NestLab Tech — A founder-led AI studio in the EU. Four flagship SaaS products, one open-source project, AI automation services.
Studio first. We build our own products and take on a limited number of client contracts each year. The studio is the product; the work is what the studio is good at.

Four ways to work with us. Each one starts with a few sentences about the problem. Detail on nestlab.tech/services.
| Service | What it is |
|---|---|
| AI workflow automation | Lead routing and follow-up, document intake, reporting, internal alerts and approvals. Where a step needs judgement we add an LLM step with guardrails and a human-review path. |
| Custom AI software development | A production-ready first slice in four weeks: auth, one core flow, deployment, monitoring and backups wired from day one. Boring technology, no vendor lock-in. |
| AI integration services | Retrieval-augmented search, assistants and extraction added to software you already run, with evaluation and cost limits so the feature stays predictable. |
| EU AI Act compliance | We build and operate the EU AI Act Scanner, an automated assessment for Regulation 2024/1689, and apply the same method to client work. Preparation support, not legal advice. |
Four products under our own brand, plus the open-source project they are built on. Dated case studies on nestlab.tech/work.
