Swedish energy tech pioneer Flower has won TECH5 — the “Champions League of Technology.”
The company clinched the title of Europe’s hottest scaleup after developing a novel way to store energy and stabilise the grid.
Flower works with clients running battery storage systems — including EV fleets, home batteries, solar parks, and data centres — to push power back into the grid when demand spikes.
The Stockholm-based business applies its software platform to portfolios of energy assets, uncovering insights that guide storage and management strategies. This improves predictability and flexibility for both energy producers and consumers.
The result is a more balanced energy supply, smoother integration of renewables, reduced reliance on fossil fuels, stronger grid resilience, and new revenue streams for asset owners.
“With a higher share of renewable energy comes a lot of volatility and uncertainty,” said Hampus Jildenbäck, marketing director at Flower.
“The most efficient way to manage that volatility is through battery energy storage, and if we want to rely on a fossil free energy system, we will need to solve a lot of problems — this is the key one.”
Path to the TECH5 title
Flower emerged from a standout shortlist of TECH5 challengers across seven regions: Benelux, the Nordics, DACH, France, Southern Europe, the Baltics, and the UK and Ireland.
From those contenders, our judges selected five formidable finalists: Flower, DataSnipper (Netherlands), Swan (France), Gain.pro (Netherlands), and Turing College (Lithuania).
Each was assessed on growth, impact, and future potential. All five scored highly in each category — but Flower bloomed just above the rest.
Jildenbäck told TNW that the scaleup’s work goes beyond grid stabilisation and asset optimisation.
“We take a holistic ecosystem approach, using our storage portfolio not only to stabilise the power grid, but as an enabler for something bigger,” he said.
“We buy energy from wind and solar farms, use our storage portfolio to manage their volatility and are then able to supply society with cheap, reliable, and plannable green electricity, which has so far been the holy grail of renewable energy.”
Future energy
Flower’s victory in TECH5 was announced today at TNW Conference in Amsterdam.
Jildenbäck described winning the contest as “a true testament to our mission and motivation for keeping the whole team continuing the work we have started.”
Looking ahead, he said Flower plans to expand into six European markets and collaborate with the broader European energy and tech ecosystem “to enable the energy system of tomorrow.”
Winning TECH5 puts Flower alongside some of Europe’s top scaleups. Past winners include fintech giant Revolut, food recovery app Too Good To Go, and online supermarket Picnic. Now Flower joins them, adding fresh growth to the green tech landscape.
