integration with the messy reality of your data. Anyone can prompt; we build production-grade autonomous systems.
Where are you based and who do you serve?
We work with US and international clients. Our stack is whatever gets closest to the perfect loop — Claude Code, MCP servers, .NET, Python, Node.js, RAG pipelines, vector databases.
