# Octave.energy’s €10M Series A: Profitable Batteries Meet Grid Congestion

> SPDG Growth led Octave.energy’s €10M Series A (equity + flexible debt) after €16M 2025 revenue and three profitable years — Belgian BESS+EMS expansion into NL, France, and Germany.

**SPDG Growth** led a **€10 million** Series A for Mechelen’s **[Octave.energy](/startup/octave-energy)** in early **September 2026**, structured as equity plus flexible debt, with imec.istart, BNP Paribas Fortis, and KBC participating (Made in, n24).

**Spine:** this is **expansion capital for a profitable installer-led BESS+EMS business**, not a pre-revenue climate science bet — grid congestion is the demand driver.

## Key facts

| Field | Detail |
| --- | --- |
| Company | [Octave.energy](/startup/octave-energy) |
| Round | **€10M** Series A (equity + flexible debt) |
| Lead | SPDG Growth (Périer-D’Ieteren family office; seed returner) |
| Other | imec.istart, BNP Paribas Fortis, KBC |
| 2025 revenue | **€16M** (company) |
| Profitability | Three consecutive years (company) |
| Deployed | **200+ MWh**; **400+** businesses |
| Named customers | Colruyt Group, McDonald’s, Eneco, Naturgy, Nextensa |

## Who uses the product — and for what job

**Users:** industrial sites, SMEs, and agricultural enterprises fighting **grid congestion**, peak prices, and electrification constraints.

**Job:** pair first-life **LFP batteries** with Octave’s EMS so sites can store power, cut peaks, coordinate EV charging, and monetize flexibility — with the customer free to choose their market optimizer (company).

CEO Maxime Snick’s framing (Made in): electrification of heat, industry, and transport is colliding with **net congestion** as the bottleneck.

## Why now

- Western European summers and industrial electrification made capacity constraints operational, not theoretical.
- Banks in the syndicate (BNP Paribas Fortis, KBC) fit asset-backed clean-infra stories better than pure software VCs.
- Proceeds: NL / France / Germany sales-service hubs via installation partners; EMS/asset-management platform depth.

## Why SPDG — portfolio fit

SPDG already backed the seed and is doubling down on a **cash-flowing hardware+software** operator. Bank participation signals underwriting comfort with receivables and project economics.

**Likely founder rationale:** raise patient expansion capital from an existing family-office lead that understands Belgian industrial GTM, plus banks that can support working capital as deployments scale.

*SPDG Growth, imec.istart, BNP Paribas Fortis, and KBC are not in our fund directory — editorial only.*

## Competitive map

| Approach | Tradeoff |
| --- | --- |
| Utility-scale storage only | Large projects; misses behind-the-meter SME pain |
| Pure EMS software | Asset-light; depends on third-party battery quality |
| Commodity battery installers | Price competition; weak software moat |
| Octave BESS+EMS integration | Higher attach; execution-heavy multi-country rollout |

## What is not proven

- Exact equity vs debt split inside the €10M not disclosed.
- Valuation not disclosed.
- Gross margin on hardware vs software mix not disclosed.

## Practical takeaway

- **Founders (climate):** Profitability plus named logos changes Series A conversations in Europe’s selective climate market.
- **Investors:** Diligence partner-installer quality and service uptime — the moat is ops, not slides.
- **Operators:** Relevant if grid connection delays or peak tariffs already block electrification plans.
