Hearthstone builds and operates custom AI agents for businesses that need a thoughtful steward — not another big tech software platform. We learn how you actually work, then build the AI agent workflows that handle them.
We shadow your operations for roughly a month — observing the work as it actually happens, mapping communication patterns, and surfacing the bottlenecks no one has time to articulate. This is the part most automation skips, and it's the part that makes everything else possible.
We construct the agent workflows in dedicated, isolated infrastructure with scoped access only to what they need. Each client environment is fully segregated. The system is reachable through channels you already use — text, email, voice — so there's no new tool to learn.
We manage the system on an ongoing basis. As the work evolves, the workflows do too. New capabilities, new edge cases, new integrations — handled in conversation, not in tickets. The relationship is the product.
Hearthstone is built to serve a small number of clients well. We work with operators where coordination overhead is real, the workflows are particular, and the data is sensitive enough that a generic AI platform isn't an option.
Our background is in AI at the largest technology companies in the world — including time at Google, leading AI transformations for Fortune 50 enterprise clients. The conviction behind Hearthstone is that the most valuable AI work is no longer at that scale. It's the careful, bespoke kind that a small practice can do for a small number of clients who deserve the attention.
Service businesses where coordination, communication, and follow-through are the bottleneck. General contractors, real estate teams, short-term rental operators, professional services firms.
Operations where success depends on coordinating across many parties simultaneously. Property management companies, event production firms, agency-style professional services, healthcare practices.
Title companies, escrow officers, boutique law practices — operations defined by deadlines, document chasing, and stakeholder coordination across many open matters at once.
The biggest reason serious operators don't adopt AI is not capability — it's trust. Where does my email go? Who can read it? What happens if the vendor pivots? These are reasonable questions, and they have to be answered before any of the work is worth doing.
Every Hearthstone client runs on isolated infrastructure under their own credentials. Your data is never commingled with another client's. We don't train models on your information. Your system can be exported or wound down at any time, and you'll always know exactly what your agents have access to.
We're not building a platform. We're a small team of operators that builds and runs a system for you.
This is the difference between a consumer AI tool and a bespoke practice. A platform optimizes for the average user. A practice optimizes for you.
Hearthstone takes on a small number of new clients each quarter. If your operation has grown to the point where coordination has become its own full-time job, we should talk.
A short note about your operation is the best place to start. We respond to every inquiry within two business days.
