Sting gathers 20 years of experience in a free online course for future entrepreneurs

Sting’s latest initiative to nurture future entrepreneurs and attract talent to Stockholm is now being launched: Sting Startup Academy.

Sting’s latest initiative to nurture future entrepreneurs and attract talent to Stockholm is now being launched: Sting Startup Academy.

“The idea behind Sting has always been to contribute to the development of Stockholm as a leading startup hub and create a world-class community for tech companies wanting to grow and make a difference. With Sting Startup Academy, we continue to do just that, by helping entrepreneurs in the making get started with their ideas,” says Pär Hedberg, CEO and founder of Sting.

Sting Startup Academy, a collaboration between learning platform and Sting alumni company Learnster, is aimed at individuals who are curious about the startup scene, perhaps have an idea and entrepreneurial dream, or are interested in working for a tech startup. 

The fundamental value of the course is Sting’s combined experience from having helped over 400 startups develop into sustainable growth companies while highlighting the Nordic way of building a business.

“In the Nordics and in Sweden, we have a slightly different approach to building companies than in many other parts of the world. That is something we want to highlight in Startup Academy and take advantage of as a strong brand in a tech nation whilst sharing our collective experience. We also see this as an opportunity to reach a broader spectrum nationally and internationally,” proceeds Pär Hedberg.

In the Sting Startup Academy, the user is guided by the Sting coaches and well-known profiles such as Jessica Schultz, Partner at Northzone and co-founder of Hello Fresh, Magnus Nilsson, Investor and co-founder of iZettle, and Lisa Ericsson, head of KTH Innovation. 

In 5 hours, you get a thorough overview of topics such as ‘how to test your business idea’, ‘how to get your first customer’, ‘how to build a winning team’, ‘how to succeed in sales’, and ‘how to finance its startup’.

“We are immensely proud that Sting chose Learnster’s learning platform to deliver such a unique project of value. At Learnster we are passionate about sharing knowledge and entrepreneurship. As our own startup journey began at Sting, we can relate to Startup Academy’s target group. Sting’s support for young companies is immeasurable. Therefore, it feels especially good to now get to give back. To come full circle, so to speak,” says Mikael Larsson, CEO at Learnster.

Notable millionaires invest in Swedish zinc-ion batteries that solve raw material supply challenges

• Enerpoly’s seed round raised USD 1.5 million.
• These funds finance upcoming pilot projects that demonstrate the zinc-ion battery technology.
• Investors hail from the financial and industrial sectors in Sweden and the USA and include tech-savvy investors, Fredrik Sidhagen and Johan Nord, as well as bankers, Eirik Winter, Malin Engman and André Rhodin.

Enerpoly recently closed a $1.5 million seed round. Enerpoly develops zinc-ion batteries that offer asustainable solution for stationary energy storage. Investors and angels that participated in the previous pre-seed round reinvested. New investors include known names in the financial and industrial sectors in Sweden and USA, such as Fredrik Sidhagen (CEO of RCO Group), Johan Nord (previously CCO at Trustly), as well as bankers Eirik Winter, Malin Engman and André Rhodin.

– The energy crisis affects everyone. Enerpoly is an interesting company because they are working on solving the very important problems of affordability and supply chain reliability in energy storage. Energy storage development is essential in these times when energy security, access and sustainability are becoming critical for the Nordics, says Eirik Winter, investor.

Enerpoly’s patented technology uses cost-effective raw materials, such as zinc, which can be sourced inSweden and Europe. This can contribute to the region’s global competitiveness within the fast-growing battery industry. Europe is lagging China and USA in securing raw material supply for energy and mobility systems. Zinc-ion technology can help Europe catch up in the global race, in establishing both strategic autonomy and sustainability for its clean energy system.

The raw materials also contribute to the battery’s affordability and safer battery manufacturing. The manufacturing process and components are water-based, meaning they are non-flammable, non-toxic, and non-explosive.

– The battery industry is struggling to set up local supply chains and production infrastructure to ensure future stability. That’s why it’s so important that Enerpoly’s technology is built on globally abundant materials and that we aim to establish battery manufacturing right here in Sweden, with a technology that uses materials that can be sourced in Sweden. In fact, large amounts of zinc were recently discovered in the silver mines of Sala, says Eloisa de Castro, CEO of Enerpoly.

The purpose of Enerpoly’s seed round is to finance upcoming pilot projects that demonstrate the zinc-ion battery technology and enter a fast-growing billion-dollar market. The pilots will be carried out in Sweden, Europe and globally in collaboration with energy storage innovators, such as Polarium, one of the first companies to use lithium-ion technology for the telecom industry. Pilots are expected to commence in 2023.

– The pilot customers make up nearly 10 percent of the global energy storage market. Now they’re exploring Enerpoly zinc-ion batteries for applications that they expect to grow significantly in the next 3-5 years. Together, we can move toward building a future where everyone has access to clean energy, says Eloisa de Castro.

About Enerpoly

Enerpoly develops zinc-ion batteries for stationary energy storage. The company’s patented battery technology solves critical problems with today’s energy storage solutions. Zinc-ion batteries are a safe, sustainable, and scalable battery technology that can enable 100% renewable energy on a global scale. The company was founded in 2018 in Sweden, with growth accelerating with funding from the European Commission (EIC) and the Swedish Energy Agency. Enerpoly is now taking its zinc-ion batteries from the lab to commercial scale, with pilot projects ready for 2023. Learn more at

TeraSi adds third co-founder, closes pre-seed round to drive development of 6G hardware for Earth and space 

TeraSi’s ultimate aim is to build a new technology platform to enable the future of wireless technology at scale. 

The TeraSi team: Adrian Gomez Torrent, James Campion and Bernhard Beuerle 

TeraSi, a Stockholm based deep tech startup developing hardware for 6G applications, has added Adrian Gomez Torrent as a third co-founder and closed its pre-seed funding round to drive the next stage of its technology and product development. TeraSi’s ultimate aim is to build a new technology platform to enable the future of wireless technology at scale. 

Adrian joins TeraSi from beyond gravity, a market leader in the satellite industry, bringing cutting-edge expertise in the areas of antenna technologies and RF hardware for space applications. Adrian also has insider knowledge of all levels of the TeraSi technology platform, having previously worked together with TeraSi’s founding team in academia. TeraSi’s expansion and on-going technology development is enabled by a new private equity funding round which includes notable angel investors and seasoned industry experts, pushing TeraSi’s network and in-house expertise to the next level. 

“When you aim to bring something totally new to the table you need the best of the best on-board. We knew Adrian was the only man for the job – smart, driven and just crazy enough to make this work. We can’t wait to ramp things up together. We’re also delighted to be supported by such a great set of investors in our mission to create a scalable hardware platform.” James Campion, Co-founder 

TeraSi’s pre-seed round comprises new investments from noted angel investors Fredrik Posse, Per Björklund and Stefan Lindeberg and Dominic Davies and Andrew Stentiford (founding partners of Immetric Invest AB) as well as follow-on investments from KTH Holding and STING Holding. The funding allows TeraSi to continue industrialising their technology and start bringing new products to market, while also adding industry, IP and strategy know-how. 

“I am thrilled that Bernhard and James asked if I wanted to join as a third founder. The challenge of taking our technology from academia to the market is incredibly exciting. With my previous experience with this type of technology and in the space industry, my hopes are that I can take us one step closer to the goal of discovering the next revolution in wireless systems,” explains Adrian Gomez Torrent.

TeraSi was founded as a spin-off from KTH Royal Institute of Technology in 2020 by James Campion and Bernhard Beuerle to commercialise unique products developed during their PhD research, where they worked together with Adrian. TeraSi’s hardware offers improved performance at a greatly reduced size and weight, bringing maximum SWaP to demanding wireless applications above 60 GHz. TeraSi designs and manufactures its products in Stockholm and has a range of customers and partners in the test and measurement, space and wireless industry sectors. 

TeraSi is one of the companies in Sting Incubate Deeptech.

Deeptech is trending as Sting kicks off 22 new startups 

Today 22 new startups begin their journey with Sting. As the founders gather for the kickoff at A-house, the trend is clear: the group of deeptech companies is bigger than ever before, and among them a large proportion are female founders and CEOs. 9 out of 10 startups with high-tech innovations have at least one female founder and 6 out of 10 deeptech startups have a female CEO.

“Together with many other players in the ecosystem, we have worked very hard to pull out quality companies within the deeptech sector for several years. Finally, we see the results of that effort! It is particularly exciting to see that, despite a common prejudice about leadership, so many talented women are proving expertise as owners and CEOs,” says Raoul Stubbe, who has coached deep tech companies at Sting since 2006.

“I’d say this is a direct result of very focused work coming for several directions; investors have shown an increasing interest in both high technology and female entrepreneurs. Big influencing partners such as Vinnova and KTH have long worked strategically to bring on more women, and here at Sting, we set the goal of improving the gender balance in our founding teams in 2017. It is incredibly inspiring to have succeeded in that ambition, uniting so many talented women in the same program,” proceeds Raoul.

This year, the quality of the applications has been so impressive, Sting decided to take on more companies than usual. Nevertheless, fewer than 15% have been accepted to the fall 22 programs.

Another startup joining Sting this fall is Mycomine, which develops biological treatment plants where fungi break down pollutants such as oils, diesel and plastics and turn them into biomass.

“We are in an intense phase right now, where we are scaling operations from a laboratory phase, in order to meet the needs of the market. We look forward to, together with Sting, sharpening our business model, to reach established industries with a new, innovative way of thinking,” said Magnus Ivarsson, CEO and co-founder of Mycomine.

CUBO has developed a solution for storing data in DNA.

“The amount of data generated in the world keeps on growing. The way we currently store data is not only very energy draining, and it is about to reach its physical limits.

Despite challenging investment times: Propel Capital VI succeeds to raise capital as planned

35 experienced business angels contribute SEK 15.5 million, matched by SEK 14.5 million from the anchor investor Saminvest, in Propel Capital’s latest addition Propel VI.

Alexandra Tsampikakisis one of the new angels in Propel VI

Propel Capital, Sweden’s most active private investor in tech companies, in collaboration with accelerator Sting, has since its start in 2014 invested in over 175 companies. Despite tough times on the stock exchange, interest was high, and Propel Capital VI was able to close as planned. Propel Capital invests in early-stage startups addressing important challenges especially within Sustaintech, Healthtech, Deeptech, and Digital innovation sectors.

One of Propel Capital’s success factors is the carefully selected composition of business angels. Out of the 35 investors in Propel VI, 24 have been in previous rounds of Propel, and 11 new angels have joined Propel VI

The venture capital company Saminvest is once again the anchor investor, which enables continuity and further strengthening of the ecosystem and business life in this region.

Another factor is the great follow-up investment activity from the angels and so far, over 50% of all Propel’s companies have attracted a follow-up investment from the business angels.

Alexandra Tsampikakis, the co-founder of Edtech company Ugglo, is one of the new investors.

“For me, as an entrepreneur myself and a Sting Alumni, it feels amazing to be able to support the next generation of growth companies through Propel. I am looking forward to being a part of the strong investor network that Propel offers”, said Alexandra Tsampikakis.

Another investor, Ludvig Linge, is also a board member of Propel Capital.

“Propel Capital is an incredible opportunity to gain exposure to a large number of exciting early-stage companies while also expanding my own network with other like-minded business angels. Furthermore, Propel Capital has proven that it is possible to generate returns for investors on the invested capital,” said Ludvig Linge.

Pär Hedberg CEO at Sting:

“It was incredibly important to close Propel VI, in a season where the rest of the world is on shaky ground. With such uncertain economic times, it feels good to be able to offer the companies in our programs an advanced investment as well as access to very interesting follow-up investors. It’s also very exciting that so many of our old propel angels together with anchor investor Saminvest, choose to join again. That, in combination with so many new exciting investors, is incredibly valuable to us. It’s a strong network, which is meaningful to our entrepreneurs to connect with.” More about Propel Capital:
