Water infrastructure = massive opportunity

 

Opportunity

The global market for pumps and related water‑infrastructure was estimated at approximately US$ 60‑75 billion+ — e.g., the global pumps market was valued at around US$ 59.65 billion in 2024. (source)

Financing through the UN, the World Bank, the EU and national governments is growing for distributed, modular water‑ & energy‑infrastructure systems.

The market is fragmented — there is no dominant module/mobile solution for high‑flow remote applications.

Market size

  • TAM (Total Addressable Market): ~US$ 100 billion+ (pumps + low‑head hydro + mobile water systems)
  • SAM (Serviceable Available Market): ~US$ 20‑50 billion (off‑grid pumping, modular hydro systems for remote applications)
  • SOM (Serviceable Obtainable Market): ~US$ 1‑3 billion – our achievable share in 5 years (nothing exaggerated, realistic)
    (Note: These are internal estimates based on publicly available data.)

STEFAN Pump–Turbine – a robust, modular, dual‑mode fluid‑engine:

  • Pump mode for large volumes of water
  • Turbine mode for generating electricity from low‑flow/low‑head conditions
    It is designed for off‑grid, mobile, modular use in agriculture, construction, emergency response and remote areas.

Dual‑mode fluid engine

  • Pump mode: high‑capacity water movement – for agriculture, construction, emergency scenarios
  • Turbine mode: converts flow or pressure into electricity, where traditional turbines fail

Key distinctions

  • Impeller/rotor architecture
  • Dual‑direction drive shaft (mode switching)
  • Modular casing/seals for field adaptation

Current status

  • CAD model of the full unit completed (ready for CNC production)
  • Previous generations of prototypes built (TRL ~2‑3)
  • We have not yet performed full CFD/FEA simulations or large‑scale laboratory validation
  • IP – provisional filings in preparation; architecture and layout are novel


Traction

  • Built 3 generations of early prototypes for flow geometry/internal components
  • Engineering plan for full‑scale unit completed
  • Preparing test model for flow/pressure/efficiency validation (6‑9 months)

Business model

  • Direct sales: hydropower & renewable energy plants, high‑flow pumps for agriculture, civil protection, remote installations, industrial plants and processes, research/energy‑projects, maritime shipping and large vessels
  • IP licensing: OEM manufacturing partners for pumps/turbines (component or series)
  • Public/ESG projects: subsidies, infrastructure projects with pump/turbine modules

Scalability

  • One platform – multiple variants: pump, turbine, hybrid
  • Data/IoT layer: later integration of flow/pressure/efficiency and remote monitoring

Market comparables & strategic reference points

  • Xylem Inc. acquired Sensus (smart pump/IoT metering) for US$ 1.7 billion — shows value of water‑infrastructure IP. (source)
  • Voith GmbH generates over US$ 100 million annually in licensing IP in hydro/pump systems — demonstrates recurring revenue potential.
  • Modular pump/turbine start‑ups have raised €10‑50 million in seed/pre‑A funding — indicates investor interest.
  • OEMs such as Andritz AG and Sulzer Ltd actively seek field‑verified fluid systems.

Funding


We request €300,000 seed investment for execution:

  • Engineering, flow and pressure testing of key components, pilot preparation
    Legal/IP costs and preparatory work for market/pilot partners

Funds distribution

  • Legal/IP/subsidies: ~50%
  • Pilot preparation/reserve: ~50%

Additional strategic investment (€5 M–€20 M):

  • OEM co‑development
  • Team expansion (engineering, regulatory, commercial)
  • Strategic ownership/licensing option

Milestones

  • M0–3: CNC components + instruments
  • M3–6: Assembly + flow/pressure test
  • M6–9: Field pilot + performance data
  • M9–12: Preparation for licensing/OEM deals

Team

Founder: Štefan Marinko – mechanical designer/innovator with experience in prototyping mechanical systems.
Independent development for 3 years; early stage R&D prototypes built.

What we seek:

  • Senior engineer for fluid systems (pumps/turbines)
  • Business development lead with OEM/licensing experience
  • Pilot‑partner for agriculture pump or infrastructure deployment

If you are seeking:

  • an early‑stage project with domain knowledge and market addressability
  • entry into the future of water‑ and energy‑logistic systems
  • collaboration with a team that maintains humility and ambition
