What Wattflow does
Wattflow is a Nantes, France-based technology company (founded circa 2024–2025, 1–10 employees) providing an IoT and AI-enabled HVAC optimization platform for small and medium-sized commercial office buildings of 500 m² and above. The company positions itself as a lower-friction alternative to traditional Building Management Systems (BMS), targeting an addressable context where buildings account for an estimated 43% of French energy consumption (per the French Ministry of Ecological Transition, 2024) and HVAC systems represent over 70% of in-building energy use, while the French Tertiary and BACS Decrees are tightening compliance pressure on building owners and operators.
The product is a three-component integrated stack: (1) the Wattflow Box, an edge computing device that collects 200+ real-time data points per minute from HVAC equipment and strategically placed sensors; (2) the Wattflow Gateway, a proprietary protocol-agnostic device compatible with all major HVAC brands and standard manufacturer communication protocols; and (3) the Wattflow Cloud Platform, which applies AI-based prediction and energy optimization logic trained on proprietary guidelines for thermal comfort and efficiency, incorporating weather, building inertia, energy prices, and real-time CO2 emissions into continuous active optimization. The underlying technology was co-developed with European research laboratories, with patent-pending IP and Deeptech certification from BPI France (French Tech Emergence, 2025).
Wattflow operates a sales-led, consultative go-to-market centered on direct engagement through "Talk to us" and "Simulate" CTAs on its website, targeting building owners, operators, tenants, and networks of specifiers primarily within France. Revenue mechanics are a hybrid model: a one-time hardware and commissioning fee (partially subsidized via French Energy Saving Certificates/CEE) plus a recurring annual subscription for cloud optimization, monitoring, and ongoing support. The subscription is intended to be self-funded by energy savings, with the company claiming customer ROI in under one year.

Wattflow product offering
Product offeringCore offering
Wattflow provides an IoT and AI-based HVAC management platform for commercial office buildings. The solution combines proprietary edge devices (Wattflow Box and Wattflow Gateway) with a cloud-based AI optimization platform that collects over 200 real-time data points per minute to automatically coordinate HVAC equipment, reduce energy consumption, and maintain occupant comfort.
Product overview
Wattflow offers a unified smart energy management solution for office buildings comprising three integrated components: the Wattflow Box (edge sensor and data collection hardware), the Wattflow Gateway (protocol-agnostic HVAC communication device), and the Wattflow Cloud Platform (cloud-based AI optimization applications). The system collects real-time data from sensors and HVAC equipment, uses AI-based prediction and energy optimization logic to coordinate building climate systems, and delivers continuous automated management without requiring on-site operators. The solution is designed to complement existing BMS systems or operate independently in buildings without prior automation infrastructure.
