About Intergrid

Heat and steam are used in almost every industry for various purposes in various temperatures. Today, most of this heat is still produced by burning fossil fuels, making industrial heat production one of the largest emission sources accounting for >30% of all European CO2 emissions.

At Intergrid, we are on a mission to make electrification and optimization of industrial energy use as easy and economical as possible. As industrials electrify and get exposed to the complex and volatile power markets, operating varying electric-hybrid systems with energy storages effectively exceeds human capabilities.

Intergrid’s full-stack AI autopilot combines proprietary data and control layers with real-time decision-making to optimise industrial heat and steam production and power trading 24/7, safely and reliably.

In two years, we’ve grown exceptionally fast from three founders with an ambitious vision to an amazing diverse team of >30 people from different nationalities and a wide range of satisfied customers across multiple industries. Today, more than 70 industrial sites already rely on our services – and the pace is only accelerating.

To accelerate our growth, we have secured >10M€ in funding from top-tier US and Finnish investors such as True Ventures, Lifeline Ventures, Risto Siilasmaa, and the founders of Aiven. This allows us to continue expanding the team on all fronts with top talent passionate about tackling complex challenges and driven by curiosity and kindness.

We enjoy active collaboration and want to get to know our teammates beyond their Zoom profiles, so we would love to see you at our office located in Kalevankatu 30, Helsinki, as often as possible. Still, we all appreciate the possibility to work remotely from time to time.
