Helios Marine

What Helios Marine does

Helios Marine is a vertically integrated electric marine technology company headquartered in Sofia, Bulgaria, with manufacturing operations in Burgas. Founded around 2019 by brothers Drago and Dimitar Enchevi, the company designs and produces three electric yacht models — the Alpha 14.5m, Omega 7.2m day cruiser, and Sigma 4.5m — alongside a portfolio of marine-grade technology modules: LiFePO4 blade-cell battery systems with IP67 waterproofing, the Helios Marine Link IoT control module (NMEA 2000, 5G, Raymarine/iOS/Android integration), the Helios Digital Switch for remote electrical system control, and modular electric propulsion packages configurable for OEM builders, sailing yachts, and ICE retrofits. The company also offers Fleet Link, a cloud-based fleet management dashboard for multi-vessel operators.

The business operates across multiple revenue streams: hardware sales of made-to-order yachts, batteries, and propulsion packages; subscription/recurring revenue from Helios Marine Link and Fleet Link; and an expanding tiered authorized dealer network with protected territories. Go-to-market combines direct sales, an OEM/wholesale channel targeting other boat manufacturers, and dealer partnerships across Scandinavia, the Netherlands, Germany, Croatia, and Greece, supported by an active presence at major European boat shows (Cannes, Venice) and a dedicated investor relations function following its May 2026 IPO on the BEAM market of the Bulgarian Stock Exchange. Customer segments include private boat owners, charter and fleet operators, OEM boat manufacturers, long-range cruisers, and ICE vessel retrofit buyers.

Following the opening of a 1,100 sqm specialized serial production facility in Burgas in early 2026 and the recent IPO that raised approximately €2.438M at a ~€21M post-money valuation, Helios is transitioning from a startup to an industrial-scale player. It has secured multiple awards (Gussies 2025, Premio Ricerca 2026), a Royal Yacht Squadron partnership, and selection for Stage 2 of the EIC Horizon Europe Programme, while competing in a global electric boat market projected to grow from $3.3B in 2023 to $7.7B by 2030.

Core offering

Helios Marine designs and manufactures electric yachts (Alpha 14.5m, Omega 7.2m, Sigma 4.5m) and supplies integrated marine electric technology including LiFePO4 blade cell battery systems, modular electric propulsion packages, the Helios Marine Link IoT control module, Helios Digital Switch, and Fleet Link fleet management software. The company sells both finished yachts to end users (private owners and charter operators) and technology modules/packages to OEM boat manufacturers and ICE retrofit customers.

Product overview

Helios Marine is a vertically integrated electric marine technology company that operates both as an electric yacht manufacturer and a technology solutions provider. The product portfolio centers on three electric yacht models (Alpha 14.5m, Omega 7.2m, and Sigma 4.5m) that serve as demonstration platforms for the company's proprietary technology. Underpinning the yachts are four core technology modules: Marine Battery Systems (LFP blade-cell technology with integrated BMS), Helios Marine Link (IoT control and monitoring module with 5G/cloud connectivity), Helios Digital Switch (NMEA 2000-based electrical system control), and Electric Propulsion & IoT Systems (modular propulsion packages combining motor, battery, and IoT). The company also offers Fleet Link as a fleet-wide management dashboard for multi-vessel operators. This platform-plus-modules architecture enables Helios Marine to serve both as a boat OEM and as a technology supplier to other manufacturers and retrofit markets.

Broad incumbents

• Volvo Penta: Established marine propulsion and electronics OEM (Volvo Group). Competes broadly in marine power and is investing in electric marine drivetrains — a key incumbent threat on both propulsion packages and integrated vessel electronics.
• Garmin: US-listed marine electronics giant (MFDs, chartplotters, NMEA 2000 ecosystems). Competes with Helios Marine Link on the vessel monitoring / display layer and could extend into integrated boat management at scale.

Direct peers

• Torqeedo: German electric marine propulsion specialist (motors, batteries, integrated systems) acquired by Yamaha. Direct peer on the electric propulsion package and marine battery modules, and a key competitor for Helios's OEM customers.
• Corvus Energy: Norwegian supplier of lithium-ion battery systems for marine propulsion (commercial ferries, offshore, yachts). Closest peer on the marine-grade LFP battery module business Helios sells to commercial vessel operators.
• Vision Marine Technologies: Canadian-listed electric boat and propulsion OEM with E-Motion outboard systems sold to other boat builders. Closely comparable on the B2B technology-supplier model Helios pursues with its Electric Propulsion & IoT Systems line.
• Candela Speed Boat: Swedish electric boat manufacturer using hydrofoils and proprietary battery/flight-controller technology. Competes in the same premium European segment and shares the vertical-integration-from-cells-to-software playbook.
• Silent-Yachts: Austrian solar-electric catamaran builder producing series-production zero-emission yachts. Direct peer in mission (zero-emission cruising yachts) and category (serial-production electric marine vessels) though at a larger scale.
• X Shore: Swedish premium electric day-cruiser maker (Maelstrom, Eelex) with vertically integrated electric drivetrains. Directly competes with Helios in the same European coastal day-cruiser segment and is the closest comparable business model.

Emerging players

• Rand Boats: Danish electric day-cruiser startup with Scandinavian design DNA. Competes for the same coastal leisure customer Helios targets with its Omega 7.2m and Sigma 4.5m models.
• Greenline Yachts: Slovenian hybrid and electric yacht manufacturer with established serial production. Adjacent peer in the European electric family-cruiser segment, though with a hybrid (not pure-electric) focus.
