AI makes software fast.
We make it right.
Specification-led, review-bound AI workflows under named senior engineers. Per-milestone delivery — buy one phase at a time, stop wherever you have what you need. You own everything we ship.
Per-Milestone Delivery
Buy one milestone at a time. Stop wherever you have what you need. You own the source code, prompts, workflow definitions, and documentation we deliver.
Not sure where to start?
Have only an idea? Start at Specifications. Need something to pitch or test? A Prototype. Going to first customers? An MVP. Taking it to market? An MLP. You can stop after any milestone.
Per-milestone delivery
Core focusSpecifications
A precise technical spec written by a senior engineer — usable to brief any team, not just ours. 1–2 weeks. €1,500–€3,500.
Prototype
A working bootstrap of the core idea, shaped enough to validate or pitch. 1–2 weeks. €2,500–€7,000.
MVP
A real, usable Minimum Viable Product for first customers or fundraising. 4–8 weeks. €9,000–€20,000.
MLP
Minimum Lovable Product — polished and shippable to market. 8–16 weeks. €20,000–€45,000.
Beyond launch
Maintenance
Monthly retainer for monitoring, minor fixes, and small changes after handover. From €450 / month.
Continuous Agentic Delivery
Post-MLP retainer where the agentic workflow keeps shipping features under our supervision. €1,500–€3,500 / month + €2,500 onboarding.
Private AI Platform
Your company's own ChatGPT-style workspace — hosted in the EU, connected to your internal systems and APIs, with sensitive data filtered before any prompt reaches a model provider. Setup from €4,500, then from €250 / month.
Capabilities & stack
AI Agents & Automation
Custom AI agents, LLM integration (OpenAI, Anthropic, open-source), RAG systems, document processing, and intelligent workflow automation.
Full-stack Engineering
React and Angular frontends. Django, Phoenix, and Supabase backends. Production-grade applications, end to end.
Cloud & Data
AWS infrastructure, Docker / Kubernetes, PostgreSQL, vector databases, and serverless deployments — built for EU data residency.
Example engagements
Validate an idea
Specifications + Prototype — roughly 3–4 weeks, around €4,000–€10,000. Enough to pitch, test, or decide.
Ship to first customers
A focused MVP — roughly 6–8 weeks, around €12,000–€18,000. Real software your first users can pay for.

Things We've Built
Working software as proof: Praximos in live preview, and Taxisfox in production.
Praximos
A domain-agnostic platform for ingesting obligations, routing them to executors, and collecting structured proof of resolution. Now in live preview — working software, built with our specification-led, review-bound method.
- AI-personalized executor outreach
- Auditable resolution and event trail
- State-machine workflows for any obligation
Taxisfox
Multi-tenant financial document platform for Greek small businesses, entrepreneurs, and accountants. Built end-to-end with our specification-led, review-bound ASD method.
- AI-powered document metadata extraction
- AADE-MyData integration & deadline reminders
- Multi-tenant, role-based, EU-hosted
Tools we built, and gave away
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 dual-mode time tracker: an MCP server that lets AI assistants log work in natural language, plus a keyboard-driven terminal UI. It turns git commits into worklogs automatically.
github.com/Techthos/clockworkA 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.
github.com/Techthos/microstoreTypeScript helpers for the Greek tax authority's AADE-MyData APIs — the right way, the easy way.
github.com/Techthos/yourdataA declarative YAML-to-PDF generator and Go library, powered by maroto v2.
github.com/Techthos/gofolioA tool that runs HTTP actions from simple YAML definitions, to automate and test web workflows.
