Principles

How we work.

Four anchors. Every product and every contract is tested against them.

01

Real products, not decks.

Everything we ship has paying users or measured adoption. No "coming soon" with nothing behind it.

02

EU data residency.

Cloudflare edge. EU Polar payouts. Brevo for transactional email. Customer data stays in the EU by default.

03

Stack you own.

Next.js, FastAPI, PostgreSQL, Drizzle. No vendor lock-in. Our customers can migrate off without rewriting.

04

AI scoped to measurable hours.

We add LLM calls where they save a documented hour, not for show. Every AI feature has a measurable ROI.

Customers

Who we build for.

Four kinds of buyer, one pattern: someone doing skilled work by hand and ready to stop.

01

Compliance teams

EU AI Act Regulation 2024/1689 ahead of the 2 Dec 2026 hard deadline. CTO + DPO + procurement.

02

Recruiters & HR

High-volume CV processing with audit trail. Tired of formatting eating real hours every week.

03

Job seekers

ATS-aware resume optimization. Working professionals who want their CV to actually land interviews.

04

Real-estate PropTech

Brokerages and PropTech platforms needing semantic listing search with ROI and CMA valuation.

Flagship products

Four products, one studio.

Currently shipping, in development, or imminent. Each is a live app — not a roadmap.
