A Berlin-based team committed to making surveying and documentation accessible to everyone.

In 2018, Robert Gregat and Jan Rentsch, both with over 24 years of experience in surveying and digital solutions, founded the company netpipe. Together with an interdisciplinary team from science and technology, they are developing the product www.3tag.ai, an AI-based platform for digitizing infrastructure data.
Our mission: To use state-of-the-art surveying technology, geoinformatics, and software development to create the basis for the digital value of infrastructure assets and enable the sustainable use of infrastructure data.

3tag stands for the digital future of infrastructure assets.

With our own hardware and networked software (AI-based from 2026), we are creating a precise digital memory underground — for safe, efficient, and data-driven planning.

Our goal is to rethink digital surveying — accessible, precise, and scalable. We enable companies to efficiently record their infrastructure, make it visible, and use it in a data-driven way. In this way, we are creating an intelligent foundation for the construction and utilities world of tomorrow.
