We build the software
intelligence runs on.

Harckenstone is an AI company. We craft our own products, like Bifrost, and build custom software for companies and founders who have an idea and need it made real.

HEIMDALL

The security layer

The guardian inside Bifrost, enforcing your policies and keeping credentials away from the model on every call.

MIMIR

The knowledge base

Unified context across your tools, so agents understand the whole business instead of a single app.

Custom software

From idea to delivery in 3–4 months

Have an idea for a product or an internal tool? We take it from a first conversation all the way to a shipped, working system, timeline depending on complexity.

BUILT WITH AI

Flexible, and fast to change

Because AI is woven through how we build, we adapt quickly when your requirements shift, turning new ideas around in days instead of weeks.

TESTED BY AI

Nothing ships with a known issue

Every build is exercised by our internal AI testing tools before it reaches you, catching problems while we work, so what we deliver is genuinely production-ready.
