Weco - the Wave Energy Collective

What Weco - the Wave Energy Collective does

Weco - the Wave Energy Collective is a privately held Dutch startup founded in 2023 and headquartered in The Hague, Netherlands. The company develops modular wave energy converter (WEC) technology for the blue economy, converting the natural orbital motion of ocean waves directly into rotational energy to drive a generator. Its core products are the Kaizen WEC, a small-scale modular converter based on the Japanese Kaizen philosophy of continuous incremental improvement, and the Denshi WEC, designed to generate power even in very small sea states to enable baseload offshore generation. Supporting offerings include the E-Sea Charging concept (offshore charging stations for autonomous maritime vehicles, funded by an EKOO grant) and the Seanergy Prediction Tool for wave energy forecasting. A proprietary drop-and-pull installation technique enables deployment from small vessels without cranes, achieving operational status in 32 minutes during an offshore test at Scheveningen in April 2025.

The company targets three primary use-case segments: blue economy and offshore energy operators (primary), island communities and remote facilities, and autonomous maritime vehicle operators. Its go-to-market is enterprise and government-focused, pursued through direct engagement with strategic partners such as Rijkswaterstaat and through validation programs including TEAMER in the United States. The business model is B2B/B2G with hardware sales of wave energy systems supplemented by professional services; pricing is not publicly disclosed and is quote-based, tailored to custom project requirements. The firm is pre-commercial, with cumulative funding to date anchored by a €600,000 seed round in October 2025 from NEW-ttt fund, Init Power B.V., and Cyriel de Jong, supplemented by an earlier UNIIQ investment, the EKOO TSE Electricity grant, and TEAMER technical assistance, with open-sea trials scheduled for 2026.
