We are HASHLYNK

A team from Carinthia getting more out of every kilowatt hour. With systems and software we develop ourselves, we turn surplus electricity into computing power and usable heat.

Our story

From grid limit to business idea

  1. 2020

    Surplus becomes an idea

    In 2020 Thomas Ebner renovates his parents' house and installs a photovoltaic system. But the grid operator limits how much can be fed in. Part of the electricity is neither fed into the grid nor used on site, and simply goes to waste.

    Thomas is into Bitcoin mining and promptly puts a miner in the basement, powered by exactly this surplus. It quickly becomes clear: the electricity that used to go to waste suddenly has a value, and the computing power even earns more than the feed-in tariff. Soon the entire surplus flows into the miner.

    What remains is a very warm basement and a question: how can this heat be put to good use? This question gives rise to the idea behind HASHLYNK.

  2. 2022–2024

    An idea becomes a team

    Together with Matthias Wagner, the first test systems are built at hydropower plants and PV systems. In 2022 Max Possegger joins and turns the test setup into a product that can be planned, certified and integrated into existing electrical installations. With funding from FH Kärnten, Thomas and Matthias develop the business idea into a business plan in 2023 and 2024, while Max continues to develop the technology. It soon becomes clear that the systems also need their own software: Bernhard Jung and Moritz Schalk join the team as two software developers.

  3. 2024–2026

    A team becomes a company

    In December 2024 the patent for the system and its operating method is granted, and HASHLYNK GmbH is founded in 2025. In February 2026 the first system goes into operation. Today our systems put surplus electricity to use at very different sites, from residential buildings and commercial businesses to a 1 MW ground-mounted PV plant.

What we stand for

Plan thoroughly, deliver quality, work honestly

For us, Bitcoin mining is the missing piece of the puzzle in energy technology. To make it fit cleanly into every system, we work according to three principles.

  • Plan thoroughly

    Every site is different. That is why we first check the surplus profile, heat demand and grid situation. We only recommend what really fits and pays off.

  • Quality from Austria

    From development to production, we rely on the highest standards. Manufacturing takes place together with our production partner PMS Group. Brand-name components and certified technology ensure safe operation and clean integration.

  • Work honestly

    Returns from Bitcoin mining depend on the price and network difficulty and cannot be guaranteed. That is why we calculate different scenarios based on reference and average values and discuss all assumptions openly with you.

What sets us apart

Electrical engineering, software and mining under one roof

As an electrical machine engineering company, we combine electrical engineering, software, heat recovery and mining expertise in one team. This lets us support every project from design to commissioning.

  • HASHLYNK talking to visitors at the trade fair stand

  • Electrical and plant engineering

    Project planning, control cabinet construction, electrical design and automation are all done in-house. They are backed by master craftsman qualifications and many years of experience in plant engineering.

  • Patented technology

    The system and operating method of our EcoHash are protected by patent AT527226B1. All our systems share a dynamic load control that adjusts consumption to the available surplus within seconds.

  • Our own software

    We control and monitor all systems with the HashLink Automation Controller. It is developed by our own software team.

  • Heat recovery built in

    We plan the miners' waste heat from the outset and feed it into heating, hot water or process heat systems via heat exchangers. The hydraulic work is carried out by installation partners, whom we coordinate.

  • Bitcoin mining by conviction

    For us, Bitcoin mining is a marketing channel for energy in its own right. It makes electricity sellable where it is generated, even when the grid cannot take it or pays little for it. Our own operating data since 2020 prove it.

Installation & electricity generation

If known; otherwise we model the PV generation.

Feed-in & remuneration

Ideally state the average of the last 12 months or the expected remuneration.

Several files possible. For surplus feed-in, an annual amount or a usable annual profile is required. PDF (up to 2.5 MB) or CSV.

No file selected

Consumption

Not to be confused with grid import alone.

Several files possible. CSV files only.
