You design the flow.The machine runs it.

CronAI is a founder-led software company in Munich. We take on senior engineering and AI work for client teams, and build tools that keep the person who designed a system able to see what it actually did.

AI that works on your clock. Illustration: a schedule that fires every fifteen minutes, drawn on your local time. The most recent run is marked in amber, the runs still to come in blue.

What you can hire us for

All services

Engineering delivery

Hands-on implementation inside your team: backend and service architecture, APIs and integrations, workflow automation, connected and embedded software. Architecture and code in the same engagement, with explicit interfaces and a documented handover.

Architecture and AI consulting

A bounded piece of work for when the problem is still a decision. You get the decision, the constraints that shape it, the failure modes, the smallest useful experiment, and an implementation sequence — written so you can act on it, not just read it.

What we build ourselves

We run our own software because that is where engineering decisions meet real consequences. We label maturity plainly: a roadmap is not a shipped feature.

  • Open source · MIT · v0.3.0

    schriftsatz (opens in a new tab)

    Markdown to print-ready PDF through pandoc and XeLaTeX, with a text layer that survives copying and extraction, table columns sized by their content, and tagged PDF/A or PDF/UA output. Formerly our internal md2pdf, which sets our own 2025 annual accounts with the footers § 35a GmbHG requires.

    brew install cronai-labs/tap/schriftsatz
  • Open source · MIT · working v0.1

    VaultOre (opens in a new tab)

    A Markdown-native workflow engine for Obsidian. Workflows are notes; they declare their permissions, run in containers, and write results back into the vault. We run it in our own vault, and the code is public.

  • Open source · MIT · alpha v0.1.0

    OKF Vault Kit (opens in a new tab)

    An Obsidian vault that is also an Open Knowledge Format bundle, built around on-device search, a local model that reads and edits the vault over MCP, and the vault as an explicit knowledge graph. macOS, Windows and Linux. An alpha: what is unfinished is written down in the repository.

  • Alpha · waitlist

    cronai.app (opens in a new tab)

    Scheduled AI workflows that report what ran, when, and how it ended.

  • Private prototype

    PortVault

    Local-first handling of financial data. Core and CLI exist as a private prototype — no public repository, no release, no date.

Who you will be working with

Tobias Krug

Founder and Managing Director

More than a decade of software engineering, most of it in automotive and connected systems: backend and service architecture, APIs, containerised systems, embedded and connected software, and applied AI. Through CronAI I do that work directly — and build the tools I want to use myself. Founder-led here means one engineer, who also carries the responsibility.
