Blockether builds systems your auditors can sign off on
We design, build, and operate software for regulated industries — end to end, accountable for what we ship. Our engineers built and ran core systems inside one of Central Europe's largest banking groups.
What We Do
We cover the full lifecycle — from the first architectural decision to years of dependable operation.
- Product Engineering
- Complete web, mobile, and desktop products, end to end. Design is part of engineering, not an afterthought.
- Data & Integration
- Dependable pipelines that move data between core systems — correct, traceable, and on time.
- Agentic Systems & AI
- Production AI with guardrails, evaluations, and full traceability — built for environments where "mostly right" isn't acceptable.
- Architecture & Platform Design
- Independent technical judgment before you commit budget — including the questions your IT and security teams will ask.
- UX & UI Design
- Interfaces designed alongside the systems behind them — clear, accessible, and consistent from the first wireframe to the shipped product.
Open Source
We contribute to the Clojure ecosystem with tools born from real project needs.
How We Work
AI under control, not on autopilot
Our engineering process uses LLM agents to plan, write, and review code — inside strict guardrails, with evaluations at every step and mandatory review by a named engineer. Nothing ships unreviewed. And we build our agent tooling in the open, where your team can inspect it.
Spec-driven, agent-friendly codebases
Executable specifications, strict schemas, honest tests. The result is code that humans and AI agents can both navigate — and that outlives the people and models that wrote it.
Weekly demos, not status reports
Progress you can click. Every week you see working software and steer the project on facts, not forecasts.
Ready for your IT review
We expect your IT department in the second meeting, not the last one. Security posture, data handling, architecture and API documentation — prepared before you ask.
Start with a conversation, not a commitment
A 30-minute introduction tells you honestly whether we can help — and what a well-scoped first project would look like. If we're not the right fit, we'll say so.
