• Founded in 2012 by Dr Klaus Vossenkaul and Dirk Volmering, Membion is a developer and manufacturer of a highly disruptive membrane bioreactor (MBR) solution, with applications in the municipal as well as industrial wastewater treatment sector
  • The product, secured by multiple patents, addresses key problems of modern wastewater purification by:
    • Reducing energy demand by c.90%
    • Requiring substantially less space (c.75%)
    • Leading to superior water quality
    • Ultimately leading to high saving in operating costs


  • DC Advisory was engaged by Membion to assess and execute strategic options, with a key focus on the identification and introduction of Membion’s disruptive solution to potential investors
  • DC Advisory ran an extensive process to identify the best partners for Membion – providing strategic advice, preparation of relevant marketing documentation, support in the negotiation phase, and due diligence coordination


  • In December 2023, Membion successfully completed a funding round led by TechVision Fonds and Deep Tech & Climate Fonds, investment funds with a focus on early-stage and technology-driven companies
  • Through this funding, Membion intends to use the funds to ramp-up its production capacities and expand its market reach
  • This transaction further enhances DC Advisory's strong track record in equity fundraisings for innovative ventures and its clear commitment to support companies with a strong sustainability focus

"With the current financing round, we are setting the course for the efficient scaling of Membion. With TVF and DTCF, we have partners on board who share our vision and will support us in achieving our goals."
