What M&P Group does

M&P Group, operating under the SIERA Alliance brand, is a Germany-headquartered environmental engineering company founded in 1981 and based in Bad Wiessee. The group describes itself as Germany's largest environmental engineering organization, employing more than 800 specialists across over 30 locations in Germany, Austria, and Switzerland. Service lines span climate, environmental protection, water, ecosystems, circular economy, urban sustainability, infrastructure, and impact technologies, delivered through a network of partner engineering firms including MP Ingenieurgesellschaft, Tucher und Partner, ICP Ingenieure, BURMEIER INGENIEURE, Seecon, and Taberg.

The technology backbone is SIERA Core, a proprietary infrastructure platform for planning, managing, and delivering projects across the ecosystem, supplemented by the SIERA Periodic Table of Impact ESG framework and SIERA NanoAqua, an advanced water and wastewater treatment technology targeting contaminants such as PFAS and microplastics. The business operates three primary revenue streams: environmental engineering and consulting services delivered through partner companies, fund management via the Luxembourg-regulated SIERA Impact Growth Fund (an 8-year vehicle offering an 8.0% base return plus up to 3.75% bonus), and investor-driven real estate development through SIERA Real Estate focused on brownfield transformation, with 250,000+ m² GFA of residential space delivered. Complementary sub-brands include SIERA Academy (training and certification), SIERA Impact Events (community and webinars), SIERA Agency (central coordination), SIERA Magazine (thought leadership), and Mustard Seed (philanthropy).

Go-to-market is enterprise field-sales oriented, targeting environmental engineering firms, impact investors, real estate developers, and municipalities/utilities across the DACH region. Distribution combines a multi-firm engineer partner network, regulated fund offerings, and direct real estate development. No revenue, funding, ownership, or leadership data is publicly disclosed, and no AI/ML capabilities are evidenced in the input.
