About
Sigil Labs is a software and AI studio that builds Service as Software: systems with AI agents that perform the work instead of only supporting it. We forge digital artifacts that reshape how you work.
The name
A sigil is a symbol charged with intent. Drawn correctly and activated properly, it creates change in the world. That is what code does, and with AI agents, code now performs services that once required human labor. Every system we build is an intention written with precision and put to work. Complex under the hood, effortless in your hands.
What we do
Our main offer is Service as Software. Traditional software hands you a tool and leaves the work with your team. A Service as Software system delivers the outcome: AI agents carry out the steps of the service, and people approve the points where a decision matters.
Around that offer sit four services that can also be hired on their own: custom software, AI and LLM solutions, infrastructure and operations, and security and audits. The services page describes each one and lists the projects that demonstrate it. Those projects are real, both our own products and work for clients, and some clients are not named, for confidentiality.
How we work
Four principles show up in the projects published on this site, from our own products to work for clients:
- One role per agent. Each agent has a single function and access only to the tools it needs.
- Human approval at decisions. The system executes; a person approves the points where the choice has consequences.
- An auditable record. What was done, by which agent and on what basis is kept.
- Stage stated as it is. Each project shows the stage it is really at, from proof of concept to production, internal tool or delivered client work, without rounding up.
We speak plainly about what each system already does and what it does not do yet. The language of forging and craft is a metaphor; the results described on the project pages are real.
Trillium Group
Sigil Labs is a Trillium Group company, alongside Taltos (protection) and Augur (guidance). The group is the ecosystem Sigil Labs grew out of. Within it, Sigil Labs is the one that builds: it turns ideas into functional digital artifacts that work autonomously.
