About us · Founded 2025

We build the software
we were missing ourselves.

Terra Flow Systems came out of a single observation: biogas plants are still run much the way they were 20 years ago. We are changing that, with the operations platform for the biogas and green gas industry.

Our story

One question
turned into a product.

01
STARTING POINT
An industry at a standstill
There were technical improvements at the plants, in efficiency, in substrates, in sensors, but real innovation in plant operations was missing. The central question stayed unanswered: how do you run a biogas plant so that it is future-proof, transparent and automated?
02
THE REALISATION
Robert Schweizer draws the conclusion
Robert Schweizer, managing director of BioPower GmbH and therefore of the largest biogas producer in Austria, saw it clearly: without digitalisation and automation the industry has no future against cost pressure, regulation (EAG, RED II/III, SURE, ISCC, THG) and the shortage of skilled staff.
03
2023 · THE PROTOTYPE
From BioPower outwards
Together with the technical experts Ing. Mag. David Hess and DI Philipp Weisskopf (p.how Solutions) he developed a solution of his own, at first only for BioPower plants. One solved problem after another, until the whole of plant operations ran through the system.
04
2025 · FOUNDING
Terra Flow Systems GmbH
The tool for a single group of plants became a product for the whole industry, with the mission of digitalising and automating the biogas and green gas industry in Austria, in Europe and worldwide.
05
2026 · AWARD
digi4Wirtschaft project of the year
Together with Terra Flow Systems, BioPower wins the vote for the best digitalisation project of 2026. In the public vote held by the province and the Economic Chamber of Lower Austria, the Retz site took 29.6 per cent of the votes, and twelve projects were up for the vote.

How do you run a plant
so that it is future-proof, transparent
and automated?

– The question TFS began with
The founders

One from the plant,
two from software.

TFS came out of a business that had the problems itself. What the system does today ran first in our own plants.

Managing partner, TFS

Robert is a self-made manager who worked his way to his knowledge as an entrepreneur. Over the years, practice, projects and responsibility gave him a deep understanding of markets, innovation and running a company.

His career is marked by successful projects, from co-developing insulating concrete to building up a modern car sharing model and establishing high-grade recycled soil in food retail.

Today he runs BioPower GmbH, the largest biogas producer in Austria, as managing director, and he is responsible for the move from electricity production to biomethane, the largest biogas conversion project in Austrian history with a volume of more than € 27 million.

Ing. Mag. David Hess
Co-founder, TFS

David is an industrial engineer (HTL Hollabrunn) and a graduate in communication studies (University of Vienna). As co-founder and managing partner of p.how Solutions he has been responsible for product development since 2015, as a fullstack developer, requirements engineer and analyst.

His strength lies in combining technical depth with management experience in software development. At TFS he puts that to work digitalising processes thoroughly and building future-proof solutions for the green gas industry.

Sustainable energy occupies him outside working hours as well.

DI Philipp Weisskopf
DI Philipp Weisskopf
Co-founder, TFS

Philipp studied business informatics (TU Wien). He has been an entrepreneur and software developer for many years. He founded companies of his own early on, led international IT projects and, with p.how Solutions, builds digital solutions for large customers such as ÖBB and A1.

He grew up with his family farm supplying biogas plants, so he collected first-hand experience early.

His strength: translating complex problems into pragmatic digital solutions. With TFS he wants to make the biogas and green gas industry more efficient, cheaper to run and fit for the future.

Our mission

Digitalising the industry,
wherever it stands.

We start in Austria, where we know the plants inside out. Biogas does not stop at the border, and TFS grows along with it as soon as the first plant on the other side comes on board.
