About Dryad Networks

Dryad Networks is an environmental IoT startup that provides solutions for the ultra-early detection of wildfires and for monitoring the health and growth of forests. The company was founded in 2020 in the Berlin-Brandenburg region of Germany by CEO Carsten Brinkschulte and co-founder Marco Bönig. Brinkschulte, a serial entrepreneur in the telecommunications industry, was inspired to find a technological solution to combat wildfires after witnessing the devastating fires in the Amazon in 2019 and his daughter's involvement in the Fridays for Future climate movement.

Dryad's core product is Silvanet, a large-scale IoT network designed for deployment in remote forests that lack mobile network coverage. The system uses solar-powered sensors with embedded AI to detect the gaseous composition of the air, including hydrogen and carbon monoxide, which are released during the initial smoldering phase of a fire. This allows Silvanet to detect wildfires in under 60 minutes, a significant improvement over traditional camera or satellite-based systems that can take hours to detect a smoke plume. The sensors are non-invasive and do not use batteries, instead relying on supercapacitors and solar panels to eliminate fire risk.

The Silvanet infrastructure consists of several key components: the AI-powered Wildfire Sensors, solar-powered Mesh Gateways that create a distributed LoRaWAN mesh network, and Border Gateways that connect the forest network to the cloud platform via cellular, ethernet, or satellite. This cloud-based dashboard allows clients to monitor forest conditions, receive real-time alerts with geo-coordinates, and analyze data. Beyond wildfire detection, the network can be expanded with third-party sensors to monitor various ecological metrics like tree growth, soil moisture, and fuel moisture levels.

Dryad operates on a B2B model, selling its Silvanet system through a global network of resellers to public and private forest owners, government agencies, utilities, and infrastructure companies. The business model involves the sale of the hardware and an annual subscription fee for the cloud platform. The company has secured significant funding from various investors, including eCAPITAL, Toba Capital, and TIME Ventures, and has received grants to further its technology. As of early 2025, Dryad has customers in over 20 countries and is expanding its deployments globally. Looking ahead, the company is developing an autonomous drone-based system, codenamed "Florian," designed to suppress fires at their inception.
