AI makes software fast.
We make it right.
A lean, founder-run studio in the EU. Every line an agentic workflow produces is reviewed by a named senior engineer — you own everything we ship, and you can stop after any milestone.
Three ways to work with us
Pick the engagement that fits where you are — a new product built the right way, a rescue for a codebase that stopped scaling, or your own private AI platform. Each has a dedicated page.
Agentic Software Development
Specification-led, review-bound AI workflows under named senior engineers. The methodology behind every Techthos engagement.
View servicePrivate AI Platform
Your company's own ChatGPT-style AI platform, hosted in the EU, connected to your internal systems, with sensitive data redacted before it ever reaches a model.
View serviceVibe-Code Rescue & Rewrite
We take vibe-coded and AI-generated codebases that stopped scaling — spaghetti files, no tests, fragile changes — and refactor or rewrite them into software you can defend, with quality ensured by tests and senior review.
View serviceWhat you can count on
The same four commitments hold on every engagement, whichever service you choose.
Named senior review
No agent output reaches you unchecked. A named senior engineer reviews every change against the specification and is personally accountable for what ships.
Per-milestone, stop anywhere
Buy one phase at a time and stop wherever you have what you need. Each milestone is a standalone deliverable — no obligation to continue.
You own it on payment
Source code, prompts, workflow definitions, and documentation transfer to you as each milestone is paid. No lock-in, ever.
EU data residency & DPAs
Hosted in the EU by default, DPAs signed as standard, full sub-processor disclosure, and a clean handover with runbooks.

We open-source the small, general-purpose tools we build for ourselves. It is how we contribute back — and the most honest proof of how we build.
A single-binary local store for our Go micro-apps: browse a GitHub catalog, install verified release binaries, manage installs, and scaffold new apps — via both a terminal UI and an MCP server.
