The Warrington-based enterprise will use the capital to expand advisory services and commercialise grid innovation products.
"We set out from day one to create a purpose-driven enterprise that made the clean energy transition fair, inclusive and accessible to all. It’s our firm view that no community should be left behind as we strive for a net-zero future."
Most rounds here started life as a press release.
Winfred reads them overnight, pulls out the facts, checks them against Companies House and files them. It was built by C8VA, who do the same kind of work for other businesses: turning messy, unstructured material into something you can search, count and rely on.
The financing round was co-led by Clean Growth Fund and AP Ventures to support facility expansion in Wales.
"We are thrilled to have received backing from both our existing and incoming investors. This oversubscribed round sends a strong signal that UK investors are serious about decarbonisation. We are particularly glad this investment will support the growth of green industries in Wales,"
Felicis led the round with participation from Sequoia and the Westly Group to support workflow expansion and research.
"Supply chains are the least glamorous part of the economy, yet the most consequential, deciding what gets built and what does not. That’s also what makes them so hard to automate.

Air Street Capital led the Series A round with participation from Madrona and Antler.

The British Business Bank led a £10m funding round to support international demonstration projects and research.
"The renewable power market is held back by its vulnerability to external factors. The answer is long-duration energy storage, and Certain Energy has the technology and now the funding to deliver highly efficient, affordable batteries, based on abundant materials, to make this a reality."
